This is a 1986, and the engine compartment looks like mine. Note, they put "Tech-4" on the air cleaner, but it's not a Tech-4 motor...




I just came across an 84, and it looks more like yours. I guess yours is an 84?


this is the white 84 we put an engine in. hence the title of the thread since it needed another

That's a good size throttle body I see there. Should give excellent throttle response. With al that work I hope that it rewards you with strong performance. Look forward to hearing the results of a road test.

the reman block I got (stock replacement since the performance one needs to go be checked for cracks professionally and it wasn't worth the effort of putting back together yet) has a broken start bolt. gonna heat the casting and drill the bolt out and then hammer in an extractor but I'm pretty annoyed since I got this block for 300 from the guy I bought the white 84 from. guess I'm not buying stuff from him ever again.

The flywheel looks fine, but you'll want to get some ARP studs. Those flywheel bolts should not have sheered like that. My guess is that they didn't torque them down properly and / or they didn't use thread locker on them either.




I was going to comment on the fly wheel as well. They did NOT sheer due to too much power. Something else was wrong.
I have stock bolts in m y SD4 engine, It probably makes around 170hp and no problems with my flywheel and/or bolts.

LOL... I got so distracted with the content I forgot the title.

What are you looking at specifically? It looks like a stock 84-86 TBI unit. Is there something modified that I'm not seeing?

in our case it was the engines power. we put another duke in (just 120) and it was significantly slower. seems like the old stuff was built up for a 300 hp turbo build that didn't happen.

that is a stock one that's got a larger plate in it at least on ours. also 3rd engine was the ticket but unfortunately isn't making enough power to rival our formulas 0-60 time anymore. soooo maybe a turbo is in the future for this car

Nice! Was that something you did, or you bought it that way?

Is it bored straight through the intake as well?

bought it that way and intake Ports are matched and it looks like someone ran the casting reaaal thin in a few areas while porting. I'll likely end up making a custom intake for the built engine as well as equal length headers

If you happen to get it apart again, I'd love to see a picture.

My daughter has a Holley TBI unit, which of course has a larger throttle plate... and it essentially does NOTHING when used with a stock Fiero intake because the opening for the TBI is no bigger than the stock TBI's throttle plate. I've thought about possibly buying a second one and boring it out to the size of the Holley TBI unit.

It used to be the Offenhauser and Holley intakes were pretty common, but I haven't seen one pop up on eBay for years now...
