i got a y8 /14b/ 2.5" charge/exhaust, i think exhuast makes a difference in spool time a little too, put a resinator on and it seem to spool slight slower, about 3.8kish for me to. also the hot weather makes my ---- just all around slower, cant compress the hot *** 100 degree air as good or soimthin.

sucks cause i was sellin my car, let this guy test drive after talkin for a while, car felt slow as ***** 3 people in it it was like 98degrees out

 

My old 14b/z6 with a 2.5" exhaust started boosting right around 2800. Full 12psi was about 4100 with the old-school carb spring wastegate setup. That thing actually worked really good too...never dropped below 12psi in any gear

 

hahahahahahahaha

 

you could turn it up to 15 lbs without it grenading but you might wanna bump up the rising rate to compensate :1
Oh the d15z6 does not exist. Its a d15b2 thank you very much I have the same motor. On the block its just gonna say d15b right?. How does a small turbo take from 2000 to 4000 to spool up?

 

you are a retard, so please do us a favor and STFU.
