Hi folks,
I hope you are all keeping safe ? So to bother you all. I bought another Fiero from a scrap yard for parts. It turns out its an 88 model ( to far gone rust wise and has been moved around the yard by a forklift causing some panels to snap).
Could i ask what is interchangeable with my 86 ? By that I mean not having to drastically modify drilling holes finding obscure bolts etc.

Cheers

Most everything will interchange between years, with the exception of 88 suspension and brake parts. (88 carried a complete redesign.)
I should mention that the 88 (and 87) 4 cylinder engine is quite different from the 86 and earlier cars. The later engine can be swapped in, but you will have to swap in the entire computer and engine harness to make it work. (NOT a big deal, really.) The fuel line routing is also different. With that said, the swap is mostly bolt-in, assuming yours and the 88 have the same type of transaxle.

A nice handling upgrade can be achieved by swapping the 88 rear cradle and rear suspension into earlier cars, but it involves some fabrication and a good bit of trouble - probably more than you want to deal with, just now. If the car is badly rusted, those pieces might be too compromised, anyway.

The second generation headlight motors/controller is a nice upgrade also!

An 88 rear cradle swap is relatively easy and quite beneficial to handling, and opens the door for some brake upgrades as well.

Do you have fabrication skills or a machinist friend?

The car was scrapped back in 2009 and has sat in this yard since then the condition is well poor.
I am sofar cost wise down the line with my 86 GT and time spent on it . My skill set is only moderate at best !!
I read the post on the head light motor loom etc so Ill give that a go.

If the calipers are still there PLEASE save them and sell on the Forum or eBay. These are scarce and folks here will be glad to buy them.

I swapped in the 88 rear suspension on my 85 SE V6....the subframe bolts up with no mods, but the coolant hose on the left side needs some adapting. Also, you must convert to coilovers because the struts are angled farther in and there is no room for the stock large diameter springs. The engine mount is also different (Just get the FS solid rubber 88 mount)

I included the rear 88 VENTED disc brakes in that swap......Then later swapped in 88 front calipers w/ 12" C4 Vette discs (Requires a bracket to adapt the caliper to the 85-87 spindle plus the hub must have the old disc removed)

Much better ride and handling (basically eliminates the bump-steer problem).

I second the headlight motor swap; Much smoother and quieter, and less likely to catch on fire (And replacement motors are still available)

What he said

Swap in the rear suspension from the '88 and upgrade the front brakes to match. (Edit: I planned on doing that on my last '87, I'm sure I still have the paper pattern I printed of where to drill/cut.) Especialy if you fancy tracknights at Forrestburn, which you should, since you can probably see it from Harthill. It's beside the transmitters.
Coilovers are dead easy, I've done a few, either on the standard struts (cheap), or full Bilsteins (no change out of £400). '88 front bearings are a weak point so best to stick with the '84-'87 front, the carriage to Scotland is more than the bearings.
I'll swap you a set of redrilled Corvette 12" rotors, for your front bearings. You'll get the front conversion brackets in the Mall, Sluppy123, I think?
I can also rebuild your '88 calipers and a few other things.

If the rear subframe needs welded, or you want it reinforced, I can do that in exchange for a few bottles of Fraoch, or Skye Red.

I can upload images now??

Cool, I should update my build thread now!
