Very very confusing limbo...i know how it sucks i was trying to figure mine out for a while but i finally got it in the end. yer I dont think it will be an RS with 52.9mm inducer. What Flange is exhaust and manifold sides? T25/T2 with 0.63 Right?

Have you put it on your car yet? the 76r will spool alot later...if its on the car whats the rpm spoolage etc?
