R33 I've read is better box I can't remember why. There a great box will take 600 hp and abuse no problems as long as not a million miles old knacker box

I have run in the low 7 seconds to 100 mph on vredestein tyres no problems they are a tough box for the money, I'd want a getrag 6 speed now though if I had another there so much better imo and worth the expense
