series iii 109 station wagon engine and box conversion advice

Hello all New to the forum ..

I have just got a new landy to the growing collection its a 1973 109 series 3 station wagon in pretty good nic but the 2.6 6cyl engine is knocking and doing about 10 to the gallon ... not good

i have access to several possabilitys for transplant .

Ford v6
300tdi
200tdi

Im opting for 200 tdi but as it being a 6cyl originaly the box bellhousing is differnt and will have to be changed

thus :

Will a lt77 out of a 110 fit into a 109 without too much messing about ?

I have also a r380 and an lt77 out of a disco which would be the easyest option ?

what ever yer put in if its perm 4wd yer series front axle wint like it as the have uj's whereas the perm4wd axles have cv joints

Im Presuming that it is as its out of a 1990 ish defender. If there is not too much messing about with propshafts i'll invest in the center diff modification from ashcrofts

changing mounting points isn''t a worry just there isnt a lot of info on gearbox conversions

i am going to fit a 200tdi with either an R380 or a lt77 from a disco but i am going to replace my axles with discovery ones wit cvs rather than ujs

is it possable to use discovery axels on leaf springs ?

you can if you get conversion plates made and weld them to the axle, i am getting some done soon, there will be a thread on how to do each job as i do it

Converting a Series Land Rover to a 200 tdi engine

Was the engine just knocking? Or was it blowing smoke and stuff. My 2.25 was missing really bad earlier this summer and a new distributor cap, rotor, and wires made it run like new. I don't know much about the 6 cylinder engine though.

The 2.6 litre engine was a combination of an overhead (inlet) and sidevalve (exhaust) engine, a great engine design for the 50's, although its roots started in the 1.6 litre OHV/SV 4 cylinder of the late 40's. The cylinder block around the exhaust valves seat is prone to heat cracking allowing the valve seats to become loose, break up and damage the piston/head.
