S15 480cc Injectors Side Feed

As above, i know the S15 used 480cc side feed injectors which will drop into the RB25DET fuel rail with no problems. Now the question, do i need to upgrade the fuel pump if this is the case.

yes will fit no you don't 'have' to change the fuel pump just the settings on you power fc to compensate for more flow from bigger injectors. From memory you put the settings to 82.5% and +.056 (I don't think you can get it exactly that amount) . latency time isn't that important in my opinion its only out by a very small amount.

Installing a bigger pump and getting a tune will get the best from the money you've shelled out(I'd be installing a Z32 AFM whilst i'm at it to get the best results as you'll find the the AFM is maxed as well)

Thanks for the info.
