    T series engine question for toyota people

    I'm a Datsun fan but I've become quite fond of my automatic 3tc tt132 corona

    but its getting quite tired and I'm thinking of modernizing it.

    I've got some questions about the t series engines i wondered if someone could answer some questions for me?

    are the manifolds on 2tg and 3tgte's compatible?
    and can you use 2tg pistons in 3tgte's?


    I've been thinking i would like to source a 3tge, put some after market high compression pistons for a 2tg in it, and run it naturally aspirated.

    could i use the intake manifold and extractors from a 2tg?

    I'm not looking for an overly powerful engine. just something that will suit it and run nicely.


    do you think it would be worth sorting out a 3tc crank to increase the displacement?
    I'm thinking yes.

    i already have most manual conversion parts and i know of and am enquiring about a w50 gearbox and a 3tgte long block.

    thats about it.

    cheers

    My cousin's old TT104 (originally RT104) had a 3TG. Pretty sure it was a 3TGTE long motor rebuilt using 3TC pistons, custom cams and dual 40mm Solex's off a 2TG.
    There's also a few 3TC/2TG hybrids getting around, using a 2TG head on a 3TC block.

    different pin height NO

    2TG head is better than 3TGTE, normally aspirated

    could i use the intake manifold

    NO

    and extractors from a 2tg?

    YES

    for a 2TG YES

    I remember something way back about a 3Y crank will drop in a 2T block (albeit with a bit of meat carved out) to stroke it out to two litres.
    The downside being the 3Y crank is cast while a 2T-G is forged.

    Anyone else confirm this?
