only if ur upping the fuel pressure higher then stock, otherwise a stock fuel rail will do just fine, but it looks like ur uppin the fuel pressure with ur 310cc's and that fuel pump

well my car is at the shop now and will be dyno tuned monday but b4 the head was installed it was at 40psi. so i didnt ask my mechanic if he will go any higher on the fuel pressure. but i will ask.

Waste of time and money on an all motor car. You need to up the fuel pressure WAY higher than stock to need one. Stock fuel rails are fine for even low boost Turbos/SC's.

I can't believe you did that much searching and didn't find a thread where I said that, cuz I've said it about 50 times now. :???:
