I want to upgrade my fuel system on my boosted Integra GSR '96. I currently have stock 240cc injectors, 12:1 Vortech FMU and inline fuel pump. Would my car be able to idle and run good if I got 370cc saturated RC injectors, 6:1 vorech FMU disc and a Walbro 255 high pressure intank pump? Or, would I still need something else?

it can depend on how much boost you're planning on running... you may not need injectors that size... right now i'm running 310cc in my teg and at first i was running too rich so after some minor adjustments we got the a/f ratio to equal out a little better, although i'm only pushing about 6 pounds of boost and all i need is the 310cc.

I'm planning on boosting atleast 12psi after I'm done with my fuel and ignition upgrades. That's why I needed a little larger injectors.

sounds straight to me...just make sure that you start saving up your gas money cause you can kiss your gas mileage goodbye, i'm running only 6 lbs and my gas diminishes real quick. You do a motor rebuild yet or r u running 12lbs on stock internals?

Yea I dropped my compression to 9:1 with JE Forged Pistons and also got some Eagle ESP H-Beam Rods, in addition to the ARP head studs.

About the Fuel economy - yea trust me I know! I used to get like 25 mpg now it's more like 19 mpg. Sucks!

So you think 370cc will be sufficient for 12psi? Or do I need larger?
And will geting a 6:1 FMU disc solve the idleing problem?
