I'm not sure if anyone makes a kit, I pieced mine together with a combination of parts from source automotive and crazy Carl's. Make sure to get a t-3 spacer and longer studs otherwise your compressor housing will hit the mani.
The manifold is a little wider, meaning the turbo mounting flange will be a bit farther from the head than a cast manifold. Also, it may be a couple degrees different as well, causing fitment issues.
I have a 2004. And can't decide what direction i want to go in. Either take my s366 and put a s480 over it or s467 or s475 these are three options im hung up on. What do yall say about each of these? Right now fueling mods are twin cp3's and 60% injectors with UDC. Fueling can change at anytime. Should I just try another single or go ahead and do twins.
I'd PM forum member LAmiller of Firepunk Diesel, they have been making custom compound kits for some time now and should be able to hook you up with anything you need.
