88 w/I4 OK for 3800 swap? (Page 1/2)
Todd00000 NOV 12, 01:11 PM
I've found a high mile 88 for cheap it has the I-4 w/auto. I want to swap the SC3800 w/4 speed automatic.
Since I want to do this swap is there any reason to avoid this car?

Thank you. Now comes the "is it worth it?" debate. It has 289,000 miles.
1. The swap cost and associated rear end rebuild are a given no matter the car.
2. The interior looks surprisingly good in the pictures and should only cost a little more to get nice than what I was planning to do on any Fiero.

3. It needs a paint job and the base wheels will be replaced.
4. Headlights overhauled.
5. Front suspension rebuilt.
6. Needs new struts.
7. Needs brakes rebuilt.
What else does a high mileage Fiero need?

88 front wheel bearings will not hold up if you race the car. They will be fine for normal driving. Watch out for rust.

Where should I inspect for rust?

Jack up rear of car. Use jack stands. Remove both rear wheels. Next remove the wheel house liners. Several small hex screws and a couple of fasteners hold them in place. Look up at the frame rails and examine if they are solid or rusted. If they are rusted then the frame is toast. The car is basically scrap.

Is there an easy place to look when the car is at a dealer?

That does help. Thank you.

Pull back the trunk carpet on both sides of the trunk. The "short" sides. Look between the top, where the rubber seal is, and the little shelf that is on each side.
The cleaner that "side wall" is, the better. Look out for big holes and/or metal just rotted away.





Rust can appear in other places, but if it's anywhere, it will usually be in one of these places. Either side. No real rhyme or reason as to left or right.
Also check the floor pans from underneath. Especially around the tin plugs at the rear of the floor.
Look at the rear subframe (cradle) and the front suspension. A bit of surface rust is to be expected, but no rot or holes.
The less rust on the fasteners, the easier they will be to remove, to replace stuff. (Duh.)

Edit - If there is no rust, and no collision damage, everything else can be unbolted and replaced. Everything.
The space frame itself is essentially the same as a GT or Formula. The body panels can even be swapped around between all of them.

Have fun!
