forget "the great deal on t3t4 turbo" and get one that works well. gtx2867r, gt2560r, efr6758, that kind of turbo.

Yes, there are no "great deal" on them, and that is because they work.

Injector size depends on the boost you want to run and the fuel you want to use, but you can't go wrong with 1000cc EV14 based injectors. They are newer tech and will be easier to map than 20 yo 440 or 550cc (and will work better).

Look at HKS injectors, all kinds of sizes and reasonably priced. I was just looking at them for my Rb yesterday. Set of 6 720cc's for like 300$.

Use this hks fuel flow calculator! Super handy tool and should give you a direct answer to your question! http://www.smartfireinjectors.com/eb...flowchart.html
