When you start to make more power with the stock engine you run the risk of having an engine failure. The Stock LE5 engine found in the 2006-2010 Pontiac Solstice and 2007-2010 Saturn Sky can be safely ran up to 350hp at the wheels, although we recommend looking at building the engine when power gets over 300hp at the wheels for reliability. If you are looking at exceeding stock power or just want the peace of mind knowing that your engine can take the abuse you are going to give it, our DDMWorks built engines are the best option. We have designed our DDMWorks built long blocks for performance, strength and reliability in your Solstice or Sky and have been building the 2.4L since 2007. After building many of these engines we have done the research to build engines with the best parts to give you a engine that you can install and expect a long life from, along with high performance.
We start by removing the cylinder head and inspecting it for any damage, then the head is completely dis-assembled by removing all valves, valve springs and retainers. The 3 mating surfaces are machined for a nice smooth surface, the cylinder head is thoroughly cleaned, pressure tested and then re-assembled with new valve guide seals.
All of our engines start with either your stock block or a 2.4L LE5 core and are then completely disassembled and fully cleaned. The deck gets fully machined to give a smooth mating surface to the head, the rotating assembly is balanced and the engine is then re-assembled with the following new parts -
- Full set of GM Main Bearings
- Full set of GM Rod Bearings
- GM 2.0L LNF Head Gasket
- GM Rear Main Seal
- GM Timing Plate Cover Gasket
- Qty. 20 GM Main Bolts
- Qty. 10 GM Girdle Bolts
- ARP Head Studs
- Forged Rods (option of Molnar or Carillo)
- Wiseco Pistons with Slick side coating, wrist pins, rings, locks @ 88.5mm bore
- GM Timing Chain
- GM Timing Chain Tensioner
- GM Upper Timing Chain Guide
- GM Slack Side Timing Chain Guide
- GM Tension Side Timing Chain Guide
- GM Valve Cover Gasket
- GM Water Pump
With this build you end up with an engine that can take the power you want to put down with your Solstice or Sky in a package that comes to you ready to install in your ride.
