Got them on my LM7, great quality

With those and the car intake you'll clear the bonnet no problem.

Nick,
Do you have prices anywhere in this post or a website? I'm looking for some information on the kit. Planning on putting a LS motor in my 2004 D2 soonish.

GM Gen 4 conversion including LS

(Ashcroft Transmissions)
Aschroft says, "This ratio is usually only adviseable for those vehicles with Portal Axles or large diesel engines." Would that include LS Engines too?

Or would it be easier to just ditch the 22D 1.410 ratio LT230, and instead buy and install a Disco 1 V8 1.22:1 ratio LT230?

Here is a survey question: please let us (or PM me) know what LT230 you'd install, or would have installed, or have already installed in a Markiw GM Gen IV LS Defender conversion:
•1.003 ratio
•1.211
•1.222, or
•1.410 ratio

D2 had a terrible motor, at least when it went to 4.6 liters. Cracked blocks, slipped liners, oil pump failures, head gaskets, DEXCOOL damage, etc. Take a look around the D2 forums. If they put a good motor in it, 90% of the threads would be about driving the cars and the rest would be three amigos / braking issues.

This is an LS specific thread, take the D2 debate elsewhere & don't pollute the thread... That's

OKie Dokie…seems I don't know shit and thanks for enlightening me on the shortcomings of Land Rover motors. Can you please link me to the threads so I can research what I can expect for my D2 motor when it fails. Please go to Dweb and start a thread there, as this is a mainly a Defender site and this isn't the place for discussing the obvious shortcoming from your vast experiences…


I already apologized for polluting this thread with D2 bullshit

Back on topic, I'm planning on running a 1.4 t-case behind my lq4-4l80e buggy…turning 37's

don't be, it's not that impressive…I'm running that t-case on my D2 right now with 37's and believe it or not, a stock 4.0 D2 motor that hasn't self-destructed. Can do 80 all day long, but like with any lifted truck, it's not built for speed...

E-Rod

Currently, GM Performance doesn't offer a suitable engine/trans package for this conversion. They have three different offerings...

Crate Engine

E-ROD

Crate Engine
GM does offer the LC9 (5.3L aluminum) truck engine as a crate option. Part number 19259918. (~$5,000) This can be used on this conversion. Available from Summit, Jegs...

Connect & Cruise
This package comes with a wiring harness, ECM, and optionally a transmission. Problem is GM Performance doesn't off the 6L80e transmission, yet. Therefore, any package engines won't have the correct ECM and wiring harness.

E-ROD
This package is the Connect & Cruise plus down pipes/cats and is California legal. Here again, since the 6L80e is not offered, it has the same problems as Connect & Cruise. Don't wast you money on this one. You will have to scap the down pipes/cat, exhaust manifolds, ECM and harness. Then you are left with the Crate Motor and no CA compliance.

So what are the options? You can purchase the LC9 Crate Motor from GM Performance, a 6L80e trans from the dealer (~$2800), and a wiring harness from the dealer (~$200), and an ECM from Amazon. This won't work in California as a donor VIN is required for an "engine change". I an not sure what other states require.

Will a Car Engine work?
Car engines can be used outside of California. However, the oil pan and pickup, water pump, and possibly the crank pulley will have to be changed. There are three pulley offsets. Close, medium, and long. The truck water pump is required here and uses the long pulley.

Hope this helps.
Let's please revisit the E-ROD solutions for a second. I understand that for the E-ROD ECU to control the transmission you have to buy the 4L85E transmission also from Chevy Performance. I also fully understand that the 4L85e transmission won't work with Nick's adapters. However, Marks4x4 in Australia does make a 4L80e to LT230 adapter. No it's not as good as Nicks. However if it also works for the 4L85e would all 3 of the e-rod engines(LC9, LS3 and even LSA) be options? Could I use the existing cats included in the kit(modified a little bit is OK)?

I definitely want an engine and transmission designed to work together AND I also like the idea of a crate motor rather than rebuilding a 65k to 100k motor out of another truck. The E-ROD idea is compelling especially if it could also be made CA compliant(a nice to have but not essential). I apologize for bringing back a post from page 18 when we are on page 50.

Donor 2009 35k miles Sierra 5.3 4WD 6 speed 6L80 ~$2400 US next to Defender 90. Guessing that more of these GM gen IV 4X4 6L80 combos will become available for even less over next few years?

Sorry for polluting this thread with D2 motor stuff. I'm looking for an LS solution for my Rover motor woes and I believe Nick has exactly what I need. I'll resume watching with interest.

PS. Here is the D2 forum if anyone is interested (where at least two guys are reinventing the wheel regarding chevy motor swaps). Discovery II - Land Rover Forums - Land Rover Enthusiast Forum

PPS. Sorry again and lets get back to replacing the ancient GM design with their latest and greatest.

PPPS. May your combustion gasses all find their way out the tallpipes and not into adjoining cylinders or coolant or the space between the block and the head where there really ought to be some head gasket... Amen!

Fwiw, CDN38 mentioned in a thread recently that his td5 flat highway mpg went up considerably. IIRC, something like low twenties to high twenties/low thirties with roamerdrive. So stock td5 might be around 25 hwy. I can't find it, but I found where he said he was doing 85 at 2600 rpm's with roamerdrive.

My original LT230 is a 20D so I believe it is a 1.6. I am going to find a Disco 1 with 1.2 ratio and put that in with the LS3 with 33" tires.

Merry Christmas to me and my Defender!

I got some nice shiny stuff from St. Nick!

Anyone have the jig they can ship me on my dime for the weld in motor mounts? Or measurements would work also. Thanks!
