tDR Posted August 24, 2007 Share Posted August 24, 2007 I'm sure there was a thread with some testing done and with increased voltage like for like vs the larger Toyota pump, the walbro outperformed it. The walbro can be had for £60... Cheers, Brian. Quote Link to comment Share on other sites More sharing options...
michael Posted August 24, 2007 Share Posted August 24, 2007 Walbro GSS341 (not sure how different this flows to the GSS342 if at all) @ 13.5v @ 43psi - 262 lph OEM UK/US Denso @ 13.5v @ 43psi - 277 lph (290 lph @ 14v) (GSS342 is J-Spec fittings, 341 is UK) If you go up to 16v on the UK and 16.5 on the Walbro then the Walbro seems to flow more at higher line pressures: Not a huge difference between the two and as the lovely Mr tDR states the Walbro is cheaper... I'd still go for OEM though unless I was unable to feed my family and needed the money. Quote Link to comment Share on other sites More sharing options...
tDR Posted August 24, 2007 Share Posted August 24, 2007 Is the broken image above the comaprison graph that used be kicking about michael? On your stats, the larger Toyota / Denso pump does appear to be the better performer and tbh based on that I would go for it if it wasn't for the fact it's £100 more from a cheap source such as Nic (god knows what Toyota want for it!). I don't see it as good value considering the Walbro is very close in performance and you'd need 2x of either regardless if you wanna go above T67 (which one Walbro is proven to happily support) kinda size turbo wise. Maybe I'm just tight Cheers, Brian. Quote Link to comment Share on other sites More sharing options...
michael Posted August 24, 2007 Share Posted August 24, 2007 Ah, it's not broken here, I'll attach it... As you say the price difference vs performance means the Walbro is the sensible choice and it's still more than capable of doing what it needs to do.

hadyn Posted August 24, 2007 Author Share Posted August 24, 2007 As I asked above, does the uk spec pump wire into the j-spec pump harness with no modification? How much bodging do you have to do to the j-spec cradle for the uk spec pump to fit? Quote Link to comment Share on other sites More sharing options...
michael Posted August 24, 2007 Share Posted August 24, 2007 I seem to recall a thread on here where a J-Spec owner bought the Walbro GSS341 in error, that contained the info you crave... I just can't to find it now. Quote Link to comment Share on other sites More sharing options...
