Mike what are you saying? Shane, Cher, Mo, and myself all overlaid a stock 2.4 cam gear on top of a stock 2.0 cam gear and remarked the timing marks. Pretty simple and widely done, back when I did the 2.4 swap I don't think there were 2.4 cam gears available other than stock.

The point you are missing is "Why are they different?"

They are different because the 2.4L belt is longer by one (1) more tooth to compensate for the taller (6mm) deck height of the 2.4L block. Not an even number such as 2 (two) teeth. All remarking the gear does is get you close, but the cams are still off by 1/2 tooth which equals 3-4 deg of timing. If the gears were stamped the same and marked the same they would line up the same, but they don't. That's why Mitsu makes a different gear for the 2.4L. Lining up the marks as close as possible still has the cam dowl pin out of position which is what times the cams.

I has to use Fidanza gears to get the adjustablility to correct the timing. When I degreed my cams (HKS 272's) in both were off by 3-4 deg because of the longer belt. I just remarked the cam gears..

Good explanation. But the fact remains that they made power with remarked stockers, and more importantly i'm out of money!

I wonder how off mine are then if the exhaust is an actual 2.4 gear and the intake is a remarked 2.0 gear?

I am getting aftermarket adjustable cams(I dont care what the cost diffference is!). Do I need to remark them and then add 3-4 degrees?

Just degree your cams so you are safe. Dont just make an adjustment based off the one tooth difference.

Degreeing is too much work. How about when you dyno you play around with them and get some hard numbers. Less work and instant results.

That is a great idea until your pistons and valves do a slow dance.
Dyno time isn't cheap, I"d degree the cams.
Floppy, is someone posting on your computer?

Most off the shelf grinds are just fine and close to perfect at 0,0 for a dsm.

That's the case now, but if someone's buying used cams from a few years back, the Crowers and some others were way off from the card. And that goes out the window for the 2.4's, or any motor that's been decked.

Well of course. That is why we degree cams on all the longblocks we put together, and tune all of our personal cars on the rollers with cam gears.
(yes my cam gears are adjusted, they aren't there for looks).

I was too lazy to degree my cams and just picked up some stocker 2.4 gears for the meantime. $50 in cam gears is just one less night out on the town, which ain't a bad thing anymore.
