A GT35R is pretty much a dual ball bearing version of a SC61. Even though the 2.4 will spool a turbo faster, you have to slightly offset potential RPMs that you are going to lose on the top end. The 2.0s rod ratio is pretty good and you can rev it quite high, most of the fast fast guys are running 2.0s and running high RPMs. The 2.4 rod ratio is quite poor, even the log rod versions are only slightly better. So you have to somewhat take that into consideration. For a lot of you that might not be a big deal, but I ran my ghetto half built 2.0l to 8500 almost daily and I would be scared to run a 2.4l out that far at all. Higher RPMs make for some nice long gears.

Guys are running 9s on turbo based on the wheel in the GT35R/SC61, etc. So it is quite capable. If you want it to spool fast then maybe just get a Mitsu version of it like the SCM61, if you want to make more power with it then get a T3 version of it and run a bigger exhaust side.
