Quick question everyone, what is the difference from a D16Y5 thottle body and a D16Y8 throttle body? And are there other d series throttle bodies out there for a D16Y5, because i need one.

 

Virtually all D,B,F,H throttle bodies are interchangeable, only minor differences would the the idle air bleed, in which case, stick with D and B series throttle bodies, the Y8 I beleive is 57mm, and the B16a throttle body is 60mm both will bolt up to that manifold.

The Y5 throttle body is small, and I believe has emissions inlets if I recall correctly, all I can definitly recall is that the intake system is clogged with emissions crap that you dont need, see if you can find a y8 manifold, or even a D16z6 manifold.
