I recently bought a 2000 Honda Civic SI Vtec expecting it to be stock... but what i just notice is that, the block is not a regular B16, but a B18C1... which is the same as the Integra GSR.. I also noticed that the Vtec controller is missing, so the Vtec is not operational... i need some guide on finding the right vtec controller for this special engine and more guides on what i can do to get max performance out of it....
