Looking to increase rear wheel torque for drifting any pointers would be great thanks you guys any other kind of modifications for drifting would be appreciated

 

Torque you can get with driving style. Keeping the revs up high is where all the torque is made. Short of FI there is no real easy way to help with that. Torque isn't this car's strong suit.

 

You can change the diff to better match the speed/size of circuit you're drifting. While it doesn't change the engine output, it can help you stay in the right powerband at the speed you're targeting. Otherwise even in stock form they're pretty easy to drift well, just clutch kick in 2nd (or 1st if you're at a slow track) and keep it pointed in the right direction. Oh and turn DSC off

 

If you want more torque do a 2jz swap lol. But for real though you could just throw some cheap tires on the rear so they can kick out easier.
