Rb 20 & Rb25 Cas

[sherman89]

Just wondering if rb20's and rb25s share the same crank/cam angle sensor??

Also side question

When my car was on the dyno it was happily running at 9psi with the timing sitting as it should! But as soon as we ran more than 9psi, the timing would go wacked and jump around causing it to detonate. We assumed this was cause by a faulty CAS but am not 100%

Has anyone else had a drama like this before? If so what fixed it ?

(series 1 rb25 in r32)

Thank you

The CASs are essentially the same. (I've replaced my RB20DET CAS with a RB25DET CAS without any problems)

How did you determine the timing was jumping around?

[Moodles2]

Were you playing with the timing by adjusting the CAS position on the mounting bracket?

Nah did not touch the cas.
