Help with weber swap

[Markus56]

Is there anyone in northwest Washington who can help me do a weber swap?

 

I'd normally go to one eye, but he is working all the time now.

 

Thanks!

What all do you need help with? Im no where near you, so I cant personally lend a hand, but its a pretty strait forward swap. The only problem Ive really heard of is if the Weber has an Electric choke and the car has power steering, the choke body hits the power steering resevoir and has to be converted to manual choke. Other than that, its just a matter of installing the adaptor, re-routing the PCV lines, and capping/removing un neccessary vaccum lines/solenoids/wires. Then tuning it of course.

 

I usually take off the manifold, cut off and dress any bungs or casting marks I dont want/need, and plug any uneeded vacuum ports, the clean it up a little with a flap disk and put it on then, makes it look a lot nicer when you open the hood.

I probably could do it. I just have no idea where to hook things into, or what gets capped off. Is there a good write up somewhere? with lots of pictures?

With a Weber, all you are running is the distributor vacuum advance and the EGR valve. Both run off the front of the carb - EGR is slightly higher and to the left (often blocked with a small brass screw on brand new carbs or one's setup to run without EGR), and the vacuum advance is to the right. You install the fuel barb from the Hitachi into the Weber (threads are the same) and hookup the fuel lines exactly as they were on the Hitachi.

 

Other than that do a search on how to hookup the breather and PCV lines or just look in the FSM.

 

The rest is just fitting. If it's going on an EA82 then you will need to make a slight dent in the power steering reservoir to clear the choke and you will want to use the plastic spacer from the Hitachi to get a bit more height. Make sure your mating surfaces are clean and flat. NO RTV for the gaskets. They should be dry or if you must - use a product like gaskachinch or anything designed for paper gaskets that is gasoline rated. RTV will melt - don't use it around gasoline. In fact there's very few uses for RTV other than to pre-coat the old-school cork gaskets such as the oil pan.

 

Hook the electric choke wire from the Hitachi to the one on the Weber.

 

Then it's just about starting and tuning. There's plenty of guides online for this.
