My s475 was a T6 96 exhaust wheel And 1.32 AR... Gillett Diesel converted the charger to a .90/83/T4... This was origanlly a out of the box T6. I loved the single. So much fun! I also had twins befor with a stock VVT in the valley. I like the twins for towing. Daily driving and racing though. Single all the way.

If you don't mind me asking what did gd charge you to convert your s475

I run an s475 with .90 a/r and 83mm wheel on stock sticks. It's a bit Laggy, but I don't mind it one bit. Would I benefit from going to an 87mm wheel? -(it's smokinu497's turbo that was brought up previously in this thread.)

No, I have 40s. I wouldn't hesitate to do it on stock injectors with a 72mm.

That was my main thing, I didnt know what combination to go with..475/83 or 87 or 472/83 or 87..

I had the 472/83 before, but I think my next turbo will spool better because of the builder of the turbo..truck will be a dd/toy for now, I have another motor incase I get some free time:)

I'm just not sure it's worth while on my stock engine considering it already runs like a top. Make any more power and I'm going to have a hole in my engine.

The 83 turbine is ĺike 4 mm bigger than the biggest s300 models. They typically have higher dp issue's. The 87 helps reduce that problem and is exceptionally high flowing for size. It is a bad ass bang for the size and cant go wrong using it.
