thanks everyone for their input. i've pretty much come to the conclusion that i'm going to leave it stock, for now anyways.
if standards good for 300kw i dont think i need to worry about it. to be honest, i just wanted it to dress up my engine bay.
i'm just pissed i bought a stock 33 in the first place. with all the mods i've done, i should have put a new donk in a heavily modified one or got a gtr.
it$ all adding up but i'll get over it.
