These are some pictures of a resto-mod I did on a 1988 Fiero. Click any image for a full-size version.
The interior was more comfortable and didn't smell like mice, the brakes and suspension were safe, and the car was lowered an inch and a half.
I forget why there were holes in the water jacket here, but they needed to be plugged.
The engine was a Series 3 3800 while the donor car (PCM, injectors, fuel rail, throttle body, and such) was a Series 2. So, the throttle body needed some adapting.
I modified the thermostat housing from the original engine to fit the new one. The Fiero cooling system is a little unusual: the thermostat housing is the highest point, so it's important that it have a cap for filling.
I significantly re-arranged the accessory drive as part of the swap, so I made a custom alternator bracket.
The Fiero didn't have air conditioning, so I put an idler pulley at an appropriate place in the accessory drive.
I removed the lower trunk section to make room for the new exhaust.
The alternator also took a little room from the trunk.
I did get all of the gauges in the original instrument cluster adapted and working with the 3800 Series 2 PCM, but I also wanted a couple of extra gauges: a wide-band oxygen sensor for tuning and an OBD2 scanner for diagnostics and tuning.
I put the OBD2 connector and wide-band oxygen sensor output in the passenger footwell, along with a power jack — this made tuning more convenient.
A simple adapter allowed the Fiero speedometer and odometer to work with the Series 2 3800 PCM output.
I set up the entire engine harness to feed through one big connector. This made it easy to drop the cradle later when necessary.
After a number of fun years, it was time to sell the Fiero.
