working on my buddys gsr build and i was havin a hard time finding the centerline because the cam dwells at peak lift, i was wondering if i could take a reading of the degree wheel when the cam reaches max lift less than 0.003 inch before and after peak lift. and then find the middle of those two positions and it would be the centerline?

 

and when degreeing a cam im making sure that i rotate the crank in the direction the engine normally runs. because i dont want to over shoot the position the crank is supposed to be in, so i wont rotate the engine backward. i figured it would throw off my numbers because the tensioner only works properly in one direction i think.

 

I don't know how much help I can be but i know Skunk2 has a how-to degree your cams on their site. Also check this thread out; https://honda-tech.com/zerothread?id=1883019 in the last few pages some people posted how-to's and more info. Just shift through the garbage.

bump! does anyone have any input on this?

Yup your correct on that one.

Put (2) 5mm dowls (or screws) in those holes that are in the cam journals. Then you line up the 2 dowels with the marks on the cam gears.

FYI set your cam gears at zero (if your using adjustables). Then adjust after you have installed the belt.

Let me know if this helped. Maybe I didnt understand the question?

 

Maybe it was 6mm dowels... I cant remember.... But you will know when you put them in.

 

bump, thanks for trying to help man im gonna try that today

any other suggestions

 

welding rods wil fit in there ask me how i know.

 

have you posted in the tech forum? I know alot about Integras but this is over my head.

 

yea i think ill post this in the tech fourm, because im not getting to many results, but thanks to the guys that tried

 

Oh goddamn I wished I saved my PM's from mikebelben, he explained this to me a week ago. Anyways, the method you described is how he does it. He measures a certain amount of lift when the valve's open, and the same for when the valve's about to close, and divides that in two.

Post this is in the All Motor forum, they go nuts over this topic

 

the whole process of degreeing the cams is in the link above.
there are several different to degree camshafts. It is explained in the 6 pages of posts in the link above when you have non standard motors other things like deck height come in to the equation.get them close enough to run then tune your advance, retardation, and lobe seperation to suit the power curve that you want. But remember to check your clearences or you will be droping valves quicker than I drop work for a beer.

 

look on http://www.skunk2.com/catalog/...1.htm
if you look you will see how to do it. If you dont get it just ask why or how some
body will answer your questions.

 

thanks guys all this information helped, finally starting to move along here with this build. thanks agian
