Engine Swap between production Years. who knows?

[lordfranco]

hello!

I am currently talking to a shop owner about Infiniti j30 engines and he's telling me that he can sell me a 1996 engine will fit on my 1993. Does anybody know if this is true? Also will any engine from 94-97 fit on my 93? Thanks!

your mech is forgetting the difference between emission standards. a 94 for sure will work with a 93 and some 95 before they were converted over to obd2. otherwise you will have to swap a few sensors. the 97s also started doing catalytic converters in the exhaust manifolds and added even more emission bs.
