EFI project has started Options

Just a quick update. MFI to EFI bungs are in and will be using the carbs will just be throttle bodies and port injection.

Have at those questions

Why not use these?

They are a bolt on replacement for Weber IDA3C carbs. All of the EFI stuff is inside the throttle bodies.

Pretty cool - but come on $3800? (IMG:style_emoticons/default/huh.gif)

The thing I don’t get with the Jenvey’s Is where the injectors are spraying to? The angle of the injectors seems to be that they spray into a passage like a carb jet instead of directly into the air stream? Maybe I’m just not seeing it correctly but Google doesn’t seem to reveal details of their fuel flow path?

The potential to use a common set of carbs as throttle bodies and to repurpose the MFI / CIS ports on some of the early engines is what makes this proposal that Ben is showing unique vs a set of PMO ITB’s, Jenvey’s, or any number of other high(er) cost EFI solutions were you have to ditch the carbs and buy all new ITB’s (IMG:style_emoticons/default/drooley.gif)

These are designed for a stealth EFI installation. They look like carbs, and unless you find the wires coming out the bottom, nobody would notice. For a factory six, this would be perfect. Hide a microsquirt ECU under the air cleaner, and nobody would notice the EFI.

The cost of EFI throttle bodies is what led me to making my own for the flat fan upgrade on my car.

Reusing MFI stacks is simple. Just fabricate a TPS mount to replace the switch at the crossbar, and make some MFI to EFI injector adapters.

I actually started on this for my old 2.4 motor. It's not hard to do. Use a 911 hall effect distributor and a toothed wheel behind the crank pulley, plus microsquirt.
