Im starting a new build here on my 01 Sierra C3. IT's setup just like the Denali trucks 6.0/AWD Denali front end

So far I have a Borg Warner S480 T6 with the race cover, twin 44mm Tial wastegates, and a 50mm Blow off valve.

I was going to go with a trick or Kb manifold but decided to just make my own. Going with a 3" log manifold out of schedule 10 stainless and 1/2" flanges

My only concern right now is the down pipe/turbo is gonna be right on top of the ac line. What have you guys done to get around this? Im sure going with a t4 would be much easier since the downpipe is so much smaller.

Lets hear your thoughts. Im gonna use 2.5" stainless from the drivers side manifold to the passenger manifold.

 

You will have to get custom ac lines made. Your building a big power setup...whats your engine consist of? And why t6?

 

I already own the turbo so I figured I would use it. The only thing I plan on doing to the engine is valve springs and head studs

 

A local place called Stuart Hose and Pipe Co in Fort Worth can make up anything you need. I'm sure there are others like them in your area.

 

You dont really need new lines, you can bend yours out of the way. I have pretty much the same thing you are going to build except mine is a regular cab. Either the Trick mabifold or KB Racing manifold will work for you if you want to purchase one. That T6 that Trick makes looks very nice and already is setup for the wastegate.

You do want at least 1 inch of clearance between your AC line and the wrap on the pipe

 

Trick's t6 isnt available until end of december and If i spend a fair amount of money on a manifold i want it tig welded so thats why i decided to build my own. I ordered a bunch of stuff from Ace Stainless. i figure on 8-10 psi it should be a fun daily driver

 

Post plenty of pics!!!

 

What size turbine do you have and what year did you buy it in?

I assume you have a 92 mm (most guys buy that T6 turbo). If you have an 83 or an 87 you can get a T4 housing.

 

96mm turbine with 1.32

 

Still waiting on some parts, changed my mind on the turbo. Ended up selling the S480 and ordered a 7875 t4 turbo
