has anyone ever biult a mini me with a 92 si head? i put the 92 head on my d15b block and found the belt was too long. then i measured the hieght of both of the heads and found that the 92 si was 1/8 of an inch shorter (stack wise). has anyone done this swap? if so was it an 92 si or just like a vtec y8 from an ex? are all vtec heads the same height, or is the si slightly smaller. if they are all the same hieght then what lenght timing betl do i need? (teeth, inches, brand, serial #,) thanks for the help. or should i sell my sohc vtec equipment and go turbo?
