I want to sup up my 2012 g37x. Does anyone know how much horsepower the factory awd system can handle? Or recommend other options.

thx

 

Upgrade to sport brakes and refresh or upgrade your suspension first. Then start worrying about hp gainz. Long tube air intake and aftermarket exhaust are what most people start with. But I suppose you could go straight to forced induction and just start replacing things as they break with stouter parts. But trust me on the brakes + suspension.
