HKS or JUN cams are the way to go. With a T66, you will likely see more than 35 rhwp. Maybe up to 50 extra rear wheel horsies. And the reason why Crower cams are so much cheaper is: 1) they are in the US, and when HKS/JUN had a monopoly they could charge whatever they want, so Crower is more indicative of a realistic price and 2) From what I've heard, Crower should rate it's cams in a range. A lot of horror stories about bad precision. A lot cheaper, but I wouldn't trust them. HKS cams are fantastic, and are works of art.
Eliminate bottlenecks in order. After turbos/stock header, it's cams, then intake, then head. Upgrading restrictions out of order will be disappointing.
