Hey Turbo Techies ... A question.

I plan on travelling the N/A route for now, until a reliable turbo kit is produced for automatic P5's. My questions is thus:

Would N/A mods such as FS-ZE intake cam, MSpeed exhaust cam, beefy underdrive pullies, AWR header, etc have an adverse affect on a turbo kit ? Meaning, would I have to remove any of those mods in order to keep the turbo in good health ?

(P.S. I'm willing to take the hit on the wallet from going N/A then switching to turbo. I foresee that the car will remain N/A for several years, and I consider the $ loss minimal compared to the fun I'll have zooming around during that time :D)

Thanks for the input!

yeah, like he said, the header will be usless, but everything else should be ok....just stay away from high compression.

I would consider swaping the auto for manual. If you are going the performance route you are going to need the 5 speed! Auto's have too much lag, and not as strong! You'll be fine with everything but the header! :D

Just my opinion.

well there are alot of differences between running N/A and running F/I.
there are many threads that cover this already if you do a search under cams.
but the header canot be used or REUSED to make it compatible to a turbo manifold.
like i have always said if you are going to spend the mods on something like N/A for a protege it will end up getting you 30hp and a lot of money spent for it.
really man do it right go turbo and youll never regret it. the majority of the stock components you will end up keeping and have far more performance than N/A
 
would he net more performance gains from those mods without the turbo...or will it help the turbo and see larger gains once it is in

with the N/A mods you will never come close to the performance a simple 6-8 psi unit will provide.
with the right TURBO cams ( high lift NOT duration) you will also get better performance
 
Ideal cams for a turbo will be different from the ideal cams for a N/A car. The same goes for exhaust systems, actually.

If you use an underdrive pulley on the crank, replacing the stock harmonic balancer, remove it before you turbocharge the car. The link between destroyed engines, turbochargers and missing harmonic balancers have been well documented on the BP series Mazda engines. Oil pump failure occurs within several hundred miles. Mazda put a harmonic balancer on the car for good reason.

very good point kieth about the harmonic balancer ;)
 
The shop I deal with "RPMNYC" has found that certain underdrive pulleys are not balanced correctly. Causing them to build motors for customers who had installed them. Good thing I didnt use them on my honda back in the day!!! :D
 
Thanks for all the input, guys :)

So, the general concensus is ... (as it always has been) ... is to save and go turbo.

But ... there aren't any kits available for the sportronic P5 yet :( I want more zoom zoom now ! :D

andrew take a look at my car when we go to the meet and well talk about it there.
im sure i can come up with something and am in the process of working out with a shop to upgrade the auto trannys.
the problem is no one wants to warranty the work after the turbo so we'll see.
 
We sould have a car in here for an auto install in June or July. Then we'll have the kit available commercially.

Balancing of the pulleys is not the problem. It's the lack of a dampener (the proper term) that kills the pumps. The BP seems to be fine N/A, but the higher forces in turbo cars makes the dampener critical. Taking out a dampener is just a bad idea, although it can be easier to point the finger at a bad part instead of bad advice.

Just to reiterate ... Flying Protege has a turbo kit currently in R&D and will hopefully have it on the market late this summer ?
(2thumbs)

Woohoo!
 
It will be the same kit we sell for the manual transmission cars. We need to adapt the piping for the automatic setup, and we can't do that until someone comes by to have us install it. We've had several people interested but nobody's actually been able to come through yet. Until we get an auto car in-house, we can't do much...

Good point. But will our springs/rockers/lifters/etc handle a higher lift?

yes . were not talking about race cam specs.
a simple spring shim will help.;)
P.S. we dont have rockers sshhh:p
