Red,
That's Charles that built those for his own truck. The guy is pretty bright and definitely did his homework and ended up with a great set of twins.

cchase,
I have a bunch of pics on my site in the link above of everything you need to know to build twins. What else do you need to know or are confused about? Don't complicate things, it's actually pretty easy once you get a grasp on what's involved. The hard part is making it all fit under the hood. (aside from the previously mentioned 'Hard Part' of making the 2 work well together.)

GTS,
Just like you said that you don't need custom programming to run custom injectors, I could say that any turbo that flows more air than the stock turbo will work for a twin set up. It might not be optimum, but it'll be better than a single. Even with my cheap, crappy HT3B feeding my stock turbo, the difference was amazing and quit fun to drive. The HT3B only flows like 1000 cfm, the 38R, I was told, is a hair more than that. :dunno: Haven't confirmed it, though everyone that has one that I've talked with gain about 100 hp with it so I'm guessing it moves some air...

yea ive talked with him a couple of times through pm on youtube and seen all his pictures i could tell he knew what he was doing just by his pictures
 
I am thining about stacking a gt35r and something like a gt42 or a t6 because i am a sick person. But my personal goal is to humble a friend of mine and his stacked up jacked up dodge on toyo 40's running 3 chips and a hybrid 70mm turbo. I mean thats just sick... its still a dodge!
 
Does that guy in michigan have a website?
 
A 38R with a stocker would be pointless. The system will only flow as much as the biggest turbo would by itself. It's what's feeding the system. A 38R will spool very well on these engines so there is no point in having it be the big turbo in the system. You'd want to add something a lot bigger. Like the GT47 or something similar. This is what I was talking about the hard part being knowing what to put with what. You need to find a turbo that has the flow capabilities you need then compare the map of it to the map of the smaller turbo that you want to run and find two that will compliment each other rather than fight with each other. I'd suggest picking up a book entitled Turbochargers by Hugh Maclnness. It goes over a lot of theory and has a secton for sizing compounds.
I have that book. Good info, a bit dated.. but good. :thumb:

Yeah it is a little dated but the principals are still the same. It's the best I've found on turbos so far. Especially for our application.
 
Well you are taking a set of twins designed to work well on a 6.4L engine at stock power levels and expecting them to work on a 7.3L engine with completely different air flow requirements at over the power levels they were designed for. Probably not going to work to make good power with. Might work OK to make a little over stock power with a quick spool up but the stock turbo does that OK.
 
im pissed I cant even find the dang new issue around the school or gas stations. WTF. dont mean to hijack but 07stroker thats a beautiful truck ya gotchaself
 
your not to far from me. the diesel performance guy who built my truck does twin setups on 7.3's and says its pretty easy on them. now the 6.0's are alot harder to do. if you want, i can give you his # and heres a pic of his new truck with twins. sorry for the crappy pic. it was with my cell phone.
