Hello John
I have the Luminition Optronic with FK123. It came with the car and was reused as part of the restoration in 2016. The control module is now concealed under the dashboard to maintain “originality”. I have the matching Luminition non-ballasted coil. I have never had a problem with it and would recommend. I wonder why you would use the Rover V8 conversion?
Sorry I’ve no experience with oil coolers but check out the archive on the DLOC Forum.
