Side draft Weber

[cjdeane10]

I have a 40mm DCOE side draft weber (and a bucketload of jets) from an old escort panelvan which i have recently sold.

(i replaced the sidedraft with a 32/36 downdraft weber, and manifold, before i sold her).

Does Anyone run sidedraft weber (of any size) on a sierra?
Is there manifolds available?

Would a sidedraft be better or worse on 4wding inclines (no flooding)?

It used to run very well on 1600 Xflow motor!

I've been told the sidedraft is way better than the downdraft because the fuel bowl is under the inlet? and so won't flood as readily as the downdraft. something like that anyway... i looked into it a while ago but couldnt find any manifolds. Apperently calmini and Redline made manifolds but i couldnt find any trace of a manifold. Probably have to go custom

you would have to get a manifold or an adaptor made to run it. but it would be my first choice of a carby for the zook

Redline made one, but it was for twin webers.
one side might fit a 1litre manifold.

If you are dynamite with tuning a webber, maybe you could get a result, however, stock sierra carbies are a pretty good compromise for the vehicle. Sierra carbs only start to lean the engine out at very high revs (well beyond redline) up to that point, they fuel fairly well.

Personally, I would only be looking at changing the carb if you had made other significant breathing modifications to the engine. Changine the carb alone won't be worth the effort as there will be a very small change in power and alot of time, fabrication and potential drivability issues befoe getting it right.

Even once you have it as good as it could be, it still won't be as good as EFI for off road use.

Yeah - i have the carby sitting around, tis all. Had alot of practice playing with them - have found them to be great on all the older cars i have done up!

Thinking about it, i might be able to just sell the carby and use the cash to support other mods (extractors, snorkel, etc).

That is if the cash doesnt go walkabout on other things! And the war office lets me spend it on the car!

p.s. i am a member of campingWA.com, but i think a few of the blokes we have gone 4x4ing with are on both.

Sounds like a good move, although if you can arrange a swap for something... no money changes hands.... flies under war office radar

Nice!

the carb will be returned to the shed until i can sell/trade it.

If anyone hears of any sidedraft manifolds for sierra's, or anyone else that is running them, pls let me know!

rod from one stop suzi shop ran twin side draft webbers on his old red zook think he's still got the old manafold, he ran it with a big cam and head work and the thing would literally rev its tits off went hard too, 9000rpm was easily achevable with this setup, think he ran a G10 suzuki engine which is esecentually a de-stroked G13 engine which = BIG revs
