T9 quaife, 3J, tracsport, etc strength

Hello All,

Been a while since Ive posted anything on here. Looking for a bit of info on how robust the t9 gearbox is when fitted with a straight cut gearkit? It would be fitted to my old volvo, which weighs approx 2700lbs. Would like capacity for 200ftlbs, 230hp. I currently have a t5 in it which is strong enough but was hoping for something around a 2.2 or 2.3:1 first gear which no one seems to offer for the t5. Any info and experience regarding the t9 strength, which gearkits seem to hold up the best, etc would be very helpful.
