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 bore clearance for the CP Pistons SC7654 in a Toyota 4AGE?
The recommended bore clearance for the CP Pistons SC7654 is typically between 0.0015" to 0.0025". However, this can vary based on the specific application and the engine builder's preferences. Always consult with your engine builder for the best clearance based on your setup.
What compression ratio can I expect with the CP Pistons SC7654 in my 4AGE?

Do I need to modify my engine for these pistons to fit?
While the CP Pistons SC7654 are designed to fit the Toyota 4AGE, some engine builders may need to perform minor modifications such as honing the bore or adjusting the ring gaps to ensure optimal performance and fitment. Always check with your engine builder for specific requirements.
What type of rings are compatible with the CP Pistons SC7654?
