We’ve had great luck with the DC21 cams from Dougherty on the 993tt builds. I am also running it in my 993 turbo conversion. The ideal cam timing events will change based on CR and turbo back pressure. The cam uses 993RS intake profile with GT2 exhaust profile. It’s a mild/moderate cam and gives great street manners. Don’t overlook the GT2 profile either. Open it up a bit (113?) for better idle and low speed manners. If you’re really bold go DC24. That one should be a screamer! Not sure how snappy the off boost response is with GT2 or DC21 though. Call John to discuss your car, driving patterns and what’s important to you. He won’t steer you wrong.
