8.8 IRS diff info required

[SEDUCE]

hey people just want to know what you guys think is stronger out of the Cobra 03-04 diff or the T-bird diff?
I am looking at putting either the Cobra aluminium diff or T-bird iron diff into my Drag car.
Its a RX7 full drag car but i want to keep the IRS but chainging to 8.8" and want the strongest diff i can get.
It is putting out 700 hp 38 psi now on run in tune and hoping for 900 full tune on 50 psi boost so need something strong.
Will be using a full spool and 4.5 gears in it.
Any info will be greatly appreciated.
thanks guys

Both rears will stand up to a ton of power.

However, the T-Bird diff, being cast iron, will most likely be less prone to case distortion, making it better for the purposes of a drag car IMO.
