i am desperately looking for a z6.. but i have found a good deal on a jdm d15 vtec, i think i might settle for it just because i have been waiting for sooo damn long... would they both make the same power at the same boost level, say 7psi on the same turbo and all that crap? im thinkin the z6 would make more, but then again i always seem to find exceptions to my rulings
