Hello everyone!

I have an 83 240 with d24 engine in it. The engine is very worn and i'm considering replacing it (thats the cheapest option in Serbia). It uses 5 liters of oil every 1000km, makes a bad noise, the smoke is blue and diesel has become very expensive in serbia.

Here's the deal:

The car originally had a petrol engine (unknown) than it was swapped with a 2.3 fuel injected (b23) than that was swapped with a b20 and then with this VW d24.

I would like to install a redblock 4 cylinder petrol engine. I know that i have to change the tranny too. Which ones fit? I know that i should be able to swap a 240 engine in, but can i install a 740 or a 940 redblock into my 240? I'm planning of buying engine and gearbox together and putting it in my car. The 740 and 940 are much better options than a 240 engine since they are in better condition here.

I know that i have to change a bunch of other things for example the radiator, but as long as it is possible - i'm willing to do it.

I dont care about horsepower that much, but i would be happiest to just take the 940 or 740 engine and gearbox out of a donor and put it in my car.

I hope that you can help me.

Regards

Sorry, i posted this in the wrong section first time, it should be here

NOTE: all the swapped out engines are still alive - i'm not killing any volvos. My d24 is going into a donor, which will still be driven

 

It is easier than you seem to think: any Red Block will just swap in there, the transmissions are the same too, no need to change radiator or anything else. Best to get a late 1993 or later 940 motor... Will have to address the computer if it was changed to a Diesel one, no telling what changes were made there. How many miles on this car with so many motors changed?

 

Thank you for the reply,

The car doesn't have a computer and it never did as far as i know (i've had it since the second engine).

Here in Serbia it's too expensive for me to do a rebuilt and repairman are more than terrible and also like to steal and cheat, so when time comes, i find someone who wants to my engine and some money for his engine.

No one knows the exact mileage. I'm hoping to pick one with just a few hundred thousand km so i can finally stop swapping.

I'm planning on buying engine and transmission and everything else as whole and swapping them in. The computer and all the nessecary parts should be there.

I've heard that i have to change the distributor location if i pick the 740/940 engine, what do you think? Is there anything else i need to know before doing this?

So far the engines were from 240s but this will be the first one from 740 or even a 940. Except from changing the distributor location, will it just bolt on?

 

Well yes, you have to change the distributor if the donor car has a rear (head mounted) one--the 240 has no room back there; chances are that the 740/940 will have a back mounted distributor. All the rest bolts right in with no need for modifications, as long as non turbo.

If your car had fuel injection, it had to have a computer... Even my '72 164e has a computer... Hopefully the wiring is not butchered, for your sake.

 

Thanks!

The car currently has no computer, it was then removed with the b23. I'm planing to buy an engine with a computer on it in working order. Are those computers just for diagnostics or do they have an actual role in controling the engine and can it work without them (except for the fuel injected ones)?

Regards

 

The computer is responsible for controlling the fuel injection and ignition systems (actually two computers). When picking up the replacement engine make sure you get the whole wiring harness, ECU, ICU and air mass meter. If you are looking for bolt-in air intake plumbing you will have to get them from another 240 as it is different for the 740/940. The mounting of the power steering pump and alternator is also different on a 240 vs. 940.

 

note those computers on the 1989+ LH2.4 240's are both mounted in the passenger footwell. on the older lH2.2 240's, the ECU (fuel injection control unit) was in the footwell but the ignition control unit was on the right fender just behind the headlight.

on a 740 LH2.2 car, the ICU is over on the left side behind the dashboard, while on a 740/940 LH2.4, its on the right (passenger) side footwell, same as the 240.

re: transmission, using whatever comes with the donor engine is likely your best bet. get the driveshaft too, as the front half of the driveshaft is different lengths for different transmissions (M46 w/ OD, M47 5-speed, AW7x automatics)

 

Thank you

I will post when i finish, the time it takes to do this depends on the time it takes me to find a decent engine.
