ECU questions

i now got a 92 tsi all wheel drive engine,trans,and turbo unit, but now i need to put it in a 92 Gs w/ a 2.0L non-turbo engine, my question is since im making a block off for the transfere case (to convert the trans to a FWD turbo trans) will i need to use a GST or TSI FWD turbo ECU?

also i no im forgeting some things but other then the ecu, what other things do you need i will need to do to make this swap work out,

No difference in the FWD vs AWD ECUs, except for the speed limiter on the FWD at around 130 or so (since it came from the factory with lower speed rated tires).
