Start with an Injen intakeThat is a waste of 250 dollars, just buy a K&N filter and keep the stock box,now get better motor mountsFront motor mount is sufficient for now, and then get some HardpipesThat is another waste of money, the stock pipes are good enough for low boost, if they are leaking then upgrade but they most likely arent (go on ahead and relocate your maf), then your going to want to open up the exhaust from the manifold back (hopefully getting some of the responce you lost with your intercoolerzilla)Dont waste ur money on buying an s-pipe. not worth the trouble or the gains for the price, now its time to get your LSD weldedgood idea but will be expensive, and a good clutch-flywheelawful idea, the stock clutch is mroe than enough for 10 psi, and a new flywheel is expensive if he is trying to save money, and-synthetic tranny fluid, get some ebc pads and rotors all around, and some steal braided linesonce again if he is trying to save money not necessary, i have stock lines and my car brakes like a mofo, Now its time for a unichipi would go with the A/F controller, better wastegate no need in replacing right now and some good gauges, oh and better injectors (WRX), go and get a good tune. Might as well get a deep sump oil pan as wellanother great way to waste money at this stage, the stock pan is more than enough, even on a built engine. NOTICE HOW I NEVER SAID JUMP THE BOOST! for sure rods are weak as ****on an unopened block this is like popping a soap bubble.
