Hidden FI in DCOE carbs

TonyD just posted this over on Hybridz, check this out, http://www.jenvey.co.uk/products2/twin-throttle-bodies/dcoe-heritage-bodies/heritage-dcoe-twin-body-40-48mm-tdsxx

Classic look with modern FI

Those are really cool!

Could this work on a 240Z and you would use two of them?  Would you just need to supply 12 Volts, 45 PSI fuel and new throttle linkage?

Patton makes efi adapters for SU carbs. Not sure which he makes, 3 screw or 4 screw, maybe both by now.

Interesting devices. I think I need to read more about them...

I think you need an ECU and sensors too, right?

The website only lists 3 screw and flat tops...and I have 4 screw carbs on both of mine.

You can get ECU and TPS as part of the kit.

If you ran the DCOE concealed FI bodies you would three of them and a triple carb intake

How about you mount a pair of fuel injectors inside the stock air cleaner box aimed into the mouth of each carb?
Remove the suction pistons and put the domes back on.

Disconnect the original fuel line back at the tank and install an electric EFI pump back at the tank.

One dead headed innocuous black fuel line running into the fuel filter to feed the injectors.

 

Hey... Nobody said it was a GOOD idea...

With patton you can buy their whole kit(they out source the ecu, programming etc) or if you are familiar with megasquirt you can make up your own system and just buy the adapters.

A friend bought the system for his 510.

Don't forget about your fuel supply system. Now your talking high pressure system that will require upgraded fuel lines that have a more substantial return line.  So you need a bigger pump, a place to put it , lines to supply and return it. Power to the pump if you don't really have an electric pump now - which should really involve a relay.  

Then you can move on to the ECU installation .

not trying to slight this product- I think it's great and considered the OER version myself. I've been in the process of the carb to FI conversion and it is involved - just so you know

In addition to the relay, an inertia switch would be a very good idea to kill fuel pump power in case of an accident.
