I have a 1989 240 with B230E converted to Weber carburetor by previous owner. He used the original intake manifold and crudely fabricated a flange adapter to mount the carb. I would prefer to restore to original K-Jet but the parts are not available so I am thinking of buying a complete kit and a Weber carb. I’ve seen ads for a kit I think is for a marine application Penta. Anybody done this successfully?

I did a carb convertion on a b230F with aB21A carb and manifold and points
distributor using the original intank pump,simple no issues.

P.S. This was before i had brickboard access,knowledge and plentifull
240 parts from rusted salt belt cars.The Lh fuel injection on these
.cars has been reliable and simple

Hi guys, after all this time, I’ve verified this is a B230F with an LH 2.4 originally. I am slowly accumulating parts to restore this to EFI. I am planning to buy a EZ 116K conversion harness from Dave Barton and an ECU/ ICU appropriate for that. It will take some time for all the parts to be complete. In the meantime, I want to run the engine. There are no pertinent emission laws where I live. I would like to run the Weber 32/36 carburetor (from a Ford Cortina) that is presently mounted on it. I will bypass the high pressure inline pump and use a low pressure regulated electric fuel pump specific to carburetors. Here comes the question: what ignition control unit do I use? Thanks!

Correction, according to VIN YV1244883K1339282, it’s a B230F. I can’t tell if it’s LH 2.2 or 2.4 because apart from the intake manifold, all the other parts are missing.

i HAD an 89 245 & Im pretty sure the K jet was earlier,,NOT onnthe 89...

Yes you are correct. I checked the VIN. It’s a B230F with either LH 2.2 or 2.4 originally but I can’t tell which exactly.

You are correct. The k-jet was earlier. Think the 89’s could have been either LH 2.2 or 2.4. I believe the k-jets ended in the early 80’s sometime? As Dave pointed out it, a b230e could be a Canadian car. Or perhaps some other country.

Notice, we are dealing with a B230E -- not the "F" that we US Volvo people are used to. I don't know off hand how the "E" is configured but I'm pretty sure it makes more power than the F. The carbureted motor has an "A" suffix, as in B21A. On one job I used a mechanical fuel pump (have one now in stock) driven by the lobe on the auxiliary shaft. B230 motors may not have that lobe. On the other 2 I used the tank push-pump with a "T" before the carb with the excess fuel directed back to the tank via the cars own plumbing. Both systems worked very well. -- Dave

Thanks Dave, very helpful!

B230E engines were high compression with Kjet.

B230E cars were sold in the UK and Australia. I would have thought Canada, too, but I see no mention of it.

Hi bulletproof, I initially stated B230E because that’s what the sticker on the timing belt cover stated. However, upon checking the VIN YV1244883K1339282 I interpreted it to be B230F low compression with LH 2.2 or 2.4 originally installed. I couldn’t say which because the parts are gone and what remains is the inlet manifold to which the carburetor was attached with a crude flange adapter.. Thanks for the reply!

Are you in the U.S.? In the U.S. 89’s are either LH 2.4 or LH 2.2 fuel injection systems. My 90 was a LH 2.4. IMHO, I would stick with that and not mess with a marine Penta setup. Other parts on your car were built to work in conjunction with the F.I. system. Not sure about jetronic but if it was an LH system there are lots of LH 2.2 and 2.4 cars out there so parts shouldn’t be a problem. Check the boneyards if you can’t find new. Good luck with it!

Sorry, I checked the VIN. It’s a B230F with LH 2.2 or 2.4. I’m in the Philippines. VIN is YV1244883K1339282

There are/were 240's in Canada that had a single side draft Stromberg carb. I've done that conversion on a couple of cars. A marine manifold that uses a 32/36 type Weber carb (I've never seen one personally) would work but use an automobile carb. Pintos and Vegas used a Holley version of the 32/36. I have carbs. -- Dave

What’s the difference between a marine and car application? How can I tell? I think the ones for sale on Amazon and EBay are marine though.

You previously asked how to find the Stromberg manifold and carb - the ones I used came from Canada on B21A motors. Those were purchased many years ago from Canadian sources so that's where I'd start.
Here's something thing I did when mounting 2 bbl 32/36 type carbs - add a source for coolant to pass through to heat the manifold to avoid "icing" (a marine manifold may not have that built in-I don't know). Renault LeCars (R5 in other markets) used a 30/30 version of the Weber downdraft along with a separate aluminum plate mounted directly under the carb that had a coolant pass-through for that purpose. - Dave

Where can I find Stromberg manifold and carb? Btw, correction, it’s a B230F with either LH 2.2 or LH 2.4 originally.

Interesting, I believe it was the Weber 32/36 that I used many years ago when I converted my 73 BMW 2002 from a single to a two barrel carb setup. It was so long ago I don’t remember for sure...:)
