Fuel pressure regulator or fse boost valve?
Hi guys I'm a newbie on here and wondering if any one can point me in the right direction, I'm looking at getting a bit more from my impreza got a few sensible mods and am a bit puzzled about whether to buy a fuel pressure regulator or a fuel boost valve, the difference between them seems to be 1:1 ratio on the fpr or 1:7 ratio on the fse boost valve, and there seems to be mixed options on them both, can any one help me out? Cheers guys

You want a 1:1 regulator not a rising rate 1.7:1 one
Give whoever maps your Ecu an easier time with the fuel tables :) |

have you asked Duncan which he would prefer to map for you? He may have a particular brand that he likes so your mapper should be the first port of call.

first question is what is your current stage of tune? if standard then wont be needed.

I've now put a td05 20g turbo, full silicon hose kit including intake, all new oik breathers and vacuum pipes, new dump/recirc valve, yellow phase 2 440cc injectors, four branch manifold 3" full decat cobra exhaust system (heat wrapped from headers and Swan neck, turbo heat blanket, kept the hks induction kit, now looking at fpr/fse valves and fuel pumps and hoping when these are done to get an esl daughter board with a map from Duncan at racedynamix :-) .... Also have a 42mm race radiator in it too :-) |
Injectors are gonna max out way way before the turbo does, you wanna upgrade them first

I made 340bhp on 440's and standard fpr etc so should be ok as is

20G @320hp is slow, with lots of lag without the ''umpf'' up top.
meaning: you will want more real soon :D |

Lol 😁 I've just bought my first house so funds are limited until the new year.....I'm guna look into bigger injectors and fueling system in the new year, have you got any suggestions? 😀
Depends on what car. 550CC injectors will support +-400hp depending on the tuner/mods. They can be had very cheap from an STI with pink topfeeds, Or UDSM STI models with sidefeeds, are yellow 550cc.. Uprated fuelpump is a good investment. |
