if you get tuerbo pistons, dont need base plate spacer as pistons are shorter (i think thats correct) to lesson the compression just by installing them, if i were to use regular pistons i would need to use spacer to make less compression. at least this is what i have seen on shintz website about getting the turbo pistons it automatically drops the compression to 9:1. i already have an ecu editor, and data logger, meesed with it to load a custom map, but should be plug and play for a tuner who uses ecu editor to control the injectors, i definitely want the engine buit good. im up for any input so i get it right the first time
Gen 1 bikes still require a base spacer with turbo pistons, gen 2 bikes don't unless otherwise noted.
