Was wondering if anybody could give me their thoughts on which engine is better to choose - the 200 or 300 tdi. where there that many improvements?
cheers, Adam.
 
if there both standard defender engines the 300 will have about 8bhp more not that u can really tell people say the 200 is easier to work on but i cudnt tell u as i've not had any problems with my 300 other than a split heater hose!
the 300 is quieter than the 200 it still makes a racket tho
also depands how much u have to spend cuz the price of 300's is quite alot i like mine tho :)

Why would he downgrade?

In all seriousness he is probably looking for an engine that he can take care of himself; without needing to carry a laptop! The TD5 is not the hands down winner by any means, it may be the engine for some people but it depends on its uses and where its going to be.

TD5's have a place, for my purposes and many other people I know the TD5 is not the best candidate. You can't push a TD5 down a hill in the middle of a field with a flat battery - or indeed no battery (alt belt removed) and start it. They depend on far too many electrics and as a result its never a simple problem solving exercise.

When it comes to engine choice the 200 and 300tdi are the most popular because they are for lack of a better description: simple.
 
dont touch a td5 all mine did is break down ive now gone back to a 300tdi and its so much better to drive even tho it does make abit of noise i thought it drank less oil that my first landy which was a 200tdi and slightly better on fuel and you can feel a difference in power i think

but hay thats just my thoughts
 
i've had my td5 just over a year now and love it to bits. i havent had any complaints upto now!! (touching loads of wood lol)
 
The engines are virtually the same (despite the "300 upgrades" landrover promised but the 300 is normally fitted to a R380 gearbox which is supposed to be a bit stronger and better than the LT77 (380 is the number of lbs ft it's rated to). Not personally had any experience of the 380 but everyone says it's ok i think - better than the **** they're sellotaping to the TDCi these days apparently.
 
The R380 box was introduced as brand new LR gearbox across the entire Land Rover and Range Rover product lines. The R380 is a radically reworked LT77 (The 1940's Jag gearbox remember) with improved main shaft bearing arrangements that provided an overall strengthening of the box. The R380 name stands for "Rated to 380 Nm input". But the R380 still has the LT77's 77 mm shaft spacing. Since Rover was no longer part of British Leyland the LT prefix was abandoned.

The V8 and Tdi R380 gearboxes have different bell housings and primary input shafts. They will interchange by swapping these parts.

The R380 quickly got a bad name from gear problems and accelerated main shaft spline wear where it mates with the LT230 transfer case.

The LT230 accelerated main shaft spline wear problem had been present on all previous LT230 equipped Land-Rovers, irrespective of the gearbox it was mated to. This design problem was kept low key until a lot of customers complained about R380 problems.

A number of different fixes, such as slingers and special transfer case input shafts have been added to try solve the LT230 problem.
 
newton meters schmooton schmeeters but i wern't far off on the rest! ( a nm ain't massively different from a lbft anyway it is? - three quarters or summat?)

And tonights anorak prize goes to.........:D :D :D
 
i heard the bore stroke on the 200 is slightly longer than the 300 thus giving a fraction more lower grunt ie better for pulling stuff like trailers. I would imagine that it is very marginal though.

buy the best 300tdi you can imo.
 
bore and stroke is same for all the 2.5 motors, petrol and diesel. 2.5 na, 2.5 TD, 200Tdi, 300Tdi are all the same.

ps I thought the R in R380 meant Rover as opposed to the LT which meant Leyland Transmission.
 
it also goes to show in the price you pay for 300tdi's the price is strong still as its the most sort after defender engine.

i belive its got a slightly more reliable turbo on the 300tdi's i dunno if this is true tho any else shed any light on if the turbo's are the same

The 200 is the easiest to work on, the 300 becomes progressively more complex leading up to the TD5 which is the most complex and electronic of the 3.

There are issues over some spare parts availability for the 200 - heads for instance are apparently getting very difficult to obtain.
