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!!!!

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. 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!

I know it could be pipe dreams but I am a dreamer and need to wrench everyday!!!! Gee, this is a very old post that somehow I never saw. If still interested:- Many times I have contemplated adding EFI to a Bellett, like my Sport. As Dean says, many years ago I fitted a DOHC EFI engine to my 1st GT. Took a bit of fiddling but doable. You won't end up with much more power, if any, but it would make the car much nicer to drive. Possibly increase mpg a bit too. AS indicated you need a return line to the tank. I used the standard fuel line for the high pressure side with no issues. It does of course need to be fed from an EFI (hi pressure) fuel pump which I mounted beside the tank, under the car. Pump needs to be a bit lower than the tank itself to ensure it always has fuel. If they run dry they self destruct as the fuel is used to cool them. These days a better Idea would be to use an in tank pump like found in later efi cars. Find the right one and it might adapt easily into the top of the tank in place of the fuel level sender. Most have a sender included also. AS indicated you could use Weber manifold with a suitable throttle body in place of the Weber. Note though that these things are super expensive. Or maybe mod the existing manifold to add bosses to take injectors and use a standard pair of SU type carbs simply as throttle bodies. You will need a fuel rail too. There are places on the web in Australia that sell all this kind of stuff. eg https://www.efihardware.com/ Don't be put off by the pricing.... there are ways to get this sort of stuff from wrecker yards. There are many aftermarket EFI computers available on the market. Most run at least $1000 or so. You can also get DIY EFI computers like the Megasquirt or Speeduino. The latter can be built under about $150 or so, at home. It's a basic computer but more than adequate for this application. It will also control the spark if you wish. You use wasted spark, where two cylinders are both fed spark at same time but only one is on the power cycle. You will need a toothed wheel on the harmonic balancer to get timing info to the computer. Here's a Speeduino PCB on eBay for example. https://www.aliexpress.com/item/1005003315562770.html?spm=a2g0o.ppclist.product.2.ad74PTmRPTmRIv&pdp_npi=2%40dis%21AUD%21AU%20%2456.89%21AU%20%2436.47%21%21%21%21%21%402101c84a16615024494083776e2081%2112000025173252452%21btf&_t=pvid:b723d1d8-cdaf-401a-bb09-6ea21d937590&afTraceInfo=1005003315562770__pc__pcBridgePPC__xxxxxx__1661502449A great project if you some spare time...........

Hey thanks Glenn for your reply. I know I asked the question 3 years ago but I have been having fun updating my Bellett (Stinky) over this time. I am still looking into the fuel injection and when I am ready I will take heaps of photos and information here. Cheers mate.

I am still looking into the fuel injection and when I am ready I will take heaps of photos and information here. Cheers mate. No problem. It's still on my mind also! There's a car that you can take the whole system off. A Holden (small car) i think...... a search might find it. But the particular car has a separate EFI loom that can be removed from the car easily along with injectors and all the sensors. Including the Delco efi computer which can be re-programmed for almost any other car. Software is available to do that. So almost a Plug and Play system. Still leaves mounting the injectors and a throttle body but even that could be re-used with some alloy welding skills. Uses a single throttle body. If I recall the actual car I will post it here.

Gives you all the wiring, EFI computer and throttle body. Great start. If you want to use another computer, should be easy to adapt also. glenn

delco ecu and efi system off pulsar/astra/camira is an easy system to work with and use, can tune yourself also
if you were gonna do it may not be a bad idea to run motorbike throttles or a similar ITB setup, may be easier than modifying the factory intake to suit injector bungs and fuel rails
in terms of controlling it speeduino would be a good choice, just need a crank trigger which you can run off of the balancer with some engineering, could also update the ignition side of it too...

Thanks Kombat. Appreciate you taking the time to share your knowledge. That all sound doable. I agree about the motorcycle throttle body as well - it would be a great option. Cheers Neil
