What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.
What is the recommended application for the Toyota 4AGE 16V Valve Spring Kit?
The Toyota 4AGE 16V Valve Spring Kit is designed for both street and track applications. It is ideal for engines that operate under high RPMs, providing enhanced durability and performance.
What are the key specifications of the valve springs in this kit?

Do I need to modify my cylinder head to install these valve springs?
Typically, no major modifications are required for installation, but it is essential to ensure that the cylinder head is in good condition and that the springs fit properly within the existing setup. Always check for adequate clearance and coil bind.
Can I use these valve springs with aftermarket camshafts?
Yes, the Toyota 4AGE 16V Valve Spring Kit is compatible with aftermarket camshafts designed for the 4AGE engine. However, ensure that the camshaft specifications align with the spring rates to avoid valve float at high RPMs.
What maintenance should I perform after installing these valve springs?
After installation, it's advisable to check the valve spring heights and retainer clearances periodically, especially after initial break-in. Regularly inspect for wear and ensure that the springs maintain their performance characteristics over time.
