Attention: TDR Forum Junkies 
I guess I can finally say that my truck is up and running again.
I'm running with an H2E turbo and a marine cam.
These are just my opinions, but I wouldn't recommend either one.
The turbo is just too big for street use. Pulling is definately not an option anymore. You would think that the huge turbo would reduce EGT on the topend, but I honestly haven't seen it. It has the 17 cm housing not a tiny restrictive 12 or 14. I pegged the digital gauge at 1747° by 50 mph from a standing start. This is the first turbo that doesn't clean up smoke. The other two turbos I've tried would smoke down low, but the smoke would clean up once the turbo spooled. This thing smokes anytime the boost is above 20. As you add fuel to make more boost it just smokes more. I have enough fuel to push it to 46 psi and the smoke never clears up. It's just WAY to big to be used as a single turbo IMO.
The cam is equally unimpressive or maybe it is the cause for making the H2E look so bad. I try to drive around without smoking out everyone around me. If I hold the throttle at a constant fueling rate, the truck will accelerate without smoke until 25-2600 rpm. After that the smoke begins to get thicker and thicker. It seems as if the cam doesn't breathe well above 2500 rpm.
These two modifications didn't increase power enough to be noticeable. It honestly might have lost power.
As far as airflow goes. I've got a fresh three angle valve job. Ported head from Piers. New pistons/rings. 4" exhaust. Marine cam. H2E turbo. And there's just not enough air getting into the motor to make any serious power.
My stock motor with 150,000 miles and only fueling modifications would walk away from this truck.

I honestly do not see how you could make and sell a cam from a rough forged blank for $360, and billet would be triple easily with the volume we are talking about. It would scare me... .....
