I was looking at the ats website and looked at the numbers of the 1-5000 turbos and i think the 3k will be best suited for what i want to do and what not, but i didnt see any prices. I also here a lot of you guys running the 62-64-66's but i couldnt find to many websites on them. if any of you guys have somewhere with good pricing that i can look into that would be helpful, also if you guys have some real world numbers with any of the turbos mentioned above that would be equally as helpful.
