I'm in the market for a new turbo right now and I'm having a hard time deciding on what size/brand. My truck is a daily driven 2004 RCSB with 6.0, FLT 4L80e, and Yank 3200. I have a Trick Performance Front Mount with a 3 inch down pipe. The current turbo is a Turbonetics 62-1 that came with the kit when I bought it. I want to keep the 3 inch down pipe, mainly because I don't want to ship the kit back to get modified and also I've heard a 4 inch down pipe is a tight fit. I want to make 500-600 rwhp with 10lbs and meth. So that brings me to my question.. What is the best turbo I can run with my 3 inch down pipe? I've been thinking about the GTK series but the one that fits a 3 inch down pipe is only a 66mm.. Is that too small? I've been told that a 76mm would be a great choice. I don't want to go cheap with this turbo and I would like it to be water cooled and oil cooled. Thanks

 

A TC76/78 is about your only chose then. Should bolt right in too. They're around a grand.

 

A few people have told me to go with a MP 76. And that turbonetics junk out a lot. But I have a turbonetics now and it's fine.. I guess junking out can happen to any of them.

 

x2 it can happen to any kit

 

I think i once heard Tnetics had a lot of problems with their non ball bearing turbos, which is now corrected.

 

if Wilde got a 5" Dp you can get 3.5 or 4" and it will help keep your underhood temps down a bit.

remember this is an air pump ANY restrictions will decrease output.

 

you can get a precision 76mm for a 3in downpipe i think.

 

For now I'm going to keep my 3 inch downpipe. And I'll probably end up going with the TC 78. Thanks guys
