If you're planning on building up one of these hybrid engines or are just looking to better educate yourself about them, here is some good info i've collected over the past few months:

It will cost between $2500 and $3000 to swap this engine into a non-b-series equiped honda. You are going to need: The Ls/Vtec engine, a B16 or GSR tranny (best gearing), a motor mount kit or the OEM integra mounts, ECU, B18 axles, and you are probably going to have to wire up VTEC, an O2 sensor and a knock sensor.
With this engine you are getting the best of both worlds. The B16's 160hp and the B18's 130lbs of torque.
