Boobee. The reason I was asking turbo/engine combo is that (and this is my opinion only) the taller gears in the OS set make a lethargic bottom end of a 2.6 L engine and make it even more pronounced.
For example, a mate on here on a pretty decent R33 GTR put one in and ended pulling it out and going back to stock ratios. That was predominately a track car too. 2.6 with -9's and -5's at different points.
Just something to think about.
Bakemono. Cheers man . Be good to drive it again lol.
