Hello everyone I built a quad-4 85 Fiero se some years ago and have done tons of mods. I blew a head gasket and found some cracks in the head and block of the 1990 low output quad-4. So now as I look for parts for the engine I’m faced with no parts and either selling the car or putting a more common engine in it. I have a 5 speed in it and was in process of installing a remote super charger. I thought the guys and gals here may be able to point me in the right direction for parts in any direction that is the most dependable drivetrain wise. I also have tons of knowledge building custom cars from modified stock stuff to repay the community. I built my own bump steer eliminating rear control arms, put hiem ends in place of the rubber bushings in the front lower control arms, I run an ecm from a turbo sunbird and made my own wiring harness from the 1990 grand am weaving it into the Fiero. I tune it and burn chips, run code 59 and a moates chip burner. I also have lots of parts I’m not using and probably need to sell to fund a swap. It would break my heart to just give up on it after all the labor I’ve put in but I can’t be spending thousands on getting it back on the road. I have a lead on a sc 3800 car but it’s an auto trans. I just can’t find exactly what I need searching the garbage heap internet so thought I’d ask y’all. Thanks for reading and for any help 😁[img]https://images.fiero.nl/userimages/ABanks78/59EF42D1-68 5E-45AE-910B-9D929B1DE577.jpeg[/img]
quad fours are cool little engines, I see them all the time at local you pull it lots, but parts quality is questionable. I don't have much to offer other than that. I hope you keep the car a quad four, just because it sticks out a bit compared to a 3800, and it sounds like you have a bunch of work in it.

I invited Lou Dias to trash me in my own thread, he refused. sorry. if he trashes your thread going after me. I tried.
I haunt those pull it yards but cars that old r getting rare. I found 2 Fiero’s,a gt and a newer one with the round bumpers at one close but I can’t really use anything from a stock one anymore 🤦♂️ And yeah I’d like to just fix it and put the supercharger I have on it. Makes good power and lots of room under hood
Quad-4 was a cool engine, but it's been obsolete for a long time.
Some parts are getting harder to find but hard to call an engine that makes 180-190 hp from 2.3L N/A obsolete. Plus there's the fun factor. When a Quad 4 hits 4000 rpm it feels like a turbo kicking in.

Amen. People who know Quad 4s know how awesome they are.
