My GT2871R .64 ar is on the edge of being autocross friendly with peak boost at 3800 rpm and a 3.91 J30 lsd. I am switching in a skyline R32 4.36 R&P to keep me in the boost in 2nd gear at autocross events. If you want a low 10 second drag car and a drift car you will need 2 cars and that's the bottom line. The largest turbo you see on the baddest time attack 240's in the US are GT3071's and I don't think you will get in the low 10's with 450-500 whp. Most drag 240's running low 10's to high 9's are running GT42 or T67 turbos. IMO, you will need at least a GT35 or larger setup to break into the 10's in a 2600lbs S13.
I have been torn between the 2(drag/autocross) for the past few months and there is no happy medium. Replace my 2871R with a big laggy setup and break into the 10's just so when I put my steet tires on it liquifies them at the first sign of full boost. As of now I am setting up my suspension for autocross and lowering my gear to the 4.36. Then I will be retuning with JWT cams, topspeed intake, and methanol injection.
I am hoping for a car capable of low 11 second passes in the 1/4 with wrinkle walls, a 2 step, and a good 60 ft time that will still be friendly at autocross events. I am considering a GT3071 or GT30R setup but I will probubly regret it at autocross events.
Sorry for the novel, but low 11's and drift/autosross friendly are the limits of the SR20. IMO, if you want to do better than that you will need 2 completely different cars.
