Isuzu Engine Swops for Dummies

While the generosity is flowing, I should point out I'm happy to be an off-road test driver if you need someone to see if it can handle the Aussie bush. My fees are reasonable. :ohyes:

Sounds good. Perhaps I should just leave the defender at yours entirely then, just use it on my visits to Australia then. Could get you to exercise her on a weekend basis, for a nominal fee of course :p

Good work, and good write-up Mike.

That's interesting, because when the 4BD1 was running in the Rangie, it was one of the quieter ones that I have heard - Vern can back me up on this one. I was concerned about engine noise prior to purchase, but it seems like I've gotten lucky in my engine choice???

The turbo does seem to quieten them down a bit.

Turbos are the best thing ever for diesels.
Muffles intake noise.
Muffles exhaust noise.
Preheats the air to quietn the combustion noise.
Provides a nice whistle.
More power, more torque.
More efficient.

What's not to like?:cool:

Throttle response sucks compared to an NA engine but I can live with that :D

mmm, rick you haven't driven a 4BD1T yet then?:cool: My NA engine 'now with kompressor' throttle response is the same as before but now with 40% more torque added:twisted:

I've recently (last week) gone back down in turbo size. I'm again running a T25 with a smaller compressor wheel than a 300tdi. Boost response is excellent.
To get the same torque in a NA engine you'd need about 8 litres. Isuzu do make those too.:D

Wow, An impressive read, and quite a staggeringly generous response from the people of AULRO. Good to see!
Hope you get it up and running soon, I can definitely see an Isuzu county project in my future.
That's if I don't have to spend all my money replacing the windows within a 5km radius of my house after my mothers shriek of "You bought WHAT?!"
:lol2:
Nice work, best of luck with it! :cool:
Cheers

OK, I'm just comparing a TD42 to a TD42T which at one time I was jumping out of one, into the other, then a 300Tdi :( (then something with a 6/354T Perkins :D)
