Sorry, I guess I read it wrong. You're not going to get the HP you are expecting converting the turbo engine. The plenum of the turbo engine places the carb over the drivers valve cover for those that don't know. I can see your problem. I thought you were having hood clearance trouble but if I had paid attention to the Jeep part, I would have figured it out.
I have seen cares made in the 30's - 60's that have been modified to power brakes. They have a smaller booster than many of the 70's and such cars. You could look for a smaller booster and master than the one in your Jeep and go that way. You could make new motor mounts and move the engine but then again I can't picture the magnitude of your problem.
The 231 is a peppy little engine even without the turbo. TA has everything you would need but it will cost and you will need to go internal to squeeze the hp out of it. You could also go with nitrous. The bottom end of the turbo engine will handle that. It's manufactured to.
Good luck! Keep us informed. Any turbo parts left over could help defray your cost. There is a market, how ever small, but there.
