Will i have idle problems by installing a walbro fuel pump (199lph) by itself w/out an adjustable FPR?? I have 310cc injectors by the way.

 

nope my buddy had this setup on his civic

 

you'll be fine but it may raise fuel pressure. there have been quite a few instances where it would raise FP ~10psi..

 

I'd skip it for now, you'll just be running rich untill you get the FPR on there.

 

well better rich then lean, i should also probably point out that this is a greddy turbo kit w/the blue box. People tell me the blue box make the car run rich, well my car is not running as rich as people say, in fact i checked my plugs the other day, and the look a little lean.

 

A fuel pump won't do jack. Get larger injectors.
