    Default 4age fuel pump for 4agze

    hi guys,
    would the stock ae92 4age small port fuel pump supply enough fuel for the 4agze?

    thanks

    I am unsure of specs but i'd imagine you should be able to run a stock gze on the pump your talking about. However i would be seriously considering getting it upgraded cause you dont wanna have your motor lean out and shit itself for the sake of $300 bucks max for a bigger pump.
    Do some research on the net and find out how much a stock gze pump can flow and how much a stock corolla pump can flow and compare the difference. Either that or ring repco and ask for a replacement corolla pump and get the model number for a bosch one, that should make finding flow volume easier.
    A friend of mine had a 1jz in a cressida running on a stock pump and it was fine. He's a little dodgier than i am and in my opinion i'd buy a bigger pump. It will be one thing less you'll have to worry about either playing up or should your engine have problems youll know it wont be the pump - provided you set it up right.

    Google should be able to find your answers

    Yes, my stock smallport pump fueled my GZE with a 164mm pulley for many years with no issue whatsoever.

    The consensus on Twincam.org is also that you can fuel a GZE easily with a smallport fuelpump.

    If you would like to upgrade suitable Walbro fuel pumps are available for about 170$ on ebay

    I have heard the same thing. The only difference is how much toyota charges you. I went to get some prices for my MR2. A non-sc was about $300, the sc was $900. I didn't buy either...

    I then went to repco or some other auto store and bought a pump made by a different company. Still had the same part no. though. It cost me $250 which was still a rip off . My GZE has been running fine for that last year and a half since I put that fuel pump in

    Just checked my EPC on the Jap area cd's and the 4AGE and 4AGZE's have different part numbers.

    Even the late model AE92 GZE and the AE101 GZE had different part numbers.

    However, I too am using a AE92 MAP 4AGZE with a 4AFE fuel pump, it runs a tad lean down low and hella rich up high according to the dyno. If I nail it in 3rd it will give off a single audible ping down low, same with changing gears.

    Contemplating a fix.

    I'm pulling 130kW at the wheels on a ZE with a standard NA mr2 pump with no issues.
