Hey
I was just wondering....what's the diff between stock cavalier vs RS vs Z24 (all 2 door models?) I have a '94 RS, but I'm not sure what this means.
Thanks!

Stock - Stock (2.2 I-4, optional 3-speed)
RS - Body Panels, different hubcaps, sway bars, optional 3.1
Z24 - Z24 Body Package, rims, bigger sway bars, strut tower brace, 3.1 standard.

It just goes VL -> RS -> Z24
It increases in performance, mainly in handling, along the way. Body packages get better up the line, as well.

Thanks for clarifying!

Base- no tach, 2.2 OHV (overhead valve engine)
RS- tach, 2.2 OHV
Z24- tach, 2.4 Twin cam

dont forget those.

I didn't. He has a 94, and the twin cam started in 96, the 2.3 Quad 4 in 95, and the 3.1 V6 was in the 94, at least as far as Z24's go.

Ok I'v heard that only the Z24 has the 2.4 engine 150 horse power. Well my wife owns a convertible LS I check what type of engine it has it has a 2.4 twin cam ?? I went to Autotrader and campared cars I then searched for the convertible LS specs Under Engine spec it read 2.2. So why does it have a 2.4 (Swap? or Stock?)

It can come stock, but you have to request it from the dealer, usually. My neighbor's daughter has a RS model 97 with a Twin Cam. It also sports the reworked Phase 2 Z24 rims insead of stock hubcaps or Z24 16" rims. Nifty, eh?
