Been there seen done more than once

If you do not know any thing about why do you want to put them on your car

There onloy two reasons to run carbs

you are limited my race series regs and have either the choice of stock unmodified ecu or carbs

the second reason is they sound good but 200bhp e30 on stock efi with be better to drive an probably faster to low down tractability than a the same car making 200bhp on carbs

You could also have a word with a member on here: dcoeinside. He runs a stroker track car with triple Webers. He also has an excellent Youtube channel you could contact him on.

Hard work.

Find yourself an already carburetted car (like an E21 320/6 or an early 4 cylinder E30) and upgrade the carbie setup on that.

Hardest problem with a carburetted RHD E30 is that the rear carby fowls on the brake booster (that is if you are running triple sidedrafts, which of course you would do on an M20).
