Would the 0.84 a/r version perform slightly better given we've seen the compressor wheel is too larger, or at least larger than it needs to be or is it just as bad?
I was under the impression the gt-rs was the bee's knees for the rb25. I think there are more suitable turbo's for the sr20 as they run (from what ive seen) split pulse and can generally bring on a slightly larger turbo earlier, in fact that gt-rs on the sr20 graph looks laggy, i wouldnt even expect the rb25 version to perform like that.
a gt30 on an rb25 has that sorta response. also 24psi? that doesnt sound right, it would be way off its effiency i would have thought?
