So what is the 3794 exhaust side. If a 68 stg2 r is a 68/68.

Then he now has a 68/71, Wonder what the exhaust size is on the 3794... 66?
Yes, 66mm turbine in the 3794va's. The 71 is intended for guys looking for the extra topend power as it is worth another 40hp over the 68mm turbine when combined on a 68comp wheel max effort. Touch less down low compared to the 68mm turbine but better mid and topend power. None of them will keep up with the 66mm down low period.
