In my hours of research, they seem to be very popular in Singapore/Malaysia with a bit of a community going on. However, still quite limited. Fortunately, that means local Malaysian workshops are making some parts. My family is originally from Malaysia, so I could always hook up delivery etc.
Now if we're comparing stock against stock 7psi etc etc
Track itd handle quite well, corners better than the legnum, straight itd be close but the legnum has the torque to pick straight up
Keep in mind its a 4speed auto, but the auto shifts alot quicker and better than our car and final gear sits about 2000rpm at 100km/h veryy nice! But i have gotten my friend to search on gearboxes see what they can handle with no luck ( which is good)
Though sometime late next week I'll be installing an electronic boost controller and winde it up to 14psi and see how itll go, i reckon it should be very impressive as i know the 3sgte is good beans
All in all track should be good, brakes arent too bad for standard, but id probably look at a transmission cooler just for the peace of mind, only the foothandbrake may throw you off! Haha
