GSC P-D Toyota 2JZ-GTE VVTI R1 Cams 269/269 Billet (Upgraded Springs/Lobe Clearance Req)

These GSC Power Division R1 camshafts are ground from solid billet steel, a strong foundation for improved performance in your Toyota 2JZ-GTE VVTI engine. With a duration of 269 degrees on both the intake and exhaust lobes, these cams are designed to increase airflow into and out of the cylinders, especially at higher RPMs. This means your engine can breathe more freely when it's working hardest, potentially leading to a noticeable increase in power and torque. Because these cams have a more aggressive profile than stock, you'll need to ensure you have upgraded valve springs to handle the increased lift and faster closing speeds. You'll also need to check and potentially modify the lobe clearance to prevent interference with other engine components.

The R1 grind is a popular choice for enthusiasts looking for a significant performance bump without going to an extreme setup. It strikes a good balance between streetability and track performance. The billet construction means these cams are well-built and can withstand the stresses of a performance engine. When installing these, pay close attention to the manufacturer's recommendations regarding valve spring pressure and any necessary machining for lobe clearance. This careful attention to detail during installation is key to unlocking the full potential of these camshafts and ensuring reliable operation.

It's important to note that these camshafts are not CARB approved and cannot be shipped to California. Always consult the GSC Power Division installation guide for the most accurate information on required supporting modifications and procedures. Proper tuning after installation will also be crucial to take full advantage of the improved airflow these cams offer.
