Default engine swap volvo 240

=) wondering what's the best option for an engine swap in my volvo 240 with a B19A.

Whats the most practical ? :

a B230FT and put a 16 valves head on it.
or a B234 and put a turbo on it

Offcourse the engine will be combined with a M90 gearbox.


Thanks !

He means a 1993 or newer model year B230FT - I think. Although I'd just put an LS in it.

Are you from Europe ?

How much work you want to do , and where you want to do the work/spend the money will decide this for you

The guys are trying to tell you that an 8 valve turbo will be the easiest to adapt to your car.

A newer turbo engine from a 900 series will bolt in to your car without much work ,if any.
Then you will need an engine harness from a 240 with LH 2.4 , and use the turbo boxes from the 940

To use the 234 head on a B230 block , you have to get custom cam belt parts , tensioner etc. These parts are available from the aftermarket , or you can use Penta marine stuff for bolt-on stuff. The Penta AQ 171 used the 16 valve head on the B230 .

Either way , it will cost a bit of money. You can also do a budget job with a belt from an Opel , and a tensioner from a VW Golf mk 1.

Most B230 engines use square tooth wheels for the belt , and the 16v use round-tooth , so youll need new cam/crank gears as well...

The manifolds: No b234 turbo engine was ever built , so you will need the exhaust manifold from the ( 2 litre turbo) b204 engine , or an adapter kit to use the 90+ manifold from a b230.

Off course ,a full-on custom tube header can also be used. The intake manifold from the 234 are not considered ideal by most people ,and will be hard to fit in the 240 because of clearance problems.

Again the b204 part can be used , but both manifolds from a b204 are rare , and will cost quite a bit of money.

The b234 block wont fit in your car , right side motor mount will need to be custom made. If you solve this , there is no room for the distributor in a 240 , as it is mounted at the back of the head.

You can use a block mounted distributor on a b230 block , but not on the b234. The shaft in the block isnt there , and you cant fit one....Of course , there is wasted fire ignition without a dizzy , but again.....

You will have to do some kind of custom engine management if you go the 16 valve/turbo route , Megasquirt or something similar is the only way.

If you plan it thoroughly you should be able to swap in a b230 Turbo in a few days. Most 16 valve turbo builds will take a lot longer , and could cost you a lot more

yeah i'm from Europe (Belgium). So its hard to find custom pieces and turbo engines.... )=
Most of the pieces can be ordered in the states but are overprieced when shipping

I dont want an overpowered 240. I will be glad when i have around 200-250 HP.
Maybe the best thing is to get a 740 with a B230FT and swap this engine in my 240. Then i have also all components and wiring. Put work and offcourse money in the engine and hopefully i will get around that 200-250 HP.

Is there any big difference in the B230FT an B23FT ?


Thanks for your help !

There is, they are way different in the inside and the B23FT is way more expensive to rebuild then the B230FT.

Can the harness from a LH2.4 940 not be used in a 940 to 240 swap?

It can with a bit of work.
A 240 engine harness is much easier.

The 240 LH 2.4 harness , is completely separated from the rest of the car.

In practice you change out the engine harness , and the rest of the car stays the same.

If you have a B19A now , the car is probably too old to be prepared for LH wiring inside. You will have to add 4 or 5 wires in order to make the car run.

Then theres also an issue about needing the electronic sensor in the rear axle for the speedo , which your car wont have if its from before 86. You can read a lot about this in previous threads on TB , and elsewhere.

I dont have any experience with the newer models , but have read that the engine wiring is a lot more integrated with the wiring for the rest of the car.

Do a search , many people have done all this before you.
