15g on a b series?????

i just did a D to B series swap here...i had my greddy turbo on my old d series motor which i really liked. i have to change over to a B series manifold in order for it to fit...but...is it worth it having a 15g over the greddy 18g that comes with the B series turbo kit from greddy? im only gonna run like 10 pounds of boost at the most...probably just 8psi most of the time though...the the little bit of size there make a big difference or what other turbo should i get the manifold flanged for instead of the 15g?...i want a street quick spooling turbo...that my appeal for keeping with the 15g....any opinions or info would be great..thanks

Well if u want a quick spooling turbo you should obviously be looking at a ball bearing turbo such as the apexi ones but if u only want 10 psi at the most just keep the 15g man i personaly dont think its worth spending the extra money. I think its only necesary if u go over 15 psi cuz thats where its gunna start dropping off and cant produce n e more pressure.

I agree! The 15G is efficient up to about 14psi, then it starts blowing hot air. A B-series motor would probably spool a larger turbo up more easily, so think about a T-series.
