Fuel Injector Sizing

[decoupe]

I'm using the intake/throttle body and fuel rail from an '81 528i in an EFI conversion on my 3.5l. Do I need to increase the delivery capacity of the injectors? 282 cam and mild porting on an L block. I think the answer is no - but thought I should check before sending the injectors to be serviced.

Damn cold here.

Looks like they were the same in the e12 528i vs 535i according to Real OEM

The injectors are the same for the US 2.8L and the L-block 3.5L for L-jetronic, but are you using the L-jet ECU? What will it do with a 282 cam? It's not mapped for that.

Doug,
I have a chart for the applications and sizing for Bosch in my stash, let me dig it out.

I'm using a fully programable engine management system that will allow any combination of
components and variables. http://sdsefi.com/

Cool. Looking forward to hearing about the results.
