Hi guys
Im wanting to change my 2 1/4 petrol to a 2 1/4 diesel engine.
Is the 2 1/4 DIESEL engine more or less a straight swop for the 2 1/4 petrol?
Also im assumimg i would have to put 109 leaf springs on the front?
Cheers Gavin

yes it goes straight in . If you are going to change the springs , get the right ones for your model with a diesel engine .

You do have to set up the diesel return line and a load of other things that are not on the petrol system too. If your throttle linkage is a mechanical one, then you need to set up a cable operated throttle with the foot pedal so that you can connect it to the governer.

yes , of course theres also the diesel fuel tank ( or sweat a fitting into the petrol tank (( be real carefull )) ) the bigger battery , the ignition switch to work the glow plugs , the glow plug resistor the fuel filter and plumbling . Basically if you have a work shop and the know how you can do it . But expect to find some snags along the way . This is a conversion I've done but I did have several scrap landy to scavange bits off . Have you considered fitting a 2.5 . All the same snags but a much better engine all together .

Thanks for the replys guys.I thought about a 2.5 engine but cant find one for a decent price.There is a member on here selling a 2 1/4 diesel for a good price not to far away from me.
so would i have to change the spring's is it nesscary to do so?
Cheers Gavin

Its not going to collapse or any thing if you dont change the springs . It might lean a little bit or be a bit lower at the front thats all . The diesel is a lot heavier than the petrol but you would not change the springs if you put your spare on the bonnet or a couple of gerry cans on the front bumper . No doubt some people will cry foul but I would not change the springs until they needed to be done anyway . I remember doing this conversion and I never thought about the springs . I sold that landrover and saw it driving about for a couple of years with no problems ( I know cos he kept bringing it back to adjust the brakes or do the master cylinder or some thing ) . Good luck . Feel free to ask if you want to .........Al

thought there was someone with a 2.5 for £75??

I would stick to the Petrol, they are not that much worse on the fuel, have greater BHP and Torque and to top it off they are far more reliable. C**p for deep water though.
What you spend extra in fuel you save in repair costs!

I'd tend to agree. Have you actually sat down and worked out the difference in running costs and how long it'll take to pay back the cost of conversion?
petrol 90p/l
diesel 95p/l
90 x 4.55 = £4.09 per gallon / 17mpg
95 x 4.55 = £4.32 per gallon / 23mpg
Petrol 24 p/mile
Diesel 18.8 p/mile
5p difference so it'll take 2000 miles to pay back every £100 you've spent on the conversion.
If you put in a TDI doing 28mpg it works out at 15.5 p/mile (£100 every 1200 miles)
£250 2286cc diesel 5000 miles
£500 TDI** 6000 miles
Somebody'll probably come along now and prove that either my logic or maths or wrong :lol: and I may well have just contradicted my first statement anyway :roll:

I totally agree . =D>

the petrol throttle link can be converted to fit the diesel without to much prob
and the petrol exhaust is differnt from the diesel it needs to be longer by about 2 inches also the starter is bigger and the clutch is different and eng mounts are thicker and the fan blade is larger so the rad cowling will be to small on the petrol rad
