well i have a 2.0l and was thinking about boosting but now im a little doubtfull,. how much boost can i run with no problems and i will i have to go with a full engine management or a piggyback system of some sort, i like the hiboost kit but i dont want to blow my protege up.

If you want no problems you probably should not boost.

you should stay N/A
if you want boost under safe conditions (without upgrading engine internals) I would say 6-7 psi is safe amount. Im currently in a process of getting my custom turbo project on the road, and Ill be boosting only 5.80 to 6 psi, as I will be running BEGi FPR, which allows you to run only upto 6 psi I beleive. if you wanna boost more than that, make sure you will get lower compression ratio forged pistons and forged rods, which is a must if you wanna boost big amount of psi. 6 psi is very safe. Take a look at Mazdaspeed Protege.....its exactly the same engine as in any protege that has 2.0 motor, only this one has a turbo, and stock MSP runs 7 psi from factory, so 6 psi is definetly safe as long as you know what you're doing. Hope this helps
If you want no problems you probably should not boost.

uh, yes we can. we both have turbos (or in my case, had two before i traded car), and they are a fucking hassle. youre trying to turbo a car that wasnt meant to be turbod for one, and two, anytime you mod a car with a relatively weak motor, not too much stronger tranny, poopy stock clutch, that came with 98whp and you go and double it - youre asking for problems.
id bet that EVERY single person with a turbod car here that wasnt turboed factory has had some problem or another.

maybe you should do some more research.
1) ok, you dont have the same intercooler piping, which is the easiest part of the install, but instead you get to remove your A/C and attach the supercharger to the side of your block via pulleys.
2) uh, with the WOMP i belive you get the OBX header, yes?
3) can you use the stock intake with the WOMP? no it comes with an intake as well... anyways, the intake is like two fucking parts, a filter, with the MAF in the middle :rolleyes:
4) the WOMP doesnt need fuel management? last time i checked it came with a haltech, no? and a fuel pressure regulator if not the haltech...
5) the WOMP has almost the same amount of pipes that a friggin turbo has.
6) the womp you have to replace your fan as well as removing the A/C, which you dont have to do with a turbo.
7) good idea to name intake twice to make it seem more complicated. good thing i have a good attention span and caught that :rolleyes:
i suggest you go to protegegarage and read up on the womp kit that you advertise in your sig but dont know shit about, noob.
agreed oh having problems.....but only if you dont maintain turbo properly, or any kind of F/I. Agreed with JCell on upping the boost on stock parts, which is pretty retarded because people already know the following consequences and they still do it in hope that their particular motor is factory beast, heh. Yea, there's a risk of having lots of problems, but that doesnt mean that you will have any. Just because people had/have problems it doesnt mean that someone else in line will have same problems. My personal opinion on superchargers....its a constant load on the engine unlike turbo....which MIGHT lead to problems that will occur sooner than with turbo, unless its taken care of at a proper time.
What I dont understand is, that most of people that I see with turbo'ed cars, are thinking or already went back to stock.......any particular reason? a thought of being scared of having a bit too much boost on stock internals and then go back to stock? if thats the case, why boost more than safe amount? There's a reason why msp (stock motor) is boosted at 7psi and not more. (friday)

Go with a turbo or a SC.
You can get more proven power for the Protege out of a turbo. You can run 8 psi on the stock engine. If you want some serious power, you can just upgrade your engine and turn up the boost.

Yeah, you have to take the weather where you live into concideration. I highly doubt that there is a non shop sponsored Protege that is SOLELY a project car. Our cars are daily drivers first and fun cars second.
You won't be disappointed with a reasonable ammount of boost on your engine. The Protege is such a better car with boost. Seriously.

I absolutely can't wait to see the threads you start after your turbo is done about problems. You live in a fantasy world if you think you are going to piece together a kit and have it work perfectly from day one. Get a clue. Why are people going back to stock? We have been telling you why, because of the problems that you refuse to believe will happen. Hate to burst your bubble, but what size turbo do you plan to run? More then likely it is larger then a T25, which means even if you run lower boost then 7 it will still be harder on the engine then a stock MSP setup. Sounds like you have lots more research to do before you install anything on your car.

It doesn't get as cold here in TN as it does in other parts of the country. The problem I had to deal with over the winter was warming up the car. It's not as simple as just letting the car run for a minute before you drive since it is so cold outside. Then I was always worried about the duration of time when it was warming up that I would be hitting boost. Not to mention the fact that the Protege5 ecu already acts odd on startup because of the VTCS difference.

All my research is done, and been confirmed by Kooldino who's working with me on my project. Ill be running exactly same setup as Kooldino was running when he had FPR setup, AND he says he had NO problems with it whatsoever, until he started modifying the internals. Just because you ran into the problems it doesnt mean that I will. Get off my case

Matthew, dont get me wrong man (bowdown) I would love to get a wrx or even an STi, but I wanna have something different than half of people on the streets. I see more STi's in my area than Protege's. Why am I going with boost? or doing any kind of mods? I guess its a family habbit....modding is a hobby for me, as Im spending half of the time in a my dad's garage, but thats not the point, heh. You are definetly correct on the idea of investment of the turbo, which you could of put into a downpayment for something nicer. I know that Protege is not the best in the world, but I still like it, heh.

Well, 250 to 325 wheel HP Proteges will run with and beat A TON of really good cars, many STi and EVOs included.
Yeah, it means a built engine and some good boost, but it doesn't cost as much as you may think, IF YOU DO IT RIGHT THE FIRST TIME.

indeed. Take a look at Kooldino's mp3t. yesterday (Sunday) we just finished the placement of extra 4 injectors and tunned it somewhat for wide open throttle at 14 psi. Shits fast as hell! Beating STi's is easy from a roll, like taking a candy from a baby. Last year Kooldino dyno'ed 250 at the wheels with a fuel cut. Now he should have more than that, since we're gonna tune it at 18 psi next weekend. With his car it was alot of test and trial, like he cracked a FORGED CP PISTON 9.1:1 ratio. Thats when he ran 13.8 at the track last year. Then we rebuilt the motor with 8.5:1 comp. ratio CP pistons, and now that monster is back on the road. I wish everything would be done right from 1st time, but thats just not the case....otherwise everyone would be perfect and there wouldnt be any crimes, hehe (exhadurating) but other than that, to avoid problems (if you know what you're doing) just keep maintaining the vehicle as it should be maintained.

I figured it's not worth arguing over. I still much rather have the supercharger over turbo anyday.
After seeing it, you might change your mind... but until then... it's a worthless fight.
correct me if im wrong, but isnt supercharger always on? Doesnt it make constant load on the motor at any given time/rpm? If thats the case, I still rather have turbo than S/C

turbos work with exhaust gases, the exhaust gases move the turbine insise the turbo, but turbos have some lag point. on the other hand, S/c are belt driven, that means that the compressor inside the s/c are belt driven such as an alternator, etc.
hope this helps

Here is a Supercharger on a Mazda Miata. What a Supercharger does is
very similar to a Turbo, however, how that air is forced is very diferent.
Each has it drawbacks and advantages.

http://www.wickedmotorworks.com/uploads/parts/1034056270_Image1_supercharger.jpg
The supercharger is often much easier to install, there are fewer problems because the system has nothing to do with the exhaust, there is no problem with boost control because it’s as simple as changing to a larger or smaller drive pulley. However, a supercharger is driven by the belts and for it to function; it robs the engine of power just like power steering or an alternator. Luckily the Supercharger usually makes a lot more power than what is required to drive it. If the engine makes 100 more Hp and it only takes 30 Hp to drive the supercharger, the engine is 70 Hp Stronger. This is why many chose turbo over Supercharger and is it's only real negative.
You still have to build the engine to handle the total boost but get a bit less HP than the turbo running at the same boost due to the driveline loss.
The supercharger comes in several forms and sizes just like a turbo.
Some setups look like a turbo and even allow the use of an Intercooler to increase performance and reliability.
Most are bolted directly to the intake manifold or even replace the entire intake manifold.
The Supercharger is instant power and is creating boost all the time. However because it's linked directly to the RPM of the engine by a belt, the amount of boost it adds is directly related to the speed of the engine. So at 3000 RPM you would get 5 PSI of boost, At 6000 RPM you would get 10 Psi.
I have only ever seen one on a Protégé. Superchargers are much more popular with Mustangs, American Muscle Cars and other large displacement cars.

it uses the exhaust gases to move the turbine so it compresses fresh air, then that compressed air goes to the intercooler (if equipped) and finally goes into the intake

I think is better to keep the induction like it came from the factory. i.e. keep proteges N/A as they weren't designed to handle forced induction as well as a car that came with a turbo/sc from the assembly line.
just my 2 cents

Lot of misconceptions and crappy information in this thread. Ken and Brian have made about the best posts... Yes a turbo does "recycle" exhaust gases.. it pulls it's energy from the exhaust gases, both from the velocity and from a thermal energy change that yields the energy that rotates the turbo. it actually results in an overall increase in efficiency of the motor... the restriction that the turbo creates is less than the improvement it makes on the intake side... you can't get energy for free though, and that is where the excess heat and velocity changes come into play. So from that standpoint it is exactly that.. recycling/re-using the exhaust gases..
Now as far as belt driven turbo... that's exactly what the WOMP is... a belt/shaft driven turbo. It's not a roots blower last I had heard... it is instead what is referred to as a "centrifugal" supercharger which is another way to say "really big turbo compressor wheel driven by a belt/shaft" (If the WOMP blower has changed again/I have it wrong, please let me know so I can correct the wording)
Also... the turbo "lag" that people complain about is only due to improperly sized turbos typically. There is some boost build up time as you get into very large pressure levels, but there are a lot of ways to get around that and it largely comes down to sizing and design. Keep in mind supercharger "lag" is far far far worse... superchargers build their boost exponentially relative to RPM. So if you are running a kit at 10 psi you have 10 psi at redline... but it falls off exponentially as you go down in rpm's... so at 2 or 3000 rpm's you have nearly nothign for boost.. whereas a proper turbo can give you 5 or more psi in many many cases. (my 16G for example).
Lastly... as far as problems and maintenance... I disagree... I lost a motor because the car was a test bed before I owned it and had the living crap beat out of it and ridiculous boost put through it. But even then, and now with the full out setup I have, I have yet to have had any leaks, any heating or cooling issues, or any running/driveability issues. It all comes down to doing things right and knowing what you are doing. If you aren't well versed in cars and mechanics... then don't go custom anything... even custom N/A. You'll have problems. If you know what you are doing... then you'll be good to go and turbo, super, N/A will all be depending on what you want, who you want to deal with, and what's available to fit your needs.

there are only a couple of things to worry about.. first of all "lower compression" is NOT a necessity.. I intentionally kept my compression high when I did my motor.. I run 8.9:1... so ignore the comments about that... you don't HAVE to lower your compression...
As far as problems of making an NA car turbo.... there aren't really any. Our motors are only made to withstand a certain amount of power... if you got there by some means NA you'd pop the motor just the same... turbo is just easier to achieve it...
The only actual two things you need to worry about with a turbo on an NA car is making sure you can provide it with fuel proplery and monitor it. Outside of that little else matters. Timing adjustment is important when you get into higher boost/power, but before that... not a big deal.

As far as problems of making an NA car turbo.... there aren't really any. Our motors are only made to withstand a certain amount of power... if you got there by some means NA you'd pop the motor just the same... turbo is just easier to achieve it...
The only actual two things you need to worry about with a turbo on an NA car is making sure you can provide it with fuel proplery and monitor it. Outside of that little else matters. Timing adjustment is important when you get into higher boost/power, but before that... not a big deal.
Good point TurfBurn. lower compression pistons is not nessesary unless you're going with alot of boost (like Kooldino and few others here)
Agreed on the problem issue......as long as you maintain and dont go boost happy turning up the knob on the boost controller, its gonna be fine
Yes, definetly controlling the AFR is a major thing in tunning, and thats where wbo2 comes in. MPi or Haltec is good to have, but when running 6-8 psi, you dont really need it as long as FPR/FMU gives the correct fuel pressure.

I'm going to be running over 20 psi of boost.. and I'll do it on pump gas with 8.9:1 pistons... so we'll see.. i'm already running 13 psi without issue and running more timing than anyone else on the forum... so I'm working to prove just how feasible high comp is with high boost. I'm working on one more little project right now before I start pushing that more.. then once I get the transmission taken care of.. THEN we'll really go boost happy. I'm basically working to put in as much boost and timing as I can that the motor can take, the turbo can create and run AFR's around 12-12.3.
shit man! More power to you! 8.9:1 comp pistons can handle alot.....not as much as 8.5:1 pistons though, hehe. Let us know how it goes! Im really tempted to hear

I only have one secret... JandS Safeguard :) That and I am moutning a micorphone to the block so I can listen with noise canceling headphones to also confirm on my own as to what is happening inside those cylinders. I'm determined to try and set the bar in at least a few places for most power at psi's ;). Again... one good thing about turbo... you need more power? If you have the support mods, you just turn up the boost.
