To put it simply, Yes It Can Be Done but will be a little difficult to setup. The parts come cheap but you'r gonna have to spend a lot of time gettin da required stuff and then tuning the damn thing.
I've done it and know wat hassles you have to go through inorder to do that. It costs nearly 15k but theres no-one whos gonna do it for you and you are gonna be on your own (except we guys on Pakwheels who can help u ).
So If you wanna do that, consider this that it'll give poor fuel economy......but goes upto 160 easily (its da max da gearbox can handle).
