I am looking into buying a LT1 Trans Am. Im going to be stroking it to a 383 and putting a H/C/I combo on it. Also i will be running a 150 shot of nitrous. Should I but an older trans am with the OBD I computer or get a newer one with the OBD II??? Which one would be easier to tune and easier to mod like i am going to do. Any info would be appreciated. Thanks

 

I think most people on here will tell you OBDI>OBDII, There are less emission controls with an OBDI i think, and you can have pcmforless.com tune it

 

OBDI. It's easier to tune. Get a 1995 car. The 1995 LT1s have vented optisparks, while pre-95 models don't.
