JZX81Cresta

Hey guys i have a 1992 jzx81 project with a 1jz-ge novvti. I'm after some advice for tuning, the previous owner had got a stage 3 camgrind from Auckland cams and didn't do anything about the tuning. anyone have any idea what would need done to make it run good I.e. install a piggyback, adjustable cam gears Ect I don't wanna sped too much and I don't wanna go the turbo rout just yet would like the car running good so I can cruse around and ideas would be great cheers, Terry
