Higher compression spools the turbo very quickly. On my auto I would reach full boost by at least 2,000rpm.
I lost compression after 40,000 kms of N/A+t, and I didn't drive it gently either. I was going to do a stag n/a+t swap with a larger rear housing turbo, but decided on reliability of a det swap which on stock turbo and internals through a heavy duty auto box netted me 215rwkw with a e01 boost controller and emanage blue ecu running map and afm simultaneously, tuned by Paul Fisher at Pulse racing. I'd take the swap over bolt on conversion.
