"Banana" inlet manifold.
Had a query from a friend. Will the "banana" inlet manifolds from an early Jetronic engine fit a later head and is there any benefit from doing this powerwise?
They are ALWAYS rustier than you thought!!!!!!

Re: "Banana" inlet manifold.
Hey Ron, interesting question, hopefully your friend is aware that he's gonna need a LOT more parts than just the "banana" manifolds
And while I don't have any direct experience with an exchange such as this one, I don't see why the L-jet setup wouldn't bolt up to a B34 or B35 head
Recall that the M90 also had L-jet injection
I do have an interesting article on the use of early 320i intake "bananas" on a standard L-jet setup, which is "supposed" to produce more power, somehow
I seem to recall something about volumetric efficiency, or some sort of similar rubbish
It's attached
Glad to see you are getting back in action

Re: "Banana" inlet manifold.
I think the e21 intake runners on M30 intake give more torque and less hp. The M30 already makes good torque, so I do not believe it is a great upgrade unless you are doing other engine work.

Re: "Banana" inlet manifold.
Rich at Fritz's Bits had one fitted to a race car - I'm sure he said it was an easy HP gain.
