Solex 32/34 Z2 carburettor and Inlet Manifold

[saintjamesy89]

Hi everybody,

Does anyone have, or know of these parts for sale? They were fitted to the AX GT I believe. It would make a nice upgrade for my 14TGE.

Consequentially, how do these carbs differ form the solex fitted as standard to the TU3 in the BX?

Thanks,
Tom.

Hi James

I've got a 14 too. I'm in the process of converting the top end to that of an AX GT with a twin choke Weber.

With the AX GT Solex I would guess the difference will be that it has twin chokes. The AX inlet manifold is different as it's water cooled (or so I understand). Having looked at my existing single choke Solex, that appears to have water circulation at the bottom (buggar it, I'll have to get the damn Haynes out now - where will these spare pipes go when the Weber is fitted?)

I've taken the car off the road for the winter and I hope to pay a specialist to do the work for me, but I dread to think how much it'll cost (£1000+ ? EDIT: with a refurbished AX GT head )

Good luck.

water cooled (or so I understand).

Water warmed actually Steve - the manifold for your Weber should be warmed at the base of the carb as well - and there should be a thick fibre washer between the heated bit and the carb to prevent the carb getting too hot and vapourising the petrol (that applies to the Solex as well).

Yes water warmed does make more sense, thanks Brian.

Pay a specialist? Shit mate, I wouldn\'t have suggested doing it to you if I knew you were going to pay someone. It\'s not really worth all that!

If I cannot find a solex carb, is there a weber equivalent available for this engine? I'm sure I have read somewhere that they could be fitted from the factory if you were someone important or the dealer liked you or something?

I could register with the AX club, but would rather try here first.

I have a weber 32/34 dmtl in the shed, would that fit??

Fitted to Land Rovers 2286cc and 2495cc so almost certainly you'd need to calculate new sizes for all 3 jets and emulsion tube and possibly fit different sized venturis as well.

It does have a fuel return system and idle cut-off valve so it's suitable in those respects...

I've thought along the same lines myself - hence why I've laid it up for the winter. The thing is I really like the car. The car was kept garaged all it's life so has no corrosion. The engine itself is strong... Oh I don't know. A thousand pounds isn't a lot of money for a very sorted car with low miles and full service history - and as the alternative would be to run it into the ground...

Can i just interject, will you guys be fitting the cam from AX GT also?

The carb and manifold will not do much except increase your fuel consumption without the cam to match

[saintjamesy89]

I thought there was a negligable difference between the two cams? The GT one being slightly more wild but not really worth bothering about, please do correct me if i'm wrong though!

[saintjamesy89]

I've decided now to see what mpg I get from the standard Solex before I go spending on upgrades, as it's quick enough for me atm. Just want to get it running perfectly!

[Stinkwheel]

There maybe is only a small actual difference in duration and lift on the cams but well im going from seat of the pants feeling. My current BX14 TE doesnt feel anything like the two AX GT's i used to own, wont rev as quick or as hard and wont pull as hard or as long.

For my mind those traits would be more effected by cam than simpy better fuelling.

By all means go for it Why not if you can get the bits, id be surprised if you got that much benefit.

I'm not really looking for more power, I'd just like to cure the hot starting/running issues. As a refurbished Solex was about £250, I thought opting for the cheaper AX GT Weber route would make more sense. I did get a bit excited by the option of a Stage 1 newly refurbished AX GT head for £220.

I have been told that the Weber setup would actually suit the BX as our version of the TU engine has flatter piston tops than the AX GT version. The same mechanic (and AX GT enthusiast) also told me that performance would be improved with an AX GT cam... but as I don't have the data in front of me to show me why this should be the case, I don't know!

EDIT: a poke in the eye would probably be as much use to me as the data now I think about it. Seat of the pants is much more understandable

Jsut bear in mind once you have changed the carb it is classed as modified Tom so could cause insurance bother!

[saintjamesy89]

Poo, didnt think about that. I have decided to keep it as it is at the moment and see what mpg I get, if it's not very good I will consider changing carbs.
