I have a Weber 32/36 DGV 5A on a VERY home made manifold sitting around, not doing much.. Does anyone know where I could pick up a manifold of better quality that would suit this model of Weber. It has to be short as I don't want to mess about with fire wall modifications etc. Cheers guys..

I've heard of someone running one of these, or maybe a 34ADM off an XE Falcon on his/her Mini. Just cant remember where or who was telling me, or if there was a commercial manifold around. Give Jim at Perth Carburettor Specialists a call, he's a good bloke and has the skills to back up calling his business that ;) It may have even been him telling me about it.

Cheers,

i had this one

http://www.minimania.com/InvDetail.cfm? ... 003.808PMV

on my car when i got it. brand name on it was Pierce. fantastic quality and heaps of room on a roundy with no firewall mods.

it also mounts the carb the correct way around so that there's no issues with primary/secondary fuelling. if the manifold mounts the carb parallel with the head then your primary throttle will feed one inlet port all the time and the other inlet port will only get dregs of vapour until the secondary throttle opens up.

i sold mine for about 100 bucks from memory i reckon 300 us is a bit rich, check out the uk suppliers.

That would be the down draft off an alloy head Ford. I would imagine you
would need to make a custom manifold to suit a mini and probably have to run it north-south since
the second barrel progressively opens as the revs build.
<edit..woodwormm has the idea.....he beat me to it

Got a few photo's of the offending beastie. Originally it came off of a 1098 and was working. As you can see from the pictures it does run north/south. Oh course it needs some cleaning but it should scrub up okay. Has a nice chrome cover with air filter too..

I reckon it's cool how in the "Customers who bought this item" section for that page it has a rebuilt HIF44 SU.... as if people bought the weber manifold, then said "bugger this for a joke" and went with an SU

that manifold looks like it would do the job very nicely... pity it looks out of place next to your very nicely detailed engine.

is there any chance, ceramic coating or painting would pretty it up enough? the design of it looks good to me...

It does have a certain rat rod.....punk steam appeal to it.

I'd rather have the carby mounted that way as it should give you a better fuel/air distribution. If mounted parallel to the engine one port will be favoured...

The welds are quite nice, I'll give it a damn good rubbing back and get it smoother and paint it. My biggest concern is that the flange is not as thick as the header pipes. I guess I could space them out with half a washer or maybe cut down another manifold gasket and space them out by doubling up on the intake. Suggestions on a decent fix would be much appreciated.

You can see where they've had to extend the runners and thats where most of that grinding is, the rest of it looks pretty good. If I were you, I'd get a tube or two of quick steel and cover the grinding with that to fill it and bring it out level. Then just sand the quick steel back to a nice finish and you're good to go. You MAY be able to use bog, but being in between the extractors it would probably get a bit too hot and burn or fall off, hence quick steel option.

As for the flanges, how much are they out? I couldn't see it being to hard to make some spacers out of some appropriate thickness steel plate. It's not an overly complex shape. Just get some plate, drill two holes with a hole saw the right size, mark around the outer edges of the flange with a scribe, cut out with a grinder and you're good to go. Alternatively, you could just get your extractors skimmed back to suit maybe??

I dont think it would be hard to make the manifold from scratch either. In fact, having just had a look how I would do it, is how I imagine this person did it. Get two of these http://www2.blackwoods.com.au/infoBANKP ... &P=2024509 then weld up the plenum box with the base plate on top, extend out your runners and weld on flanges. Good to go. But I would stay with the one you've got.

Cheers,
