Intake manifold gasket/ spacer

[StreakinOraNgeX]

How come nobody has this mod? From what I hear It does a lot reducing intake charge temps and adding power at the same time. Also a lot of Honda owners especially Rsx owners do this mod as it is relatively cheap and adds power. Any thoughts.

[Stormtrooper77]

A gasket is supposed to do all that? Hmm.

[DSMConvert]

Ive heard of a headgasket spacer, but never an exhaust gasket spacer....

[jersey_emt]

Who said anything about an exhaust gasket spacer?

An intake manifold spacer will add a couple of HP (maybe 2-4)

[StreakinOraNgeX]

No exhaust gasket spacer, but a a intake manifold spacer. Rsx owners buy this from hondata and claim 3.5 hp. For our car I saw a link and it said around 3 hp too.

[ND4MSP]

seems like a good mod. I think one of the kits comes with intake manifold, tb, and coolant bypass kit. Prop be one of my first mods if I ever get around to it. Good way to get to know your engine bay if your not the type to dig like me

[CONEH8R]

People do have it. And we are in the process of developing spacers.

[wicked]

doesn't seen like it would do much for our cars since we have a duel runner setup.because in genaral the longer the runner is the more towards topend your power will be.
I think porting would net better gains then this.

[DSMConvert]

oh haha im an idiot i read the damn thing like ten times and somehow kept seeing exhaust instead of intake....yea that mod does add power but like wicked said we have dual runnes so I'm not sure we'd see the gains like other cars would...

It's not for the length of runner. It's a phenolic spacer used to insulate against conductive heat transfer. An attempt to keep a bit more heat away from the intake air. I have Outlaw's kit, but haven't installed it yet. Hondas with FI use these things a lot, with decent results.

BTW - longer runner = low end power. Short runners are for higher RPM power.

Thinking about porting as well, Brian is getting good results with it.

[MSP Chris]

Yeah I thought some of those gaskets were hard plastic..and they really are not spacers they are replacements, right..?

[StreakinOraNgeX]

[MSP Chris]

Ahh, mainly a better material that does'nt promote the transfer of heat from the head to the intake manifold.

Streakin I have seen articles before for hondas promoting plastic outlined with o-rings a while back claming to drop intake temps...

[starflare21]

there are plastic, metal and phenolic type but the first two were mainly used with domestic engines and carbs. the spacing and the design pattern of the spacer could alter and/or net power gains on those type of motors.

the spacer in focus though for our cars is just to target and promote cooler temps. seems like a logical modfication but never tried it myself.

[BlkZoomZoom]

Try doing what I have done to the intake manifold while you have it off. Oh do this if you only use your vehicle for off road use.

[mspeed101]

I was planning on it, I just need to get a hold of another manifold. I'm new to porting, so I want to do this on an extra. What ones can I use? MP3, P5, or any of the normal Protege manifolds?

[BlkZoomZoom]

Any 2.0l. intake manifold. The Mp3 did not have the shutter valves (thats the only diff. I know of).

Heres a couple of pics. of what I have done....

Groovy, do you happen to have any other manifolds lying around?

[BlkZoomZoom]

I only have the original one off the car. No extras. I'm going to be doing an intake and throttlebody for Ehawley soon.....If you can get ahold of an intake, one more would only be another 5hrs... Unless you have the tools and bits to do it.

[tddelsol]

what are the shudders for???

We've got a decent die grinder and a few bits, I think we need to buy some more. My dremel is somehow missing right now, but I think there are 2 more in the garage. I'll keep in touch, but normally I like to try this stuff out a bit, I'll see if I can find some extra parts so I don't ruin mine... just in case.

[MSP Chris]

Don't know if anyone has air tools around but ingersol and rand (spelling) have an awesome porting set. I can look into getting a part number if need be. By the way those dremel bits are crazy expensive, I'd rather just buy the fitting for my air tools.

[Titanium]

I have the spacers, intake manifold and TB spacers, just waiting to install. I had then installed on my old 2.0L probe and you can really tell the difference with the intake manifold spacers. Before the intake manifold spacer the intake mani would get so hot after a run that you couldnt touch the runners but after the spacer it was much much cooler. You could put your hand on the intake manifold and feel that it was just alittle warm. So as far as performance I would say that it helps because at least you dont have to worry about the heat transfer from the head to the intake manifold.

[StreakinOraNgeX]

On a probe, they rated the hp increase at around 3 hp. On our msp's do you think it will be higher lower or the same hp increase??

[Puckpimp71]

I think it'd be a little bit higher, since we probably have worse heatsoak than the Probe... maybe by 1.5hp, but I think that's on the optimistic side.

[mspeed101]

Either way this looks like a good mod for only $100.

[Titanium]

Like I said it cant hurt and it is sure to help with at least heat transfer from the head to the intake manifold. In theory, if the charge of air was cooled by an intercooler or a cai but then it went into a intake manifold and that charge of air could get heated back up because of the temp of the intake manifold.

[Puckpimp71]

The heat would still radiate from the head to IM but it wouldn't conduct to the IM which will heatsoak an engine faster and leave less time for the radiator to help cool your engine. The air change you're talking about would get heated back up, which is almost impossible to avoid, but it wouldn't be as hot, so I think this is a worth while mod... Kinda disappointed that I don't have $100 laying around for the kit.

[TurfBurn]

I"m working on making gaskets (IM gasket first, then TB, then others if requested) for you guys that should cost less than anything else on the market... I"m having materials brought in and I'll be visiting the machine shop to have proto's made on Friday (don't know when I'll get the protos back though). I'm using a better material than phenolic and working off digital prints that I had laser measured to be exactly accurate for a perfect fit!

I'll keep you guys updated if you are interested.

Thanks!

[StreakinOraNgeX]

Definitely interested keep us updated man.

[TurfBurn]

Well quick bit of background...

We tried some current market spacers on one of our cars and found the fit was terrible. Required a fair amount of dremeling and so forth to get it to fit half decent. Phenolic can be nasty stuff to work on. Also, at the time I don't believe the kit included longer bolts, but it does now which is good to see but our kit will do so as well.

To try and get around those fit issues I went the route of buying a brand new stock gasket and having it laser mapped down to a few thousands of an inch and then we generated solid models of the part from that. Once that was completed we took that to a machine shop we are going to contract to have these parts precision water jet cut. In the time of doing that I found out some of the difficulties of using phenolic and looked into new materials. Ended up finding a polycarbonate polymer that has high enough tensile strength and temperature resistance to be suitable for use in the application. Additionally, it is also 25% more resistant to transfer of heat than the phenolic XX grade that would normally be used by most. This is then going to be water abrasion jet cut by a CNC machine to match our models exactly. From there we are going to be test fitting the first parts, making any necessary adjustments and then selling them from there. I already know what my material costs are, so the remaining cost I need to figure out are the final set of bolts we need and how much our machining services will run us. After I have the I'll be able to come back with a price for you guys. I don't want to estimate now as to where we will come in, but the obvious goal is to provide a better product and still come in reasonably to significantly below the price of existing products on the market.

I'll let you guys know a price range once i get protos in, and then after that I'll give you a final price and an ETA once we have test fit these parts. We hope to/expect to be ready to go in the next 3 weeks as long as lead times at the machine shop are not too long.

Thanks!

[MSP Chris]

awesome work man, they still would be reuseable right?

[TurfBurn]

Yep they will be reusable, and if cost allows I'll also include an extra stock gasket. I've seen these installed with no gaskets, but I'd personally be more comfortable with a stock gasket on either side... so you could use your old one, plus the spacer plus the new one... but I have to see on the cost. A stock gasket is about 12 bucks.

[MSP Chris]

So the stock gaskets are reusable, I mean if the mileage isnt too high.

[TurfBurn]

So the stock gaskets are reusable, I mean if the mileage isnt too high.
Yes and no... technically they should be replaced every time you do things. But in some cases the gaskets are in rather good condition and you can get away with it. Additionally, adding in the plastic spacer will cause a different mating and should seal ok with the gasket. Also, that isn't the most critical of gaskets on the car. If it was a head gasket or oil seal I'd say replace it without question even if you only did 100 miles since the last time. But the IM gasket you can probably get away with pretty safely.

But at the same time, if you are in there doing an install on the spacers you'll realize it is not the easiest thing in the world to drop in so you may just want to replace the 12 dollar part rather than risk a leak of some sort. It's all up to you in the end!

Thanks,

Steve
sales@nsnmotorsports.com

[TurfBurn]

Dropped off materials and drawings for protos today before lunch. I should have 2-4 gaskets in my hands as soon as the machine shop can cut them out. I'll fit them, make adjustments and then we'll be ready to go. Everything now is just turn around time from the machine shop.

The material that is likely to be our primary gasket has 25% better thermal insulating properties over phenolic. So we will be initially starting with 3/16" spacers, and will offer them cheaper than 1/4" spacers which we can also make per request or may have in stock as well.

Thanks guys!

Any updates???

[TurfBurn]

I won't know anything for a couple days. All a matter of when the shop gets to cutting the first samples as part of their tests. Then I'll get a quote, pull in material, and get the first set cut. But I will keep you guys updated as best as I can!

Thanks,

Got word back from the machine shop. I'll have my prototypes on Monday I guess, so about 6 days from now. Then I'll find out what the lead time is going to be and test fit the protos for you guys. Then we'll be set to go at that point.

Later!

Steve

[StreakinOraNgeX]

Any estimated price yet?

[TurfBurn]

Not yet... I will consider it feasible if I can hit a price for you guys in between 40 and 80 bucks... anything above that isn't worth it in the least... but I should know more on Monday when I get the protos. There is a strict setup fee that I have to pay every time I want to run a batch... then there is a machine rental/hour fee I have to pay (something like 120 - 200+ an hour) plus materials. That I have to divide out each time based on the number of parts I get made, and then any other expenses. So that's where the feasibility comes from. If I can do it for you guys in that range then we are golden, and I'll aim as low as I can get us... anything above that range and even the high end of it I consider to be unreasonably expensive unless I hear otherwise from you guys.

Thanks!

Steve

There is some more information in another thread:

But here are some pictures of the finished product. We need to do some testing yet, but then we'll be set to go on them in short order! :)

Looks like the price should be about 50 bucks maybe less. So check out these pics (more in the other thread) and that link for the information!

[peepsalot]

Clear? neato!

[TurfBurn]

Nope :) Tinted! Adds an extra 4 hp just for being tinted right there! LOL :) But seriously there are claims on the market of the part adding as much as 3 or 4 horse on an FS 2.0L. Whether or not that is true, I don't know or really care that much. I know it is beneficial from a standpoint that it helps reduce manifold and TB temperatures and thus keeps the intake charge that much cooler which is beneficial against detonation and also for better performance from a denser intake charge.

Im interested in this as well. So this kit will fit better and keep the intake charge cooler then the outlaw engineering kit? Also will you be including a coolant bypass mod as well?

[Puckpimp71]

It's a totally free mod if you take time to look at the TB. It's kind of hard to get to, but I removed the bottom hose altogether and just looped the top hose to where the bottom one recirculated back to the upper coolant hose. (yippy) TB bypassed absolutely free and in 30 minutes (yippy) now that I've got the IC water sprayer, I've looped hoses from the pump through the TB and back to the reservoir so I can circulate cold water through the TB.

[peepsalot]

Cold water through the TB may not be a very good idea. I think I recall BlkZoomZoom posting about an "incident" he had with that.

[Puckpimp71]

Dug up this thread: http://www.msprotege.com/forum/showthread.php?t=74908&page=1&highlight=water and it appears he didn't have any problems. There was just speculation as to what can go wrong. I wouldn't suggest using ice water all the time, either, as it's more likely to cause stress cracks over time... as long as the resevoir isn't that close to the engine it's colder than the TB and there's going to be some sort of gain. After a good long spray I definetly notice less heat soak related hesitation. Maybe one day I'll get to do a few dyno runs...

[TurfBurn]

Also will you be including a coolant bypass mod as well?We have not done the TB side of it yet. Both kits will fit FAR better than the outlaw kit, and will match or be better as far as keeping the IM cooler. Anybody that buys the intake manifold will get a discount on the TB when it comes out later. So you don't need to worry about "waiting" to get them together. We will be looking into the coolant bypass for you guys of course, and the kit will include it assuming the modification is simple and reasonable (which I believe it is! :) ) Not to mention we are cheaper!!! :) and all about mazda.

I used vacuum end caps from where I work with worm type clamps, I have a very tiny leak on the housing closest one to the 02 connectors....There is a very tiny leak about 3 drops in about 1 month or so.

I used vacuum end caps from where I work with worm type clamps, I have a very tiny leak on the housing closest one to the 02 connectors....There is a very tiny leak about 3 drops in about 1 month or so. I take it that you capped the open nipples for the coolant lines with vacuum end caps once you removed the coolant lines to the TB. And that the lower one has a small leak? Just trying to see if I follow what you are saying.

I have to look at it again, but we will likely provide caps to cap the TB ports so you don't get corrosion and dirt inside of the TB water lines, and then whatever is necessary to get the other lines connected differently.

Installed the first one in a car last night. Part was perfect, and temps did drop (hard to measure perfectly though but about a 12-15 degree drop at least). Also saw that the TB has a SIGNIFICANT impact on manifold temps. You can see the temps rise a good 10 degrees or better when the thermostat opens and coolant moves through (aka when the radiator fan kicks on).

It is very hard to compare against what the other guys claim as you don't know their exact test setup and measuring points. I measured direcly on the head itself right in front of the mating of the IM and head. Then just a couple inches back on the IM for my other point. We also found that highway cruising is not actually the hottest time for the IM and head... it is actually under heavy load at low speeds, like hard acceleration and climbing hills. We did see a marked improvement in temps though, so the product does what it is supposed to! :)

So yea, basically ice water + (ported?) throttlebody = bad idea. But you already knew that ;)

[MSP Chris]

Yea that is exactly what I mean, it is not like a stream coming out, I have never actually seen coolant sitting their just the sopts where it has dried..I don't know if I want to crank down the worm style clamps any more and chance chewing threw the end cap.

Looks like I'll also have TB spacers and hopefully coolant bypasses read for you guys as well. I'm turning the machine shop loose on them this coming week, so hopefully have parts in about 7 days or so.

I had expected the machine shop to be cutting them today or tomorrow, but haven't gotten word. For sure I'll have them in stock by the end of next week including throttle body spacers. I'll have final cost at that point, but as of now it looks like if anything it will go down a bit. So stay tuned!

im interested too. Is there any way once you do the tb coolant bypass mod, that we can incorporate a valve so for us in the winter states dont have to worry about stuck tb. I agree with removing it for summer but id like to see if i can have piece of mind in the winter too. THanks!!

[TurfBurn]

I'm working on that with another northerner up here (fricken cold today too!! 30's)... but It looks like we can do the coolant bypass that doing the switch is less than 5 minutes of work... that way it can be done and undone without much trouble :D!

[terbow]

excellent, im just gathering parts cause im going to do all this with the engine out of the car, but its good to think about. i like hp, but i like amenities too lol

[TurfBurn]

Confirmed with the shop today that they have the parts at the cutter and I should get them on Friday.

Thanks guys!

[BlkZoomZoom]

peepsalot- Just alittle more info. on that "incident". That throttlebody was what you call goin alittle too far. It had a different throttleplate and the bore was literally paper thin ( I could flex the walls with my thumb). With the throttlebody on now (has the lip cut down thin, thats it), I have used the pump after every run...not saying it won't crack, just saying it hasn't yet.

EDIT: price correction

[terbow]

ok just so im clear, does this include the coolany bypass stuff or is that another gb? this is just for the tb and mani spacers correct?

[TurfBurn]

this will include anything necessary for the coolant bypass. At this point from our work we believe it is a free mod done with no extra parts. I'm including covers for the open ports, but otherwise you are just altering the connection. Should this not prove to work out as we expect it to we will include hardware or ship it later free of charge for anyone who needs it. So this is for the whole deal in one shot.

[terbow]

ok, well ill get this, i was wondering, since i havent really ripped this car apart like my other car, if you could just show me a diagram or what part to but on how to put a valve on it that would work well. i can figure it out but its gettin frickin cold and i dont want to really be out there all night testing valves hahaha. with that said ill send over the money tonight. woot.

[TurfBurn]

Ahh.. I didn't realize you meant to have a valve, we were going to just do it as a "switch the hoses and you are done" sort of thing... I'll look and see if I can find the CD with the pictures on it.... otherwise I'll have to figure something out... but the short version on what you'd do is there are two hoses that run from coolant lines to the TB. One comes from the cast aluminum side port on the head (there is a big fitting attached to that) and the nipples comes off the top of that. The other hose comes from one of the brass like lines that wraps around the motor (runs very near the EGR pipe). You just need to disconnect the end of the one that comes from the brass pipe from the TB, and then completely remove the hose that is coming from the top aluminum nipple. (so you take it off the nipple on the aluminum part, and off the TB itself). Then connect the free end of the one coming from the brass pipe to that now open nipple on the aluminum part and you have now bypassed the tb. Make sense or not?

Steve

[terbow]

i think so, pardon the newb questions. i havent had time to look under there really or seen a pic so its a bit confusing, i understand what you posted though. so is there a way to say..... put a valve inline and just be able to shut off the coolant flow for summer or does it have to flow back somewhere? the way it sounds im guessing i cant just pop a valve on one line and shut off the flizow. thanks

[TurfBurn]

You could get away with cutting one of the lines and putting a valve in there. I hadn't thought of that originally, but it is certainly a good idea. So yes that could easily be done, and you'd be fine. It would take care of the flizow fo shizzle.

[terbow]

fa sho! ill do that then, is it ok to send the money now? or are we waiting still. im not installing it for a while but i want to have it.

[TurfBurn]

It's up to you on that. I have the parts. They all look good. So no worries there. You can pay whenever, and all shipments that get payment before Sunday night will go out first thing Monday.

Thanks!

Steve

[terbow]

payment sent. sorry that i wont be able to give a review but at least i got faith in nsn lol one last note..these get torqued to stock specs right?

[TurfBurn]

Yep factory spec torque should be fine! I think it is pretty low anyway.

[TurfBurn]

I have all the parts in and in stock. If you would like yours shipped on Monday please contact me with payment and shipping information by 2:00 on Sunday. You can contact me at any point after that as well and I will ship as soon as possible. But for those of you looking to see them at your door this week I'll be taking payments until 2:00 on Sunday for shipment on Monday.

Terbow, once you get your engine opened up and the plastic cover off, as well as the TB it's much easier to understand the coolant bypass. Took me a few minutes, but it's much easier than it sounds.

[Puckpimp71]

Just got my spacer set in on Tuesday!!! Woohoo! Can't wait to put it in, but alas, I'm scheduled for 65 hours this week, so I think I'll at least get my TB spacer done tomorrow before work. Product was delivered within a week and it's sexy as a IM and TB spacer can be. NSN was great to deal with and between PMs and the website, all my questions have been answered quickly. I'll let you know how the install goes.

[TurfBurn]

I haven't had a chance to do the writeup on the TB spacer install yet, but it is pretty simple and straightforward I think. But if you have any problems, just shoot me a message. It is just 4 12mm bolts (well 2 bolts, 2 nuts) to get it off. There is an IAC and TPS connector to deal with, and the two coolant lines. That should be it for connetions on the TB itself. Hope that helps!

Have a good one and thanks for the positive review!

**** Just did my TB spacer and destroyed my TB gasket. I'm going to my dealer to buy a set for the TB and IM before I continue **** I don't think it's totally necessary for the TB gasket, but better safe than sorry, and with how easily my TB gasket ripped in half, I'm a little worried about the IM gasket. By the way, when you put your STB back on be very careful tightening the nut! I just sheared off a bolt. D'OH! Going to fix it tomorrow.

[peepsalot]

I had two brand new replacement gaskets for my IM when I did mine, and I ended up tearing both of them somehow. In the end i gave the gaskets a big (fu) and used some good ol' gasket sealant.

I'm going to my dealer to buy a set for the TB and IM before I continue **** I don't think it's totally necessary for the TB gasket, but better safe than sorry, and with how easily my TB gasket ripped in half, I'm a little worried about the IM gasket. By the way, when you put your STB back on be very careful tightening the nut! I just sheared off a bolt. D'OH! Going to fix it tomorrow.

You can just RTV it carefully and you'd be set... but that isn't all the easy either. Also, when we installed the IM, we only had a gasket on the IM side, not at the head... the gasket spacers seal pretty well. For the TB I'd say you can get away with the RTV or just a single gasket as well.

I'm surprised you sheared that nut! You must have cranked that baby. I don't remember the torque spec for that... I'll look it up and post it for you shortly.

If anything else comes up, let me know!

Mazda's torque spec for the TB nuts and bolts is 14-18 ft-lbs which is very light when you actually do it (way less than you think in other words). It is the same for the IM as well.

I didn't shear the TB bolt off, it was the STB (strut tower brace)... dammit. It's an easy fix. I'm debating to just drill the bolt out and buy a nut and bolt to put in it or spend a few $$$ and take somewhere to have it done right. Come to think of it, they'll probably do what I was going to do. Oh well. When I took the nuts off I used 60 ft/lbs, so I thought it'd be the same torquing it down... oops. I think 40 ft/lbs is sufficient.

I was wondering what the extra S was on the front of throttle body ;). Glad it will be an easy fix for you though!

[jurgs01]

Just bought this. Probably won't install either till I do my engine rebuild, but always looking for ways to dissapate heat before the compression/combustion process:)

Just got mine yesterday. They look quite nice, but they won't go on for at least a few days. I'll keep you guys posted on my results.

I was wondering how everyone likes this mod? I was supposed to get it a long time ago but never got a chance. Anyone know the gains in power on these particular spacers? Turfburn, maybe you can chyme in.

[TurfBurn]

Well dynos that have been done on FS motors show about 4-6 hp increase. We have not done dynos on our product itself, but I know it matches or exceeds what the dynoe'd products are because of the design and so forth. The biggest gain is really that it is helping cool the overall assemblies and the air temp. We measured temperatures of more then 20 degrees cooler in some cases, more in others, and less in others as well. All in all it's really just one of those extra parts you can do to get some gains and have some improvement and even a little more cushion against detonation overall. It's a cheap modification compared to a lot of things out there... and in fact we have them on special right now for even less than the normal cost!

let me know if that was a good enough answer!

Thanks,

sounds good enough for me, im gonna order them right now!

[TurfBurn]

I got an order.. so I'm assuming that's you :). They'll ship first thing on Monday. I'll provide a tracking number then.

Thanks!

Awsome! this is my next purchase!

[TurfBurn]

the writeup/how to is on our webpage as well in the documents section. The feedback I have gotten on the writeup has been pretty positive. I tried to be extra thorough, so hopefully it works for you!

thanks!

Hey, did you ever get my PM about looking into making these for the SHO?

[TurfBurn]

I'm not 100% sure... I've gotten a number of pm's and requests about making them for other cars... we can do it, but it requires a minimum buy though at the front or it just isn't affordable for us to do it. It would have to be a group guy sort of deal where everyone is in/deposits so we can get going on it... but I'd have to know if it was possible due to the configuration... is it a V motor or is it a inline?

[Puckpimp71]

It's a v motor... The intake manifold looks like a mess of snakes. I'll start a feeler thread at the SHO forums and see what happens. What kind of buy in are you looking for up front?
