I have an R33 series 1/2 (not sure) rb25det head for sale, it has no accessories, just the head with rocker covers, cams etc.
Came off motor a few weeks ago due to the motor blowing, only runs on 4 cylinders so thinking rings. Valves all look fine on the head, turns over by hand with no issues, very clean no oil gunk, was re conditioned 7000kms ago, have receipts.
Going to replace the motor with a NEO six so selling off the bits, would suit rb30det conversion. Can get pictures tomorrow but it looks like any other rb25 head, clean with motul 8100 oil used, changed twice in its lifetime.
