what should i do?
 

heres another one,
well as you know im going for the mini me swap for my 91 hatch for now as a 14's car that saves gas. i got the d16y7 block apart and ready for rebuilding. i wanna put the y8 head that i got for the y7 block on my d15 motor for now so i can ride with something at for now since im working on the block. but then i bought a d16z6 motor with the tranny and everything except the disturbitor ad the oxygen sensor. i can use the oxygen sensor from my stock motor but i really need that z6 disturb tho. like what should i do put the y8 head on my d15 motor rebuild the y7 and sell the d16z6 motor or put the d16z6 motor and still rebuild the d16y7 with the y8 head???
