After jsut running a full season on 22 psi of boost on the stock sleeves i am ready to tear the motor down and install some sleeves and I want to go up to at least an 84mm bore. Is there any place offering a group buy on them right now or with in the next month? I remember that Golden Eagle was offering one a month or two ago but I didnt jump on the chance and now im regretting that i didnt. Also how big of a bore does JE stock off the shelf pistons? I am looking to stay around the 9.2 cr that I have now.
