Thoughts on Transplants- 300Tdi vs. 3.9 v8

By the way do any of you guys know anything about the 2.5 Diesel XJ Cherry?

In North America we got a 2.1 Renault diesel powered XJ in the late 80s, early 90s IIRC. By all accounts it was a dog of an engine (slow).

The 2.5 was RoW only so I don't have any experience with them. The magazine articles I've read seemed to like them. Mid 30s mpg (Imp) IIRC.

I don't recall the manufacturer of the 2.5, may have been VM?

It was a 2.5 VM yes. That makes me worry but also makes me interested. It's a good engine but an utter pig to work on - did very well in the GM Vauxhall/Opel range.

What is unkown is the rest of the drive train as it's the non quadratrac set up. I think it's the same as the Wrangler 5 speed with p/t 4wd. I know the axles are ok, the rear is a Dana 4x4 with LSD the front is a high pinion D30. Ride height is 1.5" over the 4.0
So it's the Aisin-Warner AX15 (?) and an NP231 COmmand Trac(?)

I like the style of the XJ - ok it's for my wife and they are cheap over here - it looks like a family of five would fit well

The rest of the drivetrain is pretty bulletproof with the possible exception of the rear Dana 35 if so equipped. The automatic that is used should be a Aisin-Warner AW4 (pretty much same as Toyota/Aisin A340). The XJ was available with the NV242J in NA also... not sure about RoW.

When talking about XJs

NV231J := Command-Trac
NV242J := Select-Trac

You can tell Select-Trac from the shift pattern: 2WD - Full-Time - Part-Time - 4 Low.

Full-Time is "Merkan" for AWD. Part-Time is Merkan for 4 High. Command-Trac doesn't have the FT/AWD setting.

Hello Everyone,

Sorry for hijacking this threat but I have a question which I hope to get several opinions on.

I currently moved to Miami, Florida. I'm playing with the idea of buying a 1997 Land Rover Discovery SE7 Manual transmission with good mileage under 100k and do a transplant with a 300tdi engine. Getting the 300tdi with the transmission is not hard since I own a 97 D90 with 300tdi back home in Panama (god i miss her and impossible to import) that its in great condition. I know that Ill have to pay for shipping plus labor since i don't have the space, time nor tools to make this conversion. Any one out there knows a good/reputable place in or near the Miami area to make a conversion like this? I will also like to know the legal side of making this possible since theirs tons of regulations that cars need to pass... The USA is a great country but not been ably to see Nissan Patrols, Land Rovers or Fj80 with diesel engines around is a bummer.

Thanks

If you have emissions testing in Miami you probably won't be able to convert a '97. Not without fair bit of extra work to fake out the OBDII system.

What about one of the 300tdi's equiped with an OBDII system? They do exist. I keep thinking this is the way around that problem, but I never hear anybody talk about it. The OBDII is really simple, I think it only checks EGR function. So I'd think it would be possible to get it working and talking on the OBD port?
