    Hi

    As the title says.
    Is this possible, putting the 1uz throttle body on a 3uz.
    Reason for this would of course be to have the cable operated throttle body instead of electronics.

    Have to find a new engine, as the 1uz I had bought turned out to be in a horrible state.

    Will be running Megasquirt ECU.

    Why not put a nicer aftermarket throttle body on if you are using an aftermarket throttle body? An early 1uz TB will need some adaption, a 1uz vvti TB bolts on but is still DBW even though it has a cable.

    What aftermarket TB would you suggest then? Was only considering the 1uz TB as I now have one lying around with no use of it :)

    Last 3uz I did with non stock Tb I used a 90mm aftermarket unit. I only did that as it was going to New Caledonia and i wasn't sure of their skills over there setting up the DBW if settings needed changing. Personally i like the stock 3uz unit. Sets up nicely with a good ecu. Fast operation and plenty of pedals which are available these days.

    Okay, ca see that it's nok hard to find a 90mm aftermarket TB. But are all bolt patterns universal?

    Just so much easier with the 1uz.... :)

    The universal aftermarket Throttle bodies (well over here anyway) come with a flange to adapt onto the engine. As you haven't stated which 1uz throttle body you have I dont know about bolt pattern. If you have a 1uz VVti DBW throttle body they do bolt on but still have electronics or if you have a Gen 1 or Gen 2 then they are a different pattern and would need an adaptor anyway. I did a video on youtube which might help



    Cheers
