If you want to get the most out of your Ecotec V6 then these are the Turbo Manifolds you need. Designed and Tested on our own Test car, we found quicker spool time, Increased Air Speed, Less Back Pressure, More Power with Less Boost.
We made 350rwkws on 18psi with a GT3582R on a Standard L67. With our Race Series Manifolds we made 367rwkws on the same 18psi. We raised the boost to 19.5psi and made 398rwkws.
