Looking at your car wicked car!

C2 cams with 8/1 compression pistons, .8 bar boost, and a little intake porting.

If you do not want to do the pistons or mild porting, SC cams are the standard go to.

Do note that you would be best served with SC or any cam upgrade going with resurfaced rockers and high performance valve springs to deal with the higher lift.

However, where do you want to make your power?

Stock cams will make more TQ than HP. SC cams will make about equal TQ and HP, C2 cams will make more HP than TQ. You can move this around depending how they are timed. For example SC's can make peak HP anywhere between 5500 and about 6300rpm.

Where you make your TQ determines your peak HP.

300# TQ at 5000, 5500, 6000 or 6500 rpm makes 287hp, 316hp, 344hp, and 373hp. All making the same power with each RPM.

I believe if stock cams are optimized they will work best in town with the stock gears. Compliment this with a quick spool small turbo (GT 30?), optimized ignition timing, about 13.5/1 AFR off idle, and it would be very quick off the line and might even make for a higher level of usable average HP in first and second gear than more aggressive cams.

However, I do think a little differently about these things than others.
