i will add though that what you are saying is correct i just came off wrong cause part of my problem as well was the fuel pump (which i changed out for one from a gsr which flows the same as the what the b16 needs) the octain level is what was causing the knock
ps i stand corrected
pss but i still stand on the higher octain level for the turboed gsr but like i said i will find out details from him for he is a way smarter man than i.
