i found this b20 sleeve info in a google search. i wouldnt bet my unborn child on all the info, but im sure its accurate for the most part.

220whp is a realistic and attainable goal. a basic turbo kit with good exhaust/downpipe will easily get you 220whp. if you do it right, you can spend less than 2000 bucks - still way less than a CAM'd/headwork/etc NA build.

You have to think about a power goal you want, and build from there. The LS can make power, but it has to be build to make and safely handle some real power. You can only go so far before you need piston and rods, or need to resleeve the block, or the head no longer flows efficiently (as if it ever did). That's why say a B16A or a B18C makes more power lb for lb than a non-vtec. A stock B18C1 is going to handle as much power as a 'built' LS. The LS isn't very balanced, the head doesn't flow as well, etc etc...
And Spec, it is in the tune :reechy:
Also, the B20 is the SAME thing as an B18A/B. Same block, same sleeve casting and design, everything is the same, except the B20 has a slightly larger bore. In fact, everything is the same, except the intake manifold, and pistons.
see that link above about the b20
come on snake i kno you're just pulling my chain on the tune issue. a great tuner understands there are factors that are out of his control. if he/she says otherwise, i would take my car somewhere else. i've seen some people think they can magically make power out of a car and have it blow up on them because they think its ONLY in the tune. yeah its a big chunk of the picture but the rest of the setup has to be healthy as well and in my opinion the only real way of know if its healthy is if it has invidual cylinder monitoring. unless it does, I wouldnt put all the eggs in the tuning basket. i've seen people put blind faith into individual wideband 02 sensors set up to read all 4 cylinders and it makes me cringe.
yeah in an awesome world all the injectors and cylinders will get the exact same amount of fuel and air and have the same compression and all. but often times, these 15-20 year old engines have some variance. and thats when they're healthy. throw in a bad injector, or a cylinder that has good compression readings but a bad leakdown reading...
