Had a quick look but did`nt seem to be able to find anything. I think this has probably been asked before and I also think I know the answer, but will a 2.3 - 2.5 16 valve manifold fit a 2.0ltr engine? The down pipes will probably need adapting, but will it fit the engine? There`s one for sale on fleebay. Many thanks in advance Edited by Threepoint, Sat May 7, 2011 9:43 am.

Hi Threepoint These are the centre to centre distances for the exhaust flanges. ![]() hope this helps out mazza |

It may have modern mechanicals and features, but to drive the G-Class feels definitely old school. The combination of 18-inch alloy wheels and Panhard rod suspension make for a unsettling ride on typical UK roads. This isn't helped by woefully imprecise power steering, that can make the G-Class feel much bigger than it is. |

dont think youl get any gains in power or torque by fitting a 23-16 manifold to an eight valve two litre if thats what your after, could be wrong but i think this has been covered before |

I was lurking around this idea before and I did the maths about runner diameters etc. An 8 valver will loose from a 2.3 manifold. 2.0L head has 37mm exhaust port diameter and the 2.3 manifold has a runner of 44.5mm OD. If you consider a max wall thickness of 1.5mm (but more likely to be 1.2mm) the ID is 43.5 which is too big and it will make exhaust gas to loose speed on a 2.0L. It will also lean out the engine and you run the risk of introducing knock (pinging). What you need is a manifold runner of 1"5/8 or 41.45mm OD andwall thickness of 1.5 or 1.2mm if you can find that thickness. I am working on a manifold for mine and I ended up buying 2 manifolds for a C180 kompresor in order to have all those bends in hand and built an equal length manifold by chopping the bends. Don't be confused though C180 M111 manifold does not fit the M102 as the centre to centre distance is smaller on the M111. The runner diameter though is correct for 1.8 & 2.0L engines. For sure you can chop the C180 Manifold plate to adapt it to a plate for the M102 but it will not be equal length runners and you will have to add some small bends to match the smaler C to C distance. It will work better than the original cast manifold though. |
