Farrk me what a shit fight...here we go again.
JJay and Andrew, both w58 and r154 toyota gearboxes have there issues, and so do Rb25 gearboxes,It goes to how you treat them,(flat changing is not really good for any gearbox for that matter) not necessarily how much power you are putting in front of them BUT how much torque , you know the stuff that makes your engine twist when you blip the throttle on idle??
You can run way more than 400hp on a rb25 gearbox...Many of you may not know that they have the same bearing diameters as GTR gearboxes, but with less grip of a 4wd car they are quite strong in a rear wheel drive car.
A Rb25 gearbox is basically the same as a GTR box but without the transfer case.
The Toyota boxes aren't too bad either, but they tend to get a broken washer or shim in them which causes gearbox to jam, a factory fault i believe but makes it worse even with minor hp increases .
The Getrag 6 speed is the ducks nuts for toyotas, can withstand coupious amounts of torque and power, but once again how you treat it is a major factor.
So anyone going to the track day on saturday at willowbank? I am but not racing,
