G,day, Ive been using my R33 GTST for superspints and drag racing, problem is my gearbox has stripped the case hardening of the gears, Ive been told that due to launching and prolonged high G high power (380ish killerwasps) loads the oil in the box gets pushed back and has starved the gears of oil thus damaging them, the oil was Hi-tec and changed every 5000k or so and was at the fill point..
Im going to buy a new box from just jap and want to know should I over fill the box a bit, Im also going to put in some Nulon SYN75W90 and Nulon G70 in it as well.
Unfortunatly I do not have the funds for dog boxs or stuff like that, my max cost is around $3000 for the box and oil and other stuff to get it installed.
Any help or info will be much appriciated.
Thanks, Mark
