Okay I am looking for a photo of the exhaust cam shaft with the motor set TDC on the compression stroke. My motor is a R34 Neo running series 2 sensors and AEM. In order to make this work the male key of the exhaust cam shaft was machined off and the key on CAS was machined off too. I have marked the CAS as to where the half moon key would be but with nothing to compare to it hard to get correct. My CAS can go in 10 ways where yours will only go in one way.

So in short if you have a motor sitting around and you can set it to TDC with the case removed please take a photo of the exhast cam where the key slides into.

And for reference this is a R34 CAS. The cam itself has has a centered male key where the R33 has half moon keys on both the cam and the CAS. So where there is the need to run R33 Series 2 ecu such as AEM series 2 on a neo motor you can remove the keys and use the R33 CAS which allows the AEM trigger disk where that R34 will not.

And cams R33 VS R34
