I was just thinking about the 1g-gte - I know they aren't that great but they have a twin turbo setup on a 2L - would it be possible to use a similar sized turbo, even the same CT12's(Could probably use the CT12A's off a 1J) on an RB20 with the right amount of custom work?? I'm not too familiar with how quickly they spool so don't know how laggy they are.. I think there were two power outputs for the engine(185hp & 210hp I think...), but I am not sure how much power they(turbo's) will handle..
