I believe it's the LTG thats in the ATS...

 

It's an LHU i think. It's supposed to be a stronger block also, gen4 i think..

 

oh well ok, but i got one to check out outside of a car and i was wondering if everything is in the same spot as the LNF so i can get a general idea of placement of the stuff...

Actually it's a Ltg , the lhu was in the 2012 regal.

Here is some good info on what changed



The current LHU engine has these features:

DI ( direct injection )
Dual-scroll turbocharger
Dual CVCP (continuously variable cam phasing)
Sodium-filled Iconel exhaust valves
Aluminum pistons with jet-spray cooling
Forged Powdered Metal (PM) connecting rods
Forged Steel crankshaft
Semi-permanent-mold 356 Al cylinder head
Variable pressure fuel rail ( 50-150 bar )
Stronger block bulkhead and deeper water jacket
Coil-on-plug ignition
Direct injection high-pressure multi hole injectors
58x engine position sensing
Stainless steel fuel system components
Dual converter system
Cam driven high pressure fuel pump
Mechanical brake vacuum pump

and the new LTG engine features:

Among the 2.0T engine’s highlights: a direct-injection twin-cam, four-valve-per-cylinder engine with continuously variable valve timing; twin-scroll turbocharger with air-to-air intercooler; forged-steel crankshaft with modular balance shaft system; and a two-stage variable-displacement oil pump with jet-spray piston cooling.

None of which spring forth as new compared to the current design.* The current applications do have an air to air intercooler.

Looking at the two engine images above, there are some clear differences in configurations.* However, I wonder if the real secret of the new LTG 2L Turbo tune is that it can make 260 hp on regular unleaded instead of premium?* The current LHU engine is “premium recommended, but not required; L85 capable”.* Only needing regular unleaded would fit well with Cadillac’s tuning for the 3.6L to run on regular unleaded, and makes a nice bonus for the ATS.

 

LHU







LTG

 

LDK is a non-E85 certified version of the LHU, which is basically the LNF with a couple slight adjustments.

LTG is a true gen 2 motor, totally different than the LNF/LHU/LDK stuff. Trifecta has all 3 engines in their current fleet and the LTG makes the most power by far. 412HP as calculated by the ECM on E85.

 

If you look at the 2 engine pics, you'll see a MAJOR change.

The intake is where the the exhaust was...
And the exhaust is where the intake was...

The balance shafts are in the pan now in the LDG

 

While there are still many similarities with the new turbo Ecotec that's being used in the ATS, GM stated they revised a great majority of the internals and made a lot of small changes for improved efficiency and durability. They're essentially calling it an all new engine design.
