Looking to upgrade the wrist pins in a new set of JE Extreme Duty Invdome pistons . The pins that came with the set are JE's Standard Performance 51 series #927-2950-15-51s (Low Carbon Case Hardened ) . They have a wall thickness of .150" @ 139 grams . According to JE good for about 650hp in a NA application .
Je suggest the 93 series pins (9310 Nickel Carbon Steel Alloy ) for a high HP boost application . I have two choices . One with a wall thickness of .150" @ 129 grams (#927-2950-15-93S). This is the one JE recommends . Or a set with a .170" wall thickness @ 148 grams (#927-2950-17-93S). Would I not be better off with the second set ? or would the pins be to heavy ?
