Gas to Diesel conversion

[Nic900]

Hi folks,
Does anyone know how complicated it is to swap a gasoline engine for a diesel engine in a series 3?
The diesel seems to have all the filters and manifolds just wondering about the rest?

Cheers
Nic

What diesel?

[Nic900]

Oh, yeah sorry, the Land Rover Diesel, the engine I was looking at was from a 63.

A different front pipe.
Return line for the fuel tank.
Ideally a sending unit from a diesel so you have the low fuel waring light (not required though)
A good filter (like a Racor)
A diesel ignition switch that has the preheat position or else a separate momentary switch to do the preheat.
Throttle linkage. This can be a stock one or you can rig a cable actuated one from your existing linkage. The diesel injection pump is on the right side of the engine.
An overdrive

diesel conversions <3. we need more diesels in the states.

[Nic900]

Thanks for the info. I am seriously considering it. I believe it will give me more flexability in the future as gas prices rise and alternative fuels become more common, coz sure as s@@t aint giving up my Landy

[KevinNY]

Tom covered it well. If you want to run Biodiesel you would probably want to have the injection pump rebuilt and use new fuel lines.

You will go from no power to really no power. The 2.25 diesels are VERY expensive for parts (the ones that are different to petrol motors).

You could put in other petrol or diesel engines that will give more power and better fuel economy.

[Nic900]

OK, I submit to the collectives experience and ask this.
If I were to entertain an alien engine transplant, which of the available motors would;


a- be affordable
b- easily obtainable
c- involves the least amount of fabrication and butchering of the original setup (understanding that the very nature of the job will involve some)

What Series and what is the intended use? A Rover diesel might do you, and would be the easiest of them all.

200 tdi from a d90

[Nic900]

Series 3, lots or road, some off but I intend to do more off once she's up to snuff

You can bolt a 2.25 diesel right in with no mods to the frame, but I agree with Ian and Kevin. The 2.25 diesel reinvents the meaning of slow.
The 200 Tdi goes in with only minor mount mods, and bolts up to the S3 gearbox. In the likely event Ian starts up on the 200Tdi and availability of spares, Ignore him.

[Nic900]

Well that sounds like a distinct possibility. I like the idea of it bolting straight to the gearbox.
So this would be out of a Discovery?
What would you expect to pay for such an item?

[Nic900]

Hmmm I just found this

Makes for interesting reading.

Then you probably won't like the 2.25NA diesel. I know quite a few people who are fine with them (I like mine fine) but most people, especially those who've been driving coilers and other V8's, don't.
I wouldn't go more than the 200tdi. Even my Perkins 4203 is too much torque for the SIII gearbox.

Another TDi conversion write-up for you
Series III 300 Tdi Conversion

You Should note the following statements at the end:

"the 300 Tdi into a Series Land Rover (Series II, IIA, III) requires the following:

1. Coil sprung chassis. We do not install the 300 Tdi 5 speed into a leaf sprung chassis for many reasons. Some (but not all) being:
-Axle strength. The Series axles won't stand up to Tdi torque. The Defender axles in the coil chassis will.
-Steering. The Tdi requires PS. This is much easier on a coil chassis than a leaf chassis, although it can be fitted as a separate system on a leaf sprung Rover.
-Brakes. The coil chassis have 4 wheel disc brakes, while the Series Rovers have 10" drum brakes (88"). We don't feel these vintage drum brakes are up the the power and speed that the Tdi can put out, so we require the 4 wheel discs.
-Clearance above the front diff. The added clearance of the coil chassis is needed to clear the Tdi's engine placement.

2. Power Steering. The location of the turbo on the 300 Tdi makes it impossible to fit a stock Series steering box. PS must be fitted.

3. Body work. A Rover with Series III or "late" Series IIA front bodywork can have a Tdi fitted. The early Series IIA bodywork (pre-1968) can not. The headlights in the grill take up space needed for the radiator and intercooler. See the engine bay images above to see how tight things really are.
However, if you were to fit Defender style front bodywork to your Series Rover (Series II,IIA,III), the conversion would be much easier and could be done at reduced cost. The other required items still apply, but the Defender front body work reduces the custom work by about half.

4. Gearbox. The 5 speed gearbox must be fitted for the Tdi. The torque of the Tdi would break the stock Series gearbox.

The Disco 200 TDI is a harder swap as the turbo sits down low by the frame rail and somewhat close to the tire when turning. The Defender 200 TDI is better for a conversion.

i was thinking about putting the 2.8td diahatsu in my 109 would you recomend it ? what gear box have you mated to yours . do you think it would be ok on standard leaf springs??? what mpg etc

thankyou
