i was looking at the t-56 and have been told to stay away from them (even with 26 spline input shaft) when they get around 700hp they can still break
as for the IRS if your into drag racing id stay FAR away..but if not get a IRS brace and new derlin bushings. if its a 01 IRS make sure you upgrade your halfshafts to 03/04 01's have 28 spline shafts while the 03/04 have 31 spline
and if you do get a 01 4v do it right and get the cams best for what you want to do with the car (comp stg 1-3 or custom grind etc..) dont waste money to go back and redo everything. might be a wise move to have the motor built before throwing it in also

with a twin disk they will last easily... but if its going to be a bolt on 4v car overall power handling of the t56 is irrelavant.
also 01 irs have 31 spline axles, but they have crappier inner cv joints, and they dont have the diff brace that goes on the front under the differential...

"...
a) How much bracing needs to be done on a 99-01 IRS(planning for the worst possible scenario..I will be going with a 03-04 if possible) with the motor mods I have planned? There will be full bolt ons on the car of course. I am thinking 4.30 gears for sure, especially with a higher reving 4v.
b) Typical t56 cost is around what 3k with all the parts(not including labor)?

As for T-56 swap, I spent around $3500 and another $500 to help my buddy install it at his shoppe. That included new Pro50 shifter, alum. DS, cross-brace and everything. Was well worth the swap to me, but be sure to research the gearing as there are several ratios available.

Why are you planning an IRS swap? You will do better with a built SRA on AX and 1/4
