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 compression ratio do the SC7299 pistons provide for the KA24E and KA24DE engines?
The SC7299 pistons provide a compression ratio of 8.0:1 for the KA24E and 9.0:1 for the KA24DE. This allows for a good balance of performance and reliability, especially when tuned appropriately.
What is the recommended bore clearance for the SC7299 pistons?
Bore clearance for the SC7299 pistons should be set according to the engine builder's specifications, typically around 0.0015” to 0.0025” for performance applications. Proper clearance is essential for thermal expansion and to prevent piston slap.
What type of wrist pins are included with the SC7299 pistons?
The SC7299 pistons come with standard wrist pins (21mm) included at no additional cost. Upgraded and ultra-duty pins are available for those looking for enhanced strength in high-performance applications.
Are the SC7299 pistons compatible with high lift camshafts?
Yes, the SC7299 pistons feature deep valve reliefs that accommodate high lift camshafts, making them suitable for performance builds that include upgraded camshaft profiles.
What machining processes are recommended for the SC7299 pistons?
It's recommended to check and possibly hone the cylinder bores to ensure proper fitment of the SC7299 pistons. Additionally, the pistons should be balanced with the full rotating assembly to achieve optimal performance and reliability.
