cachanilla86 Posted July 1, 2009 Share Posted July 1, 2009 I got a nice AFM from a junk yard Maxima with the L24E engine...I want to know if it is compatible with a 1977-1978 L28E engine. Some people say yes, other say they're not compatible, what you guys think of this? Thanks for any advice. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted July 2, 2009 Share Posted July 2, 2009 I've swapped a 1982 280zx air flow meter into a 1984 maxima L24e engine. I think the early L28s before 1979 require a microswitch inside the airflow meter for the fuel pump control. Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted July 3, 2009 Share Posted July 3, 2009 before 77 they needed the internal switch. 77-78 uses the oil pressure switch instead, and I'm not sure what they used in the S130's Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted July 3, 2009 Share Posted July 3, 2009 Not used in S130s. The S130s used both the oil pressure switch and alternator output to energize a relay and later ones had up to 3 fuel pump relays. To check the air flow meter for compatibility, I would check manuals for both the maxima......or 1982 280zx n/a and compare the testing proceedure and resistence expected on the terminals.
