Re: 1987 300zx 2+2
1. Yes absolutely, this is possibly the most commonly asked question around here. From my own searches you'll need the following:
tranny (duh), mounts, drive shaft, possibly differential flange, a pedal, all the clutch hydraulics, torque converter to replace flywheel.
More detailed information on this swap can be found here:
Do further searches on here and also on z31.com for more information, but that's a good starter.

3. Forget about the TB until you're pushing serious HP because you wont notice anything until you're at that stage. The pathy manifold doesn't fit perfectly due to hood clearance and there's modifications needed for it to. Options are gutting the stock one, or getting a custom made one. Others on here who have done it (<http://www.88hybrid.com>) will be able to give you more info on that than I can.
Just know also, others will tell you to convert to turbo for serious HP. This might be wise before you go ahead and do all of the above. I have dumped alot of coin into my NA, and sure it hauls ass and top speed is amazing but as far as pickup and acceleration goes my turbo at 10psi just smokes my NA. Something to think about...
