Is a s400-75 t6 to small for a 408 or can I run that for now

 

If you already got it why not just run it see what it can do? It's a simple swap. But depending on which 475 you have mine will handl 1000hp so I would say yours should do well. If not get the s480 good for 1300hp

 

It's suppose to handle 1000 hp

 

Never know til you try. What sort of boost do you want to run?

 

What ratio A/R housing is on it? It should be fine for low to moderate boost levels. You can always upgrade in the future.

 

Don't go too low...keep in mind these are commercial diesel turbos, designed for high boost applications.

 

If it has a 1.32 a/r you will be fine to 900hp.

 

It's a 1.10 and as of right now I'm running 14psi on my 6.0 but it didn't like it that much and I think I messed up a piston so that's why it's going to a forged 408 and it will be at 14 psi still for now till I wanna make more power

 

What happened to the 6.0?

 

Don't know yet I gotta rip it out
