Anyone ever put a fuel pressure reg on a standard 4efe .... If so did you get any gains??

[Gainzy]

It doesn't need one it would be pointless imo

This is the one ive put in my N/a GT, its an OEM Gen3 4EFE rail & FPR from a very late spec JDM N/a. Doubt it will make any difference though lol.

Its different from the earlier ones, its got two diaphragms instead of one so guessing its a higher pressure ?

Comparing to the Gen2 rail & FPR

as above.all unneeded.

A couple of the German guys have cracked 100bhp and both use FPRs. Doubt it makes a difference but if you have a wideband and can tweak the fuel pressure to get your AFRs bang on then theres nothing wrong with that.

Thats a pulsation dampener, has nothing to do with fuel pressure.

Haha never had a proper look just fired it on. Have read the Glanza S & or Gen3 run a higher pressure do you know if thats true ?

Thanks for the input guys appreciated

Mine had one on it when i got it but jad no guage. Its still laying about in my room somewhere

Sorry no idea on pressure, maybe google the part number thats on the top of the reg.

Back in the day when we had zero money or less but still wanted to modify cars, we used to knock the top down on the stock fuel regs with a hammer to raise the line pressure. Down side is you can knock them too far or they can split if your not careful but it used to work.

I had one in my sr for a bit it was a rrfpr though pulled a bit harder low down but really needed setting up Properly so I pulled it off again as I was about to boost it anyway.
