Hello everyone. My name is Greg. I’ve been around Fiero’s since they were new on the street.
My dad purchased a 1984 2M4 manual then when I was 16 I had the chance to buy a 1986 SE manual V6 from a family friend for a good price I jumped on it. My friend like it so he found and purchased a 1987 GT auto.
Now a few years ago my dad sold his trusty ’84 and picked up a very clean ’88 GT manual.
I’ve been into racing the late model 3800 Grand Prix’s. The quickest I’ve went is 11.24 using the M90 supercharger. That car saw its last track appearance last summer when something in the transmission broke on the starting line, and the demod began.
That is about enough with the history and on to why this thread exists.
Purchased a rolling 1987 GT shell. The current plan is to drop in our Grand Prix power plant that dynoed at 400hp to the wheels.
The engine is a 100K mile plus short block, Intense Racing Stage 3 heads and stage 3 camshaft. Stock Gen 5 supercharger with the inlet bored out to 80mm to match the BBK 80mm LS1 throttle body. ZZP Stage 3 Gen 5 intercooler. LS6 MAF sensor. ATI overdrive balancer and many supercharger pullies. Currently it has a 2.6” pulley and is pushing about 16 psi on a good day with C16 race fuel.
The Transmission is fully built. It has a ZZP input and output shafts and all other internal upgrades. 3.29 gear ratio with GMR Torsen differential. The trans is currently with Tim King getting a refresh so it can take more abuse.
Transmission control will be handled by the Powertrain Control Solutions TCM-2000. We will also incorporate the GSM-5000 push button shifter and add the paddle shifter on the steering wheel for added fun. The TCM-2000 makes tuning a breeze since the adjustments are done in real time instead of the OEM PCM which to flash you would need to stop and make your adjustments.
The Gear Shift Module (GSM) is a nice touch because it is a push button shifter and will fit nicely into the stock manual console cover we have. This also reduce the work involved is getting shifter cables installed and to function correctly.
I’m still gathering parts but as of right now I am stripping the stock Fiero engine harness. I have already stripped and separated the 3800 harness, and need to order the PCS harness.
Once it warms back up some or I make some room in the garage I will pull the engine cradle out and do some mock up for engine and transmission mounts.
Here is the '87 as it sits
The disassembly of the 3800 engine harness
Pictures will follow as I get them.
Thanks for reading,
