I'm in the market for a s400 turbo, looking for somethin to spool as fast or faster possibly with great pump tuning than a s366. So far looking into s467.7fmw anyone running a s400 as a single spooling fast? If so let me know what you got and how usable it is

 

And also what cam would work best for a smaller s400 without fly cutting pistons

 

an s400 is not going to spool faster than an s366. What is the reason you are looking for an s400 and not a good s300?

 

The s366 is the only s300 I'm looking at honestly and goal of 700 hp daily and still tow. Might even look into a auto swap down the road. From the people I know of running a s366 there trucks are tuned clean and still usable just making mid 500s

 

Also have been looking into running the spool valve on the big frame charger. Just looking for opinions. And the s366 isn't out of the picture

 

Look into the new borg s300 SX-E line of turbos. The changes made should make the s300's much nicer than the old style.

 

S369sx airwerks. That's enough said
