33 isnt an option on his power/weight laws.
SR S13/180 isnt either.
I still say R32, the way you drive, SR will POP, RB20 wont as easily, and it wont spend enough time under 4k to notice the lack of low down, and the S13 you spend a lot of time in accentuates the boost transition compared to an S14 with the VCT(S13 noticable, S14 smooth) where an RB20 just smoothly revs out, which makes it feel like it has more down low than it does., that stock s14 was gutless, smooth but meh... catback to finish the exhaust and remap would change that though.
