“Kappa” refers to General Motors’ subcompact rear-wheel drive automobile platform for roadster applications.
This automotive architecture debuted in the 2006 Pontiac Solstice and 2007 Saturn Sky, and the Opel GT, these ended production in 2009, although some 200 cars were built in 2010.
It has been stated by GM that the platform has only been designed to accommodate a single engine: the Ecotec, furthermore, the engineers have also stated that this platform was only designed to be left-hand drive. However, there are aftermarket tuners that have already accomplished non-trivial engine transplants in Solstices.
Since the Solstice, GM has designed another roadster that looks substantially different, but shares the same underlying Kappa platform: the Saturn Sky.

Saturn Sky was styled after the pattern of the Vauxhall VX Lightning design.

There is a European version built on the same platform, essentially a turbo-engined Sky with Opel badging, under the name Opel GT.

The Kappa architecture uses major components from nearly every GM division and modern platform:

  •  rear axle and differential are from the Sigma-based Cadillac CTS
  •  Solstice’s interior storage bin is from the Y-body Cadillac XLR
  •  passenger-side airbag, steering column, and exterior and interior door handles are from the Delta-based Chevrolet Cobalt, Pontiac G5
  • Solstice’s backup lights are from the GMT360 GMC Envoy
  • Heating, ventilating, and air conditioning modules are from the Hummer H3
  • Solstice’s front fog lamp assembly is from the W-body Pontiac Grand Prix
  • Solstice’s steering wheel is from the Delta-based Pontiac G5
  • 2.4 L Ecotec engine is shared with the Delta-based Saturn Ion, Pontiac G6, Chevrolet Cobalt, Pontiac G5, and Chevrolet HHR
  • five-speed manual transmission is from the Hummer H3, GMC Canyon, and Chevrolet Colorado
  • Thfive-speed automatic is from the Cadillac CTS, STS, and SRX

2.0 LNF: Technical stuff:

Ecotec LNF in a Pontiac Solstice
A turbocharged direct injected (redubbed Spark Ignition Direct Injection) Ecotec was introduced in the 2007 Pontiac Solstice GXP and Saturn Sky Red Line. The engine is mounted longitudinally. Displacement is 2.0 L—1,998 cc (121.9 cu in)—with a square 86 millimetres (3.4 in) bore and stroke. Compression is 9.2:1 and maximum boost is 1.4 bar (20.0 psi), delivering 260 hp (190 kW) at 5300 rpm and 260 ft·lb (350 N·m) of torque from 2500 to 5250 rpm, engines redline is at 6300 rpm and premium fuel is recommended.

Sodium filled exhaust valves were based on technology developed for the Corvette V8 powertrains. The sodium fuses and becomes a liquid at idle, which improves conductivity and draws heat away from the valve face and valve guide towards the stem to be cooled by the engine oil circulating in this area.

Camshaft-driven direct injection systems pressurize the fuel to 31 bar (450 psi) at idle, and up to 155 bar (2,250 psi) at wide-open throttle. The “Gen II” block is similar to the 2.4 L and also features VVT technology.

The Gen II block was developed using data from racing programs and computer simulations, bore walls and bulkheads were strengthened with a weight increase of 1 kg (2.5 pounds).  Coolant jackets were expanded to improve heat transfer, resulting in a coolant capacity increase of 0.5 liters.

In December 2008, GM released a Turbo Upgrade Kit for the LNF engine which increases horsepower to 290 hp (220 kW) and torque to up to 340 ft·lb (460 N·m), depending on the model. The kit retailed for $650 and included remapped engine calibration and upgraded MAP sensors. [5]
This was the final Stage 2 performance tune for the Ecotec family, to date, since the demise of the GM Performance Division, performance tunes like this have been relegated to the aftermarket sector. This despite newer engines being more durable and tuned to lower horsepower levels in numerous sport-car applications.

Unique LNF features [6] include:

*a twin-scroll turbocharger
*Cam-driven high-pressure gasoline direct injection fuel system
*Dual camshaft continuously variable valve timing
*Sodium-filled stainless steel Inconel exhaust valves
*Low friction cast aluminum pistons with oil squirters
*Forged steel crankshaft
*Forged steel connecting rods
*Cast stainless steel exhaust manifold
