What about the new G35-1050 or even the G42-1200?

BTW, people who don't study this stuff carefully imagine that this is Precision's T3 based v-band in/out turbine housing, which is the housing used on the 6266, 6466, 6766 turbos. The 6870 v-band in/out housings are based on a T4 footprint. This housing is the same size housing used on the 7275 and 7675 turbos. Therefore, I went with the smaller .81 A/R to keep spool, but get the benefit of the higher flow because of the larger overall size of the housing itself.
