Re:Rod difference D16Y7 vs. D16Y8
 

thanks...so if I ever wanted to upgrade from the 15g, couldn't I treat the Greddy manifold like an STD manifold and just use an adapter plate? one last thing, will I need a fuel pump with this setup? (450cc,15g,6-7psi,AFC) THANKS EVERYONE you guys make all the difference

Yup, you could build an adapter plate to mate to another turbo no problem..

You shouldnt need a fuel pump running that low, I would replace if you are going to boost into double digits.
