as stated in the title: possible to install diesel engine in gas CRV?

This question is ONLY about 2nd generation CRV, that is 2002 to 2006 models (maybe only 2005 and 2006 models because those were updated. I'm mainly interested in the 05 and 06 models)

can a gas (petrol) CRV be converted to diesel?

in other words, can we put a diesel engine in a gas CRV?

how does the automatic / manual (stick shift) transmission element affects this? is going from one to other a problem or not or what?

like if you find a diesel engine from a manual transmission CRV, can you put it in a gas CRV with automatic transmission?

go ahead spit fire on your keyboards

Anything is possible with enough money.

Another thing to ponder is what about the exhaust and emissions systems? And the fuel systems, from fuel filler nozzle to tank to fuel pump to fuel pipes to injectors? And glow plugs instead of spark plugs? And where would you get an ECU that would understand how to control the diesel engine? And how would you register and title the vehicle? A few places I've lived require emissions testing every couple of years.

Cheaper to just find and buy a diesel powered vehicle that is legal where you live, rather than try to find and build your own.

what I mean is removing a gas block and put a diesel block. a swap. possible?

so I'm mostly curious whether the engine block shapes are different, are both engine blocks the same, and frames the same. in other words: is it plug and play? or do you have to cut and weld?

like in many other vehicles, putting a different engine in the frame...

how about removing the engine block and transmission together?

are the diesel and gas chassis similar ? or do they have different points of attachments for the engine and/or transmission to the body?

explanations are welcome.

simple yes / no is of no use. if you can't back your answer there is no point. I have done my fair share of wrenching I have some idea of what's possible or not. AND YES with enough money everything is possible. What we're trying to do here is assess the level of difficulty. I have done weirder stuff and it worked. naysayers make your case.

I understand it's not going to be a walk in the park, but I'm trying to get some idea of how difficult it is and what those difficulties are.

final point this is not for saving money or other economic reasons etc. this is more like an engineering exercise we want to assess budget tools etc.

I gave you a longer answer and you asked:

So I answered just "No" since I'd already given you a longer answer.

Longer answer #2:

It will require much more than just changing the engine block, and is not going to be easy, simple, or cheap to change your gasoline powered CR-V to a diesel powered CR-V.

here are some pics of the 2.4 gasoline block. Trying to find images of the diesel one so we can do an actual comparison. if someone has some clean shots of a CRV diesel block, please feel free to contribute. I think that 2.2 i-ctdi engine is same as the one in Honda civic in europe.

The first one lists the price as 3316 Euros, which is about US $3656. And it's in the UK, so shipping costs, too.

The second one is in the Netherlands and says "price on request".

Any results from either HondyMon or Hondady?

As you are flagged as being in the USA, you might run afoul of the gendarmes if you try to run your Franken-V on the highway. Not sure what the gendarmes would say if you got your Franken-V to run, but just kept it on your property.

HondyMon & Hondady are both correct when they say that with enough money anything is possible. Building your own plane to fly from Kennedy in NYC to DeGaulle in Paris is possible. It only took the the aviation industry 24 years to go from the Wright Brothers' 120 foot flight in 1903 to Lindbergh's non-stop in 1927.

If I'm still around in 2044, I'll be 94 but eagerly awaiting your write-ups on the venture you both seem to want to start. Good luck.

The legality and emission issues are to be considered. I am going to discuss the matter with my local garage. At the same time there are a few avenues I going to reach out to. The first is an engineering intern who is currently working for Honda. They might have access to more resources that could give us some help. I also have contacts at a local technical college. They are certified honda instructors who teach the honda automotive program there.

I don't think Honda ever sold a diesel CR-V in the States.

It'll be easier to import a diesel CR-V from Europe and spend the money on legalizing it.

Yes, just ask VW how they certified their diesels for US compliance.

That was a newer era when the norms were outside of the physics of our Universe given the technology of the time. Not just the US, EU too. Very few manufacturers have met these norms. VW was chosen to be the fall guy because they had the deepest pockets to pick.

Next year there will be newer releases of current diesel engines with added urea injection to meet the upcoming limits.
