You have done some serious modifications to the 1G-GZE engine and it could be any number of things causing those problems.
For a start how and why is your auto/steptronic connected to the GZE ECU ? Any 'false' signal/frequency etc out of the Toyota ECU could upset the BMW box, it won't be expecting signals from a Toyota ECU.
Rattle ? - mounting bolts and/or bracket ? Electric clutch worn out on the front on it - hard to tell going on what you have said and how you have modified it.
The GZE motor produces 9psi of boost in standard spec and you are getting 6psi ? Loss due to the intercooler ? BPV, throttle after the blower, its no wonder you are having problems with the set-up and are considering swapping it out for something else. Why a BPV on a lowly Toyota supercharged engine ?
To me, swapping stuff, until a 'miraculous cure' to your problems is discovered is just a waste of money. Fix it or find someone who can before you go making wholesale changes. If you are dead set on a swap, go back to the original BMW engine and s/c that......it might cure your steptronic problems for a start.
