I wanted to get a discussion going about cam choice for an SR20DET paired with an EFR 7163. I currently have Tomei 260 (12mm lift) solid lifter procrams in my setup. With my old turbo, I enjoyed a pretty broad powerband, but it did lose its breadth after 7,500 rpm (power came on hard around 4k to 4.2k), which my engine could go higher, but there wasn't much point. Obviously going from an old GT3071R to an EFR 7163 is going to change things quite a bit, but I've been considering dropping in a 270 (12.5mm lift) procam on the exhaust side to give it a little more breathing room up top. Car is being built for TT1 with NASA and Limited RWD for GTA for reference. Not a street car.

BTW, I know the VVL heads are better, just not there yet in my build process. I will do it eventually, but the DET head (which mine has oversized valves and port work) is staying for awhile to focus on other aspects of my car's build.
