I am trying to decide on which fuel pressure regulator to use w/ my new project... (turbo) ... but considering I am using a turbo that no one else has (as far as i know - garret t3), I dont know what disc to get w/ vortech.. so that leaves the aem and sard (assuming its adjustable too) ...

so, AEM's adjustable fpr vs SARD's ? I can get AEM for 165ish new, and sard is what? 140?

 

Ask Thomas (sx7r) on the SARD, he sells them for a good price. I have the AEM, and I think it's a good product. I haven't had any problems with it. I thought I was at first, turns out it was a fuel pump problem. For boost, your gonna need some sort of FMU, since the AEM and SARD are a 1 to 1 ratio boost to fuel pressure.

 

im sorry i might be retarded... can you explain that in more detail? thanks!

 

Vortech 12:1 FMU? good choice??

 

That is what i had been thinking only because that is what others are using, but how do I know I need a 12:1 vs a 11:1 disc since no one has this setup? Or is it always 12:1, pardon my ignorance and thanks for the help.

 

Just by P/N 6Z270-010 Recalibration Kit, Includes 4:1, 6:1, 8:1, 10:1, and 12:1. Its not much more expensive $44.60 -vs- $30.35 for a 12:1. I would think a 10:1 would be fine for up to 10psi. Before you do any serious boosting put the car on a dyno with a wide bend O2 sensor and tune it based on those readings.
