GSC Power-Division Billet R2 cams for the VVTI Toyota Supra 2JZ-GTE. The R2 cams are designed for those running large single turbos, larger than 76mm.

These cams will not have bottom end losses over our S2 cams; nothing but gains will be seen and will promote great peak power gains. Designed for a rev range of 4500-9000 RPMs.

These cams require an upgraded valve spring set such as our Conical Spring kits (GSC5064 or GSC5066) along with shimless buckets/tappets and head clearancing for lift.

Valve spring upgrade is required when using these camshafts.

Camshafts

GSC Power-Division camshafts are engineered to maximize airflow, power production, and usable RPM while maintaining the valvetrain stability required for real-world performance. Unlike generic “one-size-fits-all” profiles, GSC camshafts are developed using application-specific analysis that considers cylinder head flow characteristics, valvetrain geometry, rocker motion, intended powerband, fuel type, and engine configuration.

Manufactured from forged barstock in house with precision-ground lobe profiles, GSC cams are trusted by engine builders, tuners, racers, and enthusiasts around the world — from street cars to record-setting drag programs. Whether the goal is improved response, broader power delivery, or extreme horsepower capability, GSC camshafts are built around one principle: maximizing performance without compromising valvetrain control.

Frequently Asked Questions

What makes GSC Power-Division camshafts different?

GSC Power-Division camshafts are engineered specifically for high-performance applications using proprietary lobe designs, premium billet materials, and advanced manufacturing processes. Every camshaft profile is developed to maximize airflow, power, durability, and valvetrain stability for its intended application.

How do I choose the correct camshaft for my application?

The best camshaft depends on your engine configuration, turbocharger size, intended RPM range, fuel type, cylinder head setup, and horsepower goals. If you’re unsure, contact our technical support team for recommendations.

Will aftermarket camshafts increase horsepower?

Yes. Properly matched camshafts can significantly improve airflow, power, torque, and RPM capability. Actual gains depend on the overall engine combination.

Do I need valve springs with aftermarket camshafts?

In many cases, yes. More aggressive camshaft profiles require upgraded valve springs to maintain valve control at higher RPMs and boost levels. Product pages will indicate whether upgraded springs are required.

Can I use GSC camshafts with OEM valve springs?

Some Stage 1 camshafts are compatible with OEM springs under certain conditions. Always verify spring requirements listed on the product page before installation.

Do I need a tune after installing camshafts?

Most performance camshaft installations benefit from ECU recalibration. A proper tune helps maximize power, drivability, and reliability.

Are your camshafts billet?

Yes. GSC performance camshafts are manufactured from premium forged billet cores for maximum strength and durability.

What is BLACK ISE?

BLACK ISE is GSC’s advanced surface treatment process designed to reduce friction and enhance durability in high-performance valvetrain environments.

GENERAL F.A.Q

Where are GSC products manufactured?

Many GSC products, including our camshafts, are designed, machined, and finished in-house at our facility in South Carolina, USA. We maintain strict quality control throughout the manufacturing process.

How long has GSC been in business?

GSC Power-Division has been serving the performance automotive industry for over 20 years, supplying racers, engine builders, tuners, and enthusiasts worldwide.

Do you sell directly to consumers?

Yes. We sell directly through our website and also through an extensive network of authorized dealers and distributors worldwide.

Does GSC cover engine damage?

GSC’s warranty covers defects in the product itself. Consequential damages, including engine damage, labor, towing, or vehicle downtime, are not covered.

Will racing void my warranty?

Products used in racing or competition environments are subject to conditions outlined in our warranty policy. Performance applications inherently involve risks beyond normal operating conditions.
