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 compression height for the S1303 pistons?
The S1303 pistons have a compression height of 1.250 inches. Ensure this is compatible with your engine's deck height and desired compression ratio.
Can the S1303 pistons be used with a 3.750 stroke crankshaft?
Yes, the S1303 pistons can be used with a 3.750 stroke crankshaft, provided you maintain the correct deck clearance and ensure proper fitment with your specific engine setup.
What is the weight of the S1303 pistons, and how does it affect performance?
The S1303 pistons weigh 444 grams. A lighter piston can improve engine response and RPM potential, but ensure that your engine's rotating assembly is balanced accordingly.
Are the S1303 pistons suitable for use with angle milled heads?
Yes, the S1303 pistons are designed to be suitable for use with angle milled heads, but verify that your overall compression ratio remains within acceptable limits for your application.
What type of wrist pins are included with the S1303 pistons?
The S1303 pistons come with .927 x 2.750 inch wrist pins, and pin fitting is included at no additional cost, ensuring a precise fit for your application.
