For engine management get one that you and your tuner are comfortable with, if people in your area tune microtech then get that
Lowering compression does lower power but your going to have a turbo so don't worry about that, if you can find pistons that will get you around 9.2-9.6 that would be great, 9.8 is a bit high for some tuners BUT if your tuner feels comfortable tuning a 9.8 CR turbo setup then go for it!
Ok .. Just to get started, what i think has to be done, to turbo it and not have problems, until i change all the other parts slowly is this..

Im thinking that is all thats required to run on 6 PSI .. ( before i was going to get a T28, is the T04E too big on 6 PSI or okay ? )
Please let me know if there is anything i have missed out that is definitly necessary..Or just your thoughts and ideas.. Thanks heaps
( What i mean by other parts is : changing the engine mounts, CV joints, strengthen first & second gear in gear box, Heavy duty clutch, change head gasket, etc... )
