    Turbo Choice with Aisin trans

    Hey guys/gals, seeing if anyone has run a combo close to this setup.

    I know how the 68RFE trucks run but my truck with the Aisin is uncharted waters for me.

    Anyways I am looking at running a s467.7 second gen swap, but I am unsure if I will be lagging a lot with the lower gearing of the Aisin or if I should drop to the S464.

    I will be staying stock fuel for a while until I get the trans built by Randy’s then maybe 100hp tips.

    Truck is my daily commuter, may tow heavy 2-3 times a year(15k lbs).

    Will also be doing studs springs and push rods at the same time.

    turbo specs
    s464 63.5mm compressor 74.3 turbine and a .90 ar t4
    or
    s467.7 67.7 compressor 83/74 turbine and a .90 ar t4

    What’s the overall goal for the truck?

    Are you just wanting some extra power or have a hp/build goal in mind?

    Just wanting some extra usable power.

    Big issue is how much the stock Aisin will take, guess I will find out shortly.

    Not a heavy foot driver and don't expect to race a 1 ton truck.

    I would like to have around 650rwhp which I think will be the top end of the s464.

    I would recommend the agree a 464 with your goals. There are a lot of people who will disagree and with this but I would say a 369sxe turbo would be a great fit as well. The 300 frame will spool up faster relative to the 400. With a T4 1.0 divided housing your drive pressure and EGTs should be in good shape with proper tuning. Power wise with a bunch of added fuel (relatively speaking) you can be well over 650.

    Are you wanting to do any transmission upgrades?

    The Aisin is a stout transmission but I would recommend having some kind of plan.
