Tire-Kicking GVR4s Again [HELP]

@Jesse W

I’ve never heard of an ISC frying an ECU, and I can’t understand how it would happen.

But, that’s irrelevant now, nice buy!

I think the most aggressive cams were the 93-94 stuff. You’re better off going something like HKS 264/272 or so (FP1/Comp equivalent, whatever you can find form some place reputable.) I know AMS did a cam test way back when. I think they made the most power on 264/272 on a small turbo.

Need to run, but if you need any, post it up.

IIRC
90 cams are different, 91-94 are all the same.

also, IIRC, that test made the most on 264/264 HKS combo (small 16g maybe?). The 272 had a slightly higher peak, but cost both torque and mid-range hp. The 272s aren’t necessary until the rest of the system is breathing far better than stock.
