larger cabie for corona

[sam-131]

hi all
i started ripping of all the epa,egr system and after having a look at the carbie i have decided to replace it with a large one well my question is there larger carbie that bolts on. if not i'll have to make a adapter and slap on something like a stromberg or a ida weber
thanks
sam

you should be able to buy an adapter for a webber. The 32/36 webber is a good carb for a stocko motor. You will be able to get a lot more power with the weber, and they are common (2L cortina is a good donor.) and kits for them are about $50 with all power valves etc.

agreed, assuming you have a 18r powered (or 2s even), 32/36 webers are the way to go. price should only be about $50 or so. if your handy with a drill and a file you could make an adaptor plate from alloy

Would changing to a 32/36 webber end up givving slightly better fuel economy? compered to a standard 2sc carbie
What else is involved with changinf the carbie, is it just make an adaptor plate mount in then and plug in fuel lines etc
Also would you need to remove all the polution gear?

cheers

the webers tend to give better atomisation than the Aisans, but you may need to alter jetting for best economy.. luckily that is easy to do...

what emissions things are you thinking of in particular?

[sam-131]

yeh it's a 2sc i not sure if you can get a adaptor plate i was going to get some alloy and die grind it to match

i gave it a drive with out the epa/egr poo and it seemed to rev harder and be more responsive not to add the amount of space reclamed

i'll have to get a 32/36 and slap it on and see what it does

These Weber carbs work great on just about anything from 1300 to 2600cc. The only caveat is work out which kind of choke you want first (for cold starts and cold mornings).

Most of these carbs are 32/36DGAV - auto choke which is activiated by coolant. The choke looks like a bell on the side of the carb with two hose outlets. You need to reroute the heater hoses through the choke. Or you can get a manual choke conversion kit for this carb.

The rarer 32/36DGV has a manual choke. There is also a 32/36DGEV which had an electric choke just like the old 2S carb had, but these are rare second-hand.

Whatever one you pick, you will need to change jets to achieve optimum performance and economy. Jet the primary barrel a little on the lean side for economy and the secondary barrel a little on the rich side.

Personally I dunno bout the chokes, in townsville you dont need one... cause it dont get cold. As for the economy tuning, ive never driven a toyota for economy in my life. In fact, i dont drive any car for economy, thats what my motorbike is for. My 18R with 32/36 was worse on fuel than the aisin carb, but damn i had more power... more so than my mate's rebuilt 18R with stage 2 cam etc and 180 holley. Only thing non-stock on mine was the lack of pollution crap and webber. If you want economy, go a 180 holley. If you want fun, go for the webber.

The 180 Holley is a direct copy of the 32/36 DFV Weber. All the gaskets and jets etc interchange between the two.

The DFV weber or Holley 180 is essentially a mirror image of the DGV. The primary and secondary barrels are on the oppsite sides, so the throttle linkage or cable pulls/twists the oppsite way. It's really down to which you can get hold of easily/cheaply and which is easiest to set up with a cable or linkage. I've never owned a 2S powered car, so I don't know which one would be easiest to link up.

The larger auxilliary venturis on the DFV or Holley (4.5 vs 3.5) may make economy slightly better. Having tried both on the same Gemini engine I couldn't detect any difference though.

Had a friend went from 180 holley to 32/36 weber on his 4K, power improved dramatically after the change, and economy went up the spout. May have been the jetting difference.

Cheers, Owen

Yeah, for best results you can't just whack the carby on.

You really need to rejet the carb which involves a bit of time on the dyno or some experimentation. Unless you can find someone who has the same engine and carb combo, then you can just copy their jetting.

The webber 32/36 is a great all round little carbi, there is also the Webber of the XF falcon as well, these have a diffirent air filter mount profile however, I have used bot of these carbis on a anthing from a 2T Toyota to a Modified 202 holden, As a road car carbi i reckon they have pretty much most things going for them including the availabiltity of jets/emulsions etc etc/

i dont really care about the choke let a lone fuel consumption as long as it's got more balls and the engine breathing better i'll be happy plus it's only a work car
yeh i was thinking about the 34 adm (falcon carbie) but i noticed all the vac lines

[o_man_ra23]

I worked on fords for about 2 years, and found the xd-f webers to actually be a bit of a pain in the arse. They are way oversized for a stocko 2S (would be great on something heavily modified), and have a tendancy to clog up inside from fuel crystalization(cant remember exactly where, but its a pain to clear it). The 32/36 I bought had been sitting in the weather for more years than anyone knows, and after a teardown, bath in petrol/carbie cleaner and a new set of gaskets, it was great guns on my stocko 18R-C. Didnt change the jets, just left the cortina ones in.

Cheers, Owen

The 32/36DGAV Weber is a great little carbie, and when jetted right, they should have significantly better fuel economy than the stocko carb (Bolt on upgrade for Lada Niva ). There are no excuses for not getting the jets right, since there are so many Weber jets out there. It just takes time and patience. A stock 32/36 will be overjetted on a 2S-C, but it would probably run well enough to get to a carb specialist if you don't want to rejet it yourself. Mainly, it would choke if you planted it, and it would run rich at cruise.

They're about $50 from your friendly wrecker, up to about $80 from your evil wrecker, and kits are about $50 (most recommended). And you'll need to make an adpter plate.
