No, turns out I am good, and found my problem. The cams are in correctly, but the valve shim clearance still is not correct. This explains why my vacuum reading was oscillating. So I am hand grinding them, and clearancing them that way.

Rebuilt head, piston rings replaced, hand cleaned injectors...

Postby neogeoss4 » Fri Apr 27, 2007 3:59 am

i got my head rebuilt, piston rings replaced, hand cleaned fuel injectors, we put it all back together me and my boys and we cant manage to stabilize the engine... it cranks but it shakes and wont stay on... well it's been a few days and its always the same response, the timing is adjusted perfectly to jimwolf specs, but when we crank it and try to adjust the distributor timing, the engine is too unstable, we hafto give it a lot of acceleration just in order to keep it running @ 700 RPM... i REALLY need some help ... please

Silly SR20... Turbos are for KA's!

Is this article for S13 cams in a S13? Or is it for S13 cams in a S14?

What's the best combo of S13 cam's to put in a KA-T S14 head?

Let me know. THANKS!

actually all you have to do is set #1 to TDC and point the cams away from each other. thats how i have had mine for over a year and the thing still pulls strong, no bent valves or nothing. besides, if you think about it... to swap one cam for the other side of the motor and have it run good then it makes sense that the opposite will work as well.

I have a 96 ka in my 93 chassis. I have a set of spare s13 cams. I want to use the s13 exhaust cam(248) as an intake cam. All thats needed is to rotate 4 teeth counter clockwise? Correct?

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.

Sorry for the thread revival

THIS IS FALSE! I'm going to put a rest to which cam is Intake and which is Exhaust.

vvvv Look at my cam pictures below vvvvThis is my EXHAUST cam which clearly has a 1 right above the giant "E" making the above statement false that the 1 is for and intake.



Now here is 2 pictures of my INTAKE Cam:



This is the other side of the same cam showing a giant I. (Look closely)

As u can see the about quote is false however, there are instances when sometimes the about quote is true making deciding which cam is intake and exhaust a confusing one. Hence why everyone is confused like no other.

The absolute best way to decide which cam is which, should be decided by the dowel pins on the front side of the camshaft, where the cam sprocket is located.

If the dowel pin lines up with the 1st cam lobe it is the INTAKE cam.If the dowel pin does not line up with the 1st lobe it is the EXHAUST cam.Here is the best diagram to go by. (as previously mentioned):

GUYS PLEASE HELP ME!!!!!

Dropped the sprocket when doing an exhaust cam install on the intake side. I really need pictures or someone to tell me exactly how the dots should line up and how the lobes should look with #1 at TDC. So if someone could rehost those pictures that were on the first page that would be nice. With a 248/248 setup will the lobes be pointing at the valve cover mating surface like stock?

Thanks.

the one with the 5 53F is intake and 2 53F is exhaust. in other words the one with the green mark is intake, and other one is marked with orange which is exhaust

(I see you have both and S13 and S14)
