Thread: Which is better - 2.25 petrol or 2.25 diesel?

get someone to take a photo of a diesel engined series

look at your series 2.25 petrol engine bay

make whats in the photo appear in the engine bay after youve bolted the the engine to the bellhousing and engine mounts.

Thats what I did.

Here's a start:






I can get more detail if you want.

now you know where the big bits go.

put them there and then work out how all the little pipey bits hook it altogether (remember wires are just pipes for electrons)

If I can convince MR scanner to work I'll scan the fuel system and electrical schematic for the diesel.

I love all this technical chatter! :-)

Thanks Blknight.
Do you know of any conversion walk-through links at all? Having trouble finding a good resource.

Get hold of a genuine SIIA shop manuel - or better still, a parts manuel...

The hardest part is silver soldering a return line fitting into the tank(s).

nahh just t piece the breather.

or fit a combinded diesel fuel sender/pickup.

I have the OEM manuals once youve got all the big bits into place then it becomes usefull.

The schematical layouts dont do a lot for you till you know where all the big bits go and digging through each individual section to find the individual drawings of the components is a PITA.

of course having them side by side as you strip one part out of the doner to install it in the reciever is by far the easiest way of doing it.

The t-piece would have to be in the cab. Much easier to just solder or silver solder a steel or copper pipe into the top of the tank. Or drill and tap a hole to fit a cut down pickup.

As said earlier, the engines are basically the same, so a swap should be not too difficult to perform. But, also as already mentioned, with a functioning petrol engine I would think about it twice. Doing the swap I mean.
Although I am a Diesel-man and honestly prefer a Diesel over any petrol powerplant I have to admit that the 2.25l Diesel will give you a new perception of speed. Or rather the opposite. It will give you the relevation of slowness. The 2.25l petrol is by no means a rocket, but the Diesel will bring this to another dimension. Sure, you'll get some more low-down grunt, but the petrol isn't that bad in this respect either. In terms of fuel economy there is surprisingly little difference between them, unlike a Tdi in comparison to, let's say, a V8. Of course a lot depends on how you want to use the car. Travelling in Diesel-only country will of course push you towards an engine swap, do you want to preserve the vehicle to go on shows, you may wish to keep it as original as possible, although the Diesel was fitted to many military models overseas. In the end, however you decide, it's horses for courses.
