Hi all,

 

http://www.ebay.co.u...=item3a81a486b3

 

 

just wondering which carb is this manifold used for,  and can it be used on a mini.  I have two of them and would like to know if I keep them for now.

 

I also have this

 

 

 

and think it is a double exhaust manifold,  mini or metro ??

 

many thanks,

 

Graham

the one in the link fits su hs series carbs as stated in the listing

Graham, manifold is a Metro one,....inlet manifold is a Hiff 44 one( 4bolt holes) but can be used with a 1.5' and 1.75' Su carb but could get problems with vacuum leaks as they only have 2 bolt holes themselves, hope this helps

Seen a few comments about the MG Metro manifold being one of the better ones out there.

That'll accept HS4 and HIF38, I'm not 100% about HIF44 though somebody could confirm.

 

You often find with these there is a difference in height between the mounting tabs of this manifold and the aftermarket exhaust manifolds.

You need stepped washers or trim the inlet manifold tabs down to same thickness

I take it the inlet manifols would have to be re drilled to take an su carb with two mounting screws,  or will it fit anyway??

[lrostoke]

Fits anyway the mounting is same as all the stage 1 kit manifolds..you just put the studs where you need them.

Doesn't fit the HS2 they have vertically mounted fittings.

[Vipernoir]

HS4 and HIF carbs have the same bolt spacings, no drilling required.

 

The exhaust manifold is effectively a cast iron LCB, and combined with a set of Maniflow downpipes is very efficient and much, much quieter than a tubular LCB.

  It's only quieter if you can get the ridiculous OE type flange clamps to seal!
