to me it seems like you just wrote out a parts list of stuff you want to do to your car. Get the motor in the car and running perfect before you think about doing any modding. It will save a ton of headaches in the future. Judging from the fact that you dont know what size injector to run with this setup im guessing you havent done to many modifications to motors. RB's are EXPENSIVE just to let you know. But done right, they will take all the abuse you throw at em

umm i already own all these parts... they came with the motor... the motor was running fine in his car but he was running an afc and low boost. So i picked up the emanage and wideband.... I just wondering if 550's would be good for this setup running prob 14lbs

emanage + nissan ecu + large injectors = fail.550's are good for about 400whp before they get over the 80% duty limit.

well the question is how fast do you want a melted piston...do it right, do it once.
