mild build
 

have a stock z6 that we be getting overhauled.
the head will remain stock with the exception of new vavle springs and any maint. items needed to seal properly.
as for the 252k stock bottom end , im looking at vitarals and the fjt rods in hopes of a healthy 250 at the wheels. I know i need to be somewhere in the neighborhood of 415-450(2.17-2.2) cfm to acheive this. My problem is I want to use a small 16g or other stock turbo to obtain these numbers and based on the specs for the turbo it should be good it is some where around 505@15psi. But i have a(n) jg edlebrock turbo manifold.. I dont thing the flange will work... any help?
Im trying to be budget minded with this build. I figured some precision 680cc injectors would work nicely

This will be an autox car and a daily driver on occasion.

pics?

The edelbrock turbo manifold has a standard garret t2 flange on it. This flange is found on aftermaket garret turbos (t25xx, t28xx, etc) and factory nissan turbos.

You can use this adaptor to put a standard, single scroll td05 mitsu turbo on the edelbrock manifold. http://www.bmcrace.com/b-t-g-adapter...1cc9rl1i836df1
