MP3 Header

[trobbins]

I saw on Corksport.com they have a Mazdaspeed stainless header for the protege 1.8 and/or 2.0.

Does anyone know if this will fit our cars??

Its $739USD

[StuttersC]

The 2.0 liter one will fit but I thought it wasn't street legal because it removes the cat that's right off the exhaust manifold. The Mazda Motorsports header is supposed to be a more conventional 4-2-1 header design for the World Challenge Protege cars. (Read as off-road use only)

[APEXistud]

Hell, if you're willing to take the chance, go for it. My only concern would be the ECU and noise. Removing a cat will unleash a lot of noise. And by removing a cat, I'm pretty sure you kick on the CEL.

[freekwonder]

it will trigger the CEL. i had a 4-2-1 header on my zx2, no resinator. 2 1/4 pipe, and a dragun fire muffler. since i didnt have a cat my CEL came on and my car was LOUD. people had no problem knowing when i was around.
but if you live in a area that doesnt have smog you can always get a performance cat and get it welded into the downpipe. dont know if it would smog but you would be visual inspection passed. thats what MO does.

[Brian]

well as far as finding parts for our car it is hard .. but i will let you in on a secret we have the same engine as a ford Probe SE 2.0 ,,, i Currently have a exaust system off of a 93 Ford Probe on my Car with minor mods.. you have to have a extra o2 sensor bolt weilded into it and some flange work done to the ford cat .. 2 different size flages,, your check engin light will come on in a day or 2 .. because the o2 sensers not being before and after the first and forgoten cat.. oh and its not that loud i pomise .. shoot me a e-mail if you want more details ..

[big_ben]

Brian,
If this is true about the engines being the same, will other parts from the probe engine fit ours too. Such as CAI, pulleys, cams, etc.? Let me know.

Ben

[MazdaMP]

same engine as what year ford?
thanks

[OceanPark]

Probe SE 2.0 and the exactly the same our engine, they are similar though.

[NCMP3]

No kidding? a ford probe huh? Yeah drop us a line on that shit we will all be very interested. Thanx :cool:

[Brian]

they but the 2.0L in the Ford Probe 90-97.. SE .. our cars already have the Mazda J-Spec exaust cam .. we can order the J-Spec intake cam for from (part# FSH9-12-420) C CAMSHAFT, INTAKE PROTEGE 2.0 FS, 1.8 FS 1998-01, 1999-01 $167.10

Notes: Used in place of stock intake cam, this intake cam from the Japanese Sport 20 will add 12 hp to your FS engine. Not smog legal. .... this is the add from www.mazdamotorsports.com (http://www.mazdamotorsports.com) .... you will want to search by engin type and if you dont know .. that will be the 2.0 dohc I-4 .. and a full list of parts for our engings will be shown .. from lighend flywheel .. oh and i was wrong earlyer .. the us enging code is FS .. the J-Spec is FSZE

[Brian]

oh and by the way .. come on now have have been giving so good info .. except my tubo project .. sombody rate me ...lol :D

[MP3Ben]

Are you serious that we already use the j-Spec exhaust cam?? And I was about to order it too...hehe I'll rate you if you can give me a definite answer... :eek:

[StuttersC]

The FSD motor in the MP3 was the same as the 2.0 liter in the ES model, which means it has the stock cams as any other Protege 2.0 liter.

If Brian is right then that would mean that every 2.0 liter (Protege 5 and ES and LX 2.0) have the J-spec exhaust cam??

The exhaust cam on the FS-ZE motor was supposed to be special, from Mazdaspeed I thought. I forget though

[Brian]

Ben i was trying to find the were i had read that we had the j-spec exaust cam, but im not sure. I know thats one of the hot topic at the Probe sites because they want our exaust cam but it dose not have a distibutor gear on it so they cant use it enless they scrap the stock ignition system

[MP3Ben]

Thanks for the info Brian...I checked out the Probe forum and learned a heckuva lot, but wasn't able to find the post on the exhaust cam (I'll do a more detailed search later).

I believe the stock exhaust cam for our car is either the J-Spec from the FS-ZE (still trying to determine, with Brian's help) or it's just stock Protege...

Chris, I think the FS-ZE exhaust cam isn't made my Mazdaspeed...my reasoning behind this is because I've checked both the Corksport site and the Mazda Motorsports site...at MM they sell the exhaust cam from the FS-ZE, while at Corksport they sell both that cam and a Mazdaspeed exhaust cam.

I would assume that the parts are not the same in that case...unless Mazdaspeed made the FS-ZE cam AND did another more aggressive version to sell as aftermarket on their own... :cool: I'd like that! But I doubt it, IMO.

[StuttersC]

Your right, I think the Mazdaspeed exhaust cam is from the "Sport 20" which uses the FS-ZE, but the cam from Mazdaspeed isn't used in all FS-ZE specifically...I dont' know what I was thinking. But, if the FS-ZE exhaust cam is a stock 2.0 liter part, then the intake cam would be a nice fit and would be one less part you would need to change the MP3 motor over to FS-ZE specs.

I thought Mazda Motorsports had the intake cam and an un-ground cam you can buy. The intake cam is from the FS-ZE motor.

[jayrcr]

if any of you ever crawl under your car you might find out ther is another cat under there besides the one on the header!

[StuttersC]

jayrcr:

Your talking about that larger section of round tube right? I thought that was just a pre-silencer, not a cat...The pictures I've seen of after-market cat-back systems remove that section, so it shouldn't be a cat...

[jayrcr]

its acat alright the muffler shop poped it off for me one day very restrictive.

[NC_MP3]

You see the 2 wires going into that big round tube? 1 is visible from the engine bay, other from under the car. They are O2 sensors hehe, silencers don't have O2 sensors :)

[jayrcr]

hehe not all cars with two cats have 2 02 sensoers just cause we have OBD2 on the cars. drive down we will put it on my lift at my shop.by the way do see a egr valve on the car.if not check your muffler bearing :p

[MP3-Owner]

Our cars have two cats and a resonator. The first cat is right at the header and the second cat is about 1ft. or so behind the first cat. The resonator is the long tube behind the second cat. I had the resonator removed as well. It makes the exuast a little louder but it's not that bad.

[jayrcr]

try telling that to NC MP3. hehe :rolleyes:

[NC_MP3]

huh?

[MalkavianMP3]

I have a bit of a logic question for you guys. Why, if our motor is the same 2.0L as the protege5 and protege es and lx, do we haveand extra 10hp at the flywheel? I know that the exhaust system is different. but the extra cat would basically void out that hp. So where did the extra power come from, could it be that we actually have the J-spec exhaust cam or not? Just something to think about.

[MP3-Owner]

They also tuned the ECU. So who knows, but I know one thing for sure...There IS alot of power this car is holding back. We just have to unleash it.
The cats can go, that stupid, restrictive header can go, and with a few more mods this car has great potential if you ask me. :D

[APEXistud]

The extra HP came from the Dual Stage intake manifold, exhaust cam, and more aggresive ECU timing. Those are the only things I know of that give us the extra. From my opinion, the only way we're really gonna unleash the extra ponies is by an aftermarket header. Removing the cat from the factory header will probably to some good, but I won't do that. I'd rather replace the whole thing. ;) Just my .02 Cents

[big_ben]

It is most definately the exhaust manifold that's holding back most of the engine's power. If you go to the Racing Beat home page they talk about this in a little more detail there. They say that they couldn't fix this in the time that Mazda allowed for them to tune it. So as for me, I'm saving up for when an aftermarket header comes out that doesn't cost $739. That's way too much. But be patient, it will come. Has anyone looked under the car to see if all the pipes are mandrel bent or crush bent? If crush bent, you could replace all the pipes with mandrel bent when you get a header and it will drasticaly increase the power even more.

[Snomongoose]

I just wanted to put my 2 cents here.

The motor code on the MP3 and the P5 is FS-DE not the j-spec FS-ZE.

The exhaust cam on both cars are the same, the intake runners are different on the two cars. The ECU has been reprogrammed by Mazda to give the extra power to the MP3.

The MP3 only has a muffler change by Racing Beat. That is why Racing Beat is coming out with cat back exhaust for the Protege Sedan and also the P5.

I do believe the exhaust is crush bent piping. Manderal bend piping would help all of us out.

The cams on Mazda Motorsports is going to give us an increase in power, but it is not stock on the MP3.

I have seen on either Corksport or Mazda Motorsports an uncut FS-ZE cam that has to ground down.

[MalkavianMP3]

The exhaust pipes are mandrel bent( has pictures of it). I need to post the photos butI would have pictures if it wasn't for that damn accident I had in august. :mad: I'll have the pics up soon and I'll send them in.

[APEXistud]

POP Quiz......Does anyone know what the DE on the FS-DE stands for...... :D Just wondering if anyone else knows. It carries the same meaning on the SR20DE & DET

[Snomongoose]

Don't know the actually meaning of DE, but I know that the compression on the FS-DE is 9.1 to 1 where the FS-ZE is 10.5 to 1.

Mike http://groups.yahoo.com/group/mazda_protege5

Got me on that one.

[mazdamp3_18]

i just wanted to post about the removing cats thing. removing your cats will only gain you 1-4 hp. i had a vw golf tdi and i put a straight pipe and dynoed it and i gained 10 hp and a crap load of torque. i then had the cat removed and i gained 1 hp. in my opionion that is a waste of time for 1 hp. now removing both may free up a little more than 1 hp but not much more.

ive also got a question about the intake cam. do i have to get a fuel management computer like apex or will the car run fine without any timing or fuel mods. also will it set off a cel. i know my car has been going crazy bc of the racing beat exhaust. mazda told me the computer was very sensitive to the change in exhaust flow.

[StuttersC]

All 2.0 liter Proteges have the FS-DE motor in it. The 1.8 liter I think is FP-DE. That's why the cams will work for the 1.8 liter and 2.0 liter. They have the same head.

But, for 2002 all Proteges are supposed to have the 2.0 liter.

[big_ben]

I have a question about the "unground cam". If you buy that, will there be instruction about to what specifications the machine shop will have to shave it to? Or will they just know what to do with it? And why don't they do this before selling it to you? :confused:

[Snomongoose]

Ben,

An unground cam is made so you can do what you want to it. Up to you and the machine shop.

Mike

[DooMer_MP3]

So are the intake cams on corksport (The FS-ZE ones) ready to be installed? Or do they have to be shaved? Seems stupid to sell them unshaved if they are J-Spec meant for the 2.0 liter....

[Snomongoose]

From my understanding yes they are ready to install.

Your best bet on those type of questions (ready to install and such) is to ask for Derek at Corksport. He is the man for questions on Proteges there.

Mike

[DooMer_MP3]

Cool thanks. I'll have to keep Derek in mind in the coming year when I start doing stuff. Again, thanks for the info!

DooMer_MP3

[Snomongoose]

Not a problem, alot of people from protegetech.com deal with Derek and say he can answer alot of the questions.

Mike

[dustobub]

Back to headers. I remember seeing that the bosal header for the probe/mx6 would fit our proteges. Would the same go for any header made for those cars such as the brospeed I saw on caraddonparts.com Thanks

Dustin

[StuttersC]

Dustobub:

Are you sure that header will fit? I didn't think the motors were that similar. Where did you here that from?

Just askin' becuase I'd like to know.

[dustobub]

There have been several posts about the bosal header for the mx6/probe/626 from mazda motorsports. The part number is the same for the bosal mx6 and probe header at bosal.com. I have read that with slight modification the bosal will fit so that leads me to believe that other headers for those cars could fit ours. Thanks
