Just a good 'ol cheap S475 (non ETT) with the 96mm exh wheel and a standard 1.32 housing

What's it take to stay lit?
 
It will depend on several things, timing, porting, cam, etc, but I would say at least 3500 before it snuffs out
 
i have an s476 and have no problems keeping it lit with a VP! but i have a .9 exhaust housing, but mite throw the 110 back on for next year!

I think you probably have the 83x74 turbine wheel though.
 
I ran one of those as well and didn't like the drive pressures with a .9 housing (small turbine wheel) without a wastegate.
 
we leave the line at about 5700...have never got under the charger, but have a pretty big cam, lots of timing, some head work, etc. It will make around 70 lbs of boost.
P.s. It should be an ETT wheel

Got any video of this???
 
I don't believe with the turbo (S475) you have, that you'll be able to switch exhaust housings.

Correct me if I'm wrong....
 
you're correct, anything is possible...put it on as it sits and see what happens!!

When I talked to E.D. about putting a .9 or 1.0 housing on my old s475...but they said with the cost of machining it to work...it'd be better to start with different turbo.
 
If you are paying someone to do the machining for you, it could become a factor.

I would have tried it this past weekend in the open class, but a simple swap with the existing housing meant my downpipe wouldn't work with the 5" exh outlet on this one.
