hi, i,m in beenleigh, the 3rz have some issues (they break con rods), on toymocs there's a 2rz/3rz dedicated thread that is good for info. you can come have a look if you like or check it out on rides and projects ke38 wagon, very easy fit. in modified form the vvti doesn,t make as much power as the 3rz. check out the A.R.E silvia 760rw or LC engineering up to 1600rw but without spending$$$$$$$$ 400rw is easy with huge torque figures
