The Rover-Landers of BC

I was hoping that someone could enlighten me on the various flavours of the diesel engines for the series vehicles, including pros and cons, e.g.:

- diesel 2.25
- diesel 2.5
- 200 tdi
- 300 tdi

Thank you :)

Power and torque are factory numbers for 90/110/130 installations.

These are all indirect injection, similar engines.
2.25D, 67hp and 103 lb-ft
2.5D, 67 hp, 114 lb-ft
2.5TD, 85 hp, 150 lb-ft. Turbo version of the 2.5D.

Same block mounting points, ect.. as the 2.5TD. Aluminum, direct injection head. Intercooled turbo. Built 1990 to1993. The "Defender" version in mostly a straight fit to 90/110/130s or Series. The "Discovery" version uses a different turbo mount to makes it a tough fit.
200TDI, 107 hp, 188 lb-ft

New engine with different mounting points, will still fit Rover trannies. Built 1994 to present. Direct injection, intercooled turbo.
300TDI, 111 hp, 195 lb-ft

Hay spotted you heading north van way yesterday (27 dec), nice looking truck

red90 - Thank you :)

nakedbarra - Yep, I was cruising home from SeaRail on Annacis island yesterday . Thanks!

red90 - So with those exp[lanations, the 2.5TD is the easiest engine upgrade WITHOUT any modifications (if that is possible) ?

So the 200tdi requires some major modifications from the sounds of it then doesn't it.

Cool :lol:

Thanks Swag

Hey there.....

You pose some very interesting questions and the dialouge is interesting.

My first Land Rover had a 2.25 diesel. Was great Off-Road but an embarassment on the highway even with overdrive. That being said I recently bought a Series III Carawagon with a 2.25 diesel with no overdrive and it runs nice on the highway around 100kph. So it you get a good one it's OK!

I have a 1969 Series IIa with the 2.5TD and love the fact it can actually accelerates uphill and with the fairy o/d broke the speedo first time out.

I drove Bill Eastwoods 90 with the 200TDI and fell in love all over again. So I have a 200TDI on its way to replace the 2.5TD. It should bolt right in and just require a few mods around the intercooler issue. The series trucks need a little more room in front but I have seen a great job that Doug Shipman did on a truck in Portland.

As far as a Disco 200TDi, they are the cheapest and easiest to get. Glenn Daigle has one on the way with the Steve Parker conversion "pipe" so well see how he makes out.

When we were in Moab this year I drove a Range Rover Classic with a 300 TDi so I am thinking of that for my RRC.

To summarize it is totally a question of cost/benefit. The cost of the engine and the cost and trouble of installation. Keep it as simple as you can they all can do a great job and diesel in my mind is the only way to go.

Hope this helps...

Thanks for the reply Stuart :) Some great info there.

If you are putting a 2.5TD into a series truck this is what you will have to do.

Cut off RH front engine mount and adapt it to fit. Tranny mounts need to be shifted 1/2" to the right and front mounts 1" to the right so the turbo clears the steering box, also advisable to trim the shaft on the steering box.
The series rad will not be able to keep up with the heat demands of the turbo, it will be ok under light driving conditions, but I advise getting the front grill, hood and rad setup from a defender.

The series tranny is light for the TD, mine had a SerIII bx, with a SerIIA bellhousing and a B suffix transfer case. Also recommand the Salisbury rear end.

The plus side is that this engine makes a 109 5door a joy to drive, lots of guts and great mileage.

Hey StuartL,

When you do the engine upgrade, will you be taking some pics of the entire process for future reference? I'd love to see the before, during, and after pictures, and hear about the entire process :)

Cheers

I can take a ton of pictures when I put my 200tdi into my early 90 if it will help. The disco motor is a bit more tricky than the regular defender 200tdi, but the turbo sit lower, I don't know if this is better or worse for transplant to a series 3. I am not sure if it will fit into a left hand drive as it may foul the steering mechanism, mine is right hand drive so it should be fine.....

Here are some links I found.

Glenn D. thank you for those great links! Lots of info there :D

I will ask Alan Simpson who will be doing the installation on my Series IIa to post some pictures. Glenn will have the advantage of room up front in his 90. I would think between the two of us we should have it covered.

Here is a great site with some good info on the possibilities for an upgrade:

Land Rover Conversions using Land Rover Engines

and this article:

Land Rover - 4 cylinder Upgrades

Apparently the second article allows for some great upgrades to really draw the power out of the four cylinder engines.
