Thread: 200tdi or 3.9 Isuzu......

compared to a 200TDI?

wear in the drive train downstream from the motor...

the 4BD1 has torque to spare, has more power, it's bullet proof, similar efficiency and lasts longer!

on the downside it rattles more and is noisier too!

If you owned a 4BD1 you wouldn't need to ask

The advantages of the Isuzu compared to the 200Tdi are mainly durability and reliability, with the addition of better low down torque and driveability. (not that the 200Tdi is bad on any of these, although the Isuzu is likely to have twice the life).

The down side of the Isuzu is the vibration and greater weight on the front wheels, which can lead to wear on some front end components and on the gearbox and transfer case.

That pretty much covers it.

On the matter of gearboxes...
The LT95 4-speed has no problems behind an ISUZU. IME the LT85 5 speed last as well behind the isuzu than the LT77s does behind the 200tdi.

Quite a few people have fitted late model R380s behind 3.9s and they are working well. A couple of people on here have ISUZU boxes, but this isn't the world's easiest conversion, as the box is cable-shift, and you need a serious spacer between the box and the t-case case.


But the bottom line is - drive one and you will FEEL the difference Both in the seat of your pants AND in your teeth

EDIT - p.s. - whereabouts in Dayboro are you? Know anyone with the surname Chambers?

Thanks for the advice, the one I have in mind to purchase has had lots of $$$ spent on drivetrain, axles etc. Until it's on my drive I'm keeping quiet about it though, don't want it to fall into the wrong hands although the deal is as good as done.

isuzurover, I can't say I know anybody with that name although I might know them by sight.

Hang on a minute, I thought Tdi's had slightly more power and torque than 4BD1's. 4BD1T's are a different story!

when all stock the TDIs all have it over the 4bd1 in terms of max torque and max power......

however that doesnt tell the whole story.. Its the way that the isuzu develops its torque that counts its sort of like comparing a well tuned 2.25 to an old holden 6

sure the holden 6 has it all over the 2.25 BUT....

well tuned and setup the 2.25 starts making usable torque at 500RPM which is conveniently 100 RPM lower than idle.

The best Ive ever seen was a petrol 2.25 5 main that Idled at 300RPM as smooth as butter and would if let up easily on the clutch walk around at those RPMs...

you pick the engine for what you need it to do.

If you want to tow or go off road and you dont mind slow but Must have reliabilty you go for the suzi pushing a 95 if you want it to be faster and can deal with a degrade in low end torque and slightly more expensive maintenance and the potential for more breakdowns then you take a tdi pushing and 85 or an r380. the tdi is marginally more fuel effecient

the TD5 bridges both these motors offering more go more torque and more fuel effeciency but you pay for it in maintenance..

just IMHO...

I think there's a better supply of spare parts for an Isuzu, too. Things like cyl heads for 200tdi's are virtually impossible to find, even 2nd hand.
