First, we swapped the motor from a vg30e to a vg30de. The de provides a lot more power stock, and is a little better balanced. I didn't go with the tt for a few of my own reasons. I like the idea of an NA track car better than a tt, and I think that the de is going to provide more than enough power to be competitive with the weight of an old-school 200sx.
Our primary goal is to build a track going car at an affordable price, and while I have managed some of the smaller operations (like changing the diff or basic maitenence, I left the real work to the pros at SVS)
During the motorswap a few things happened, to fit the DE trans there had to be some banging around in the undercarriage of the car and it also requires a stronger trans mount. We've done it with a solid mount.
Now we also considered a few things to do while the motor was out of the car, primarily clutch and flywheel. I went with ACT package for about 900.
We also did the headers, I had mine sent from z motorsports but you may want to consider having them custom fab.
Intake and Exhaust custom fab from SVS performance.
The car came with a modified chip, a lot of JDM import companies will do this for you, so consider which one you are purchasing from and look around for the best deal.
Suspension was a s-13 front conversion and tien coilovers (you may want to check out megan racing I hear they have a setup that works a little better for this but isn't quite as beefy).
Sway bars, custom fab from SVS
Brakes are going to be cross-drilled slotted rotors, s14 front swap, and steel braided lines.
SVS is in the process of installing an SCCA legal roll cage, paint (think FC cinderella white on a red pinstripe at the base of the skirts).
For updates, uhm... follow this thread or me at Clubs12.org, Or somewhere else I go...

Point at which transmission mount won't work
These brakes will be removed in favor of the s14 front brakes (along with modifications described above)
