ARI Racing used to offer a service to bore out the 2.8 block to 92mm but found that too many 2.8s had insufficient material to allow for such a large overbore. You would end up with a weak (too thin) cylinder wall or a break through during machining. They used to have an explanation on their site as to why they no longer offered the service, but it was a long time ago and its now gone completely. The biggest you can realistically go is 3.2L with the 3.1 crank or 2.9L with the 2.8 crank with the Fiero block. |

yeah, that's why I said "if you wanna be a rebel"...
I'm sure if you spend money treating the block... Better off starting with a 3X00 block...
