First of all, what are your plans with the car? Road race, autox, drag? Each motor has its own positives and negatives. If you want a h22, it has more power out of the box but you gotta compensate for the extra added weight by getting better suspension. An h22 weighs about 385 lbs and b series motor weighs roughly around 300 lbs. The h22 I believe is a better motor because it has more power to begin with and it also makes more power after each mod because it has more displacement. And whats al this talk about 700 hp h22's? Be realistic here and don't believe everything you herar from a import magazine. Also remember to upgrade brakes.

I don't know what difference it makes when turbo'd, maybe better because of the displacement, but stock to stock the LS makes more power than a b20. The b20 puts out 124 while the b18 puts out 140

The reason the b18b makes more hp than the b20b is because of the restrictive exhaust manifold the b20 has. The b20 makes more torque tho. You need to look at the torque curve and you will see that the b20 makes more torque throughout the powerband than the b18b. Don't look at peak numbers.

The h22 will put more weight over your drive wheels which can cause a bit more understeer. A lot of people think by dropping a h22 in a civic will make the car crappy at handling. This is not true and just a bunch of rumors. You can make the car still handle good by using integra spring rates, shocks, and lighten up the front a bit by getting a carbon fiber hood and relocating the battery to the back. The should take about 50 lbs off the front wheels.
