This is a PM that I received from Matt. Excuse my ignorance but I'm not sure what a ST165 is, is that something off of a Celica?

However, if you use the st165 DP, stock or otherwise, you'll have to use the st165 manifold, as the manifold angles the turbo slightly different than the mr2 one, and the st165 dp compensates for that. aside from all that, you'll have to pull the compressor and turbine housing off, pull out the locating pins, and then clock the housings and center section accordingly. after that, I cut and threaded an mr2 wastegate actuator rod, and used an adjusting nut on it, so that it works correctly. I think that was pretty much it.

let me know if you have any more questions.
