I Just purchaced a 95 gsr with a b20. This car is realy fast, but the guy I bought it from knew nothing about it. Can I get some advice to figure out what I got? I dont know where to find the stamp on the trany, but I know it has to be a good one. At 4000 rpm I get second gear chirps and at 6000 rpm it get crazy wheel spin when I shift to second. The guy told me this car can beat mustangs and cameros. I didn't believe him at first, but now I think he might be right.
