Dose any one have some specifications on these?
I am turboing the supra and wondering if this pump will keep up with the demand.
Thanks.

"turboing"
what sort of engine, and what sort of hp are you looking to get?
stock 7m-gte will be fine with stock fuel pump. heavily worked 2jz might not be so fine

Stock pump will "probably" be ok but a Walbro is cheap insurance. $100 or so and it's good for up to 500hp.

FYI my stock pump powered my 1uz fine.
Put a Walbro in there and it was running that rich that the o2 sensor on the dyno couldn't register it.
It was running about 9:1 at idle!
Looks like the stock pump couldn't handle the pressure.

yeah as has been pointed out a fuel pressure guage while on a dyno/driving around will be able to tell you if it is pumping enough. if the motor starts using close to the limit of the pumps capacity your fuel pressure will start dropping.(ofcourse there can be other variables)

Thanks guys,
I will tap a pressure guage into the rail and see how it goes then.
Walbro pumps seem pretty popular then.
