Thanks Steve, I'll take a look on ebay.

I think the walbro 342 is better suited to a wrx. (the outlet pipe is on the opposite side to the 341). someone correct me if im wrong..

i cant find the seller i bought mine from sorry.

I found this one on ebay, It's saying the 341 is better suited for the WRX. Here is the link

Beware of 'Fake' walbro's being sold on ebay, they're coming out of china:

"The unit has a polished finish on the outside, whilst the originals have slightly rougher surface. The printing on the fakes are not totally nice to look at. Uneven embrossed logo and such... however, i suspect those are the earlier imitation units... now, they may have copied externally to about the same as the originals. The fake unit is unable to hold high fuel pressure during high flows.... eg. in a turbo car, when you reached 6k rpm while in full boost, the fuel pressure drops.

To be able to be sure you have purchased the genuine is to do a flow test. The fakes do not flow as much as the originals. Also the pressure test."

Vision R in O'connor sell the genuine ones pretty cheap.
