The original carb on my '88 4x4 Justy wasn't working all that great (rough running, hard to start when cold), so I decided to change it out for a Weber 32/36 DGEV . The manifold adapter I used is Weber p/n 99004.731 and is meant for a Subaru EA82 engine. For my throttle linkage, I used the bracket from a 101.099 linkage kit, and the pulley from the Hitachi carburetor. I didn't want to have any ice issues, and I wanted the car to stay quiet, so for the air filter, I used a carb-heat equipped airbox from a Toyota Starlet, modified to fit the Weber. For now, I'm using the out of the box jet sizes, and the car's running great. I originally had tried swapping the 140 main jet for a 100, but that caused it to run very poorly. (@1700ft altitude). Here are a few pictures - Before - PC310084 by EasleyRdr, on Flickr After - P1080093 by EasleyRdr, on Flickr P1080094 by EasleyRdr, on Flickr P1080092 by EasleyRdr, on Flickr P1080096 by EasleyRdr, on Flickr P1080098 by EasleyRdr, on Flickr As if nothing ever happened - P1080097 by EasleyRdr, on Flickr Since I bought the Weber used, the total cost of this operation was only around $150 usd which is far less than I would have spent getting the Hitachi rebuilt, or installing EFI, and I think this works just as well.

I feel much better about the appearance under my hood now. Can you add what you did as far as the vacuum lines? Thanks for the write up

I feel much better about the appearance under my hood now. Glad I could do that for ya! As for the vacuum , I just removed all of the lines that pertained to the original carb. All of the lines that come from the manifold are still intact and the charcoal canister is still part of the system. The only ones plugged into the weber are both for the distributor.

thanks, just got mine back up and running but the car sat for 6 years and the carb needs some TLC. Debating this mod but being the car only has 40K on the odo thinking of trying to keep it OEM.

Gas Mileage Update -
My fuel economy has actually improved slightly with the weber. I'm now getting about 27 - 30 mpg, and thats with 140 / 160 main jets. My spark plugs are reading very light tan, and I'm actually surprised it's doing so well with such large jet sizes. When I first did the swap, I tried using sizes 110 / 140 but that was way too lean for mine and made the car completely undriveable.

I like the use of differnt car parts, and you worked it out nicely. Is the acceleration better than stock on this set up? And what jet size are you going to use?

Acceleration on the primary side is definitely improved, but with the secondary open, it seems to have lost a bit.

32/36 dgev ea82 is this right? That kit should get you the correct manifold adapter plate. If I were doing it, I would try to re-jet to match the engine. I think you could get mid 30s for mpgs and great driveability with a properly jetted Weber.

Whats the flow rate for the webber comparied to the stock carb? If it can flow more then the speed of air passing through the venturies (for a similar efficiency of design) will be slower, causing less preasure drop and less fuel flow, hence the need for larger jets (less preasure difference requires bigger bore to get same flow rate). If you are dropping performance on the secondary, richening the mixture on the secondary may be the go.

Acceleration on the primary side is definitely improved, but with the secondary open, it seems to have lost a bit. webers can be touchy on the secondarys for jet sizes, i'd look at trying a 170 or 180 and see what it does. If its good on the primary and giving you about 30 - 35 mpg then I am suspecting the secondarys a bit lean when you step on it, assuming you are getting power loss without clouds of black smoke. While the 140/160 is a "std" combination, you might find thats better suited to a 4 cyl setup where the airflow in the inlet manifold's a bit smoother than a 3 cyl. Performance vs fuel economy is always a trade off. Well done with the conversion tho, looks good.

ok got my weber same type and everything.
so why is there a place under the carb where coolant comes out and what did you do about it??

Hippy: That coolant "turn-pike" is to regulate the carburetor temperature; to heat it when the ambient temperature is low, and cool it when it's hot. A regulator, if you'd like.

Could you possibly take pictures of where you connected the vacuum lines from the distributor?
Thanks

Guys... has anyone ever used this trans-dapt 2107 adapter to do the weber swap? It looks pretty nice, but it also looks tall, so clearance would be an issue with the standard air cleaner... I got the part number from this guy's post.

I got the part number from this guy's post. JesZek is all about the Weber and is a major proponent and poster of guides. You can trust the information he posts. That adapter is standard issue. On other older Subarus we use a low profile air cleaner, but other members on here that have installed Webers used the standard model. Perhaps they didn't use that adapter; it's definitely kind of tall. EMPI sells the low-pro air cleaners for about $10 I think, so it's not a major investment if needed.
