This is a brand new set of GSC Power-Division Stage1 Turbo Cams for Mitsubishi 4G63 2.0L Engines found commonly in the Mitsubishi Eclipse, Galant VR4, Plymouth Laser, Eagle Talon, and other platforms. Stage 1 - This cam is perfect for mildly modded engines that have bolt-ons (intake, exhaust, etc) but retaining stock, or close to stock sized turbo. This cam would be perfect for someone that is looking to pick up more power per pound of boost. This cam behaves well on the street, and does not sacrifice any drivablility. GSC Cams are known for making power at a reasonable price. If you Google "GSC Cams" you would be hard-pressed to find anyone saying something bad about them. We use them in our Race Heads and have never had a problem. If you have any questions about cams or valvetrain please do not hesitate to contact us. Sales@RealStreetPerformance.com
