Alright guys, i have a jdm d15b non vtec block with a y8 head and my b7 dizzy, stock p28 ecu, and everything is good, but when the shop put it on they had really bad detonation because of the high compression so they had to retard the timing all the way.....and i was just wondering how come my vtec dont pop hard.....maybe be cuz of it being retarded all the way? or is there something else i can do to it......the timing is only gonna be retarded all the way until i get bigger injectors and fuel pump then it goes back to stock......HELP PLEASE i want vtec to crack lol

10.65:1 compression is not high compression. If they had to RETARD the timing to stop the knocking, cam is one tooth advanced.

Which cam gear did they use?

Already told you where to start.

Your timing I'll bet is too far advanced right now due the the cam timing error :)
