Well I just purchased a super clean 1995 bonneville regular 3800 II. I also have the abillty to buy a 1997 GTP that was hit in the nose and totalled. The guy purchased the car back from the insurance company because 3 months before he got hit it had a new GM long block put in because the spark plug let loose and killed the cylinder. The motor in the car has 6200 miles on it the rest of the car 96k miles. He was going to try and fix it but now he realized he never will. He wants $1000 for the car. My questions are should i buy and put the motor/trans/pcm combo into my car, or just spend $1000 on upgrades to the N/A 3800 and run 87 octane? If i do the */C motor swap what do I need to do in order to get the car into the 13s? I figure while everything is out of the car it will be a lot easier. Thanks in advance, Ian
You can swap it however the 97 PCM can be a PITA! If your are seriously going to do it, I would defineately invest in a 98+ harness, PCM, and Evap sensor. The 98+ are less sesitive to changes. There are only a couple ppl. crazy/or dumb enough to swap a 97 setup into a car. We have done it in a Cutty, but the Cutty was a 97 also.
I dont know if the Bonne'* are like the GPs in 95, its not really OBD1, its more like OBD1.5. We have a few ppl. in our group that have done the swap OBD1 to OBD2 with an L67 swap. If your interested I can point you in their direction.
