Engine

The DDMWorks Coil Cover will fit both the 2.4 (LE5) and the turbo 2.0 (LNF) motors. This Coil Cover comes with stainless steel hardware to attach directly to the Cam/Valve cover.

The DDMworks center feed fuel rail is designed for high horsepower Ecotec motors. The center feed on the rail provides more consistent fuel pressure across all of the injectors. This is important when pushing the stock motor to higher horsepower. This billet aluminum fuel rail is a direct replacement for the stock fuel rail, and with 2 removable end caps that can be used for fuel pressure gauges, or extra fuel for nitrous kits.

The skirt shape (barrel/cam) is one of the most functional areas on the piston, and provides stability and smooth operation in the cylinder bore. Stability is important for proper ring seal, reduced friction, and quiet operation. Each skirt shape is designed for a specific running clearance, based on coefficient of thermal expansion of the piston alloy. Some forging alloys expand more than casting alloys, but each Wiseco piston is designed with the proper installed clearance to produce the most power, least wear, and best seal at running temperature, for each application. Comparing installed clearances on cast vs forged parts is not indicative of the running clearance at temperature. Wiseco engineers have a strong background in all forms of racing applications, and produce the best shapes and designs in the industry.

Bore size notes - Stock bores can wear slightly over time which can result in too much piston to cylinder wall clearance. At our shop we prefer to use .5mm larger pistons which require a slight overbore on the sleeves but bore the cylinders to match the pistons exactly and keep the piston to wall clearance in the specified range.

Compression ratio notes - Lower compression rates are available through custom order, however lower compression ratios are not needed for most builds.

Super strong way to hold your engine together for high horsepwoer engines

Built Solstice / Sky 2.4L Engine by DDMWorks

Our high temp reinforced silicone coolant hose kit is direct fit for 2.0L 2007+ Pontiac Solstice GXP, Saturn Sky Redline,Opel GT and also fits 2.4L 2006+ Pontiac Solstice, Saturn Sky (these models will not use the Turbo waterline return).

This LE5/LNF coil pack cover is made of rust resistant aluminium and is available in multiple powder coat colors!

Oxygen Sensor Extender

No cores, no mess, we only offer brand new valve covers direct from dealer that are carefully prepared and powdercoated in your choice of color, this even includes a new valve cover gasket! We have brand new valve cover cores come in and then carefully prepare each one for the powder coating process.

The 2.4 Mach with resonator exhaust kit was developed for those with the 2.4 Solstice that wanted the look of true dual exhaust. This is a no drone but full bodied exhaust note. This is one of our louder exhaust kits for the 2.4 Solstice, it’s the same as our GXP-Mach kit except we incorporated our Quantum resonator in the front pipe. This gives the 2.4 some needed backpressure and sound reduction. For the look and sound of true duals this is your kit!

• Includes all necessary hardware for installation.
• A rear valence change must be done to provide outlets for the left and right exhaust tips. The rear valence is not included in this kit as many people get the GXP valence from their dealer. You can order a painted valence from Norm’s Fiberglass www.normsfiberglass.com (574)255-7843. Prices range from $350.00 to $500.00 USD depending on valence type and paint colour.
• The “Mach w/ res” exhaust kit offers the looks of true duals for your 2.4 Kappa. It is louder than the SQR-2 or SINGLE. It’s recommended for those that like a full bodied louder but no droane, exhaust note.

2.4 Mach with Resonator Kit

Front Pipe:
• 3” mandrel bent polished stainless steel with our quantum resonator built in to sweeten the sound.
• Laser cut stainless steel flange.
• Extra hanger included for support.
• Heavy duty double braided flex pipe is used.
• A very precise hand made flair is on the front pipe to alleviate having to reduce the pipe to 2 ½”.

Mid Section:
• Dual 2 ½” pipes are used in this mid section.
• This does not restrict the flow as dual 2 ½” pipes flow more than a single 3”.

Rear Section:
• We decided to go with the more difficult design of a dual in dual out muffler.
• This muffler is a heavily packed with ceramic fiber and stainless steel wool, and a true X design muffler. Made from stainless steel.
• The tails flow into a beautifully crafted beveled 4” angle cut full bodied stainless steel exhaust tips manufactured by Solo Performance.
