Muppett Question

[Graham Thomson]

Sorry if it's obvious..........

Somone like Les or Western will jump in here and explain in detail but basicly the 300tdi is a little more refined than the 200. The later 300s have a basic ECU and all the 300s have modern pullies (not V belts) They are about the same power as the 200, a tiny bit quieter (apparently), the air filter is in a different place (on the right of the vehicle on the 300) and the oil dip stick is in a different place (Front centre on 300 instead of right side of the engine as you look at it on the 200)

The water pump is also in a different place and to change the cambelt on a 300tdi, it is alot easier than a 200tdi, as the 200 has to have the water pump taken off.

However, they all say that the 200tdi is the stronger engine

[Scotian]

Just remembered. The 200TDI from the Defender is a few BHP less than the 300 and the turbo is in a different place and a few other things are different . But I dont think the Disco 200tdi has those differences.

[western]

actually 208 improvements/differences between the 200TDi & the later 300Tdi.

defender 200tdi has the high mounted turbo similar to the older TD engine, this was done to give the engine a longer less stressed life for working vehicle, the Discovery version has the lower monuted turbo & slifgthly more BHP/Torque to suit it better for Disco/RR applications as private vehicle, in '94 Defender got the 300TDi/rear disc brakes with the same bhp/torque as the same engines in Disco/RR. various details on/around the engine were changed & EGR/EDC appears on certain vehicles, 200Tdi is EGR/EDC free

[Guest diesel_jim]

200's and 300's (and 2.5 TD's and NA'ds) all share the same main bearing shells, and more or less same crank, so i dont think either is any stronger than the others.

some of the very late 200's also had a serpentine belt like the 300's do.

[Phil Hancock]

Make that late NAD, early are the same shells as the 5brg 2.25. No serpentine belt on 200 shown in either disco or defender parts books.

[JimAttrill]

300tdi has a redesigned front end of the engine including a much better oil pump arrangement. As above, the 300tdi has a serpentine belt, much less fiddly front end altogether. Some 200Tdi parts are hard to get now, including cylinder heads which are made of unobtainium. Luckily the 300Tdi one fits.

[Scotian]

Anyone want a good 200TDI cylinder head? I've got a spare 200tdi sat doing nothing with a bust piston ring and scored cylinder... everything else is perfect and its the fastest engine I had.
