Thread: Weber 32DGV on a 2.25 Series Motor

Good idea.
I happen to have a fully reco one including rebushed throttle shaft (DGAV with electric choke)which I could be persuaded to sell for $200.
I bought it for my Vitara, but now realize a Holley 180 would be better because the Weber is designed for the LH side of a motor . The Holley is much the same but the throttle opens from the other side and would be a straight run with the accelerator cable. Its currently jetted for a Cortina 2 litre which would be pretty close.

Reading up, the only problem with them is that on really steep hills the bowl can overflow into the venturis, but there is an easy mod to overcome this on the net.
If interested email me on parmbruster@optusnet.com.au. I am in Sydney

From what have read on the UK forums, the Webber is a step backwards from either the Solex or the Zenith originals. The Webber will give better economy but at the expense of mid-range power.

The Zenith is apparently the best of the original carbys.

For what others say from the USA is the webber gets the early 2.25s to haul like it should so I dunno, could be worth a shot. Can only tell you what we've done with mucking around with carbys.

The brother inlaw had the solex to begin with on his 2.25 for a while, even with the motor overhauled was still very tardy off the line but used to cut along at 100 easily. Fuel usage was appauling even with overdrive.

With experiementation tried a few different carbys, Hitachi (dual throat), another Solex, carby off a early hilux, even a stromberg, fiddling with jet sizes and stuff over 3 month periods.
All which did nothing he wanted them to, shifted the power too far up, woefull fuel consumption, became underpowered, couldn't get the adjustments right.

Finally wacked on a Zenith on and made some improvement over the Solex, could actually make it up hills with having to pull back to third but still has problems pulling past 100. Fuel usage improved however still nothing close to being reasonable. Still has it on there however bought another landy an early sIII diesel conversion and let the son have the sII, which is kinda good since he's on P's. Can't get booked for speeding. :wink: Might get booked for driving too slowly though ! 8O


My project, SIIA, has a homemade adaptor plate (½'' steel plate) and the single throat Stromberg with the adjustable jets. Before I started the rebuild, if it was loaded up on hills you could swear it was a diesel with the overfueling but used to keep pulling without falling back on speed much. Would actually out pull the brother in laws on the same hills. The fuel consumption is average considering the motor had been worked over when I got it.

The Weber they are referring to is a little single choke Weber from a Fiat sold a s a replacement kit .
the DGAV should give alot of power high up but good low down because it it vacuum progressive with a smallish primary choke.

The Weber 32/36 DGAV is marketed by Pierce Manifolds in the USA www.piercemanifolds.com with a custom manifold. From reading various forums, it seems to be quite powerful. Below is a table I downloaded off the www a while ago, showing various flow rates for carbys often used in US Series Landys.

Those "better breathing" figures would account for the greater power.

Carburetor sizes by airflow numbers:
Model.....................Venturi dia...............Flow
Solex..........................28mm............... 115 cfm
Zenith........................27mm...............1 27 cfm
Weber 34ICH.............29mm...............138 cfm
Rochester BV..............31 mm.............167 cfm
Weber 32/36..............27/27mm...........191 cfm
(thanks to Jim Allen for the data)

I think the 32/36 jetted for a Landy & including the manifold was about $800AUD.

I've got a spare inlet manifold, and wouldn't mind getting a 32/36 (from Torana locally I think - correct me if you know better) and trying to make it fit. I wouldn't want to spend too much money without having tried it. The Zenith 36IV I've got works pretty well, up to 80kph quickly a gets to 110kph on the flat. Still, better hill climbing power would be a bonus.

please keep us informed on your progress on this subject

Is bigger with carbys usually better though ??

Probably could do the maths but maximum air consuption of the engine determines the size of the carby.

Pommy cars had webbers, which ones (carbies) I don't know exactly, 4cyl. cortinas used to have them and they were 2L I think.

Not picking anyone to bits but just adding thoughts to consider as with mucking around with fueling.

To me the best thing to get a landy motor to perform well is get that 480 pound flywheel lightened some so it's doesn't have to struggle so much to try and spin that and drive the vehicle. After that's done perhaps look at upping the character of the motor.

Gday all

Thanks for all the replys.

I was going to go down the track of using a Pierce Manifolds conversion kit
($436.48 US CIF Sydney), however they are out of stock of a 32DGV carby. The kit without carby $339.47US.That makes****$97.01 for
a carby**** Would love to shop over there..........
A reco 32DGV is $292.5+ locally. So $292.5Aus + $339.47 US just blows it out of all reality.

I dont really want to fit a Zenith or Solex as motor I have for the 88inch
I am fixing up has a gas flowed head,stainless inserts,9:1 CR,headers
Bert Jones profiled cam plus a full balance. Havent started the motor as yet but want to give it the best chance of breathing as possible.

Pat, did you read my progress on the 2.25 heads mods I posted on this forum a while ago? Basically the same as you have done :
[img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img] 8:1 head with some machining - would have loved to go 9:1 & ported, but because it had been repaired, I didn't want to risk too much money on it. Valves to suit LPG, positive pressure seals.
[img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img] cam regrind : all valves open 5deg sooner and close 5 deg later.
[img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img] extractors & exhaust diameter increase
[img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img] new timing belt
[img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img] electronic ignition

now that the cam & exhaust can inhale & exhale better, I think it could benefit from the 32/36.

There are several 32/36 DGAVs on ebay, locally & USA. I'm watching this one in Sydney that's $15.60 at the moment. Auction finishes in 31 hours. Let me know if you want to bid on it & I won't bid against you, but you'll have to let me know how the conversion goes.
