Going from 91ar ehaust housing to a .85?

I have the s366 t4 and looking to down grade from a 91 ar to a 85. Is there going to be a noticeable difference in spool time or should I not worry about it?

2.0 lsvtec twinscroll and all the other goodies to run the turbo.

the .85 IIRC is a strange 6 bolt turbine housing, than what you have. the .70a/r is a better fit and can make significant increase in recovery response. justmake sure you have the 80mm exhaust wheel.
