3s-ge altezza fuel pump

[turbo tezza]

Hey guys, was just wondering what the standard fuel pump out of an Altezza will flow?

Reason i'm asking is that with the turbo on, and larger injectors coming, the fuel pump might not be able to supply enough. Don't really wanna upgrade if I don't have to at the moment.

Accurate figures would be nice, thanks.

Sorry I can't answer your question directly but I can offer a few observations:

The stock Altezza 3SGE fuel system has no return line, apparently flow is varied by adjusting the supply voltage to the pump. Unless you can map the supply voltage with the Power FC you could have problems; apologies if you already know this.

As a general rule Toyota seem to use fairly beefy fuel pumps, people in the US who have transplanted turbo engines into NA MR2s claim that the NA fuel pump has sufficient flow.

I'm currently running a gen III 3SGTE on a VVTi 3SGE pump in my MR2 and it appears to be fine; I am planning to dyno verify the A/F ratio before I seriously thrash it though. I would recommend you do the same.

Thanks nem,

The power fc is specifically for the altezza turbo, so i would think the guys at apexi would know about the supply voltage to the fuel pump.
