I am needing to purchase 96mm cylinders for my 2056 build.
My case is a 1.8, so can/should I bore out my stock 93mm cylinders or should I purchase stock cast iron 2.0 cylinders(94mm) and have them bored out, or should I purchase aftermarket cast iron cylinders, or use birals? If I purchase stock 2.0 cylinders, should they be from the same engine case? I'm not sure who all makes cylinders, but European Motorworks says their cast iron cylinders are thicker than AA Performance cylinders. Is a thicker cylinder wall better? Any shared experience with these options is welcomed. I'm also needing a recommendation on the piston rings...Total Seal, Hastings, another brand? I will be using JE forged pistons. Thanks everyone. |

Depending on cost, I'd bore out the stock ones. But there are lots of options on the market right now for 96mm P&C sets.
Back in the old days when I built my 2056 (15 years ago) boring out stockers and using Keith Black flattop pistons was the way to go. These days you have tons of other options. Zach |

Zach I have several sets of cast iron cylinders collecting dust in the shop, given the options, is this still a viable one for street use? |

Yes! The question becomes "can I bore it out, have it done properly, for less then the cost of new cylinders." A good candidate for boring out will be a 2.0 cylinder that does not have cooling fins broken off. With AA P&C sets being so cheap, it may be a close thing to get your cylinders bored out and a set of KB flattop pistons and (IIRC) Hastings rings for less. My 2056 was still going very strong when I pulled it out in favor of the 2258. It was driven hard. Zach |
