I have a question regarding the ihi rhb52 turbo tat I want to use. The turbo is off of my ford turbocoupe it is the largest compressor wheel equipped rhb5 turbo that I can find. I am also aware that these turbos came in many different automobiles. I am not worried about using the compressor as I am about the a/r of the turbine. I want this to spool similar to a t23 .48 .42. My turbo is in good shape. I want to run to 16psi on the motor which has been fully rebuilt and has vitara pistons. My question is what turbocharger out of another rhb5 equipped vehicle can I pirate the turbine housing out of, so that I can hybrid this turbo to spool sooner, that is if you guys think that I should even bother. I was considering a subaru or probe or impulse rs housing could you please tell me what will work

Any one of those should do the trick.
You'll probably find the smallest exh. housing on a I Mark 1.5 8V turbo.

I also have a Turbocoupe (IHI equiped). If I remember the IHI had an exhaust A/R of .58 and the T3 models got the .63 A/R.

The RHF5 is the closest map to the stock RHB5 of the Turbocoupe.

If I recall, the numbers are cast into the housings, but are metric.

The T-coupe T3 is .60/.63, might spool around 4000 if ya bolted two G10's together!
