Time to make the change from 2.8 to 3800.  Hope this goes well.

It fits and I am working on connecting everything. Had to use the factory exhaust and modify the crossover pipe to fit the shift linkage. Also using a spintec muffler that we had to modify to work. Biggest item is how to male the throttle cable work.
Thanks

I tried to post a video of the motor running but it won't let me.

Quick question, is that all there is to removing the Fiero engine cradle? Just the two front points, the 2 rear points, the 6 strut tower bolts and the engine wiring harness? I mean I understand there's hoses and fuel lines to disconnect, but I never thought it was that simple (I'm going to be doing an engine swap as well).

Clutch, brakes and e brake. I recommend unfolding the slave cyl for the clutch and not breaking the line because they are a beach to bleed.

Oh yes, the brakes lol!
What controller (ECU) are you using on the 3800?

if you are using stock ECM for the 3800C/c I have all pins marked what each pin is for. I took it out of 96 Buick that little cover you can open and mod chip. my engine is out of 99 Pontiac GTP. if you go that way, cut off the harness a good foot long from ECM, you need those two plugs and continue your own wiring .it's not that hard to do.

I used the factory one and had zzp program it. I got my harness from James Brown and he will also program the ecu for you. The harness is pretty much plug and play just let him know it's in a stretch and he adds length to it.

What a build! did you do the swap yourself? This is gonna be a bad butt car when its all said done. These 3800 Fieros are nothing to sleep on. I've seen them outrun the V8 swapped cars easily.

Me and a friend did the swap in his garage. I also swapped out the springs to make ut a bit stiffer.
