1.25 or 1.10 AR? S476R T4 Saved up enough for a bad *** turbo. Don't quite know what exhaust to put on it yet...
370 spun to 7k, 6 speed, 9 inch with 3.89's. Primarily a street car.
Turbo is a BW unit, race cover billet 76, exhaust is T4 due to space constraints. Should I do a 1.25 87mm or 1.10 92mm? Or 1.25 87mm?
Thoughts?
Thanks!

Do the 92 mm imo. I have the t6 96mm 1.32 at on the same combo except gears and the 80mm. I have 4.10 now but changing to a 3.70 or 3.50 soon. I don't mind my spool on my starts around 28-3k full boost about 4k. I can even build 12lbs on the 2step at 5800.

FWIW I offer a Borg Warner S476R with a T4 flange and the larger 96mm turbine wheel.
This is built by Forced Inductions and we're a dealer for them.
The 96mm wheel can be built with a .90, 1.0, 1.10 or a 1.25 housing. Jose may even be able to do the 1.32 housing on a T4 flange, but that I am unsure of. For this combination the 1.32 housing isn't needed though.
I have sold several of these units for people with limited real estate to put a larger frame turbo and they work excellent.
I personally would do the 96mm turbine wheel with a 1.10 housing. I also think you'll find that you need more rear gear with the turbo combination.
Spool should not be an issue even with the 96mm turbine and 6 speed trans as long as the cam isn't huge. Something like our 227/227 114lsa Stage 1 Turbo cam would do excellent paired with that turbo in your combo.
