I just blew the LT1 motor I have in my car now. I have a compleat parts car (98) Fire bird, With an LS1 its only got 36,000 miles on it. I have the 6 speed tranny ( T56 I think ) I need to no if I can bolt the LS1 up to that tranny???

Buy the way nice Board

 

The t56 should bolt right up.

 

Thanks , I didn't wanna use the auto. I printed the section on doing the swap and it didn't say. I'ed like to use the drive shaft rear end as well but I read more befor I do it.

 

Uh...if the T56 is one for an LT1, you'll have issues using it with an LS1. Input shaft length is the big problem.

 

Yes the t56 is for an LT1, Dam Am I going to have a big problem?
My car is a 96 and my doner car is a 98 Are there that many differances. I can use the motor mounts from my 98 as well right insted of buyin some? Dam this is turning in to more hastle then itsa worth. I may just sell my LS1.

 

If you consider needing to replace the T56 input shaft and the bellhousing not bolting up completely a big problem, then yes you'll have a big problem. And that's the easy part...keep reading.

Wiring harnesses aren't plug and play, you'll need to map out both the LS1 engine harness and your 4th gen chassis harness to figure out what repinning is needed. And then there's the fuel system...your LT1 had separate fuel feed and fuel return lines. If the LS1 came from an F-body, it only has a feed line...return is back in the rear of the car.

As for the mounts and other trauma, no clue...you're asking 4th gen questions on a 3rd gen board.

I'd check the Conversions & Hybrids board on ls1tech.com for posts from other 4th genners. I've seen at least one well-documented 4th gen V6 to LS1 swap there, take a look and see what you're in for.

sorry my bad: I didnt realize it was a 98, i was thinking it had an lt1, not an ls1.
