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.
Please refer to a previous blog entry on my purchase of a spare RB26DETT head and block, if you do not already know the story behind the rebuild.
Due to the limited availability of aftermarket RB26 parts locally, my tuner thought it best that I purchase items that we had reserved at several Sunway shops.
His fear was that, since these reservations weren't firmly tied down with deposits, the vendors would have no qualms in selling the parts to walk-in customers. And so today we went out and visited the usual haunts of motorheads in and around Sunway.
So while the block was being re-sleeved at the machine shop, we went to ST Wangan. We were there for the following items:
Jun Oil Collar
ARP Bolts and Studs
Our next stop was Samurai Racing for the Greddy Oil Sump.
It will take sometime to rebore the block and port the head, so stay tuned till then.
