E30 Zone

can the e21 320 intake mainfold system fit on e30 m20b25?

It will physically fit, but it will be a total mismatch and perform like crap.

thinking to covert my injection to weber idf crab using that mainfold. any suggest or web site for selling weber conversation kit or in tis zone anyone did covert thier e30 from injection to weber?

Basically don't.

Carbs have been discussed on here may times before, it's a lot of pain and expense for something that will only perform as well or worse than the fuel injection.

There are many better ways to gain some performance.

my e30 is killing me. and i enable to trace the fault on it. no earth to the coil but got 12v to the coil. so i'm thinking to covert to triple weber at least i more on mechanical site not on the electric site. over here don't have any e30 especially.
