Okay if you wanted a b18 vtec. and you buy a b16a with engine tranny everything you would get from a purchase that comes with everything except for the resistor box of course. could you just buy a b18 block and use the b16 vtec head. and of course while your at it spend a little more for internals.pistons rings bolts.. etc could you have a tourqer motor.. or a b20.. could this happen to any of these two blocks what would i need to do this. i have the b16a and well several of them.. so let me know..
