Just let me know if i'm missing anything important that I need to run this turbo. Thanks

With the Walbro, you should get an adjustable fuel pressure regulator. The stock unit will get overflowed and start raising fuel pressure too high making tuning much harder. I am assuming you want to run a lot of boost, so get the 660 injectors as it will let you run more boost on pump gas. With the HRC S20g, There is no need for an external wastegate, it will not boost creep thanks to a 10cm^2 turbine housing design. Unless he already ported out the wastegate hole, stick internally gated. A 2.5 in exhaust would start to limit performance and you should really go to a full 3 inch O2 eliminator turbo back. Other things I would consider doing is getting ARP headstuds and a metal Mitsubishi headgasket as at high boost the head might lift a small amount and blow your headgasket. Also might want to remove your balance shafts to free up some oil pressure. Just as a last thought check your compression and make sure your too low on any cylinders.
The Super 20G is a good turbo and some people have put down some big numbers with them. I was considering it early but went Garret instead. At that price I say go for it.
