Ive got one off my Vortech S-trim supercharger that I never installed. I programmed my pcm instead. Vortech PN#6Z110-117 8:1 FMU with fuel lines lines. Not sure how it would work with a turbo though.

anyone else??

Had one off of my old Vortech that I sold as well. Check the forums, most people swap in injectors pretty soon after installing the kit.

what do u mean about injectors?

would a fmu of a vortech kit work on a DIY remote turbo?

For instance, the fmu that I mentioned^^^ will raise fuel pressure 8 PSI for every one PSI boost. Example: Normal fuel pressure=+/-43PSI. Lets say 6lbs boost should raise it to 80+psi thus richening the injector to handle the boost.

Now on the other hand, I went with 42LB SVO injectors and had my PCM increase BPW( base pulse width) to richen out the mixture to handle the boost. It would be better to get larger injectors and have the PCM tuned for the boost, But if $ is an issue, The FMU is the way to go(no tune and keep your current injectors.) FMU's can also be inconsistant with performance and 80+ fuel pressure isn't good on the injectors. Id prolly let mine go for $100.00 plus shipping if your interested.

ok would a vortech supercharger FMU work on a rear mount turbo?

A FMU will work on any application where you increase boost and therefore wish to increase fuel pressure and therefore increase fuel richness.

Doesn't matter if it is a FMU from Vortech or ATI or where ever..

Just remember as posted above that FMU's are a basic starter type setup and are inconsistent at providing a repeatable, reliable, fuel mix enrichment.

That's why most forced induction guys go to larger injectors and a reprogramming of the PCM

Don't waste your time and money with an FMU. These units are bandaids at best. Get some larger capacity injectors, and reprogram the PCM.
