Convert 3l diesel to 4.2 diesel

[ErickvJ]

Is it sensible to convert a 3l diesel to a 4.2 diesel engine?

[ricster]

ABSOLUTELY!!.... haha ... Mine is a 4.2 diesel turbo, and love the fresh smell of diesel in the morning.

The only problem is finding a TD42 motor, they are a bit scarce. The advantage is that there is NO electronics, just put power to the diesel pump and off you go.

Tell us why you are asking?

When is someone going to start a thread about converting a 4.2 to a 3l?

[Magiel Oberholster]

I just like the sound of the 4.2 diesel like Sedric's Patrol

[jeanne.volschenk]

YES ,

For sure, I should have done it years ago. I did it, the best thing I ever did. If you get a TD42 make sure you get the bell housing as well . All you need is two engine mounting the bell housing a pair of pliers to get rid of all the 3L wires en electrics , a cable tie or two to tie all your sensors in a bundle and off you go.

Serious its not an difficult conversion and its worth it. I think the UD40 engine with the Turbo will be a nice motor to have or look for a slightly bent bakkie with a TDI will also make a nice conversion. My motor came from a 2007 bakkie. no turbo.

Do you need to change the gearbox and transfer case as well from the 3l to the 4.2l. The reason why I want to know is that I am looking for a very reliable engine that does not need to be performance driven to tow a horsebox. I don't want to sit and worry when my wife drives the vehicle with the horsebox in my absence. I grew up with Patrols and I must say I always felt safe, a feeling I have not experienced in any other vehicle.

Only the bellhousing, I believe

[jeanne.volschenk]

The 3L Gearbox stays. Like peter says only the bellhousing for the starter. You would use the 4,2 starter. I tow a WJ PZazz just fine with my . I'll put the wife in the back next time maybe I can comment better?

Hallo Jeanne
Do you tow that Pzazz with the 4.2 non-turbo diesel ? I am interested because I bought my Patrol 4.2 diesel (non-turbo) to tow my boat from time to time. Not a huge boat but I might go somewhat bigger. Mine is actually originally a 1996 4.2 petrol but had the transplant to 4.2 diesel some time before I bought it. I love the vehicle but ,as I have posted on another thread, it is very lazy but I have not towed the boat as yet. I am not a fast tower but can one get to about 90/100 km/hr on the open road ? I have realised that the uphills would take a lot of patience. Regards.

I own a 2007 4.2D (Normally aspirated diesel) . Whilst it will tow a trailer full of cattle around a farm no problems, it will battle in the open road trying to tow a large ski boat or the like.

I have towed a relatively small rubber duck and motor, without any issues, and managed to maintain fair cruising speed that was safe as well, however,this vehicle (or motor should i say), is just not a great tow motor for long distance towing (ie: Motorways etc)

Sometimes i throw on the 3m refuse trailer and load up fairly heavy, and it drags that thing around town no problems, highways etc no worries, but it certainly isn't a ski boat or caravan...thats a different story.

I feel that owners wishing to use this motor in such a way will be very very very frustrated in the end. As it is the 4.2 is lazy, but strong, adding to this a heavy load and trailer and it makes for a long stressful day in the saddle.

Just my opinion.

If anyone wishes to try the 4.2 they are welcome to drive mine and see how they like it. I live in CT.
