You can do alot with CIS. I'm a newbie to 930s and there's a lot of knowledge on this board about modding 930s, but it seems CIS limits you to @ 400whp. To go higher than that, you need EFI. The first steps for your car I guess would be for a free flow exhaust. Then you add in a bigger intercooler and turbo. Lots of different turbos out there that guys have used: k27, k27hfs, k29... I have a k29 on my 86 and the turbo starts spooling @ 3k and pulls hard from there up to redline. I have no experience with the k27 variants. Just make sure you up the fuel as you don't want your car running lean at WOT. After that, you would be going into the motor with cams and P&Cs.
