Style chooser

I thought TurboCharger only for manual, because autobox usually running on low rev, but there's turbocharged engine with autobox, can explain how it works with low rev? and how is the performance, (like hp loss, turbo lag etc)?

Other question....
I've done some research about mitsu engine, all i understand is the engine code, ex. 4G92 DOHC MIVEC, 4G63T DOHC, 4G91 DOHC etc... but i heard ppl usually call GSR, VR4, EVO 3, what engine code they are actually running?

Thanks...
