I am creating this thread to try and gain an understanding of whats involved when properly "degreeing" HKS camshafts to our beloved 2JZ-GTE engine. I want to attempt to do this on my engine but I need to have 100% confidence in what I am doing because I have a interference engine I do not want to bend any valves like the last time (long story).
Anyways I have spent the entire evening tonight reading, scanning, and gathering as much information as I can before I attempt this with my motor. I always enjoy learning new things and I think all of us with HKS cams set straight up are losing out on some HP and drive ability.
Here is a copy of the HKS cam cards that I got when I ordered my cams from MVP a week or two ago.
HKS INTAKE CAM CARD:
HKS EXHAUST CAM CARD:
Here is what I gathered from reading this thread and looking at the cam cards.
PLEASE CORRECT ME IF I AM WRONG.
Intake valve #1 should be open by 1mm (.039inches)
ATDC (After Top Dead Center)
272: -2deg - this seems like its BTDC?
280: -7deg - this seems like its BTDC?
Exhaust valve #1 should be open by 1mm (.039inches)
BBDC (Before Bottom Dead Center)
Since our motors turn clock wise this is what the degree wheel should look like.
If you have any real world experience or know for a fact that what I am posting is correct and true please post up. I do not want anyone to attempt to degree there cams unless they have 100% confidence in there ability to do so.
