There are 3 engine variants for the Altezza
2L 4 cyl 3SGE @154kw (6 speed manual) or 150kw (auto)
2L 6 cyl 1GFE @118kw manual or auto
3L 6 cyl 2JZGE @162kw 5 speed tipronic auto only (or 4 speed in AWD models)
I have owned an RS200 2L 4 cyl 6 speed and currently own an AS300 Gita 3L; they are very very different cars but IMO the 2JZGE suits the car better, auto notwithstanding. I sold the RS200, I don't think I will ever sell the Gita. If you wanted a base for a serious performance car, rather than a sports sedan/wagon, then the RS200 6 speed would be a better base, but not as good as an MR2 turbo
