I just wanted to make sure this will work. and ask if there the same or is one bigger than the other (ports)
im putting a D16Z6 ( honda del sol) Vtec intake manny on a D15B Vtec .. reason, to polish it, I have a D15B in my car now, and polishing the intake manny takes a while so ill polish the d16z6 intake manny and take my time on it so it comes out good, then swap them.

 

should bolt on up, maybe a new gasket though.

i beleive the z6 flows better than the 15b though.
