Brett240 Posted March 17, 2003 Share #1 Posted March 17, 2003 hi i just had a p90 head installed onto my L28 and noticed that on the side of the head it has P90A. This head has mechanical lifters , i was under the assumption that P90 A heads were all hydraulic. is this true? Link to comment Share on other sites More sharing options...
2ManyZs Posted March 17, 2003 Share #2 Posted March 17, 2003 I was under the assumption that all the P-90A's used on ZX's were hydraulic, but, is it possible the head came from an L-series that wasn't used in a Z? Link to comment Share on other sites More sharing options...
Brett240 Posted March 17, 2003 Author Share #3 Posted March 17, 2003 dunno, is it possible to convert hydraulic lifters to mechanical lifters? Link to comment Share on other sites More sharing options...
ZmeFly Posted March 17, 2003 Share #4 Posted March 17, 2003 it seems that a few of the p90a head were with mechanical lifters. while most were with the hydraulic lifters. the reason for this is unknown to me anyway Link to comment Share on other sites More sharing options...
