Ok i'm in the middle of the swap and I am in need of some assistance. I have an extra vtec plug from my SI Harness. It is the VTEC pressure switch. Is the B16B supposed to have this switch? If so I can swap vtec's w/ my old motor. The B16B has no EVAP crap. Do I need it? I'm kind of lost in this area. Does the B18C5 have any evap stuff? What do i do with it, and what does it do for me? I have an extra sensor on the Intake manifold (I believe it's on the second runner). It looks like an air temp sensor. As far as I know my SI wire harness doesn't have it. Any thoughts on this? P.S. I've never swapped a motor out before. lol Are there any articles or pictures on swaping a B18C5 or B16B into an si? Thanx for the help.
