I do prefer the bigger A/R. A .84-.96 , Just do not see any cheap ones on Ebay. My experience with a turbo with too small of a A/R was bad, the bigger A/R was/ is much better.

If the exh housing and / or the turbine wheel are too small, the turbo will spool great, but become a cork at higher rpms and rob lots of power. Too big and the opposite happens. Only recomending what works for me on a inline 6.
