comedywizard Posted July 23, 2013 Share Posted July 23, 2013 Hi, I know the manifold is different for the DOHC and the SOHC engine, but is the rest of the system that different? Obviously both aerodecks so presume the route, shape & mountings of the mid and back box is the same?Is it just the DOHC has larger bore? Thanks for info.

NIKH25 Posted July 23, 2013 Share Posted July 23, 2013 Yes, route and mountings will be the same, and as you say larger bore, I think it's .25" bigger. The other thing is I believe the 1.6 has the o2 sensor in the decat, whereas the 1.8 is in the manifold. Quote Link to comment Share on other sites More sharing options...
comedywizard Posted July 23, 2013 Author Share Posted July 23, 2013 Ok great, thought may be the case. Its not an urgent job but makes things easier if I need to change exhaust can just get vti one as they seem more plentiful for some reason! obviously slightly larger bore should flow better as well. Yes as you say for some reason the 1.6 seems to have 2 lambda sensors before & after the cat whereas I recently changed the 1.8 lambda and its just got a single one just before the cat.

simpo Posted July 23, 2013 Share Posted July 23, 2013 Won't matter if u just get the cat back won't need to touch lambers Quote Link to comment Share on other sites More sharing options...
comedywizard Posted August 7, 2013 Author Share Posted August 7, 2013 I heard somewhere that MG ZS saloon backbox is perfect fit for aerodeck, presume saloon slightly longer than hatch.Does the MG mid section fit too or is that specific to M Civics?

So don't even bother trying Quote Link to comment Share on other sites More sharing options...
