WRX WALBRO fuel pump install into EVO - easy
The WRX walbro 225 lph fuel pump is a direct no mod bolt into the stock fuel pump location - - anyone running up near 300 wheel HP is going to run out of fuel - - this pump give you up to 400 wheel HP capacity with a bolt in item - works perfect and its cheap !

How come Buschur is making 350 to the wheels on a stock eveo and still has plebty of fuel? I don't see this mod being necessary on a stock turbo evo, maybe with a BIG turbo.

Finally - dosnt Buscher tune at 12.5 a/f ratios or something lean like that >>>/?? I keep my a/f at 11.2 - 11.4 so I need more fuel than some

Hi, the Walbro fuel pump used is for 02+ WRX or earlier? Is there any URL that we can order online directly from.
Thanks.

You A/F gauge is usless, but is pretty and nice to look at. BUT Buschur tunes cars rather rich and picked up 30WHP on teh Dyon with one, like NIGHT and DAY. The stock pump is atLEAST a 195LPH, probably bigger with the noise it makes and the power it makes while still being rich as all.

ALSO, if you put a bigger pump on, the stock FPR will more then likely not be able to return the fuel back to the tank, it is TINY, so it will back up, and raise the base fule pressure which will cause the car to run like ****.

So are you saying your seeing a pressure drop at higher rpm with the power your making?

Also - for someone who wants something totally quiet - - PE just relesed a new PE 255 lph pump that will alsofit right in (too rich in $ for my blood - I'll take the very slight noise in the trunk)

BTW, it isn't a WRX part number from Walbro. This pump fits in many different cars. I sell them as well. Make sure you are getting the high pressure 255Lph model. It is GSS342.
Buschur is quoting 2 wheel dyno numbers which may be slightly higher than 4 wheel dyno numbers. But we won't get into the whole dyno comparison thing. Just change the pump when you get to that level; it's important insurance.
