i have a ls motor that needs new main bearings. so i figured since i want to build lsvtec, why dont i throw some pistons in there. i got a set of used type r pistons and type r rods to go in there. know i know new parts are always better but will it hurt to go with used pistons and rodsin my ls motor? i just want a little more balls before i build my lsvtec. when i do build ls vtec im definatly gonna use new pistons. but for now, will used pistons and rods hurt anything? thanx for the help!
