Yes, this a true NA-T conversion to the max. However, I would not recommend that others do the same. It's just too costly to build up an NA motor unless you're able to fund the project by selling parts or R&D as a result of the build-up. If had to do it all over again, I would have just done a TT swap; or, better yet, bought a Supra 6-speed.

For example, I have figured out how to completely pitch the distributor. I'm running HKS 264 cams, but it requires installation of Hall Sensors for cam and crank position. Additionally, I had to modification the AEM to convert it from Variable Reluctance (OEM cam/crank sensors) to Hall Effect. Converting to Hall sensors also requires sensor mounting which was done by machining magnets into an HKS cam gear (yet another expense just to ditch the distributor). Of course once the distributor is gone, I can then run coil packs. The good news is that it's a better ignition. The bad news is more cost.

I guess the better NA head choice is the VVT-i head. It has cam sensor mounts in the head, and it wouldn't be much trouble to convert distributor cam/crank to intake cam and crank sensor.

About the only thing that isn't more expensive than starting with a GTE motor is Dave Henry's intake plenum. I'm running his intake with a 4" TB, and it's about half the price of a VW intake/TB combination. Even then, if I had a GTE motor, I would have asked Dave to make one with TT intake runners. I still believe it would have cost less than Dana's intake.

So, anyone reading this thread, take note. If you're looking for big power and a platform that can be improved upon over time. DO NOT follow my approach unless you have a small fortune.
