Who's all running one? Which ratio do you have? I kinda sounds 12:1 or 10:1 sounds crazy to me. If I were to run 10lbs of boost with 12:1 FMU my fuel pressure would be @ 120lbs + base fuel pressure? Is that right? Planning on running 8-10lbs on B20 nonvtec which FMU do I need? OR would a injector upgrade be better? Any input would be much appreciated, thanks

Injector upgrades are always better for the very reason you're worried about. 120psi or more is not good. You can lock up an injector that way plus with that high of fuel pressure you can't really get the best tune on it because fuel is blowing right past the nozzle even when it's closed.

With a set of 440's you can run base fuel pressure with a 1:1 regulator. Combine that with a Hondata or AEM computer to control everything and you can fine tune it to be both safer and more powerfull.

You must be going turbo, the JRSC FMU is a 5:1 rise rate.

Does anyone no how to wire up a injector resistor to use low impedence injectors on a car that came stock with high impedence?

Tobi just did my car last week. He put in 450cc DSM injectors and a resistor box.

He does great work and charges fair prices.

Did the DSM injectors plug in to your harness or what did you have to do there? I was thinking after the prelude injectors that I have are maxed out, I could switch to those. The prelude injectors pluged right in for me.

You need the DSM injector plugs..............try 2000SIVTEC he should have injectors and I got a resistor box and injector plugs at the junkyard for him.
