Without knowing the intimate details of the 2GR-FSE, for the N/A build I imagine he means:
Shot peened rods, balancing, shaving heads/ block, porting/polishing, notching the pistons (p-v), radical intake/exhaust, etc... Compression, moving more air, and shifting the curve to the right. The factory VVT mechanism may also me mechanically limited: I know on the k series honda motors they can be modified for pretty decent gains at various point in the power band.
That's pretty impressive though if another 90 BHP can be had without swapping cams (unless he's talking about re-grinds?), pistons, etc.
I think the link said the 4.0l N/A engine they offer peaks at 8,500 rpms... I bet every moving part in that thing is aftermarket.

On the other hand, IIRC those NA engines use individual TBs with a custom intake manifold, and there has to be a custom set of headers to go with that so they could do some wave tuning on both intake and exhaust. In conjunction with the remainder of the breathing mods, the ECU tuning, and probably race gas, I guess the claims aren't that far out there.
Unfortunately, for 99% of us driving street cars, none of those mods are very practical (if even possible on a street driven car) or cost effective.

I'm pretty sure Motec has released, or is soon to release, their M1 series which can handle direct injection. Motec has also indicated that a few people have been able to use their M800/880 with existing or aftermarket DI drivers...
Another Australian company, Adaptronic, also has a DI standalone that has been released or is about to be.
TrueStreet is right that these systems wind up being around $5k USD not including installation, tuning etc. and I imagine getting one to work with the factory electronics is not an easy task.

Is this the unit you are referring to?

that doesn't look like it has anything to drive the DI's.
These are DI driver systems, which still needs an ECU input.
