Hiya Mr Carmel! :wink: I was told the injectors of a W124 Mercedes 300E have a larger capacity and that they are a straight fit. Should go very well with the 911 dizzy.

The other bonus is that the Mercedes ones tend to be brass. I've got some for my Scirocco.

Can't give you any names but they have a higher flow rate which is required for an uprated engine like a 2.7 stroker as the stock injectors fall short.

Would the mercedes w124 300e injectors be a good upgrade for the normal 2.3 litre running the standard k jet?

Nope. I wish tuning was that easy but it still isn't.

The fuel system is not a bottleneck with a stock 323i engine. It may become one with an uprated setup (increased displacement, more flow in head, faster cam, etc). In an uprated system the modifications already described above will be beneficial.
