Going to put on a nismo eventually once I get some spare cash, just started back at college and buying books has left me strapped fopr cash, anyway can you run 4 bar on a stock FPR? If so how? I read how to do this somewhere on a previous post, and cant seem to find it.

Thanks,
Brennan

I would not see how 4 BAR means 4 BAR of fuel pressure.

There are post on here on how to make a adjestable FPR out of a stock FPR, you might be able to to this for cheap. I think Charle2020 made and thread about it and had pics, I think the pics are gone now but its worth a shot. Try to search under his name and maby "make FRP".

also do you have a fuel pressure gauge? i got a gauge and adapter i can sell you for cheap.
