It will clear. You'd probably want to run the Dodge NV4500 with the short tail housing. The Chevy tail housing is a couple inches longer and things will start getting a lot tighter at the radiator.

Nice work

We do this basic same thing often in Cruisers. None of it is all that difficult it is just expensive. We spent some time measuring Cruiser vs Rover to see about dropping a 300 tdi into a cruiser, the distances are very close.

The key is the TC adaptor. I think a TLC late model case would work great on the back of a 4L60E dumped into a Defender. Size and output is about right.

I think it will be the other way around. People will want to dump this setup into their cruiser. Besides the fact the lt230 has thicker gears than an atlas, the cruiser transfer case low range is like 2.5 and the lt230 is 3.3. Yes, you can get lower gears (3.1 I think) for $$$, or you can pull great condition lt230s for $250 all day long.

Accessory Brackets

Ok, I will continue to post more updates.

Pictures of the accessory drive. Utilizing the GM P pump and alternator.
No modifications to the steering box.

Okay, I'm an LS ignoramus.

The old 265-400 motors I can tell you all about but not these newfangled thingamajigs

Which version of an LS? is that?

I would imagine that an all alloy truck motor might be a good bet, but I just don't really know.


edit...and I presume the AC compressor fits on there near where it sits on the '97 too, eh?

Thanks,

Keith

This is a 2012 LMG (5.3L, cast iron block, aluminum heads, truck motor) from a Yukon. It has variable valve timing and displacement on demand. 320HP The LC9 would be the aluminum version of this truck motor.

I didn't use the GM A/C compressor. I made brackets that work with the stock Sanden compressor. Just changed the pulley to serpentine. So you can go with stock A/C, no A/C, or use the GM A/C compressor. (GM compressor mounts down low on the passenger side of the block and uses a separate belt)

I will post a picture of the A/C bracket tonight.

x2 I am not familiar with any LS engines. Do any of the LS engines able to utilize the existing R380 manual transmission, LT230 transfer case, steering components, cooling, charging, intake, ignition, driveshafts etc etc etc from a NAS Defender? All I want is an engine upgrade/conversion.

Thanks Nick,

I'm noodling on this for my '97 so it's already serpentine.

I'll have to start keeping an eye out for the LMG / LC9 locally.

I presume we want the 4wd version of the 6L80E, yes?

...off to google the weight difference

Right, it has to be the 4x4 6L80E transmission. The 6L90E won't work.
There are 6.0L (~358 HP) and 6.2L (408 HP) engine choices too.

Any sort of luck getting these to be OBD2 compliant, IE not throwing a code in my D2?

You had to open that can of worms.

While this fits in the D1, Defender, and Classic, the wiring in the D2 is more of a challenge. The D2 has a BCM like the P38's BECM. (Body Control Module) I need to sit down and work out the minimal interfacing required.

As far as OBDII, this uses the GM ECU and TCU with its' own OBDII connector. Easy for the Defender as the 14CUX/GEMS is removed with modularity.
I am not sure if I will have to interface the CAN busses between the D2 BCM and GM ECU yet. But that can be done with a programmable CAN bus router. Not ready to go there just yet.

Regarding throwing codes. You can disable what you don't need in the GM ECU/TCU.
We are still working out the CARB issues of the "engine change" in California. Although, I am using Magnaflow 50 state legal cats. You guys will be the first to know when I get it past the DMV referee.

I appreciate the response! The last thing I want to do is throw another Rover V8 in my disco.

Basically everthing forward of the transfer case gets replaced. You keep the LT230, drivelines and transfercase mounts. The LR steering box stays with the addition of the GM steering pump. The current conversion only supports the 6L80E auto box. As one of the others pointed out, the NV4500 might fit. (if you wanted to stay manual gear box) That still has to be tested. Also, the Y-pipe gets replaced. You would be able to keep your cat-back.
