    Default 1988 TC single Holset turbo 5.0/ 4R70W

    Hey guys. I've been doing this build for a while, but thought I'd relate some progress.

    The car is a real nice 88TC I bought in pieces. Dash out, engine, trans, fuel tank, most everything off the car except the rear end and trunk lid. I towed it home with MANY boxes of parts and it has sat here for a few years.

    Recently I bought a 4R70W OD trans for it and an Explorer engine for a donor. The engine ended up needing too much, so I went with a rebuilt 87 'stang long block, using the accessories and intake from the Explorer.

    Picked up a Holset 351VGT turbo and a set of BBK shorties and went to work.

    Prepping pan for turbo drains, checking bottom end, and bolting on transmission. I had to swap the transmission rear extension for one off an AOD to accept my driveshaft.

    Swung in the engine and checked fit of the Explorer radiator and NPR IC.

    I didn't have the correct trans crossmember so I modified the Tbird one to fit. The exhaust will be a single 3" coming down the passenger side.

    Next I found a spot for the BIG honkin' turbo, and made a cut or three.

    Then started on the hotside fab. I had a lot of problems getting any kind of decent welds, so don't give me too much grief!

    More fab shots, and the turbo brace. I'm going to reinforce the brace a bit more.
