I have a d15b7 and i want to know what the difference in proformance is between a y8 head or a 1.5 vtec head if any? and do i need a new ecu for the swap? Any one have a diagram for the wiring of a vtec selioniod? that would help. If the 1.5 vtec isnt to bad on preformance is 50 dollars for one a good price? Just about to make the swap finally!!

 

oh i forgot i have the plugs for the oil preasure switch and selinoide but where do i put the wires? thats why i need the diagram!!

 

the y8 has a higher compression ratio and i believe it flows a little better
