are you gonna be sticking with that turbo for awhile? If that is the case and you want to get maximum power out of that turbo (this also means running larger cams) then you should go with a minimum of 650cc injectors which are good for an estimated 390-400whp considering your tune and fuel pressure are good. 740cc injectors will get you an estimated 450whp at least also as far as the fuel rail just run stock. no need to upgrade it because IIRC there are no upgrade side feed injected fuel rails..IMO that upgrade is not needed. your money could be spent in other places..as far as injector brands i have only had experience with sard and i have had no problem..been running them for a year now

With my 2871R setup I run Stock Fuel Rail, Deatschwerks 740cc Injectors, and Nismo FPR. The 740cc injectors probably max out around the 450-500whp range which the 2871R wont get to anyways.
