    Default Early V Late 4AGE Oil Pumps - interchangeable?

    Have cross-referenced part numbers in ToyoDIY but I'm still not sure. . .


    I have a 7/1988 build JDM AE92 FX-GT < early 7-rib big-port > and want to upgrade to later sine-wave oil-pump gearset.


    1. Can I retro-fit a post 5/1989 < Smallport > 4AGE oil pump to a 7/1988 < Bigport > block?

    And following on;

    2. Will this TODA gearset fit my BigPort Oil Pump casing or will I have to replace it with one from a later < post 5/1989 > 4AGE?

    all the complete pumps will physically bolt on to the block, but the gears dont always interchange due to small changes in the cases.

    Terry is right, you can't fit the TODA gears in what you have. The choice of pumps is the ones from the Silvertop 20V engines. This is what I offer on my site:



    I now have the TODA gears in stock too, but you don't need these if you're not going over 9000 revs.
