well the thing is that of what I know, supposedly the mini "S" are both turbo and compressor charged. I forgot what they called the setup, but all i got to say is that it works. Now on the supra, well I guess that is somewhat of an unchartered territory for all of us. I seriously don't think anyone here in the forums has tried it. its not a bad idea to add a small supercharger to build up the power while the turbo starts to spool but the route of the pipes is gonna be extremely confusing. Put it like this, if you got a pipe that is comming from the exit end of the intercooler to your intake manifold, where would the intake pipe from the supercharger go? that is what you got to consider if you are getting the idea of doing it. It is possible to mate the pipes together starting at the exit end of the intercooler and have the the discharge of the supercharger start there but come to think about it, you are gonna need an actuator to block the vacumm that would be produced from that so it won't disrupt the spool on the turbo. After that, you now have to figure out how that actuator is gonna open when the turbo goes to full spool. its preety complicated and its sounds like its gonna be very time demanding due to the fact that there would be allot of trial and error to go through. My opinion, leave your car turbo, its too much of a mission to accomplish especially if you are on a bugget (if you are). If you want to spool faster, get a ball bearing, it helps.
