hey guys. Heres the rundown of it all.

The mani-turbo bolt patterns are both the same, but the supra turbine side uses a round inlet and the mr2 manifold is a divided square. For this I knife edged the manifold divider, and sort of squared the inlet of the turbine housing. This probably isn't needed, but I'm sure it helps.

As far as clocking, you just pull the housings off, find the little roll pin on each side, pull it out, and the housings will clock pretty much any direction, aside from the wastegate problems. For the wastegate, I used the mr2 canister, (used an upgraded mr2 compressor, so it bolted right to the housing). I had to bend the mounting tabs a little, and cut the actuator rod, and tap it for an adjusting nut, to get the right amount of preload.

As far as a downpipe goes, I made my own 3 inch divorced DP. The turbine outlet is a different bolt pattern, so the mr2 ct26 DPs won't work.

You could also use a st165 manifold and DP, but I'm not 100 positive that the 165 DP outlet is in the same spot.Dunno.

hope that helps
