Fuel pressure regulators....

21st May 2011, 12:07

As you all know im buying all the bits i need for my throttle body conversion.

Now im looking at fuel pressure regulators, it is very beneficial having an adjustable version over the standard style regulators??

Looking at buying one of these....

Opinions needed.......

IMO I'd stick to a fixed FPR to try and keep the fuel pressure consistent over time and hence the map stays good over time and miles.

if your having it mapped properly that imo no, its just an extra expense. Do some maths based on your expected power output to get your cc requirements for injectors.

Most injectors are specced at about 3bar, so if the ones you have are a bit to close to what you calculated then maybe get a 3.5bar or 4bar fpr (there are calculators online that will work out your new flow rate at a higher pressure)

agree with the ablove, the adjustable ones seem to cause more crap then there worth and a decent wack more dosh, and if your on budget its just a waste,... unless your wonting it cos it looks nice in the bay?

Just stick with standard bosch ones mate, sure you can get 3, 3.5, and 4 bar ones.

i'd never have an adjustable one again and would just stick with a fixed rate 4bar regulator now

Stay standard and get a holder like mine

Its a webber unit i think (got it off danny) ill try and find something

You'd have to get the gauge to know what it was doing so you're looking at £170 on something that you can just get for pennies. if a 3 bar one isnt enough, swap it out for a 3.5, or a 4, total cost is going to be miles less.

A bit of expensive bling that isnt exactly needed.

Plenty of good engines/maps on fixed fprs.

Just use the Colin Satchell fpr holder, is perfect plus looks good

standard bosch items work great - we fit them basically to all set ups that are not using aeroquip type fittings, special fuel rails etc. and direct fit to stock rail, or billet holders.

as for adjustable - we ONLY sell turbosmart adjustable FPRs. cheaper ones are not worth the time of the day. fuel pressure is CRITICAL on injection cars (especially turbo) so dont take risks.

Hmmmmm standard style one it is then......just to work out if i need 3.5 or 4 bar.

Im running 3.5 on clio 182 injectors youll need no more

My holder on wing

failed at finding a link

I'd go 3.5 bar purely as they're on VTRs and some lesser models if you lift up the drivers side large grommet above tank

Haha little bling bling under te hood

and all good getting one with the kit your set haha bung in a 3.5 and away you go
Tbh unless your running cams ect i bet 3.0 (oem vts one) would do the trick as the duty on the inectors could be upped a bit to suit the more air or even just 306/182 injectors are a pretty proven way to go

I still think you need my spare 80mm high comps

HAha, what a good purchase that could be! 80mm wossners 708 cams get some ARP bolts maybe rods, then you are looking at something very tasty

I can get a veryyyyy good deal on pistons etc etc guys thanks to a very good friend of mine.

Alex please dont be offended but i only buy engine parts really brand new from the shops so if i have any issues i have a come back.
