alright folks.. some of you w/ 2.4's that don't browse j-body.org here's a thread there that should be brought to your attention.
here's the jist of everything needed as written by one j-body individual who was in the know...
----------CAM UPGRADE----------
The intake cam is from a 1995 (only) 2.3L Quad 4 engine.. the eighth digit in the VIN is a letter D. Can be found in 1995 Cavalier Z24's, Sunfire GT's, and Olds Achievas. Brand new, it's
--->GM part #24574239($197.64). If you're looking under hoods, the casting number on the cam is 245/742 (which IS the same number as the 2.4L LD9, but has 0.360" of lift), and the casting number on the cam housing/carrier is 24574057.
The exhaust cam is from a 1990-94 (only) 2.3L Quad 4 engine.. VIN D as well. Can be found in 90-94 Grand Am's, Olds Cutlass, Calais, Acheiva, and Buick Skylark. Brand new, it's
--->GM part #24570698 or #22545390 (a little confusion there)($197.64). The cam casting numbers are 255/455 (which IS the same number as the HO cams, but only has 0.3750" of lift, not 0.410") and the housing/carrier itself is 22542963.
If you are going to do this swap, here is the complete list of gaskets required. I bought them not as kits because I didn't want to be left over with gaskets I didn't need. When I compared costs briefly with Nate, it would appear that I didn't spend more than him and may have even saved some money because the kit he got had the head gasket, and I didn't get a head gasket. YOU DON"T NEED A HEAD GASKET FOR THE CAM SWAP! I also bought a new timing chain cover gasket, but you don't need to. Unless yours is leaking, you can re-use it. If your car is pre 1997, you may want to change it while you are in there anyway. Here are the GM part numbers:
12355988($8.46) - Intake or exhaust cam carrier gaskets (upper and lower)
12363173($10.30) - Intake or exhaust cam carrier gaskets (upper and lower)
24575512($30.00) - Tensioner. Not required, but if you have timing chain noise..change this. Also, be sure you are familiar with how this part works because it has to be pre-loaded once installed to snug up the timing chain.
24575513(3.00) - Tensioner shoe. This will probably break when you remove, so change it anyway.
24575255($12.23) - Guide. Not required unless yours are worn.
24575257($12.23) - Guide. Same as above.
24575256($12.23) _ Guide. Same as above.
992704($NA) - Assembly Lube. Good idea to coat the cam lobes and the carriers where the cam contacts with this stuff.
992869($NA) - Oil supplement. The GM manual calls for this stuff when you do the cams.
12360464($28.29) - I think this # is the timing chain cover gasket. (optional)
245752453($NA) - I think this is the # for the water pump gasket kit. This is only required if you are doing your water pump. I did my water pump and thermostat at the same time as the cams.
