I'm doing a Blox intake manifold swap on my GS-R and I'd like to know what the ideal fuel pressure should be. I'm installing a B&M fpr with gauge too. I have an Iceman intake, DC JDM 4-1 header, and 2.5" straight pipe exhaust(no cat). Thanks in advance.

 

with what you have... i'd say just leave it at stock settings.

 

agreed 100% when i threw on my skunk2 intake and skunk2 cams i left my fuel at stock, i just raised my vtec engagement, but now that my car is turboed different story

 

I don't have my fpr or gauge installed yet, so what is the stock fuel pressure set at?

 

im sure some one else will be able to give yu a better number but i do belive its around 40 to 45

Install the gauge first, and see what your stock value is. Then just set the new regulator to the same pressure. Remember to perform the adjustment with the vacuum hose disconnected.
