Our M20 stroker kit is designed to use 135mm length connecting rods. We offer the option to add our Molnar H-Beam connecting rods (with ARP hardware) to your purchase at a discounted rate. These are offered in two variants, one of them being intended for use on forced induction engines.
Optional turbo piston upgrade includes heavy duty piston castings and heavy duty piston ring set for forced induction engines. This upgrade is well worth the investment if you plan to boost your M20 stroker engine.
All stroker kits now come standard with ACL Race bearings! Please choose your main bearing style. You must select early or late model depending on the year that your engine block was manufactured. Typically early model is 1987 and older and late model is 1988 and up.
