Fit a 4.2 EFI Toyota engine in a Defender

Sluggish TD5

have you given any thought to updating the computer chip, done correctly you can gain up to a extra 40kw of power, and then blow away the landcrusiers, easier and cheaper than changing engines :wave:

Go for a chip and intercooler upgrade.

In theory yes...and maybe in the cold UK......I did the chip upgrade thing ...as well as the intercooler upgrade....and the upgrade looks impressive on the dynamometer ......BUT both still do not function as well as large capacity normally aspirated diesel engines....Particularly in hot conditions in Africa where I live ...the engine revs ...are higher making the engine hotter...making the ambient temperature arround the intercooler higher reducing its effectiveness (together with the hot air intake)...also hellish hard on the turbo and engine itself...I have first hand been on trips with Landcruisers where they were pulling and carrying more than me and yet cruising at 30-40 km faster than me!!! Furthermore their cruising was less of a strain on their engines etc .....Travelling for 80-90km an hour for 8-10 hours at high revs seems ludicrous compared to 120km at lower revs... :drive: :drive:

I see your problem, one solution - do not travel with cruisers ???

How about putting the TD6 of the new Range Rover in a Defender? Or the TDV6 of the LR3 (Disco III)? Both of these are smooth and powerful engines. Of course, they may be too expensive. How about some type of Mercedes diesel? Try to stick with European quality.

Fitting a "foreign motor", toyota, mercedes, whatever, still leaves you with sorting out an adapter for mating the engine to your gearbox, not to mention engine mounts etc = headaches.
