It looks like the same trans in the Imp for both the G200 and the Turbo motor, but I'll have to look in more detail through my Impulse parts book. If I find any gotchas I'll let you know. If the 5Spd you are looking to use comes from a truck it might be different, but should not prevent you from getting it to work. Like rezkid said, just find the right mix of clutch parts and you'll be good. The 4Z*1 line of motors will not interchange flywheels with the G200 and G180, so clutch parts should be largely picked from the 4Z stuff, just FYI. There is two more bolts on the 4Z flywheel than the G Motors.
