Sup guys i need some pistons for my all motor setup... originally was gonna go wiseco ib spec 85.5 @ 12.1 cr............. they had those in stocks... but i recently gain some advice and now plan on going to a cr of 11.1 pistons... i have some flat top valves which will bump compression to something less than 11.5... anyways i dont' think many people have these in stocks or if you do ... pm me... but yeah looks like i have to have my pistons custom made. Any suggestion on a company that make pistons relatively quick?
thanks for your help!

bump

 

bump before my final!

 

I am biased towards CP. But Weisco and JE are both greaat pistons as well.

Check out IB or Edyyn they both sell nice versions of Weisco's

 

might have to go w/ CP, IB don't have the compressioni want, and i here too much bad stuff about endyn

 

CP and JE are typically about two weeks.This is about the busiest time of year and they might be out to 3 weeks now.You need to decide your compression ratio first.A word of advice on cr.Your better being a little low than too high.You will lose more power retarding the timing to keep it from detonating than you will from being a touch to little cr.

IB hast 12.1 in stock, i know thats high for pump gas, especially since i have a gsr head plus flat top valves, but is it possible to decrease compression by a point if i had the chambers in my head opened up?

 

Opening the chambers up will help a little.You may be able to have the dome machined down a little too.Have everything measured,you may be closer to 11.5:1 than 12.1:1.
