if im runnig a greddy g18 turbo kit with intercooler and apex i exhaust what extras would i need for the turbo to work correctly, and its on a stock Ls motor.

 

To answer your question, you have the greddy kit right? turbo, manifold, downpipe, bov, wg, and Emanage too. correct??

Greddy kits is more of a bolt on turbo kits.. Hook everything up. The e-manage is limit you to certain amount of boost..7psi I beleave. So you should be good to go with the greddy kit..
