200 tdi vs 300 tdi

[bigcarle]

hi maybe this has been coverred in another thread that i havent found as yet, but what are the differences between the 200 and 300 TDi diesels?:excl:.
i am going to put one in a 1987 RRC hiline and i would like to know more about the 2 engines
thanks in advance

Basically the same engine, but the 300Tdi is supposedly the more "refined" one. It developed out of its predecessor mainly to satisfy more stringent emission rules i Europe (and probably elsewhere). Most ancillaries are not easily interchangeable between these two.
The 200Tdi will be a straight fit to the LT77 and the 300Tdi to the R380. The 200Tdi apparently sounds a bit more rough and has a few hp more (probably depending on state of fine tuning). Spares for the 300Tdi should be easier to obtain.

Hope this helps! Happy Easter!
Cheers

G'day bigcarle :)


The 300Tdi was a quieter and more refined version of the 200,and with better emissions for the EU market,front part of the engine is different,but should still adaptable, if your 87 Hiline has an Auto, it is the same ZF4HP22 as in the Disco 1 and should be a straight swap transmission wise.



Happy Easter Jojo :D


cheers

Defender derived 200Tdis were different from Disco versions.

300 Tdis were the same across the range.

Some parts are cheaper for the 200 Tdi, such as alternators, but some parts are no longer available, such as heads. Apparently a 300Tdi head will retro fit to the 200Tdi.

The 300Tdi is quieter and has a bit more power.

The 300Tdi was produced for a longer period, and is still in production for some military applications, so new and 2nd hand parts will be more plentiful.

300Tdi are more susceptible to timing belt wear, but I think that this was due to a poorly designed system. The retrofit kits all include the improved pulleys and revised tensions. However, given the timing belt scare early in their life, all 300Tdis now get regular timing belt changes (at 60-90K depending on who you talk to). Having done 4 timing belts on different vehicles, I'd comment that the early ones were pulverised and shredded by he time we changed them, but the latter ones still looked like new, suggesting they may actually last a lot longer with the new timing belt kit. But I wouldn't risk it.
