Ok so we rebuilt the ka24de and we lined all of the marks up on the timing chain when we did everything and it still dont seem to be running right, maybe off a little bit. So neways we went and bought these s13 exhaust cams but i get them home a look at them and realize that they are slightly different.

heres some pics:







notice that the sprocket bolts are in different areas and the little holes(dont know the name) along the cams are not in the same position. and one has a number 5 while the other has a 3 on it. These both are brown painted and both came out of an s13....so is one 248 and the other 240 or what? we were gona put these in with hopes of getting it right, but now they arent the same either. So do yall have any advice as to what went wrong with the timing?? all the marks lined up when we put them in but it still doesnt run correctly....its slow and the intake makes a weird noise whenever you hit the throttle....any help would be greatly appreciated...thanks.

 

we got the car running now, thanks

 

There not both exhaust cams, In the 3rd pic the cam on the right is an intake cam. The way to tell is the sprocket dowel pin lines up with the first lobs. That means its an intake cam and the other cam is an exhaust cam.

 

wow that could have fixed alot of confusion lol, thanks!
