I have a 1991 rs with a 3.1 in it. i was just wondering what all i would have to do to put an LT1 in. I can get the LT1 really cheap, and my car is in excellent shape so i dont want to sell it and get a v8. that seems to always be the advice.

 

how much is the lt1 you can get ahold of?

 

800 bucks

 

that is with almost no miles on it

 

what little i know about this swap...you will need the complete wiring harness, fuel pump, the ECM, transmission, radiator, lines. i dont think you can use the A/C unless you do something special( i cant remember what)there are two long ongoing posts on the board about this swap. theres lots of things to change.

if you'd look around before posting you would have already found your answer. look at Swapping LT1 93 parts one and two and youll find the answer to just about anything you want to know about the swap.
