So far I'm really happy. I was running a hx40/35 with a 16cm housing that was producing 42lbs of boost. This turbo I'm running close to 50 lbs. It does not spool quite as fast as my hybrid, but once it starts building boost, it builds alot real fast. Drivability is awesome and it tows very nice even at high altitude. Exhaust temps are down 100-200 degrees depending on how you are driving the truck and they don't go up near as fast. With the hybrid I could peg 1600 degrees in no time, with this turbo I have to ring the trucks neck to hit 1400. Going from a stock hx35 I think you will 
the first time you drive it.
Let us know what you think.

You'll be a

I want to hear more on this one since you'll probably become a Boost junkie. Might have to stack this baby

So far no good guys. 
The waste gated version will not fit. I had to take the shock mount out to get the turbo in and then the actuator still rubbed the mount.
High Tech is shipping me a new non waste gated model and I'm shipping the waste gated one back.
So I'm still running the old 35.

Just got my HTB2 installed this morning and put 6 miles on it. It spools as good as my hybrid HX35 w/14 cm housing on the low end and builds max boost faster and higher than my PDR HX40. There's definately less smoke than with either Holset. Don't know about EGTs yet.
Paul at High Tech has modified the waste gate to be an inch shorter so that it clears the shock tower. It is also now adjustable. Mine is set at 38 lbs and easily hit that during the short test drive.
Hardest part of the install was building a down pipe. I didn't want to modify my HX40 pipe. But it would be easy to weld the turbo flange on a HX40 down pipe if you're looking for a quick easy way to do it.
I am impressed with this turbo!

Mine should be here mid week, I'm gonna use a 45* and weld the flange to that for my down pipe. I'm pretty sure it will work out okay.
Glad you're happy,

I'm into my down pipe about $32, including the 4" band clamp. The reason High Tech is expensive on their flange and band clamp is they haven't been able to find the parts anywhere else except Cummins. With the information I gave them today, that may change.

I'm gonna use the 45* with the flange welded to it then a band clamp to my 4" down pipe. Thanks for the info though, I wasn't quite sure if it was gonna work out or not. 
I have also found another place that carrys that flange and clamp, it's a little cheaper than the one HT sells to. I should have about $18 in my down pipe so it's not as big of a deal as I thought it was gonna be, just took a little work to find a 4" pipe supplier. 
Can't wait, gonna pull the truck this weekend so hopefully I can get the turbo on and a little breakin time under it's bearings before then.

I'm also curious to know if these turbos have been tested on a 12 valve. I noticed the website said they are for 24v and newer, but why cant you put one on a 12v? The last thing we need to do is to start discriminating!
