LS/VTEC
A turbocharged LS/VTEC is a very potent motor. However it is also the hardest to build so that it runs reliably. The LS/VTEC gives the best that the LS and VTEC motors have to offer, the high horsepower from the VTEC and the high torque of the LS. By using the LS block and a B16 head (with a stock bottom end) a compression ratio close to 9.0:1 is attained. If rebuilding the motor, the block can be resleeved with aftermarket sleeves and bored to 84mm resulting in 2.0 liters of displacement. A reliable LS/VTEC motor is very difficult to build, as such it should only be attempted by an engine builder experienced with building LS/VTEC motors. Since building a good LS/VTEC motor is such an art, engine builders charge a premium for their services. Also keep in mind that the bottom end of a LS motor was not designed to rev up to the level where the VTEC motors are meant to shine.

Re:Smoke and boost
All good, I cleaned up the other posts for you.
I'm not telling you to assemble the motor yourself or sleeve it or anything.. I'm just suggesting that you buy a built bottom end then throw your B16 head on it. You don't have to sleeve it but it helps for high boost levels.
Many people run LS Vtecs, you just have to limit the revs to what the bottom end normally takes, you can't go crazy and try and bring it to B16 revs.
What OBD is your car?
