Manifold help needed

[martinformorris]

Hi,
I want to put an HS4 carburettor on my minor I need to know which inlet manifold can I use with a minor exhaust manifold that has had the inlet manifold cut off.

Something like this

That's the one - not the cheapest - but not the dearest either. Used to get them for £5 !!

I note in the description that it is supposedly better than "some cheap copy type." Is that really the case? How does it compare to say, this: http://www.ebay.co.uk/itm/Classic-Mini- ... 19cbb45c78

I can get something like that here in the states, but it's almost $100. But by the time you do the currency conversion, shipping, etc., it might be about the same...

Both much of a muchness. Note they are for the larger 1.75" carb - but the HS4 will fit ok. Be sure to NOT get one like this - http://www.ebay.co.uk/itm/MG-Metro-Mini ... 416a1bbc45 The Turbo manifold is specifically designed to generate turbulent flow and is useless on an aspirated engine.

Thanks for the ideas and help one thing I am worried about is the thickness of the inlet manifold and the exhaust manifold.when bolted to the engine. A friend had a lot of trouble as there was a different of about eight of an inch between the too.

You just file down the inlet manifold to match the exhaust.

You just file down the inlet manifold to match the exhaust.

i would say the opposite, you have no idea how much has been taken off the exhaust, given the cost of a replacement inlet compared to a replacement exhaust, i would start with the exhaust.

The inlet flanges are always thicker than the exhaust - in my limited experience. You can of course mess about with stepped washers - but it's easier just to do a couple of minutes filing.
