STD bore size pistons are not recommended in a used bore for any performance engine unless the bores have done minimal work with minimal wear and the correct piston to bore clearance can be adhered to.
All piston manufacturers have a specific piston to bore clearance that they recommend. If STD bore pistons are requested and there is a piston to bore clearance issue we will not exchange or refund, due to the reasons given above.

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 are the recommended bore sizes for CP Pistons in CA18DET engines?
CP Pistons for CA18DET engines are available in several bore sizes: 83mm (STD), 83.5mm (+0.5mm), 84mm (+1mm), and 84.5mm (+1.5mm). Each size is offered with compression ratios of 8.5:1 or 9.0:1.
Can I use STD bore size pistons in a worn engine block?
STD bore size pistons are not recommended for use in a worn engine block. They should only be used if the bores have minimal wear and the correct piston to bore clearance can be maintained. Otherwise, consider oversized pistons.
What should I consider when selecting piston compression ratios for my CA18DET?
When selecting piston compression ratios, consider your engine's intended use, boost levels, and fuel quality. The 8.5:1 and 9.0:1 options provide different performance characteristics, with higher compression typically offering better power at the cost of increased risk of knock.
What happens if I have a piston to bore clearance issue with STD bore pistons?
If there is a piston to bore clearance issue with STD bore pistons, we will not offer an exchange or refund. It's crucial to ensure that the clearance specifications recommended by the piston manufacturer are adhered to.
How long does it take to receive CP Pistons if they are not in stock?
If CP Pistons for CA18DET engines are not in stock, they can take up to 2 weeks to arrive, as these are shelf stock items.
