Yea, catalog said GT3040 ballbearing, spools around 4k. What turbo is your friend running? I sized my turbo for 500 crank HP. I think I would have made it had I not had boost solenoid problems on the dyno. I haven't been back to test.
Ive always liked 510's. Would be and awesome car with an SR. I thought about going that route but decided the Z car was more of a classic style.
