Tbirdsteve 0 Report post Posted June 10, 2004 Anyone know if I can replace my melted/collapsed 1990 M20 pistons with ones from a 1986 M20? I don't want to buy the short block they're in only to find the tops of the pistons are different. Thanks in advance Steve Quote Share this post Link to post Share on other sites

Guest Andrew Report post Posted June 10, 2004 I'm gonna say yes - as long as the displacement is the same in the motor.. a set of oversize 83mm pistons for a 325 is only 1200 bucks... hah. Quote Share this post Link to post Share on other sites
