World's First - '71 Series IIa w/ Chevy LTG & T56 6-Speed

We built this Series IIa with a 2017 Chevrolet LTG 2.0T engine mated to a Tremec T-56 6-speed manual. Truck drives great and the swap only required modifications to the center transmission tunnel. We even used the stock engine mounting locations.

Just wanted to post this up here for now to start our build thread. It's about time the Series trucks got some appropriate power upgrade options!

We did all of the R&D in house so we will be able to offer a kit for the DIY'ers out there to install in their garage if they want. From the motor mounts, to the bell housing to custom adapters and spacers. Any questions just shoot me a note.

2017 Chevrolet LTG (Gen VI) 2.0T
Tremec T-56 6- Speed Manual
Forbyn Bros T-Case
Salisbury Military Axles
4.7 Rear Gears w/ Detroit TrueTrac LSD
4 Wheel Disc Brake Kit

RestoMod Air Conditioning Kit
Custom Gauges

Limestone Exterior w/ Matte Clear and natural patina

Thats a mighty gearbox for the engine. Its not going to break in a hurry. Given that the Defender (and Discovery) both had 2.0 gasser engines in limited numbers, its not a bad idea.

Very nice!

Disregard previous comment - realize it's a 2.0 engine!

Haha - I have been looking for the weight of it for the last 10 minutes but gave up. I'm going to guess its under 350 lbs.

Impressive power output but price wise I bet you are in GM LS category for a Defender install.

It's not the cheapest engine swap option out there but the 4 cyl is a much better fit than the LS series engines. We trimmed the passenger side motor mount a bit but other than that it dropped right in to the factory location.

You can get the LTG engine + controller from a Chevy performance dealer for around $10k. Not terrible for 300 HP, few hundred pounds of weight savings and a factory 50k mile warranty.

I agree - very nice option for a Series with the smaller engine compartment. The fact that the factory engine mounts are retained is a big plus IMO.

Come to think of it, it might be a nice option for a Defender if you could keep the engine mounts and get a LR gearbox to bolt up. I'm guessing it's similar in size to a 2.5/200Tdi? 300HP would blow up a LT77 but maybe a de-tuned program to 250? Just throwing "what ifs" around.

Subscribed...Very cool Scott. Look forward to seeing more.

Don't mean to clutter your thread but I don't understand why GM would promote an engine as small and light weight and not publish the weight and dimensions? never encountered that before.

There isn't a ton of info on this engine anywhere. This was the first year they offered this package for sale and even the GM Performance group was less than familiar with the setup.

Not sure why they are so secretive about details but this engine is an absolute beast. No way it's ONLY making 272HP. We took the truck on it's first highway run yesterday and it just does not let up.
