Would like to know from those who had this done..What difference did it make ? Was it worth $450 ?....Not interested in those who bought turbos already done....

As far as I know the only real difference is a little bit more tq in the mid range. I think you see a gain of 20ft lbs around 4500 ish but as far as peak power, I think they are pretty much the same. A lot of people feel that the difference isn't worth $450, but to be honest, it really depends on your goals for the car. If you have the money to spend and you want a nice circuit track car or a stop light to stop light killer, the HTA will probably be a good choice.

I would suggest looking over on evolutionm.net for more info. It seems there is a lot more users with experience with these turbos vs the DSM scene.

I know someone firsthand, dyno 598hp upgrading to the HTA. What he noticed was no more compressor surge in street driving. He did gain the little more hp and tq. This is on a 2.3.

On FPs site there are several dyno graphs Buschur made when swapping between a 35R and 35HTA at the upper limits of boost on his personal EVOVIII.
