quad4

what year motor will fit in my 96z24? it is an auto trans,

Are you trying to put a quad4 into your car?

95 Z24's came with the quad4's.

I thought the 95 to about 99 z24 came with the quad 4, my 97 z has one. So what years is it?

From my knowledge, the 1995 Cavalier was the only cavalier to come equipped with the 2.3L Quad4 engine.

From 1996 up, they changed around the engine and came up with the 2.4L Twin Cam engine.

Both look similar, but there's some differences to it, especially the noticable IDI covers, and they say each name on them.

Now, if they're interchangable, I'm not sure, but who knows. They could be and that could make someone think they have the other motor. I'm not saying you're wrong Jacfourteen, I just overanalyze everything to think of every kind of scenario. Who knows how that got under your hood.

Many people like to also play the swapping around of the IDI cover's game.

Many opt for the High Output stated quad 4 cover.

My bad, I thought they were the same thing.
