Lance.. Im gonna say a billet 64/71 HP, I had one as a single on my 6.0 with 190s and it was fun. Blow into a 475-480 and you should have one fun truck

Lance whatever route you go I would definitely go t4 with divided up pipes with manifolds. The t4 will help keep bp in check when the lp lights. I'd also go big on the lp exhaust housing and turbine as possible. 1.32 t6 for example.

In many conversations with several people that 475 will put you right around 700, and be a fun street truck. Definatly do t4 with divided up-pipes though to keep it from being a spooling nightmare FWIW.

I can't speak for other setups, But mine is working very well with the 62/70 and s478.. if your going to use your truck like a truck this is the way to go.. i would not be afraid to tow anything anywhere with it..

 

[smokinstroker]

Lance just FYI a 62/65/70 was a bad ass little charger on my compound setup. Boost came
On rediculously fast. Unless your planning on towing alot I'd def go bigger, probably a 63/68 or 64/71.

No need to worry about bp, a 45-50mm gate into the 475-480 with a 1.32 housing you'll be golden.

Are the divided up pipes with a t4 housing really helping that much when spooling these bigger turbos?

 

[smokinstroker]

Probably if you keep the housing tight. A .95 housing was a dog...

 

[6.0 p-stroke]

I've gotta figure out exactly what exhaust housing is on it right now, I hope I can do that without pulling the turbo.

I think I've settled on 64/480. it will be t4 since we've already got the pipes for it.

 

[java]

I bet that'll be a sweet setup. Are steed manifolds gonna find themselves there too?

I think I've settled on 64/480. it will be t4 since we've already got the pipes for it.

From the research I have done, I was going to recommend a 64/480 combo as (to me anyways) it seems the 475 would be better suited for a 62 or 63 but this all just me reading. I haven't actually ran either combo so it is MUCH better to hear from real experts. Either way man I hope it works out good for ya. Best of luck for sure.

What turbine wheel you gonna go with in your secondary? 65, 68, 71, 74????

 

[BlueWaffle]

not sure yet. probably not a 74. I don't plan on spraying it so I'm not sure if I'm going to gate it and if I don't gate it, I'd want a little larger wheel on the HP. there is a chance i might have to run it as a single for a short time which is one reason I'd want a 71 wheel. if I was going to gate it, I'd do a 65/68 wheel. still not a hundo percent sure.

 

[Pizza pig]

i'd still go with the bigger wheel regardless simply because of backpressure reasons. The 65 wheel is going to need a gate, whether the housing is internally gated or an external gate, which you said you dont really want to do. internally gated housings are EXPENSIVE, and im not sure of many internally gated t4 housings, if theyre even available.

I would also look into a 63/68/83 from bullseye, that thing should spool stupid fast with matts pipes, and the 68 wheel is a clipped wheel so it flows really wheel and still spools fast. While paired with a 475 that setup should be good for 700 easy with those 200s

 

[Matt]

Run an external gate.

 

[BlueWaffle]

yeah i saw that 63 yesterday. it's about the same price as the 64 so I figure why not just go a little bigger. I'm still undecided though. It's between that 63 or 64. matt is just waiting on me to make up my mind haha

 

[Pizza pig]

Theyre sweet little units.

 

[Cutting-Edge Diesel]

He is going to run a 46mm external fwiw

 

[Extended Power]

What 63 are you speaking of?
