Hey guys just kicking a few ideas around in the sess pool i call a brain, when i came up probaly the most difficult thing i can get myself into. Anyway i was wondering how hard it would be to put a Weber 48mm downdraft carb in place of the fuel injection.
As far as the deal with the computer and all. Am i opening Pandoras Box on this one?

 

The first gen section has more experience with the conversion you are concidering.

 

only prob with the 1st gen section would be that the 1st gen 13b used a distributor instead of a crank angle sensor.... so when the 1st gen guys convert from FI to carb, they can use their stock ignition, right? We'd have to swap out to an earlier one.

 

You should be able to keep the CAS, ECU, and stock ignition setup. I'm not positive though, I think that's just what I read, so wait for more to answer.

 

someone told me you can use the stock s4 ignition but not the s5

 

Eh, I picked up a 1st gen Dizzy with coils and such for about 45 after shipping.. Not to go to Carbed, mind you. I mean, tuning EFI is so much fun with my MegaSquirt

 

I'm not sure why you would want to convert to carb. There's absolutely no advantage at all.

 

poor gas milage! it makes you faster! all the fast cars get bad MPG! on a side note, doesnt someone sell a kit to carb a 13b?

 

Weber and Holley do.

i put a weber ida 48 on my old rx7, if your efi system is working properly then i dont suggest it.

 

mines not :[

 

I hope this is a joke, because just slapping on a carb will not make the car go faster.

Seriously, if you are going to go through all the trouble to carburete the car, just spend the same money and stay EFI using the Megasquirt.
