In the Denver area, I'd call the following. I have used the first two many times and friends have used them all with 100% positive things to say. I suspect Crawlertech will be the least expensive but I'd call them to get a feel for how comfortable they are doing the turbo.

I am hearing more and more complaints about SFF Customs but have not used them.
Please avoid Bach Crawlers and probably Crazy Ed's if you value your money and peace of mind. I am not too familiar with the other guys down in the Springs though Serious Offroad and Predator and even Faricy Boys get mentioned. Sometimes it is more important to know which shops to avoid.
