Conversion to Diesel engine

What is the best and straight forward way to convert from a 2.5 L petrol to diesel. Is better to go 300 tdi for the horse power? I have a 1988 RHD 110. Also best source for rebuilt or new engines. Any suggestions or advice on conversion ?? Thanks

yes…seek out the GM ls thread, it's loaded with info…

You end getting close to the same mileage, parts are common and it's really not that much more work to install

I like my 200tdi and wouldn't consider doing a V8 swap.


The "best" choice sort of depends on what your expectations are. If you like quiet and fast, then go with the LS. Better yet, sell your 110 and get something else!

A 200TDI Defender engine is straight swap with no custom work and is an easy bolt in job. Any other engine require various amounts of custom work.

I'm sorry, the 200-300TDI's are turds…I have one

It's not about going fast, but having a reliable engine. We put a LQ4-TH400-series tcase in 109 hybrid that used to have a 200TDI, absolutely no comparison... It's not a race car, but now gets 23mpg, has all the power needed to pull his trail trailer or bike trailer and is manageable, but a beast off-road…

Yes, it is more work, but there is absolutely no comparison to a 300TDI. All about being traditional and holding true too the 110 spirit…but it's called reality

I was in a 300TDi with an uprated Allisport intercooler and an Allisport VNT Turbo from a couple days ago. Frickin' thing had CRAZY power, and it was loaded with rack, tent, winch lots of extra weight... 70mph on the highway was a breeze. Lots of giddy -up and go. Really impressed with the improved power with that upgrade, no comparison to the truck pre-mod.

yep..I'm sure, you can build any motor up…200's 300's, LQ4's, LQ9…but your gonna be into the same amount of cash with a built 300TDI as you would a basically stock LS (LQ4 or LQ9)…

your talkin' 3k for the inter-cooler and turbo...

My 200tdi will go over 80 mph on the level, and I average 26 mpg in mixed driving. I haven't adjusted boost or fueling over stock because I've seen no reason to do so. It has also been very reliable, I commute in mine daily.

I'm not knocking the LS conversion at all (although I despise automatic transmissions) but I think the term "turd" is better reserved for the 12j engine.

I don't think my 200Tdi is a turd. It rolls a little coal and does just fine. Am I racing a chipped Powerstrok? No. But it has great torque and power for the trails and I get down the highway as fast as the truck is designed to. So it is all about personal preference.

Mine will do 80 (with the 1.2 higear tcase)…averages 24mpg…and I own one so I can call it a turd

Your right about "it's personal preference" and I just don't understand the infatuation with the LR diesel's. If your 110 came with one, that's different, but to swap one and not look at other options is short sighted. I've driven this truck with both, so I can say with "actual" experience, that if there's a choice, I'd go LS everyday, anyway and any way…



Also, I was never a fan of this, thought the same about going fast and shit, but it is a seriously awesome upgrade for 110...

Zero money needed to tune up a TDI. Just adjustments. Maybe a little to buy an EGT gauge, I suppose. Should be able to do 90 mph. Never will be fast, but does the job. Should cost less than other options as well.

After the post apocalyptic EM pulse you will wish you installed a one wire diesel instead of an LS motor.

So the OP needs a motor, by the time your done getting a motor and all the other bit's to "DO IT RIGHT" your in for about 7k (If you do the work yourself, closer to 9k if you get a "Turner" block).

You can do a LS swap for about 6.5k, that's a real world cost, including transmission adapter, wiring harness, ecu programming.... Not speculating, this is what it cost to swap a LQ9-TH400 into a 109 hybrid, that basically is a 110.

Like I said, I don't understand the infatuation with the LR diesel's...

You aren't pricing in labor for either installation, correct? Besides, a used Disco 200tdi would be closer to 3k.

If I have to explain it, you wouldn't understand.

I was $3500 all in for my TDI conversion. One lazy day to install it on my own.
