I know that b20's are notoriously weaker than other b motors because the cylinders are bored out to 84mm and there fore are much thinner. I have seen a friend of mines get blown up, although that was caused by a
miss shift from 3rd to 2nd at 8grand. So my question is blockgaurds, are they worth it, i can see how they would substantially strengthen the cylinder wall but also think that because they are so cheap in price and not widely talked about that mabey they are not worth it at all. Tell me what you guys think, interested in a b20 vtec turbo with stock pistons and rods.
