Engine Rebuild Update: Block resleeved & rebored + purchased an ATI Super Damper

The machine shop has returned my spare block and I must say that I am quite pleased with the work done. It has been resleeved and the rebored to once again accomodate the HKS 88mm forged pistons. The reason behind the resleeving is to strengthen the block and as an added measure to ensure the longevity of the new engine. Below are pictures of the finished item:

Next up is to port and polish the head, which is already underway as we speak:

I've also purchased a ATI Super Damper today. The RB crankshaft, being in a straight 6, is quite long and thus prone to torsional resonances at lower frequencies. Without a mass damper tuned to the cranks natural modes of vibration, one could get some nasty and sometime fatal twisting of the crank. This resonant twisting can also break the oil pump. Hence it is crucial to have when rebuilding an RB26 engine thats pushing out more than stock power. Its certainly not cheap but definitely gives you peace of mind.

Thats all for now. Till next time, stay tuned.
