Well it depends on what you want to put it in.Originally Posted by spooned-out
The B18 makes great power, with less torque. there more parts for this set up because there is more demand for the B18 in smaller cars.
The H22 is a good bit heavier so it tends to create major understeer in cars that should be running a B18, however the H22 makes good power while still producing the good torque needed to propel a slightly heavier car.
