[bill harvey]

In your MSP did they make a worthwhile difference? what other mods have you done? I am looking at building for road corse work and street driving with stock redline.

very cool..i wonder what the specs are?

 

[SmoothCriminal]

stock cams are pretty much the best in the way of FI, dont really want anything with a longer duration

When i had my subaru we found that cams helped quite a bit the overlap isn't that extreme that you are going to loose boost.

Yea in my AE86 and my GC8 cam upgrades was the most bang for the buck. But those are NA cars so im not to sure about turbo'd cars. If someone has done this mod pls post I'm very interested. Also why would the intake cam only be avail?

the exhaust cam was discontinued. It was causing stalling/rough idle in cold weather in japan.

people, don't mix apples and oranges.
This guy is asking about cams in a Mazdaspeed, not Subaru's or NA cars.
IMO, I would not buy just the intake cam, since the exhaust cam is no longer available, and go through all the trouble of installation for just a 5 hp increase.
Installing cams in a Mazda is kinda hard. It is not like Hondas. I can swap cam in a Honda engine in 30 minutes because it is not necessary to remove the timing belt or cover.

 

[bill harvey]

both cams are still available from certain places.

You can get the j-spec intake cam (FSH9 casting #) from srmotorsports.com that they are calling a "Mazdaspeed" cam (which doesnt exist, its a j-spec out of the FS-ZE) , where i got mine. You can also get what they are calling a "Mazdaspeed" exhaust cam. All the information i have found on the "Mazdaspeed" exhaust cam points to it being one thing, a repinned intake cam 180* with the casting numbers ground off of it. Whether its a J-Spec intake cam or a factory intake cam i dont know.

All the specs are right here:
The stock intake cam - Lift- .344 Duration- 198* @.050
The stock exhaust cam - Lift- .323 Duration- 200* @ .050

"Mazdaspeed" Intake cam from srmotorsports:
The J-Spec cam (FSH9) which i installed is - Lift- .344 Duration- 210* @.050

"Mazdaspeed" exhaust from srmotorsports:
If its the stock intake repinned- Lift .344 Duration- 198* @.050
If its a J-Spec intake repinned - Lift .344 Duration- 210* @.050

ALOT OF THIS INFORMATION CAME FROM THEMANS FAQ (and other threads) WHICH CAN BE READ HERE - TheMans PROTEGE FAQ PAGE

EDIT- Corksport at one time was mentioning that they were going to be doing either copies of the "Mazdaspeed" exhaust cam, or custom grind exhaust cams, they still have the J-Spec intake as far as i know.
ALSO WHEN I MENTION MAZDASPEED IN THIS POST I AM NOT TALKING ABOUT THE CAMS IN THE MAZDASPEED PROTEGE. ALTHOUGH THESE CAMS WILL FIT IN THE 2.0L MAZDASPEED PROTEGE THEY DO NOT COME IN THESE CARS. MAZDASPEED IS A BRAND.
