I purchased the 4 bar 370 set up from travis and was curious to know what type of fuel pressure regulator would work well with this setup. Do I need any particular regulator or does it just need to be set at 60psi or so? Thanks

I spoke to JWT about the same topic. They told me with a 4 bar program the fuel pressure regulator should be set to 58 psi.

I am using an Aeromotive FPR (I am very happy with this FPR) which requires you to buy some fittings, but it is not very difficult to install. Another alternative is the Nismo FPR which Isidro sells, the Nismo FPR mounts on the stock Fuel rail, where as the Aeromotive does not. I have heard more good things about the Aeromotive FPR than the Nismo. At idle the FPR needs to be adjusted to right around 51-52 psi. Next pull the vacuum line (this will simulate full throttle) the pressure should now show ~59 psi (58.8 psi=4 bar). Hope this helps.

but what do I know. Good advice guys.

You need some sort of aftermarket adjustable fuel pressure regulator so you can adjust your static fuel pressure from 3 bar (43.5 psi) to 4 bar (58 psi). Aeromotive & SX are the most commonly used. If you need an Aeromotive FPR let me know. I can get them. You can email me @ louisanaya@hotmail.com
