ok guys Know the old engine swap has been covered a lot and have read the old threads.
I am interested in a 1969 109" series that is all original with 2.25 petrol in. need a little work. Ideally wanted a diesel but just wondering is it worth buying this for about £600-£700 and fitting 200tdi or better waiting and probably grabbing a diesel similar for around £1100-£1200.

how hard is it to fit engine and how much does it cost if anyone has done it.
guessing need engine, transfer box, ancilleries, wire in golw plugs and all fuel pipes.

cheers and again sorry if there is an exact thread for this that i missed
 
Best to get donor Discovery so you have it all. You will also need Disco rad and a 300Tdi intercooler makes things easier. Head lights in the grill makes it hard too. You could 'de-turbo' the Tdi and make things easier but then I wonder what the point is :)

You will also have to dump the PAS system and relocate the alternator.

BTW, you will have to modify the chassis to fit a Discovery 200Tdi as the turbo hits the chassis because they are deeper on a LWB.

You will also have to make up an exhaust unless you want to spend nearly £300 on a Steve Parker system.

I would start with an early 110 (if you need LWB) with a 2.5TD in it....as that will be easier to convert to a Tdi at a later date.

Andys right.
If you dont fit the turbo, its an easy job, apart from drilling some extra holes and fitting a couple of bolts its not much more difficult than swapping an engine for the same type.
You wont need the gearbox, the 200 and 300 tdi fit the series box.
Why not fit the engine without the turbo then sort that out at a later date, I hear the 200 has more balls than the petrol without it anyways.
I fitted the 300tdi in mine, forget that its a lot of work, the only good bit is the turbo fits.
 
unless you find a 300 for peanuts i can't see any advantage of wanting to fit one instead of a 200 in this instance
 
cheers guys, i might have been wrong with the transfer box but was thinking along the lines of revs, obviously petrol engines can rev higher than diesels and thought without the change may have the diesel doing 4500rpm at 40 mph :p

yes i wouldnt mind the non turbo power doesnt bother me if i wanted fast i wouldnt go for a landy :D just with the price of fuel these days 15mpg is harsh even for a weekend car :)

do the 300 and the 200 require the same chassis mount changes then if fitted with the non turbo, and would i still need to move the lights from the grill to the wings?
 
never fitted a full 200tdi into a lwb but have fitted a full 200tdi into a swb but just how close is the turbo to the chassis on an lwb, on the swb its about 2" with the wings ground off the engine mounts ( on the chassis ) and the tdi was as steady as a rock even when cold there was no movement in the engine and if you rev the engine from under the bonnet the engine only twisted slightly about 1/2" i would say, so if the engine was about 1" away from the chassis you should get away without cutting the chassis out.

200 tdi without turbo sounds like the way to go then and then at later date may look to working on fitting the turbo :). will no doubt run the petrol anyway for a while until i can get a trustworthy 200tdi. cheers
 
this all looks rather scary!
I have a safari i would like to do, but the last conversion i did took 10 months as my back failed, so another 10 month job??
What is the driving experience of a 200 Di ie no turbo?
I like the sound of simplicity, so what is the down side of a 200Tdi?

I would not go taking notches out of the chassis rail in order to clear the turbo on a Disco 200Tdi engine - it will weaken the chassis. A Defender 200Tdi engine is the best solution, but I think quite tidy job could be done using a Disco 200Tdi engine. I know somebody who has installed one of these engines in a series Land-Rover with the turbo on upside down. This would solve the clearance issue on a 109, but would mean that the inner wing and bulkhead support bracket would have to be chopped about quite a bit. If I were doing the conversion I would make an adaptor to go between the exhaust manifold and the upside down turbo which would make it clear the inner wing and bulkhead bracket. I think this would be possible if the adaptor was fabricated using a piece of tubing with a fairly tight 90 degree bend. By the way - the turbo can be 'clocked' to position the air outlet port where you need it.
 
cool, ok know it may seem like a stupid question but as i said i am not concerned with speed too much more mpg as the better the mpg the more i can take out my toy for enjoyment :).... so my question is does having no turbo significantly affect the MPG, i cant see it doing so but just thought I would ask.


ps thats a good idea fenby with fabricating a pipe for the turbo, thanks
 
Personally reckon 112bhp is a bit much to push through series running gear but whip off the turbo and you got a lovely soft tuned, economical motor that gives about 85 horses and turns motorway driving into a viable prospect.
Also you dont need the intercooler and it all fits with the series rad, quick trip to the scrappy for a 'lecky fan and at least the exhaust manifold is pointing in the right general direction.
Got one in my series 3 swb and in the process of doing the same to my 2a lwb...200di's.....love um!
 
My 300 tdi has totally awkward mounts, but the turbo is a lot higher up, and the 2 halfs of the turbo are clamped and can be undone and rotated to a convenient position for the intake/exhaust to route to.
Also the exhaust fanimold has a reasonable take off angle.
I've wondered a couple of times, and I think it would work, to put a inlet/exhaust manifold and turbo from a 300tdi engine onto a 200tdi, it'd be a lot simpler to fit and as long as the manifold fits the head stud pattern there'd be no need to bash silly holes in the chassis, fenbys quite right, you dont want to compromise the strength of the chassis esp at the front.
