Thread: 3.9 V8 petrol versus TD5

We should get together. We could almost build a car... But I sold the transfer case and the XYZ. I still worry about that last decision...

The D2a lever also pretty much canned all of the other aftermarket CDL solutions manufactured by LR specialists. Davis Performance had one which locked CDL when in low range. AMV I think had a electric version made with a windscreen wiper motor to activate CDL. I hadn't seen your one before with the 2x forward/backward levers. Another mob had a shaft come through the centre console that was connected to the CDL spigot, and you twisted the lever to activate CDL. I'd also been sent a pneumatic ram operated one which I really liked, it probably just used an airlocker switch. Some also just got under the Disco with a 10mm spanner too.

I had one of those AMV ones here. Gave it to the member who bought the transfer case I had. My D1 has a MaxiDrive locker. Something like the operation of that could have been used I guess.

I figured the D1 one would work. An LT230 is a LT320 after all. Hadn't thought of the NVH issue, as in my D1 the CDL lever is the least of my worries on that front

Having owned a 95 D1 and 01 D2 at the same time for many years I have to say there is no comparison between the D1 injected and the d2 injected V8's - from economy, torque, power, driveability, smoothness and reliability in terms of spark at least. The D2 in manual guise gets very very un V8 like economy especially on highway runs fully laden. 13 to 14 even with roofrack and gear on it on the highway is quite normal for the manual. The difference between the D1 3.9 and TD5 in economy would be quite marked. These days I would chose a Td5 over a D1 V8. For me I would be hard pressed changing from my 4.6 D2 to a Td5 but i might do it if i was doing a lot of touring in desert country etc. In my view a D2 is a considerable step up in 90 percent of ways over a D1. D2 had a wider wheel base and is more stable. D2 is much stronger in a colission. D2 has far less rust areas. D2 is more refined. D1 has more character and more xompliant suspension tune but all that goes out the window when aftermarket suspension is thrown into the mix. The pre facelift D2 is easily retrofitted with CDL (even with no internals all you need is output housing with internals and you can easily install a basic push pull T piece on the trans tunnel or go the whole hog with a proper shifter,).Cheers

I probably have any bits you may need

ive never driven the D2 V8's, are they really that different from the 3.9 D1?

i think from a fuel economy stand point, my 3.9 wont compete with the TD5 or anything for that matter, it is indeed, thirsty.
my biggest struggle is the D1 i have is in mint condition and im simply just attached to it. i must say, from a cosmetic stand point, i do prefer the shape of the D1 too.

hypothetically, if i was to pass up buying the D2 TD5 id save 15k - are engine conversions a viable option then?
(there use to be a D1 near by with an LS in it, probably had the same fuel economy as my 3.9 but damn it sounded so good)

I don't think a D2 is fiveteen grand better than a D1. I don't think any D2 is worth fiveteen grand.

If considering spending money on an engine conversion, why not keep D1 and buy the D2 for touring. Engine conversion would be at least 15K. On subject of conversions it's becoming popular to put the Td5 in a D1. Great tunable engine that sound fantastic and still return reasonable economy.

I agree Ian. And to think that a Defender is worth upwards of 4 or 5 times that is even more insane. Cheers
