Pontiac fiero manual trans questions

[v8Fiero]

I have a sbc in my 87 pontiac fiero bolted to a stock 5-speed. fieros dont have many options for tranny choice, this one is the strongest manual that can be bolted up transversly (sideways) in a fiero, otherwise there is one auto that is slightly stronger but I prefer the 5-speed. I have already done a few things to it to help hold the power but Im just wondering if you guys have any other tricks or advice for making a manual trans stronger.

I have already cryo treated all of the internals, Im planning on taking it apart again this winter and shaving half the brass teeth off the syncro blocks (in 2nd, 3rd and 4th gear) for easier up-shifting, does anybody have experiance with doing this? any advice is appreciated.

has anybody ever heard of "Cryo-REM"? here is a website for referance:

Im familiar with cryo treating and its benefits but is the REM this website offers worth it? I am planning on changing motors out this winter to (old one was low-rpm torque) a higher rpm powerband to try and save this tranny from whiplash on launch, would this REM process help with shifting in the 7000rpm range? thanks in advance.

I can't believe the thing even fit in there...wow. :shock: The bodies on those are plastic aren't they? Sounds like a cool car. like to see some pics. :D

lol, thanks, it was an extremely tight fit, I have pics in general section of this forum in the thread "newb to the forum". it is all plastic body, race weight is just over 2500lbs... after I got done with the hack saw. :D

I think your weakest link in your transaxle would be the axles and CV assemblies themselves. A "soft" stock type diaphram clutch pressure plate will save allot broken parts in your drive line if your thinking of putting big power to a set up not designed to handle much torque, trick I learned hot rodding VW's with inheritly weak stock transaxles which were designed to handle about 60 Hp. I could side step the clutch @ 6000 rpm and speed shift any gear on my souped up 69 VW and it would slip just enough to absorb allot of the intial shock and the stocker would live, if I went to a higher pressure performance pressure plate and or rigid disc, It would self destruct quicker than a cat could lick its azz, just a thought.
Goodluck ><Cp

^ thanks for that advice, I already have a spec III in it the car that already blew up my old tranny, I was hoping that with all this work done to the new tranny the CV axles would be the weak link since they are a dime a dozen and can be changed out in 30mins at the track... but thats just "hoping" not an actual proven fact, so I need as much give as I can get. does anybody know if I can use a differant weaker pressure plate with the spec III clutch disk? or would this just not work with their clutch material? thanks

If the clutch disc matches up, I dont see why you could'nt use the stock type pressure plate with a agressive high friction rigid disc.
