basically, the B20 has weaker sleeves, which may not hold up for too long, although 8000rpm should be okay on the sleeves. it will probably net you about 10whp. either block will need mods to support 8000rpm for long. such as main cap girdle, ARP rod bolts, just to name the basics.

To add something if I may, b18a/b are a dime a dozen compared to the 700-800 price tag for the b20, also when you talk with most sleeving companies they normally charge about 100 bucks more for the sleeving of a b20 block, again i am assuming this is because of the design of the b20 sleeves (please dont flame i said ASSUMING).
