engine swap ?

Flying Frank · 30-12-14, 04:26 PM

Anyone care to enlighten me on possible problems and requirements when changing a cars complete engine from a carb one up to a complete injected engine. Assume car body shell/model/year are identical.

Thanks.

If you could be more precise mentioning at least chassis you are working with?

Ok, B2, carb to injection.

Air filter bracket, fuel pump assembly under floor and reroute fuel lines. Nothing impossible.

ok thanks, I thought I read somewhere something about needing a special fuel tank as well or was I mistaken ? Special in as much as the one from the "injected" car?

Nothing interesting in etka online catalogue? Haven't seen carb fuel tank in my life. Difference should be only fwd vs quattro tank.

Ok, many thanks for that.

fuel tanks are different don't ask why just know they are when I had to source a replacement for myself. Probably to do with the size of the hose that runs from the tank to the injection pump is quite fat and the carb model is one size diameter all the way through as the pump is driven of the engine on the carb models

Carb and injection tanks are different. I had to have a large bore outlet brazed in when I did my engine swap
