After much research...
Check out this link for more information on the turbo debate. It's actually pretty good.

I contacted several people about turbos over the span of about 6 months. I finally decided on the B-1. I talked to HVAC about the B-1 (value his experience on the matter), Arron at Edge about his Pius modified H2e, and Al at PDR on the PDR 40. I also talked to several owners of each turbo and weighed it all out.
Each of these units have thier goods and bads. The H2e would've allowed me to keep my brake. The PDR 40 has good spooling characteristics and was a simpler installation. The B-1 flows more and is very tough. But they all had the downsides too. The PDR 40 was new at the time, and I don't like trying new products (remember the majestic debacle). Arron at Edge had hit the limit of his H2e and I had slightly more fueling than he did. Then there was the B-1. I had to make a new downpipe (righteous PITA cause I suck as a pipefitter), lost my brake, cost more, and lost some low end boost.
My decision to get this turbo was based on two things. First, I wanted EGT relief for the fueling I had. The B-1 seemed to provide the most. Second, I wanted this to be the last turbo I purchase. So I gave up a little to get this turbo. I knew what my fueling mods were going to get me into, and I did not want to screw around with twins.
Let me say this. This turbo may not be for everyone. Again, THIS TURBO MAY NOT BE FOR EVERYONE!!! I like the B-1 and am glad I got it. The increase in cruising EGT's aren't as horrific as I was told they'd be. Spooling, well, once you're moving it's a non-issue. But off the line it's kinda slow. But what do you expect from a big turbo. EGT's on the top end are down over 350*. So it does what I want well.
If you aren't going to throw tons of fuel into your engine, then this turbo probably won't work for you. You'd be better off with a PDR-40 (very good turbo) or 35, KS-35, AT-4, Pius H2e, or some other turbo. You need to decide what your application is (or is going to be) and decide on a turbo from that point. If you aren't going to go to Mega-mental injectors and you aren't going to sled pull, then you may not like this turbo. You'd be better suited for something else. Picking the right turbo, is more about final application and use than I first thought. Just my dos pesos.
