I've read on some of the supra forums that one cannot find an exhaust housing to swap out the 1.32 ar stock housing for. I'm looking at one of these units (essentially a garrett GT4294 CHRA) for my project, but there is no way my 2 liters is going to be able to spin one of these @ 1.32 ar, even with the solid lifters.

Any input on if there is any place that has (or has a part number for) somewhere around a 1.0x a/r exhaust housing?

or am I just dead in the water with this whole idea

putting a smaller turbine and smaller housing is basic stuff for any good
turbo builder... but expensive.

at the other end of the spectrum...
Ive just had my T31 bored out to accept a P trim turbine wheel because
we determined that at over 4500 rpm my inefficient old school engine
was seeing a little too much back pressure.
like anything else there are more than one way to do it...
im sure someone has and will post another way for you..

half the fun of this is dreaming stuff up... and finding a way to making it work
