Ah i thought you were changing your turbo aswell, he advised me to go with that cos there rated for up to 500 ft lb.
I will be keeping the 20g for a few months as the GT35-40 and exhaust kit comes to about 2.5k , need to save up more cash for that but at least it means my gearbox and clutch are good for when i go for it!
When your car going to be back on the road dunk?
