Although I have no first hand experience in this area, I would assume that the stock E12 L-Jet would handle up to a 3.5L. The Euro M535i uses the same injector as the U.S. 528i. The air flow meters for the 2 cars do have different part #'s though. You could probably do the swap totally stock, then if the car seems to lean out at high load/revs, you could bump up the fuel pressure a little. I bet you will not have to.
: I have a 3.5L high compression engine with the stock e12 injection in my car. All i did was stuff the engine in with no modifications to the stock injection. It works fine as it is!
