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 S2030 pistons?
For the S2030 pistons, a typical bore clearance of 0.0020" to 0.0025" is recommended. However, final clearance should be determined by the engine builder based on specific application and tolerances.
What type of ring pack is included with the S2030 pistons?
The S2030 pistons come with a lightweight metric ring pack consisting of 1.5mm x 1.5mm x 4.0mm rings. Ensure proper installation and gap settings as per your engine's requirements.
Do the S2030 pistons require any special machining?
Yes, the S2030 pistons may require specific machining for optimal fitment, including honing of the bore and checking for correct ring groove depth. Always consult with your engine builder for precise machining needs.
What is the piston weight of the S2030 and how does it affect performance?
The S2030 pistons weigh 367 grams. A lightweight piston can improve engine response and reduce reciprocating mass, but ensure that the overall engine balance is maintained during assembly.
Are gas ports included in the design of the S2030 pistons?
Yes, the S2030 pistons feature gas ports which help improve ring seal and reduce blow-by. Proper installation and tuning are essential to maximise their benefits.
