i need some help. i'm doing the custom ct-26 turbo setup. i know i have to gap the spark plugs to .030 like the 3s-gte. which plugs should i get? also, what kind of oil should i use. i am going to use synthetic, but does it matter what kind and what weight? thanks, i should have the project done in a couple of weeks. also, how do i control boost levels? how do i know how many psi i am running without just running it and reading the boost gauge?
thanks,
adam

you will need some sort of fuel system upgrade if you want to boost. an NA car is never ment to have more than 1 atmosphere of pressure and because of that even if you turbo the NA car, the car's ecu will want to either fuel cut(caused by MAP) or only give enough fuel for an NA setup.

an fmu is the cheaper and faster way to upgrade the fuel system, although i have heard that the GT fuel system maxes out at 160hp(replace the fuel pump at that point) you could go with bigger injectors but then you would need something to control the injectors(safc).

Jason, what kind of fuel upgrades do you have? im not 100% sure on the 5sfe but with the 7afe, fuel work is 100% required
