I have a 48 IDA Weber from Racing Beat, I am thinking to go turbo, (boost in to the carburetor, 5 to 7psi). I would like to know what needs to be done for that particular carburetor, to work with turbo. I was trying to find some info about this but couldn't, maybe I wasn't looking in the right place!

Does anyone know anything about on how to mod IDA Weber to work with turbo?

 

Just a quick search for "boost prep weber" will turn up all the info you need:

Those should get you started. A general Google search for "boost prepping weber IDA" will help as well, because the information is not rotary specific.

EFI, as always, is superior and the best choice.

 

Thanks !

I will check it out!

 

So, for converting an IDA Weber carburetor to work with boost/ turbo need to be done/add :
- carburetor "HAT",
- boost compensating fuel pressure regulator (for carburetors),
- solid float,
- seal the throttle pin (and other areas where the boost/air may leaks to the atmosphere),

So this is my research so far. Am I missing something or this is it ??

 

Yep, that sounds complete to me. It's been a while since I've messed with any carb stuff but off the top of my head, that's what's required.

If this is for your engine with the semi-peripheral ports, I strongly urge you to go with EFI instead. First, that carb is too small. Second, you NEED the fine fuel and timing control that EFI gives you.

 

Yeah, I am thinking about it. Maybe it is better to just go on and get the EFI system. This carburetor boost prep will probably cost around the same price. So yeah! I don't think it is worth doing it.
