help with SOHC and DOHC

[isa1023]

locally, for the sedan, there is only the SiR model which have a DOHC engine. everything else has a SOHC engine. of course, some of the 2nd hand models being sold in the market had already undergone engine transplant.

for the FD model (2006-present), one model is equipped with the 2.0 DOHC engine.

Sir I think a top-of-the-line model Civic ES (dimension body, eagle eye) also has a DOHC --- the k20 i-vtec..
