you can but you need an adapter to go to the standard airbox ,i made own up, hasn't affected the performance at all, and cost nothing.

I used the same if not slightly less with the weber on the highway. Around town a bit more than stock but yea sounded quiet good so driving style was harder :P . You should be returning numbers around 9-10K's/L with it driving normally.

my webber is returning about 12L/100km and before the standard was about 10L/100 but my motor is pretty fucked, needs a good rebuild... maybe next month

I'm not sure of fuel milage, as my lil lass is mainly for play, id say, maybe 12lph, but the diff in power is amazing, just don't try to climb serious hills, or go down them.

There is a new webber on EBAY that says they have corrected to steep incline flooding issues, I would like to try one, may go for the 38/38, or may keep it stock till I get a 1.6.

hmm that might be a prob i do alot of steep hills and Declines ...i was thinking of getting it of lowrange .. they have a kit with air box i think i could be wrong ..

but in saying that my current stock carby floods all the time on hills

just gets to a point then stalls ..the guy the owned the car prevosly bodgey the carb and took the manual choke out its also burning to much fuel and i cant change that cos he stuffed that up to .. i just thought a weber carby would be a cheaper and better then getting a new stock one or a rebuild on my current one

There is a new version on the market, they are saying that they have eliminated the flooding at extreme angles, Im not sure of it, but have a read, a little bit more than standard, but sounds like the go.

I am thinking the 38/38, not the 32/36.

Get onto Outerlimits and search for a weber thread i started a few years ago. Webers can be modded to fix the hill flooding issues. But the main things you need to do is mount it backwards with the fuel bowl at the firewall. Set the correct float level and seal up the factory float vents and install a new one that vents into the primary throat. All pretty easy stuff to do. Ill see if i can find the jetting and venturi sizes for you.

Also another carby to look at is the Aisin carby from a 3k or 4k corolla. Dirrect bolt on. No adaptors required and it will give you better performance on and offroad over a stock carby. This is what i currently run. Its no weber on the road but its such a simple swap im suprised its not done more often.

It developed a bad vac leak on the throttle shaft just after spending $300 on getting it rebuilt. Took it back only to find the shop had been shut down by the tax department. Not happy. Finnally got in touch with someone and they couldn't / wouldn't help me but they gave me a corolla carby to get me by. It worked but was just about stuffed. did a wrecker search and couldnt find a decent weber but came across a $k corolla carby that looked like it was recently reco'd. $38 and i it was mine.


Its such a simple carby compared to the stock one or even the webber. Dont need to change anything or re-jet it either. You just bolt it on, adjust idle speed and away you go. Stock carby hat fits. Just make sure you grab the accelerator cable bracket as the sierra one doesn't work.

Yeah it is a good conversion and has been around for a long time, I have sent this to a few people on here before.

Fitting Corolla Carbies from K series engines onto Suzuki Sierra

The Toyota Corolla/Aisan carbie is a two barrel carbie measuring 28/28, the standard Sierra/Hitachi carbie is a 26/30 so they are the same total volume size. The slightly larger primary on the Toyota carbie seems to improve the low end performance and once both are open at hiway speed the air intake volume is the same. It is a very simple install because they have the same bolt pattern. You need to port the standard Suzuki thermal gasket to match the larger 28mm venture, use the Toyota gasket for a pattern, also there is a vacuum channel that needs to be cut in the thermal gasket, you will see this if you compare the Toyota and Suzuki thermal gaskets.
You can actually mount the Toyota carbie with the float bowl facing the rear which will make it excellent on extreme hills where it will still idle perfectly. The 3K jetting is nearly perfect but one size larger in the primary jet may increase overall performance. Having a hand choke is also nice. It acts as a hand throttle up to 2400 RPM. The highway performance is unchanged and fuel consumption is usually slightly better. Also you can still use the stock air cleaner after removing the aligning tab and doing a bit of clearance modification for the manual choke. You will only use one vacuum line to the distributor and a vent hose to the charcoal canister.
