Increasing Displacement...

[Blammo]

I am curious if anyone has any stats on stock sleeves versus aftermarket sleeves. What kinda of gains do you see on say a B18B with 84~84.5mm aftermarket sleeves versus the stock 81~81.5mm sleeves? Is it worth the extra $1200 or so?

not to thread jack but what kind of horsepower range requires a bore and sleeving...like what's the highest horsepower a b18b will support on the stock sleeves

Could you get a B20 and re-sleeve it to a 2.2l or would you have to buy an aftermarket block?
