I have an "ES" motor that is a JDM version. However, it does not have 1, 2, or 3 specified like all of the US versions.

The transmission that came off this motor fits onto my ET-2 block, so it definitely was for an 84-85 Prelude.

I want to rebuild this motor only if I can properly do a emissions/vacuum delete on my carburetors. Would it be safe to assume this one is the same as an ET2, or A18, etc. (excluding the ES1)?
