Are the drive shafts compatible from model to model. ie if you put an 87 diff in a 83 model, can you use the original 83 drive shafts. I know the shaft diameters increased later on, and they went from 4 bolt to 5 then 6 bolt, but did the splines that go into the diff change? Any help would be appreciated. Thanks

Yes you would need all the goodies. You have a 2.6 man, if it is maybe a .70 a/r with P trim wheel on a divided housing you should be ok as far as spool goes if your revving to 7k or so, probably full boost around 4k. That should be sick. Just be sure you want to spend this kind of money and that is what you want. A T66 is for somebody that wants to run 10s and have at least 500whp. If anything sell me the T66 cheap.

is it possible to go MPI with Magna, everything installed, including labor and stuff (my cousin would do it, he'll cut me a decent deal) for under a grand?  please someone tell me its possible.
