Hello guys. I got and evo ix! My setup is FIC kit, full exhaust, bigger fuel pump, and ecu flash. My engine internals are stock. I was wondering what is better for a stock engine! to upgrade valvetrain with GSC s2, retaintes and valve springs, bigger fuel injectors and camshaft pulley or its better to get an FP54 Green with the stock valvetrain ? Thanks a lot for your time! I will appriciate any advices.

 

Turbo upgrade will definitely be the better option, much more power will be gained from it.

 

Thanks man!!! How much power can stock evo ix cams can handle? i know that rods has restrction over 55nm!

 

It really depends on the turbocharger. Abacus made 600whp or something like that with an FP red on an all stock Evo9 engine.
