Hi all,

In the process of removing my M103 for a probable top end rebuild along with seals. I may also do the bottom end but I'll assess while I'm in there.

I have MS3X and am planning to update the ignition and the fuel to full EFI and coil on plug ignition. I'll add a turbo eventually, but I chose to do the EFI and spark conversion first, and let it run stably for a while, then work on the turbo.

Two quick questions:

- Has anyone documented the gains (if any) to switching to EFI and updated ignition in the M103? I'm not really looking for much gains, but hopefully a slightly more efficient power-band.

- On the EFI side, the injectors into the intake are pretty tight under the air filter. Has anyone seen or can they show me a setup that works with either the existing intake or modified version of the existing intake?

Thanks!
