Converting old junk to EFI with Microsquirt
HTML-код
- Опубликовано: 7 авг 2024
- How do you add multi-port electronic fuel injection (EFI) to an old engine in a car with limited hood clearance? Megasquirt/microsquirt and fabrication, of course! The Toyota 20R/22R hybrid engine is going to take some work to convert to EFI, but the results should be well worth it on our Lotus Seven/Caterham clone.

Just came across your channel. Anxious to see what other videos you’ve got :-)
Dude you have some skills. Nice job! You make me miss my 20R on my 1976 Celica. Never should have sold that car. Replaced it with a 1989 Supra but still.....
Seems like a very reasonable thing to do with jbweld. Looks good!
You take DIY to the next level…👍👍
At last, someone who surfaces their cylinder heads the same way as I do. I also used JB Weld the same. Kerosene is good as a lubricant for the wet and dry paper. I have a supercharged Fiat 850 Sport Coupe running a Microsquirt. I would suggest a supercharger instead of turbocharging for your style of events. The supercharger will give boost just off idle.
did the JB weld trick for pits at thermostat housing mounting years ago. Bead blasted for prep. Worked great
Good work
Great info learned alot
Glad to hear!
I was going to ask why not DCOE style throttle bodies and intake, but thats $800, great work, I will be following!
I looked at DCOE style TBs (they look super cool), but you are right, they are expensive and they don't have a TPS built-in, so you have to use an external one. Also, ITBs are more difficult to add boost to.
really sick dude ! please go into depth with the wiring !
Thanks for the suggestion, I am working on part 2 and wiring is definitely a big chunk of the content.
Those huge sized hemispherical combustion chambers are not great for naturally aspirated engines but throw on some boost and they will wake right up. OFC they will work naturally aspirated and last forever also just down on power compared to other cylinder head options.
The float level dose not dictate mixure
If the fuel is higher in the float bowl, it is higher in the emulsion tube. If it is higher in the emulsion tube, more fuel will pull through the venturi making the mixture richer. The opposite is also true.
Hola desde colombia,estoy en un proyecto similar ,ayuda con la instalación del cableado y los sensores gracias

Sheeesh- why don't you pressure wash the thing before working on it.
It's cold outside!
