1988 Fiero track car
Posted: Mon Jun 07, 2021 2:18 pm
Background: I've been doing Time Trials in sport class with a lightly modded 2009 Corvette Z06 for a couple years and I'm getting bored of it. Not the racing, that's always fun, but the car. I want to build something different and interesting. The end goal is to have something around as fast as the corvette, but lighter and simpler (but not cheaper, let's be realistic here).
To that end, I've picked up a 1988 Fiero base 4cyl car. No power anything, no sunroof, perfect starting point. The current plan is to build up phase one over the course of the next year or so and go from there.

Now, the plan:
Drivetrain:
- K20A2 swap - This will give me a nice light compact engine and transmission which are known to be able to make very good power (~200whp NA for the first iteration, ~400whp on a supercharger once the chassis development is more or less done). I have a set of mounts from kfiero on their way: https://www.facebook.com/groups/1086771178323278
- I'll be using the stock RSX-S 6 speed transaxle, adding an LSD
- Custom axles - Honda inner and Fiero outer
- RSX shifter and shift cables are actually around the right length for the car, so use that or an aftermarket RSX shifter like KTuned
- Halltech ECU
Suspension:
- Tubular upper and lower control arms in the front, and links in the rear. Sphericals everywhere.
- Not finalized on coilovers yet, working off Steven's development but I may look at working with a racing coilover manufacturer like Reinharte to develop something for the Fiero, or make something from QA1 work.
Brakes:
- I like WCF's kit to put the Porsche 4 pot Brembos with 2 piece rotors on all 4 corners. Light, race proven, easy to find racing pads.
Interior:
- Building to Max category Time Trials rules
- Roll cage
- Stripped except for dashboard
- Fixed racing buckets (not finalized on brand/model yet)
- AEM or Haltech digital gauge cluster (remove stock gauges completely to simplify engine swap wiring)
I'll try to update as I go, right now I'm just collecting parts, the first step will be the engine going into the car as the old duke is pretty tired. That's not gonna keep me from making it go around the local race track as a baseline though!
