A V8 rover engine will not bolt to the current gearbox. It is meant for the rover four cylinder engines. You will need one for the V8. LT77, R380, LT83 or LT93.

To add to this. V8 manual boxes are hens teeth in the USA. Autos are easy to find.

I've been shopping. That's all I know. Asking people who would do the work for me, and at the various places I've asked, I've had a pretty consistent quote of $3-5k worth of work to swap gas to Tdi after you buy the engine, ancillaries, and exhaust. (Total of $7-10k)

But I'm ignorant of what it really means to do the conversion, I was only asking about the price in the past. With the $$$ amount being that high, I always assumed there was a lot of work to do other than simply mounting the engine.

Although it's something I've always liked the idea of, I've not gotten really serious about it because of cost. Maybe I'll do specific research if that's really all it takes.

Not wanting to hijack thread though.

Maybe I'm off base here, but couldn't you find a beat up Discovery I with a 3.9 or 4.0 and manual transmission to scavenge the engine/trans from? My back up car is a Disco I 4.0L/r380 5 speed that I picked up for $1800. Runs great too. Another plus is that you get a free set of wheels and some spare door handle trim if your truck has roll up windows! And you'd be keeping it Land Rover.

I think most of the 3.9L manual trans Discos had the LT77 so if you want to get an r380 you'd be looking for a 1996 with the 4.0 GEMS motor like mine. '96-'98. Positive aspect of the earlier 3.9 is that there's less computer-ness to it (it even has a distributor).

Last benefit is that you'll get horrible mileage like me!

I'm thinking that this is probably the way to go. If I could get 15 or so mpg I'd be satisfied.

All you gain by going with a Disco drivetrain is not having to buy the transfer case adapter. You are getting a 20 year old worn out drivetrain that are not well known for lost life.

I'm assuming the OP is doing the work himself, so install labour is not money. The "easy" swap I mention is 12 hours labour if you have not done it before. It is a simple bolt in job designed by Land Rover to be easy to convert on purpose.

The "harder" TDI swaps are at least double that time.

Not sure what TN laws are about going from gas to diesel, but the easiest/cheapest option by far would be the 200tdi swap Red90 mentioned. The OP could source and pickup a 200tdi from Urban for under $5k and have it in his 90 within a weekend. No messing with the engine mounts or tranny/geabox. For a 90 a good 200tdi should be plenty of power. And anything needed for the swap is available as an OE piece. I would do a Robert Davis method of Sedimentor->electric fuel pump on the fuel line as well as take out the petrol filter and swap to a diesel one. Looking at Urban's site - it looks like he sells the 200tdi with all the small items so cost could be $5k flat and a hell of lot less labor hours.

So the ideal of dependability is what started this whole 4.3l vortec thread. What I want is a gas conversion. I want to keep a manual. I've had projects before and know that if it's time consuming and requires a lot of engineering, the project gets lost, years go by and I don't get to enjoy the vehicle. I've done this several times and ended up selling off the project before it's done. I've wanted a defender for a long time and and finally bought one. The downside is that is has the 2.5l petrol. The upside is that is has A/C installed already. I just want dependability and a little more power, not necessarily 300hp, but a little more than the 80 something in it now. I'm looking for an "easy" swap that others have already done and have some sort of "swap kit" to do.

Other than not wanted diesel (why don't you want diesel?), the 200TDI fits the bill. I've done one in my garage by myself in a relaxing weekend. 115 hp out of the box and easy to get 150 hp. 25 mpg. Cruise at 75 all day. Dependable and easy to work on.

Absolutely nothing else is an easy conversion with a kit. They will all require some amount of fabrication.

Diesel is not easy to find like gas where I'm at. Gas is $2.40/gal and diesel is $3.80/gal here. You say 25mpg, but diesel is 60% more than gas per gallon here, so it's really comparable to a gas engine getting 16mpg. MPG isn't the measure of comparison....it's MP$. Just don't want diesel.




I'm reading more into the GM motors with the NV manual trans. Could be an option for what I want.


Landy Andy...when's the last time you drove your defender?

Then I agree the Gen 3, NV4500 is the best choice for gas. Plan on a $5000 budget and 40 hours install time if you are well organized.

Landy Andy is doing a complete truck build from basically ground up, not just the engine, so that won't compare to what you want to do. http://www.defendersource.com/forum/...ad.php?t=36827

I have yet to figure out why diesel is so costly. When I did my conversion, diesel was cheaper than regular. At today's prices it cost almost the same to operate my TDi Disco as it does to drive the RR.
Granted I get my gas at Costco for the RR.
I wish Costco had diesel.

Since the 2.5 petrols and diesels share the same block...could you put the diesel turbo on the petrol engine??? I've heard of people taking diesel turbos of ford 7.3l diesels and putting them on their 351 gas engines.

There are two reasons. First diesel is more expensive in the winter due to heating fuel demand. It drops a lot in the spring. The second is that fuel tax in the USA is higher on diesel than gasoline.
