Does anyone have any information about this cam yet? I know it's new, but I thought I'd try and see if anyone has any info about it's effectiveness before I order it.

Ambient

Dependent among other mods, 4-6HP increasing with other mods. Intake cam, I've heard anywhere from 12-20hp, once again dependent on other modifications. I have my exhaust cam waiting to be put on. To help cam installation you'll want to get your ECU reprogrammed. Corksport has told me that they have not had anyone put the exhaust cam on the US Protege and told them how it feels. Main thing I noticed with the intake cam was the idle feeling weird, which will be fixed once my exhaust cam is on.

If you want to wait until I get mine on, just let me know and I'll set up the appt. I've just been lazy.

Eric F

Thanks for the info. I think those HP numbers are a bit high, but let me know when you get the exhaust cam installed.

eeterp

Last time I checked, corksport hadn't received them yet. Jeremy Dehart told me that the mazdaspeed exhaust cam will add about 15hp to the fs-ze. Eric where did you get the weight spec on the mazdaspeed flywheel? Did you get that Email I sent you about the headers and pulleys?

Ambient

They have then ready...I ordered not too long ago.

The exhaust camshaft on Corksport comes stock on the FS-ZE engine, so it's not resgistered as a performance part. It just acts that way because we have a detuned version of the FS-ZE, the FL-03

Eric F

Huh??? Wayne, I think you may be misinformed. The only exhaust cam I've seen on Corksport is the MazdaSpeed cam. It doesn't come stock on the FS-ZE engine, it comes with a limited production, special edition, Sport 20 with the FS-ZE engine. Also, I believe our engine codes are FP-D for the 1.8L '99-'00, and FS-D for the 2.0L '01+. At least that's what it says in Mazda's factory service manual. The KL-03 is a US spec version of Mazda's V6 engine.
Jeremy, I got your email today. I wasn't at work yesterday, so I just replied today. Everything I've heard says the cams aren't in stock yet. I doubt the MazdaSpeed exhaust cam will add that much power. The special edition Sport 20 in Japan had the MazdaSpeed exhaust cam and pistons, and it only made about 5 more HP than the stock FS-ZE. It might add a little more HP with our engines, especially if combined with the FS-ZE intake cam and Bosal header.

Hrm maybe I was...I'll have to look into it...Maybe I was talking to BEN at corksport
I'll be sure to find out the truth about it and since I'll be installing it short, have a HOW-TO with good pictures.

Eric F

Jeremy, I forgot to mention, I usually call Mazda Motorsports for information. I get the feeling that Corksport goes through them for many of their parts, and much of their information. Why not go to the source? I also like that if Tim or Brian from Mazda Motorsports don't know something, they'll say so. They won't tell you something that's wrong. Besides, Mazda Motorsports prices are better on many of our parts also, even without being a racing team member.

The only thing I can thinkof is the fact that the 3rd gen 2.0 has the same engine as the 93-97 4cyl Probe. The manuals are pretty much identical. As with the Kia Sportage, same engine.

Eric F

There are a few differences in the '93+ Probe/MX-6/626 engines and the Protege engines. Most notablely the DIS ignition the Protege uses. Some of their parts won't fit the Protege, and vice versa. All 3rd gen Proteges have OBDII and DIS ignition, so the UR racing underdrive pulley for the MX-6/Probe won't work on the Protege. The MazdaSpeed exhaust cam probably won't have the gear to drive the Probe/MX-6's distributor.
The Kia Sportage has an FE3 engine, which is not the same as the FS. The bore spacing and deck height of the block are different. Most parts will not interchange between the FE3 and the FS engines. The FE3 block is almost the same as the '88-'92 2.2L Probe/MX-6/626 block, but with a newer DOHC head. That head would be a nice swap for the '88-'92 2.2L Probe/MX-6/626 guys come to think of it.

I called corksport to order the exhaust cam less than 2 weeks ago and they said they did not have them yet. Anyone else recieved one yet?
Eric is correct about the engines. The Kia Sportage engine is a 2.0 same block as the 86 626 and B2000 but with a DOHC head. I considered using that head/intake/harness in my B2200 but dont want to use Kia electronics=yuk! Still looking for a wrecked 626/MX-6 turbo to swap in tho Kia actually used several Mazda leftover engines in earlier models not sure if they are using any now though.

Eric F

Anyone have any updates on this exhaust cam yet? I'm still wondering if this is going to make enough difference to be worth the cost.

How long before the Bosal header hits the market and how much?
Or is this the header from CorkSport?

Eric F

The Bosal header has been available for a long time. It's not made specifically for the Protege, it's made for the Probe/MX-6/626 2.0L cars. It should work as well or better than the MazdaSpeed header for the Protege though. It's available from Mazda Motorsports for under $300, but it's been hard to find in stock recently.

I called corksport the other day and still no mazdaspeed exhaust cam. I called Mazda motorsports and they said they sell mazdaspeed parts and have no listing for a mazdaspeed cam. They do have the FSZE exhaust cam to go along with the intake cam and it is not the same exhaust cam that comes stock in a 3rd gen protege as someone previously said. I think the mazdaspeed cam should be a little better so im going to try to hold out for it.
