During HPC last week, I think I have spun a con rod bearing or damaged the bearings somehow. Mid way through the last session, the car started to make funny noises which I could not really hear with the helmet on. Drove into the pits, took off the helmet and my fears were confirmed, as I was hoping it was something else. Car is back in my place while I gather some parts for a rebuild. I will only know what really happend when the engine is stripped.
Hoping to rebuild it with slightly different parts and make slightly more power than before. The engine just before giving in made about 170+ whp with about 18kg of torque, which is not bad for the 4G93P without any Mivec or Turbo, and running on pump gas.
Lets see how it goes!!! Watch this space!
