Title: Which motor?
Post by: Ccemn1 on September 15, 2017, 07:55:28 PM

Since I have so much work to do in this IFG, Fiero based, Diablo, I'm thinking of upgrading to a GM 3.8 liter.
I'm completely new at this game. Can anyone guide me in the right direction as to what year, model and specific engine I should use, with no clearance issues, or major engine, or Trans Mods?
Thanks in advance.

OK , LP set up is a lot of work, engine, transmission  ( more or less an AUDI )adapter  plate, motor mounts , axles, shifting and that's just the basics to start and that's like 5K $ or more right there beside the labor
on other hand ,transverse you can drop 3.8  or 3.8S/C in Fiero transmission or get complete set up from donor . less work but nothing over the weekend.
I think I post it for you when it comes to FIERO about any mods from mild to wild  go to

Thank you. That's all I really wanted, was to drop a 3.8 into the engine bay & mate it to the standard 5 speed. I figure an extra liter of displacement should make for a substantial gain in performance.
It's just that there were so many different GM 3.8's through the years, I was wondering if any specific years, or models, worked better than others, as far as clearance issues, and mating up to the Fiero Trans & motor mounts?

Can you tell me what kind of lifting struts you used on that hood?
Mine had the hydraulics, but they're both missing & I can't find ones to replace them.

I can tell you do NOT go with a 4.3 ltr Vortec, especially if you go carb'd like I did.  I could have gone with a different motor for far less $$ but this is what I had at the time.  It will be pretty good motor though and I took it around the block a few times and it's going to move!  IF... I can keep the tires planted to the ground.  haha.
