All the following is for a T3 with the 4 bolts hubs. As far as I know the late models and early models 4 bolt brakes are the same.
The front and rear torsion bars are indexable just like the rears on a beetle. If I remember correctly one the bottom tube on a T3 has a torsion bar. The top just has a bar to hold it together.
The rear should be the same as a bug except the later ones had a larger torsion bar for the greater weight. If you need to upgrade to a larger diameter see Adrian's tech article on suspension.
The early 944 brakes with the steel arms will bolt right up. They only require an adapter for the emergency brake cable. I forget who sells one. The later brakes and turbo brakes rotors are considerable heavier and thicker. The rear caliper is nice as it bolts right up.
If you go with the single pots you will need the 944 MC as they require more fluid than four pots to engage the rotor.
Ah! The fronts. As far as I know the front rotor and caliper is the same as a Ghia. I know this as I am running the rotor and caliper off a T3 on Ghia spindles on my bug. I have also made two sets of brakes for other people using all Ghia parts and they look identical. The spindles are not interchangable with the bug. The CSP vented rotor should bolt right up to the T3 spindle. This matches the early 944 rotor in the rear. The biggest problem will be making an adapter for the caliper for the front. The machining will be quite tricky. It was a lot simplier for me to use a drum brake spindle. You might be able to do it by drilling the backing plate holes and tapping them to 8mm then using them to secure the adapter after you have cut off the mount for the stock calipers. Getting the proper dimensions was a bear.
This is some of what you will need to adapt the early brakes to the T3. The other posts above also apply. I upgraded to Wilwood four pots from the start so if I ran up the HP I wouldn't have to upgrade the brakes again.
Hope it helps.
