Duration, manifold and timing makes the biggest difference in spool time. A 2871R is going to spool slower than a gt25 frame, but its going to make more power.... people actually need to read this thread not just ask questions some times. lol

Nice summary. I never thought of it that way. I had the greddy im too and iirc i hit full boost around 3500-4000 rpm. The gt-rs spooled pretty fast. It was always cool to hear the turbine shaft spinning after the car turned off b/c of the ballbearings
