Your 2.2T cylinders were cast iron, and the 90mm cylinders are aluminum. I have not heard of anyone resleeving them. The only reason someone might do that is to meet race regulations requiring displacement to remain under 2.5 liters. I would think that many problems would result from the introduction of steel liners. Heat disipation will be poorer, and some thought would need to be given to the matter of the relative expansion of piston and cylinder as temperatures fluctuate. Shipping the cylinders to EBS seems like an awfully attractive alternative. But then again, that's what I did!

As for cams, I'm using E cams. I think that Solex would be great as well. If you are concerned with track performance the S cam might be a better choice. I am not rulling out the possibility of using S cams in the future.
