But more important, that location is so far up on the housing that it's entering part of the compression cycle. Do different models have these at different locations? Because at first glance mine look like they're just above where the intake ports close off. That means you may not get the amount and atomization of fuel that you'd get injecting it lower, into the intake itself or right at the ports (as the primaries do). What I mean is, even if you manage to get this installed, it may not work very well.
Leaving a chip in the chamber is my biggest concern about drilling the housing. This one, not so much. I'm using a MegaSquirt ECU which has the ability to time the injectors. I would have to set it up to open the injector just after the leading apex seal passed the opening. The injector would have to be finished spraying before the chamber closes. For most of the injection event, the injector would be spraying into a partial vacuum. If there is a lot of back pressure, tuning so the injectors spray longer will fix that.
