Wisco pistons rings question

im rebuilding my evo 8 engine which will be running on E85 and will be using links ecm to get it tuned.
Going to use Wisco pistons and Manley rods my aim is to go for 600 to 650 Hp.

For Wiseco rings, .018" top and .024" on the 2nd will be fine. Then of course make sure the oil rails have >.010"
On E85 the gen2 6266 should get over 700whp, I'd run a .0045-.005" ptw clearance to make sure you don't black death a piston. That PTW will work well to over 900ish as well if you end with a larger turbo at some point. And hopefully you got the Wiseco HD's, not the standard pistons. If you really plan to keep it around 600-650, .004"-.0045 will be fine on the ptw.
