I'm pretty much at my wits end on this subject so before I go off the deep end beating my brains out i'm just going to ask a question that so many people mull over in there heads...whats it going to take to achieve more horsepower (575+ figuratively speaking) that will last for a bit. Sorry if this comes as a played out cliche, buts seriously jumping from thread to thread forum to forum, really takes a toll on you lol. So If you guys have anything and I mean ANYTHING to get the ball rolling please feel free to let me know.

What do you mean last for a bit? Those kind of HP numbers requre a big turbo, lots of good fuel, and a great tune amongst other things. Your not going to get it with the 99 spec turbos that for sure. Plus I would not plan on that much HP on pump gas. Poke your head around the single turbo section and see what people are running that are in the HP range you are targeting.

 

I don't think a "high pressure cap" or "silicone hoses" will give you extra hp either.
