The guy responded saying this

"all the d16, zc, d16y8, and other variations of the 1.6 have the same exzact exhaust manifold pattern, meaning u can inerchange , this means that if u have a 87DOHC 1.6 and a 95 SOHC 1.6 the exhaust manifolds will bolt up to each other, turbo variations and interchange ability has nothing to do with it, the motors r the same cubic inchs, that dosent mean that the heads flow the same it just means that u have the same volume of air going thru the turbo and almost the exzact results on DOHC and SOHC, I have had this same kit on both sohc and dohc aplications and honastly i could not tell a diferance"
