Converting from carb to fuel injection

[andythepandy]

As the title suggests I am looking to convert my carb b230k to a fuel injection engine. I hate the Solex carb on my car and is is a bag of bull****. I am also looking at putting bike carbs on the old girl but also want to weigh up my options.

How hard would it be to convert the engine to FI? is it just a case of adding on the relative FI parts: manifold, injectors, intake etc. and putting in an ECU or is it a lot more complex than that?

I've sold a Stromberg inlet setup from my old spares car to CaptainAhab as he was fed up with his too, coincidentally have the same setup removed from my car sat in the garage

Alternatively, there is a Weber replacement kit available using the 32/34DMTL, should bolt right on.

Two things that spring to mind.

The B230K engine I think had the combustion chambers in the pistons rather than in the head like nearly every other B230 engine. That might mean the injection setup won't work too well, with engine parameters far different to what it is expecting.

You'll need to provide a supply of high pressure fuel. Either change the tank for an injection one with pump, or add a swirl pot and pump setup between the existing tank and engine.

Converting to EFI wont give you much in ways of performance but it will improve reliability.

A standalone management would probably be easiest as itll require the least wiring but itll need mapping.

Bike carbs would be the easiest but they will require a manifold, linkage and setting up. Speak to Bogg Brothers about bike carbs, they know their stuff.

I'm running Megasquirt on my V8 110 Land Rover and it has been super reliable but it isn't a 5 minute job to fit.
Wiring loom isn't difficult but unless you are really happy with vehicle wiring it is daunting
Fuel system needs a feed and return to the tank and its a high pressure feed so some fuel tank mods will be required to a carb tank
You will need a crank speed sensor so a trigger wheel and sensor bracketry will be required, mounting to the crank damper is sometimes a little challenging if you don't have access to machining facilities.
There is a lot of knowledge on the www.lr4x4.com forum. Although that is very Land Rover centric it applies to any engine

Yes it does have the combustion chamber in the top of the pistons I didn't even think about that. Your probably right. Thanks mylittletony but my friend actually has some bike carbs lying around his garage so they're to hand. So it seems like the best option is to just use the bike carbs. The manifold shouldn't be too hard to make as I've got some metal bits and I can weld well enough.

I'll give bogg brothers a ring and speak to them

Also does anyone know what I need to do with the vacuum hoses. If I make a new manifold for the bike carbs can I just get rid of all the annoying vacuum hoses which are plummed into the original carb and manifold

Yes, I'm sure you can. A few years ago I converted a B230K to a Stromberg carb from an early B21A (with appropriate needle) and a basic points distributor with Lumenition.
I binned all the pipes, and just blanked off any tappings that remained. It ran well. (Very sorry I ever sold it )

Going to k jet is easy I did it to a 240 back in the 90s to a 1976 car went from a b21a to a b21e engine and fitted the fuel lines and pumps the wiring is there for the fuel pumps the car was great wen done much faster and better on fuel on a run

Tried this with a 230K.
Several weeks of grief with a transplanted LH2.4 system, then went back to a DVG and powerstage distributor.
Runs well on the high compression engine.
