Thread: D2 TD5 vs Fender TD5 Performance

Basically exactly the same engine year for year, only difference I can recall is the wastegate is electronically controlled on the D2's which it isnt on the Defender.

Power difference is just down to the ECU Map.

The Auto D2 has more torque than the manuals.

250lb/ft as opposed to 221lb/ft.

Td5's can be chipped to much higher levels.

So why would LR want the Defender to have less power?
Will the Defender run on worse quality fuel or something?

Surely it is in their best interests to have as much power as possible in every vehicle.

Defender is also lower geared. The Auto D2 gains about 10% extra from the torque converter.

I had initially heard it was due to the induction architecture when fitting the TD5 to the Defender body.

But when I found out that they dont run the boost modulator - which I suspect is for remote reliability reasons, then I understood it to be due to lower peak boost pressures than the Disco. The modulator automatically winds back the boost as I understand it when things are getting a little to warm for the motor.

Mind you, the Puma TD4 is still only about 90kw, so it does make you wonder.


Re performance, I'm not sure when a Defender would be faster. They are heavier and blockier with the same motor with less power.

well mines is bog standed an non chiped, only the exhuast has been done an it has made a huge diff to going from 80-110, in 5th an put ur foot down it pulls very well, get past 110 an its still pulling (not that iv ever done that)

iv driven alot of other defenders an find mine still pulls the best idk why it dose an other people have driven mine an say it pulls very well,

i must of got the pick of the bunch

I recentley purchased a flashable ECU ex a Defender with an upgrade.
Fitted it to my D2 and it did work.
It was too harsh in power delivery,all or nothing as the turbo modulator wasnt operating.
I had it re-set by the vendor to fix a few issues,ie Turbo Modulator,SLABS computer.It smoothed it out nicely.The aircon,cruise control,temp gauge were all re-instated.It made the D2 MUCH more driveable in traffic,almost like a new vehicle.It was only marginaly more powerfull where I need the power boost most,highway and towing,it did hang onto the boost better,so Im guessing was up on torque somewhat.
I sent it back and its had a better D2 map fitted which Im told will increase hwy/towing response.Its due back any time now.

Is there any particular years that are better than others, and worth spending the extra $$$ on? Or is km's more important?
