Another video coming soon. We finished hooking up the exhaust. Cuts were needed right in front of the cats, but from the cats back it is the same as factory. Sounds basically identical to stock.

Road test video is up:
In this video, the exhaust is fully welded up with cast manifolds (unlike the first video, where there was no hood and open headers). It's as quiet as stock cruising down the highway. Most of the noise you hear when idling around is the viscous fan. The untrained observer would think its unmodified.
Probably the best part about this whole conversion is that it gives you options: you can make it as loud or quiet as you want, as close to factory as possible or an absolutely outrageous machine.
We're getting more organized. More updates incoming.

We've been working on an LS conversion for the Discovery 2 for the last year. All adapters were made in house and utilize the factory transmission and transfer case. We are using a stock GM LS 5.3L Vortec engine. This engine came straight from a junkyard with 120,000 miles and very few modifications. We're using a GM engine computer to run the LS, while the Bosch runs the transmission and everything else. Everything has been working very well so far. Going to do some more testing in the coming weeks.

Some more updates. Things are moving right along. Still running great. It seemed to average right around 18 mpg on last highway trip on regular gas. It definitely seems like all the parts are ‘settling in’.
As things are getting further along, I’ve had some questions about a parts list. Here is a general list of what you will likely need in addition to the kit and approximate pricing. This is just for guidance purposes and subject to change. I’ll be making a detailed list with more current prices. Much of this depends on what comes with your engine and what kind of deal you can get from the junkyard. An LR4 4.8L engine can be found for very cheap (<$500 if you shop around, Craigslist).
Engine Kit $1600
LS engine (Gen 3, LR4, LM7, LM4, L33; 4.8/5.3L) $700
LS wiring harness (non-emissions) $550
LS engine computer (ECU) flashed to our specifications $200
Low profile oil pan $200
Exhaust manifolds or headers $200+
Heater hoses and assorted coolant hoses $100
O2 Sensors (front) $60
Spark Plugs $55
Intake Piping $100
Various Other Sensors $200
Miscellaneous hoses, oil, coolant $200
Total $4165+
Emissions harness +$250
Emissions sensors +$200
Harness rewire option +$350

The AFM / Displacement on Demand was a feature of the Gen IV LS engines. This is a Gen III engine. AFM could probably be implemented on a Gen IV engine with this swap. Gen IV/V would add a lot of complexity though and makes the cost go up substantially, so that's why were focusing on Gen III. We're looking at Gen IV/V as down-the-road options.
