2.2 L Supercharger

Anyone know if there is a supercharger kit for the 2.2. I like super chargers better than turbos, less maintence, stuff to break(bearing). But any way I was looking for a s/c kit preferably from GMPP cause I was hoping i could then fit the GMPP stage Kits on there and still be under warranty. But as now know i know they have a 2.2L ecotec kit fot the Cav and Sunfire, any info would be great.

But then a turbo is too costly to maintain, plus if i get the S/c its still underwarranty, seeing as it's only a month old.

GM sells turbo kits already for the 2.2L with a warranty. I am not sure I am following you.

Turbo>Supercharged, cost effective and produces more gains. You will be spending more then $1,500 more to supercharge it. Waste of money IMO.

there is no kit out yet for cobalts from GM, or turbo kits really for that matter...

not sure if the stage kits would apply to the gm kit for the 2.2 either...

This is wrong. GM does not NOT sell any turbo kits, at all, for any model car.
They make Supercharger kits, and the one for the Cobalt is still not released.

You are wrong, they make kits already for the GXP Soltice 2.0L, they are just not released to the public until the middle of this year. that's why it's a good idea to wait. The motor will also be available at the middle of the end of the year as a crate motor. I was informed by the reps at the autoshow to look for this at this time. It will be part of the tuner page when they "Hopefully" update it towards the middle of the year.

Another thing is it's a Garrett Turbo (Or I have been told anyways). I didn't get trim numbers but I know it boosts between 16-18 PSI. It gets it's return feed from the oil pan.
here is a sneak peak at the motor manifold.

Enjoy



Stats sheet on Turbo Ecotec. yay!



Picture of the motor



I have guys that can adtest to this that went with me at the autoshow.

Good luck with your Hann kit but I believe the GM one will be better and more tuneable since they already have all the calibrations.

Also when I get home I will show you a motor shot and the turbo and I believe a part number for you as well.. all hinges if I took the picture of it. I know I did of the motor. I feel in another half a year this will be a popular motor swap.

Maybe what I am suggesting isn't cost effective but if you think of it this way. Rather then buying a S/C or a turbo for the 2.2L which is the same motor as the 2.0 but has less strengths why not go 2.0L Turbo and when you get the crate just swap the a/c, power streering, etc off the 2.2L to the 2.0 (they utilize the same materials) and drop her in. I can't imagine this being hard or costly...

Go S/C your wasting a couple grand to get a non-intercooled s/c installed that will heat like a motha *****.

Get a turbo kit from somewhere other then GM your hurting the chance that you can't tune it. Just trying to help him save some $$ if he wants the best possible power adders.

I won't suggest giving my motor to someone, especially after what happened to your 2.2L. That's rolling the dice. I know it's pay to play but you got screwed once already.

Here is some more information on the motor, why it kicks my mom right in the face.

Dual Scroll Turbo!



PONTIAC , Mich. — General Motors introduces the Ecotec 2.0-liter Turbo engine in the 2007 Pontiac Solstice GXP, making it GM's first direct injection offering in North America . Gasoline direct injection technology helps the Ecotec engine produce more power while maintaining the lower fuel consumption of a small displacement port-injected engine. It produces 260 horsepower (194 kW) and 260 lb.-ft. of torque (353 Nm),* making it GM's highest specific output engine ever, at 2.1 horsepower per cubic inch of displacement (130 hp / 97 kW per liter), and the most powerful production engine in the Ecotec family.

Variable valve timing and an intercooled, twin-scroll turbocharging system are used to optimize the Ecotec 2.0-liter Turbo engine's performance. It was developed with the global resources of GM Powertrain in the United States and Europe , drawing on expertise from the naturally aspirated Ecotec 2.2-liter direct injection engine used in some European applications and the 2.0-liter turbocharged engines already in production.

With direct injection, fuel is delivered directly to the combustion chamber to create a more complete burn of the air/fuel mixture. Less fuel is required to produce the equivalent horsepower, especially at normal cruising speeds, of a conventional port-injection combustion system.

"Direct injection technology works well with turbocharging and helps deliver a great balance of power and economy," said Ed Groff, assistant chief engineer, Ecotec 2.0-liter Turbo engine. "The Ecotec 2.0-liter Turbo produces the power expected of a V-6, but in a smaller, more efficient package — and the driving response is simply terrific."

A dual-scroll turbocharger with a lightweight turbine provides nearly instant power and an air-to-air intercooling system bolsters the turbo's performance by reducing inlet temperatures. Dual cam phasing complements the turbocharging system by optimizing valve timing at lower rpm for best turbo response and quick engine torque build-up time.

The Ecotec 2.0-liter Turbo uses a stronger, "Gen II" Ecotec engine block, which was developed with input from racing experience to support increased horsepower and torque. The cylinder block bulkheads — the areas where the main bearing caps are attached — and the bore walls are enlarged for strength. Other areas of the engine were enhanced to reinforce the structure and the water jacket is deeper for added cooling capacity and improved cylinder bore roundness. This architecture is shared with the 2.4-liter Ecotec engine that debuted in the Pontiac Solstice roadster.

Highlights of the Ecotec 2.0-liter Turbo engine include:

•Steel crankshaft
•Forged connecting rods
•Forged oil-galley pistons
•Jet-spray piston cooling
•9.2:1 compression ratio
•Aluminum cylinder head with sodium-filled exhaust valves
•High-pressure engine-driven fuel pump
•Variable pressure fuel rail
•Dual-scroll turbocharger

Components including the steel crankshaft, forged connecting rods and forged pistons are high-strength items that provide strength and enhance durability. Jet-spray oil cooling directed toward an oil-galley piston help reduce piston temperatures. The system delivers pressurized oil to continuously lubricate and cool the pistons, which reduces friction and noise and ensures durability for the engine's higher power levels. To enhance combustion, the piston tops feature a dish shape that deflects injected fuel toward the spark plugs.

To accommodate the direct injection system, the Ecotec 2.0-liter Turbo has a unique cylinder head and intake manifold. The cylinder head incorporates mounting locations for the fuel injectors — which are typically mounted in the intake ports or intake manifold on port injection engines. A high-pressure fuel pump delivers fuel to a variable-pressure fuel rail. Fuel enters the combustion chamber through precision multi-hole fuel injectors. The fuel pump, fuel rail pressure, fuel injection timing, and injection duration are controlled by the engine control module. In this way, fuel is metered and delivered in a finely atomized spray.

Apart from the mounting positions of the fuel injectors, the cylinder head has conventional port and combustion chamber designs, although both are optimized for direct injection and high boost pressures. The sodium-filled exhaust valves and stainless steel exhaust manifold are durable components designed to stand up to the high-performance capability of the engine.

The unique cylinder head, fuel system, pistons, intake manifold, and the dual-scroll turbocharger are the only major components that differentiate the 2.0-liter Turbo from other members of the Ecotec engine family. Mobil 1 synthetic engine oil is installed at the factory. Synthetic oil was selected for its friction-reducing capabilities and high-temperature performance.

How direct injection works

Gasoline direct injection differs from the fuel delivery process of a conventional engine by delivering fuel directly into the combustion chamber, where it is mixed with air drawn in to the chamber. The combustion process of conventional fuel injected engines uses air and fuel that are mixed in the intake port or intake manifold prior to being introduced into the combustion chamber. Direct injection is a continuation of the evolutionary process of moving the fuel introduction point closer to the combustion location to improve control.

With the Ecotec 2.0-liter Turbo, fuel is introduced directly to the combustion chamber during the intake stroke. As the piston approaches top-dead center, the mixture is ignited by the spark plug, giving the name spark ignition direct injection (SIDI). The fuel injectors are located beneath the intake ports. SIDI allows the mixture to be "leaner" — less fuel, more air — at full power. SIDI also permits a slightly higher compression ratio than if the fuel were delivered with conventional fuel injection. The result is better fuel consumption at part and full throttle. The engine uses conventional spark plugs similar to other Ecotec engines.

A high-pressure, returnless fuel system is employed. It features a high-strength stainless steel fuel line that feeds a variable-pressure fuel rail. Direct injection requires higher fuel pressure than conventional fuel injected engines and an engine-driven high-pressure fuel pump is used to supply up to 1,276 psi (150 bar) of pressure. The system regulates lower fuel pressure at idle — approximately 752 psi (50 bar) and higher pressure at wide-open throttle. The cam-driven high-pressure pumps works in conjunction with a conventional fuel tank-mounted supply pump.

Direct injection's precise fuel delivery enables more complete combustion to help reduce emissions, particularly on cold starts — the time when most engine emissions are typically created. Also, direct injection permits higher a compression ratio in the engine which is a positive influence on fuel economy. At certain power levels, the boosted SIDI engine can provide significant fuel economy benefits to the vehicle compared to a larger displacement naturally aspirated engine.

Turbocharging system

A unique, dual-scroll turbocharger is partnered with an air-to-air intercooling system to provide up to approximately 20 psi (1.25 bar) of power-enhancing boost. The dual-scroll turbocharger delivers nearly instant response, as dual exhaust passages from the engine to the turbine housing guide exhaust gas to the turbine. This reduces lag time, or spool-up, at low rpm.

"There is virtually no lag with this system," said Groff. "Throttle response is immediate. The engine acts like a larger displacement engine."

The turbocharger is matched to the engine's displacement and performance objectives. It is supported by the air-to-air intercooling system, which uses fresh air drawn through a heat exchanger to reduce the temperature of the warmer compressed air forced through the intake system by the turbocharger. Inlet temperature is reduced by approximately 212 degrees (100 degrees C), enhancing performance because cooler air is denser and promotes optimal combustion.

Dual cam phasing

The camshafts of the Ecotec 2.0-liter Turbo engine have phasers that support the continuously variable intake and exhaust valve timing. They also have cam position sensors, so that the engine control module can accurately control valve timing. The crankshaft and camshaft position sensors are digital. A new engine controller, specific to the engine, is used to sense and control the engine's performance parameters.

Variable intake and exhaust timing works synergistically with both the gasoline direct injection and turbocharging systems. The variable engine timing enabled by cam phasing allows the combustion process to be optimized. Also, valve "overlap" at low rpm can be adjusted by the controller to increase the response of the turbocharger, providing a more immediate feeling of power.

Ecotec family traits

The Ecotec 2.0-liter Turbo is built on a global platform that was designed at the outset for a range of performance and combustion capabilities. The Gen II block supports the high-performance demands of the engine, but it is merely a strengthened version of the original Ecotec architecture. The oil pump, for example, is the same as used in all other Ecotec engines. It was originally designed to support high-performance applications of future engines.

"The 2.0-liter Turbo is the pinnacle of Ecotec performance to date, with additional growth planned. The groundwork for its capabilities was layed on the drawing table at the very beginning of the Ecotec's development,' said Groff. "Prior work and a far-thinking engine design continue to help GM respond to market demands around the globe more quickly and with greater accuracy."

This new Ecotec family member also has traits that have helped forge a reputation for durability and sophistication:

•Dual overhead camshafts (DOHC) and four valves per cylinder
•Twin counter-rotating balance shafts for operational smoothness
•Electronic throttle control
•Low-friction, roller-finger follower valvetrain with hydraulic lash adjusters
•Low-maintenance chain-drive for the camshafts
•58X crankshaft positioning
•Direct-mount accessories, which reduce or eliminate traditional sources of noise and vibration
•Full-circle transmission mount to reduce noise and vibration
•GM Oil Life System, which can reduce the frequency for oil changes
•Innovative cast-in oil filter housing, which eliminates the need to crawl under the vehicle to perform oil changes and eliminates throwaway oil filter cans that retain used oil

As with other engines in the Ecotec family, the 2.0-liter Turbo engine also has premium features designed to ensure smooth and quiet operation, including a polymer coating and skirt design for the pistons that reduces noise during cold starts. An automatic hydraulic tensioner also is used to maintain optimal tension on the timing chain, which reduces noise and vibration.

*SAE certification pending. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005. This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using the procedure and expects to use it for all newly rated engines in the future.

don't you just love it when something badass gets released after you've already purchased your car.

although that engine will be coming out the likelyness of it being swapped into a Cobalt is probably going to be small...crate motors are not cheap and I doubt anyone would wanna be the test boy for the swap. Also gotta wire in that VVT!

On paper though that 2.0L Turbocharged engine sounds really good, should've put it in the SS/SC

Actually, I'm not wrong. GM doesn't sell turbo kits. That's what I said, and that is true. You can not buy a turbo kit for any GM motor from GM. Read my post again.

I am well aware that the 07 Solstice will have a factory installed turbo ecotec. But that isn't a kit. For the Cobalts with L61 engines, you will not, nor will you probably ever, be able to buy a GM turbo kit for it. They are making a supercharger kit for it. That is the only forced induction option that GM will probably offer.

However, nice post on the Solstice engine info. Looking at, it appears to have a completely different cylinder head to accomodate the direct injection, but the block is basically the same.

By the way, does anybody know what that extra pump on the lower left side of the accessory drive is? It has a drive belt all its own. It could be a power steering pump, but that would mean no more electric power steering.

anyone who does it will have a bad ass SS. personally, I won't put it past even myself to buy the motor and do the swap.

You are right, no turbo kits from GM! Not yet, since they making turbo vehicles in the near future, I would think kits from GM will be available in like 3 YEARS!!

It just occured to me that we never answered this persons question. And me being a moderator and supposed to keep things on topic, shame on me.

Yes sir, there is a supercharger kit (not a turbo) available for our cars. RSM has one. Look here:

One thing to note is that even if GM were to make the parts available for you to buy off the Turbo Solstice, they are probably going to be very expensive.

Eg. The Mazdaspeed.

If you wanted to buy all the parts from Mazda that make a Protege into a Mazdaspeed, it would cost to about 4 times more than just getting an aftermarket kit. If you think that they will honor your warranty that is a joke as well.

Mazda sells the turbo for the Mazdaspeed for just over $2200.00. You can get a new off the shelf turbo direct from garrett for just over $1000.00
