Not comparing.. but the power delivery is alot different is what I meant... at the end of the day the HP difference between the two is what around 100HP depending upon what rear housing is used?
My lil old GT35R made 350rwkw before the cat and exhaust limitations were reached. Turbo may have had more in it, but Il never know. The T04Z was sitting there so I decided to change over.
They are alot better (few secs each track thus far), but we have changed the suspension setup and a couple of other things at the same time, so I can't compare based on just the turbo swap . Although I am losing alot less boost between gear changes with the T04Z than with the GT35R... everyone that has driven the car in both forms has commented on how noticeable the difference is.
