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,
Greg

Project is starting to move along nicely now.
Ended up purchasing engine and transmission mounts/adapters from West Coast Fiero. That saved us at least a week trying to make our own.

We are in the process of wiring up the custom harness and adding the PCS harnesses also.

New steering wheel with PCS paddle shifters and digital display


Here is a picture of the paddles w/o the steering wheel


Aeromotive stealth pump kit added to tank


Close up picture of pump installed


First test fit of dirty engine. Looking to find places that needed trimming


Here is our new console plate fresh off of the CNC cutter


Picture of the above plate getting cut out

Here is what the shifter buttons will look like once installed

Coming along nicely. Good luck with the swap. IMO, the 3800SC is an excellent engine choice.
On the Automotive fuel pump I notice that it sits in the front of the tank that keeps it out of the area that has the baffles. If this is the case just keep an eye out for fuel starvation under hard acceleration or turns. It may work out fine but the baffles were put there for a reason.

The pump is actually the phantom kit.

It is designed for older tanks without baffles in them. We had to trim the filler tube and the vent tube inside the tank, but that shouldn't matter at all.
It should actually work very well in this tank.

radrace19....would love to chat with you in regards to the PCS setup...I think I would like to add that to my 328 replica.

I am about to drop the 3.4 Turbo that Jerry sold me a few months back into it and would like to add the paddle shifters.

Got the car started late on Sunday
Need to get some axles built and adjust the engine calibration some so it idles a little better.

Video will come soon.

that a lokar tranny dipstick?

Yes it is.
I used the Lokar TD-34L60EFM (stainless) or use the XTD-34L60EFM (Black).

While the transmission was out and still on the ground, I checked the fill level vs the stock dipstick and tube.
The level on the Lokar stick slightly lower than stock, so just fill to the top of marked area on the Lokar tube.

Well went to the track last night for the first time.
First easy pass it run a 12.19 @ 110

This is in all street trim and 3.0" supercharger pulley.

2nd pass it broke the drivers side axle shaft after launching at 2000 rpm compared to the 1200 rpm on the 1st pass. This was a parts store Fiero automatic axle.
The axle broke on the outside of the main shaft. My guess w/o pulling it apart yet is where the retainer clip snaps on the shaft.

Just a little update.
Our wrap job is almost complete.


Got the Holley EFI system all installed and, new DSS axles.

radrace19, what model Aeromotive Phantom fuel pump are you using with the 3800 and is it working well for you.

Used the Phantom 340 Stealth system. Part number 18688.

Yes it is working very well. When the engine combo was in our Grand Prix we were using an Aeromotive A1000 pump and this one is much quieter.

Thanks for the info Greg!
