So jhaan_dude, sounds like you have found your way (or are on your way) to being on the 'inside' of the turbo parts community that is cloaked in secrecy these days. If you have the ability to produce these sleeper 16g turbos and other such things, that's awesome. Start a business and do it, way cool
They DO have a billet 50-trim setup, but it's based on the new-gen gt3076. That turbo by itself is nothing spectacular, but the HTA3076 is the same wheel that's in the FP evo red and is quite a performer.
The on topic turbo in this thread, the hta68 (hta16g if you will) this is a dream come true. I had SBR's bastard20g and loved it, but always loved the responsiveness of the small16g I had on the car prior to that. I got about 280whp @24psi w/ simple AFC tuning, stock cams, and a little bit of 111 mixed in the tank. 300whp@27psi (on LSE's DD dyno). I'd be willing to bet that a well setup DSM with a basic FMIC, hks272's, this turbo, and dsmlink would do 260-280whp w/o pushing the setup too hard on pump gas. Guess what, we're in 50-trim and gt3076 (kevin) territory on a stock-appearing turbo with the transient response and boost threshold of a 14b or s16g.
That my friends is HUGE. The powerband alone (3000-7000) would make anyone grin and the peak numbers are not too shabby....and while the power may not be 400whp, I'd be willing to bet that anyone willing to make the switch to E85 (lots of dsm'ers these days) or make the investment in an alky kit would see nearly that (400) pretty easily with the right setup. Shane tuned a 'regular' evo3 16g car to 350whp last summer with E85 IIRC.
