GSC P-D Toyota 2JZ-GTE VVTI R2 Methonal Cams 278/294 Billet (Upgraded Springs/Lobe Clearance Req)

If you're building a high-performance Toyota 2JZ-GTE VVTI engine, especially one set up for methanol injection, these GSC Power Division R2 camshafts are a serious consideration. These aren't your everyday cams; they're designed for engines pushing the limits, aiming for maximum power output when running on methanol fuel. The 278-degree intake and 294-degree exhaust duration are substantial, meaning these cams will significantly alter the engine's breathing characteristics to support higher RPMs and increased airflow, which is crucial for making big power with methanol.

Crafted from billet material, these camshafts are built to handle the stresses of a high-output engine. The R2 profile is specifically tuned for methanol, taking advantage of its properties to achieve impressive power gains. Because these cams have a more aggressive profile than stock, they require more than just a simple swap. You'll need to ensure you have upgraded valve springs that can handle the increased lift and faster valve action, and you'll also need to check and potentially modify the lobe clearance to ensure proper operation and prevent interference within the cylinder head. This is a component for a dedicated performance build where every detail matters for achieving peak performance.

When installing these camshafts, remember that they are designed for maximum performance and will change the engine's idle characteristics and overall driving feel. It's essential to consult with your engine builder or a performance tuning specialist to ensure your engine management system is properly calibrated to take full advantage of this camshaft profile, especially when running methanol. This is a component that demands careful setup and tuning to unlock its full potential.
