That's perfect!

Is the Walbro 255 lph fuel pump the good one, i can't remember exactly but i was reading up on fuel pumps and there was one that people recommended but then a review was done and showed that it wasn't so good and to use a better one.

What BHP would this fuel pump be good for?

Thanks

Walbro 255 will be OK up to 450bhp(i've seen few at 500bhp).Out here is on eBay few non genuine Fuel pump,which seems are worse than others,but i've run cheap eBay fuel pump on mine without the problem at 350bhp,HRC fuel pump are good and i'm now using HRC 340 lph,good price too.

My car is 447hp using a walbro 255, what do you recommend I change to if I want to push beyond 450hp?

Cheers, TX.

Depends on more factors(injectors,Boost,Fuel pressure),but still think will be OK with this bhp for sure and beyond as i said depends on more factors.

I'm using HRC 340 with Bosch 044(from reports is noisy),due i'm considering Swirl pot in near future.

Walbro rating for 255LPH is 550whp,but i'm not sure if its handle this power.
Here is good article/test about this

I don't sell crap and if I give you good advice I won't spoil it with rubbish parts.

We fit the Walbro GS341, 342 and 343 as appropriate. In our experience these are good on cars running to around 430 bhp and not beyond 450 bhp max. Beyond the Walbro we would fit an alternative pump subject to the spec of the car in question. This includes Bosch but be careful because there is a 6 Bar Bosch that flows no more than the Walbro and a Bosch Motorsport pump variously rated at 8 and 10 Bar. These are expensive pumps.
Fitting a bigger pump beyond the Walbro and we would advise heavier power cable and a relay.
Generally we set the pumps at 3 to 3.1 bar with the vacuum pipe disconnected and we refer to fuel pressure as "x" bar over boost. Therefore, with a pump set at 3 bar static running 1.8 bar we expect to see 4.8 bar fuel pressure. 3 bar over boost. 1.5 bar boost pressure and we expect to see 4.5 bar, 3 bar over boost. and 2 bar boost we expect to see 5 bar fuel pressure. ie. 3 bar over boost.
Not many cars have an in cabin fuel pressure guage but it is a very useful way of determining whether the fuel pump is up to the job or not.
I had an example recently on one of my own cars fitted with an uprated pump (not Walbro) and GT30 turbo. Beyond 6K rpm AFRs were getting weak. I suspected it could not be the fuel pump and fitting heavier duty wiring cured the problem.

Not sure about subaru's, but in the past I have fitted two pumps and a swirl pot for big power cars. You can get a set up with non retrun valves and larger lines for less pressure drop. Walbro pumps are very reliable. At higher power levels its allways best to al least monitor the fuel pressure, if possible monitor the pressure differential from boost to fuel.

I'm hoping for 300BHP if possible?

Thanks

300 bhp and not changing turbo or injectors is not big power and fitting anything other than a 255 lph Walbro would be an unnecessary waste of money and an unnecessary complication.

By running a full decat system including ported headers and up pipe and an EcuTek remap, without a Walbro 255 lph fuel pump, will power be restricted, what's the risk of running a standard pump?

Thanks

That was an article comparing MY06+ fuel pumps against the Walbro. I forget where it's located. In any case not applicable in your case

Also why with the simtek ?

Could buy a nice new Andy Forrest TD0516g hybrid some injectors and an ecutek remap for the same money as an ALS Simtek

Your car is 11 years old. Your fuel pump is probably tired. Fitting a Walbro 255 lph pump is to give safety to your engine and nothing else. The cost of the pump is £75 or thereabouts, complete with fitting kit or £100 fitted here and it would be foolish to look to extract more power without dealing with a potential weakness ie. the OE 11 year old fuel pump.

What can the standard Turbo 2000 TMIC handle?

Thanks

Hi mate, I have a UK2000 on an X reg.

I have a VF35 Turbo, FMIC, Walbro pump, sports cat system (not full decat) and CAI kit. It was ECUtek remapped by Zen and produces 337bhp/300lb/ft on standard internals and injectors. Been run like this for 20,000 miles.

Dont forget that if you're looking to mod it you'll need an ECUtek remap @ £550 unless its been done already and just needs tweeking.

If you plan to run the standard fuel pump (god knows why!) then be prepared to limit performance or get fuel starvation. One of the cheapest/safest mods is to upgrade to a Walbro pump, its a no brainer.

I would have thought he would have 380cc injectors-- classic wrx wagons had the TD04 and 380s -- they made what, 230bhp standard? similar to a late classic Turbo 2000 right?
