Will twin weber 40 idf down draught carbys work on 1.6?

Post by **SiKiD_01** » Thu Dec 30, 2004 9:38 pm

i might be able to get this if it will work on the 1.6L.

is this good? i mean, compared to a weber 32/36? i'm leaning towards the weber 32/36 carby, as it seems to work on a few zooks (1.3 and 1.6).

anyone know much about the twin weber 40's?

thanks for any help.

Not sure if they will "work" or not but I have heard that webbers don't like angles.

All the downdraught ones i've seen used on rotaries didn't like angles.But then again a rotarie is an engine that needs a high volume of fuel on tap, the 1.6 could be OK.

Try a search on pirate maybe?

i think u will find they will over fuel the 1.6 alot!!

eh... in rio the the twin carbs are a fave for the bettles... they are 1600cc... probably not a good comparison.. but hey

I run twin 40 side drafts on a 1200cc a12 motor in my datun 1000, and there is no problem with over fueling or angles, though the head is ported pretty heavily, as the motor came out of a race buggy.

youd probly find it better with a single due to better air speed at lower rpm

.the duels would work better at high rpm but might bog down off the line a bit too much for 4wd work.

Yep - I back what he said.

I've got a couple of books on Webers, and somewhere they mentioned that off-road applications should use a heavier float, and set a higher float level. But I'm not sure if they were talking angles or off-road (Baja style) racing.

Whichever way you go, they seem to stress that it's important to have the float bowl in front of the venturis. Of course, with something like DCOEs that's a bit tricky.

Cheers,

thanks for the info.

i guess i should pass on the twin weber 40's then, and i spose if i got them, i'd have to make up an adaptor/manifold to suit the G16a. (and probably some head work too to get it running good)

and about the weber 32/36, i think i can get one, but so far i haven't heard people say DO get it or DONT get it. there aren't many hills and mountains here, but there are a few creeks and ditches with steep banks.
i wonder if its true that a heavier float and higher float level will solve the angle problem. i haven't had any experience with starving and flooding of carbys on angles.

i have also a quote of about $550 to supply, fit and tune a weber 32/36 on my zook. good or bad? more so bad for me, cos i'm a real tight a$$.

i've also read about a blow through carby turbo kit using the weber 32/36 designed for the Isuzu G series SOHC engines. (G161, G180, and G200)
Carby is rejetted to suit engine, and uses a BOSCH efi fuel pump with a boost referenced fuel pressure regulator.
comes as a kit, so will be bolt on for those engines. Apperently, price is $1300+.

forced induction is possible, but oh so so poor....

*head ache*

i should just save for a calmini anvil and some tora tora axles.

thanks again guys.

Ive done the weber transplant on to my 1.3 and i aint gonna go back.

I used a 32/36 on a linx manifold adaptor. if going on to a 1.6 the factory setting from an escort should be suficient. Extractors help heaps in getting the most out of the engine. i run mine mounted backwards (float at the firewall) with a fuel pressure regulator to limit pressure when offroading and have sealled off the original float vents in the carby and drilled a new float ventand run that into a 2nd fuel filter. The hardest part of the conversion is if you intend to reuse the stock airbox. Its very hard to find a air inlet adaptor to suit the squareish shape of the weber. I made my own. its ugly but it works.
I do sometimes jet stalling on steep down hill angles but have not yet experianced it on side slopes or up hill.

But the best thing about the webber is not the extra power,or the improved response but the wicked "BOOORRRRRPPPP" noise when the second barrel opens :lol:

is ya want any pics or jet size details give me a pm and ill try to help
