Ok, but the strongest you can make a t-5 trans for every day driving (not a race set-up) would be to convert your trans to a z-box (world class). That's rated at 330 foot pounds of torque. 4-5k in parts will put you way over that power level!

But I guess don't worry about it till you get to that bridge.
Good Luck
