Thread: Series 3 Engines

The one I could get turns out to be an Iron Duke, Damn Yanky imposter.

Another alternative is an isuzu 3.6L 4BB1 Not quite as beefy as the 4BD1 but a bit less vibration and noise.

Is the vehicle, or was the vehicle originally 4cyl or a 6cyl ?? if a 4 cyl series 3 I would definately recomend that he use a 4cyl 2.25 Landrover motor, the big question is what is the Series 3 G'box like as they did not hold up very well behind a Holden Motor if the G'box is iffy find a 2/2a g'box as it is stronger, then fit a 200 TDI without the turbo, they will fit straight into a series matching the mounts and only differ by one bolt hole on the bellhousing, that will give you good power with out the need to turbo, remember that the Series 2/2a gearboxes are stronger that the Series 3 ones as they changed them somewhat to be able to fit the 1st-2nd syncros in to them.


The same can be done with the 6 cylinder chassis, just that you have to reposition the motor mounts, there is adifference in the bolt pattern on the bellhousing, 4cylinder bellhousing has the top bolt hole in the 12 O'clock position, the 6 cyl bolt holes at 11am-1pm.

bolt the motor to the gearbox and suppend it, then mark the position to re-locate the existing engine mounts.

Its looking very iffy at the moment. Owner has left town owing money to the workshop. So far its sat for over 12 months and the workshop wants $1700 for it with out the engine. They have also removed the gas tanks from the sills. They claim the engne is in the shed but is useless so he can have it but it will need replacing. I know the aprentie was willing to just give it to us.

$500.00 to him now is surely better than $1700.00 never

Uncle Ho, this is really interesting. I've been reading a little about conversions, and there didn't really seem to be any decent ones, especially for the 4cyl. So it sounds like the TDi is basically bolt in to a 4cyl series. The bolt in the bellhousing - is it needed or should it be modified to sort the problem? Also, does the turbo produce too much power for the gearbox or are there other reasons not to run it such as intercoolers etc. Is it a normal series clutch that is used?

200 Tdi into series would be fantastic, but I would leave it turboed. The injector pump is calibrated differently to a NA pump, and is quite different. The intercooler and rad should still fit the front of the series, after all, isn'nt the frontal area the same as a 'fender? and if you are worried about the destruction of nthe gearbox, isn't the early LT77 a bit weak anyway? You could also wind the fuel back a little, you should get about 38MPG by doing that anyway!
Find a donor 200 Tdi defender, so you can get all the bits. A disco is no good, as the 'fender also has a different shaped timing case; it is angled down more, the engine then becoming narrower to fit the engine bay easier. and the turbo and intercooler are different too, the turbo on the ;fender is above the manifold, and the intercooler inlet pipe is a slightly different angle.If I was to do this, I couldn't think of a more suitable engine, and it is all LR!!

I stand by my opinion that the best repower for a Series III 109" is a Chrysler Hemi 6. Want to argue? Get your facts very, very, right.
