Subaru BRZ FA20 Spool H Beam Conrods and CP Forged Pistons

Kits usually include pistons, rings, rods, bearings and related hardware depending on the engine family. Check the listing for exact inclusions.

Yes. The block must be honed and all clearances checked and set by your builder. Assembly should only occur after full measurement and verification.

For the CP pistons in the FA20 kit, a typical bore clearance of 0.0015" to 0.0020" is recommended. However, this can vary based on the specific application and operating conditions, so always consult with your engine builder for precise specifications.

The ARP2000 bolts included with the Spool conrods should be torqued to approximately 55 ft-lb when using ARP Ultra-Torque lubricant. Always verify with ARP's latest instructions for the most accurate specifications.

Yes, the Spool conrods and CP pistons are designed for high-performance applications, including high boost setups. However, reliability will depend on proper machining, clearances, tuning, and fuel quality. Ensure that your engine is built to handle the increased stresses associated with higher boost levels.

Yes, the ring gaps for the CP pistons should be set according to the intended use of the engine. A common starting point for a performance application is 0.004" to 0.005" per inch of bore diameter. Adjustments may be necessary based on boost levels and RPM, so consult with your engine builder for optimal settings.

The Spool FA20 conrods may require big-end or small-end honing to ensure proper fitment with the crankshaft and pistons, as factory tolerances can vary. Always check clearances and perform any necessary machining to achieve optimal performance and reliability.
