Has anyone looked into fuel injecting a 1500cc Bellett?
Is there a universal plug and play kit that suits the G150? Or mix and match?
I know it could be pipe dreams but I am a dreamer and need to wrench everyday!!!!

Plug and play EFI for a Bellett...... :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: Most Bellett owners can't get their heads around a fully engineered and certified bolt on disc brake conversion for them so they still drive around on drums....
Anyway, your best bet would be changing the inlet manifold to a Weber unit and using a bolt on Weber pattern throttle body, then control that with an aftermarket ECU. Or there are adaptors around that allow a side draft Weber to be bolted to various standard manifolds, so that might be a way to go. One of ours is done like that with a side draft Dellorto on it. Also you could add a CAS and coil packs too so you can do away with the distributor and let the ECU control the spark as well.
Would be a pretty big project tho. Needs a bigger fuel line, a return line, EFI pump, probably a swirl pot as well, the throttle body with injectors, a good ECU, all sorts of stuff.

Fuel injection. Yeah. Sounds like a lot of work. But I suppose it could be fun if you wanted a challenge. I like that they carbie meters fuel in a rate that allows adequate performance at a good economy for driving on our roads with our speed limits.
But you have that high speed road up there, so you might get to use the extra performance.

See, I might be strange, but have always thought the old drums were good enough for the weight of the car. I don't tend to use the brake pedal much because I like to change down through the gears. But it is handy in case of an emergency. Like if someone makes a mistake or something. Don't think I've managed to wear a set of linings out yet.

Yes, I have my seniors card now. :D
Cheers, Matt.

Hey Mr Red, fuel injecting an old G150 would not be that hard.

There are efi systems which are made for dummies which are impossible even for the likes of me to stuff up.

if you can make an adapter plate for your carb to intake manifold you could buy a Holley carby lookalike which is actually a fuel injector and throttle body in one. Or a weber downdraught unit. A few options there.

You will need an efi fuel pump (to give you the injector pressure) located below the lowest point of the fuel tank (Glenn P concept on white GT) or a swirl pot as suggested before .

You will need a return fuel line back to the tank usually, unless you can find a flow and pressure regulator.

The rest is fiddly bits.

It wont beat the faster belletts at the nationals this year but maybe 2020 ;)

It will give you some serious fun in learning and playing with something new. Go for it if you can.

Edit: I had a motec and a 24 pound wheel on my Yamaha Jetski, awesome fun. But looking forward to my seniors card soon! :D
