i know that the question that im going to say is stupid but i've heard many people say ls/vtec motor, what does that mean what i have heard is that is like a motor with different parts of other motor is it true and is it better than a b18c1 motor.

 

search for an answer in the all motor section.

 

ls = b18a or b18b

ls/vtec= ls bottom end with a dohc vtec head

 

its simple....

just like ^^^ said
