 thats got a s13 exhaust cam rotated to work on the intake, its off by 3 pins on the chain, the dot on the gear should be closer to the top. 
and there you can see the cam position.... and a few of my goodies :D

Forgive me if I'm wrong, but the key is that the cam lobes are pointing directly away from each other when cylinder #1 is at TDC. There should really be a sticky with photos, since this keeps coming up. I'd hate to see someone end up with ****ed up valves. BTW, what kind of header is that? It sure is purty.

Yes all 240s are the same. Jim Wolf site is a great tool in doing the whole process. Its the only place that I have seen that gives you the picture of the cam orientation at TDC. The biggest thing still is that you have to line up the colored chain links to the corresponding marks on the cam sprockets, idler gear, and crankshaft.

No. Your car would run like shat. Where did you buy your chains from? They all have marks (different colored links) but they can be hard to see sometimes. If it revs fine and idles fine start checking your ignition components, and your fuel delivery.

LiU: I have a s13 exhaust cam as intake and s14 exhast cam as exhaust.. so the colors are a little messed up, and you can tell by the cam condition they are difrent. instead of repining the exhast cam for the intake we rotated the cam gear to compisate
BadMojo: its a SR SSchrome manifold with a KA, and T3 flange on it. Aceinhole was the one who figured out it could be done, and both him and I did this in the same weekend, I like his setup a little better, but mine fits the downpipe alot better. SSchrome just released there KA mani that is the same thing. so its not alot cheaper for thoes peaple wanting a bottem mount turbo on there KA
Oh ya.. FYI thats a s13 head and all the rest is s14

my fuel is ok and i have spark on all 4 cylnders
it was running decent but according to the timing light it was like retarted 40 deg... when i tried to set to stock it wouldnt even start.
Other than the running chitty how can i tell if theyre off for sure?
i resued my chain b/c it was ok and i had to remove cams only b/c i replaced the head...

If its retarded 40 deg. I am surprised that you are running at all. Try setting your timing while the car is running. Its easier this way. To see if your cams are off you can rotate your engine to #1 cylinder TDC, take off your valve cover and see where the lobes of the intake and exhaust cam are pointing on the #1 cylinder. Both of them should be pointing away from the center of the engine. I will try to dig up some pictures from when I pieced my engine together. I think that I have some good photos of the stripped engine that has its chains and cams in at #1 cylinder TDC.

Um, your cams should turn once for every two crankshaft turns. So if you turn the crankshaft exactly twice you will be where you started out. If both of your #1 cylinder cams are facing in you are on TDC of cylinder #4, and cams on cylinder #4 should be both facing out. Hope that this helps.

You are right except the cams are reversed on the s14's so be careful, don't ask how I know.

hey, i wouldnt be too worried about the paint on the cams. the cams really only go in one way with the way they are oriented and how the pins align with chain, etc.
i have always had a copy of JWT's instructions beside me for every cam install ive done.
 KA24DE turbo built all the way

Nissan was nice enough to label your cams, if you look very closely. Check each one, they will have I and E engraved in them. That is how you will know.

hmm, i just swapped my old '93 cams into my new '96 motor, and i've run across a few problems. that image is my '96 cams before i attacked them. i dont have an after pic, but i can tell you that the '93 cams don't look exactly like that...the cams at TDC on cyl #1 with the old '93 cams installed don't point exactly outwards like the other ones did, but point slightly more at an upward angle from the center. this is the only way to angle them so that the valves are all closed. i think that with this setup the intake cam is slightly advanced, and the exhaust cam is slightly retarted by a tooth on the cam gears or a few degrees. with the #1 cyl. lobes pointing out like they should be at TDC, the #3 cyl intake valves and #2 cyl exhaust valves are depressed slightly. i wish i had a picture of the cams the way they are now. btw both cam sprockets are stock, non adjustable ones. i just need to confirm that the cams are off timing...and what about those valves being pushed down slightly? is that a problem or should i focus on putting #1 cyl cams at TDC? AAAH! HELP!

Can anyone with an S13 with cams they haven't messed with tell me if the cams point directly away from eachother or not, and also could they tell me how many links (inclusive) are between the little circular marks on the cam sprockets?

I think the LCA is just different between the two sets of cams. If compression checks out then you're fine.

IMPORTANTDONT GO BY THE COLOR OF THE PAINT ON THE CAMS i have just confirmed that some s13 ka24de's have orange on the intake and green on the exhaust while some others have it exactly opposite. i know this because i just rebuilt 2 heads side by side. they were both from 91 s13's and they were exact opposites. i even installed them both ways and was stumped as to why the lobes were not pointed the right way. then i just swapped them around and found this out.

Interesting. If I recall, the cams have a little I and E engraved on them, don't they?
