How much does the stock fuel pump flow?

[Terrh]

I searched for this and can't find this info anywhere..

does someone have a flow chart for the stock 7M-GTE fuel pump?
Wondering how much horsepower it'll support, and if the stock R32 skyline GTR pump I've got laying around is worth putting in or not. It's rated for 240LPH, and seemed to serve me well in the ~450whp range in the skyline. I've got dual 255's for it so I figure maybe it'll live a second life in my MK3.

Anyways - if anyone knows what LPH the stock pump flows, or a ballpark on how much horsepower can be safely made with one, I'd appreciate it.

ball park 300 hp. but its a old pump its just insurance to replace it especially if going for hp.

I have a skyline pump in my supra.

...well, a q45 pump, but it's identical.

I'd swap it, as the stock supra pump doesn't flow that much, I can assure you of that.

Dunno if it helps but the factory test spec is a minimum of one liter in 30 seconds.


Alloy: Wise decision....the Delorean thing was a bad idea.

...would've been awesome if the guy didn't want almost 4 grand for a burned shell.

That's a minimum rate...pretty sure it flows more than that.

Here's a FP upgrade guide on MKIV.com:
