Thread: Someone stuffed a 3.8NA in a 3.4 car... now what?

More pics please! I can see it is white, so its not the car I am looking for, but like previously said not a very common swap. You wouldnt think it would make much difference, but boy is a 3800 in a earlier Grand Am is a whole lot of motor!

Check out the link in the above post, those are the best pictures I can get at the moment. I'm going to try to figure out some way of getting the car off my lift tomorrow and get it outside in the sun.

why not swap an l67 is my question....

Thought you were looking for a Grand Am GT. This guy has a Grand Prix GT. Rare model sedan from '94 - '96 (GT was a coupe prior to '94) that came standard with hood louvers and the 3.4 DOHC.

Yeah, mine's a 94 GP.... Which I may add that some jerk installed command control ride on as well, I found out today....butt end drags the ground and front end looks at the sky.... that sh*t comes out and gets replaced with Cadillac ride control, if not just regular old McPherson struts.

Where have all you guys been? The 3800s have been swapped into just about anything you can imagine for YEARS. Fiero, Sunbird, Cavalier, Sunfire, Cobalt, FWD a-bodies, etc. And yes, even quite a few Gen I w-bodies. There was even a whole website devoted to swapping the L67 (Series II 3800 supercharged) into anything. MotorSwap

Your GP being a '94, you have OBD1.5. First thing you'll want to do is find out what year motor it is, and what it came out of. If it's a '96+, it's going to have OBD2. Easiest thing to do would be to grab the whole wiring harness from the appropriate year/car. Personally, if you're going to go through all that trouble anyway, I would just find a '99 & up L67, and take the motor, trans and computer from it. They can be had cheaply enough these days to not make the savings of sticking with the n/a motor you have worth it. If you can find the wiring harness from a '97 or '98 Chevy Lumina/Monte Carlo, that will be the easiest to work with for you, as it was a "Gen 1.5" w-body, so it's designed for a Gen I. You'll also want to snag the exhaust/downpipe from one so it'll fit the Gen I. I think you also may need different/custom axles, too. Here's a good thread:
