boost2010

i just rememberd that the guy who sold me my car actually said its had uprated fuel injectors and may need a fuel regulator do you think this could be the cause of my boost issues ie not boosting properly trying to but just not right most of the time, sometimes its flying but most of the time its juddery and slowish. 93 wrx import

Cheap fuel regs are cheap for a reason, they are crap!

I'd prefer OE over that rubbish.

If you're going to do it, do it properly with an SX, fuel labs or aeromotive regulator.

Fuelab FTW!

I bought a brand new genuine 3-port from a US vendor on eBay - £109 inc. shipping!! But £30 import costs (i.e. £17 VAT and, get this... bloody Parcelforce fee of £13! WTF?!)

Still, £139 all in delivered for a brand new 3-port FL - how cool is that? Only took about a full working week to arrive too lol.

Unless its been mapped for the changes it will run crap.........

You cant just go changing bits, sounds like the guy that sold you it has had you.....

Here's a few more obvious questions that come to mind here than an FPR:
- was the fuel pump uprated at the same time as the injectors supposedly were?
- what kind of fuel are you running in it? If you're not already running Shell Vpower, try putting a couple of tanks of that through and see if it makes a difference.
- if the injectors really were uprated, just how much bigger are they? On a classic you should be able to identify most of the common available sizes from the colour.

Yes OP, find out all the stuff first that 172 and mark state.

Fuel reg prob only really needed to accurately control >/=550cc inj. and beyond >350bhp. A lot of people run big bhp on just the stock FPR (not advisable if an early Classic though, simply due to the FPR's age, if nothing else....)

joz,would fitting an uprated aftermarket fpr be unnecessary on a wrx running 280bhp as i have one in the shed,nearly new,i was thinking of using!??

joz8968

Well, if it's sitting doing nothing, then by all means fit it.... BUT... NOT if it's one of those £20-40 eBay specials! The FPR is a very important element and £20-40 is far too cheap (bearing in mind there's a also a meaningful profit margin in built in to the price anyway!!!). If it's a Fuelab, Aeromotive, Sard, SX, etc, then by all means fit it as it will actually WORK PROPERLY and is new, unlike your OEM original.

However, I'm currently running 282bhp on the stock FPR (17 years old!) - and my PFC Commander shows no dodgy IDC activity i.e. fuel startvation/oscillation, etc....

A pointless addition IMHO.

Your not going to gain anything by fitting it.

Your car should be mapped to the injectors its fitted with, you change anything such as fuel pressure, injector size etc etc then it will require further mapping tweeks....

joz8968

iTrader: (13)

Yeah, if you do decide to fit it, and even though it may be set to OEM 3bar (vac line off), then it would at least need checking on a RR for correct AFR's, etc.

No it didn't but I got a 7bar/100psi glycerine gauge from Temple Tuning.

If you offer $129.99 he'll accept (it's apparently the best he can do )

Looks like they're out of 'em. Don't worry though, do a search and there are others that sell that gauge, for a bit more...

milliemoo

how do you rate the fse adjustable type (i had it on my gtb).it has sytec on the side and it came from demon tweeks??

joz8968

iTrader: (13)

Heard too many horror stories re the FSE FPR on turbo cars! Don't take that chance!

BTW, that link above is just for a gauge. He's just added "FSE" as a marketing keyword - as the FSE "Power Valve" (FPR) is a common mod amongst the Nova and Saxo boys out there. So when they see "FSE" they go mad!....

Cheers for the link bud, there seems to be a few sellinjg from the states!

Hopefully seal an ebay deal soon and get it fitted!!

Yeah, there are quite a few. He has a really good shipping rate though, which was the clincher, as the delivered-into-the-UK price was the cheapest (by a little)...
