What is included in a typical Spool engine kit?
Kits usually include pistons, rings, rods, bearings and related hardware depending on the engine family. Check the listing for exact inclusions.
Do I still need machining with a full engine kit?
Yes. The block must be honed and all clearances checked and set by your builder. Assembly should only occur after full measurement and verification.
What are the recommended clearances for the CP pistons in the FJ20 rebuild kit?
The recommended bore clearance for CP pistons typically ranges from 0.0015" to 0.0025" depending on the application and intended use. It's crucial to consult with your engine builder for specific clearances based on your setup and the type of fuel you plan to use.
Can I upgrade the ARP fasteners in the Spool H Beam conrods?
Yes, the Spool H Beam conrods come standard with ARP2000 bolts, but you can upgrade to L19 fasteners for enhanced strength and reliability, especially in high-performance applications.
What is the recommended torque specification for the ARP2000 bolts in this kit?
For the ARP2000 bolts used in the Spool H Beam conrods, the recommended torque specification is around 55 ft-lb when using ARP Ultra-Torque lubricant. Always refer to ARP's latest instructions for the most accurate guidelines.
What type of head gasket is included in the FJ20 rebuild kit?
The kit includes a Cometic MLS (Multi-Layer Steel) head gasket, which is suitable for high-performance applications. Ensure that the cylinder head and block surfaces have the correct RA finish for optimal sealing.
How long does it take to receive custom CP pistons after ordering?
Once ordered, the custom CP pistons typically take 4-5 weeks to manufacture. Be sure to specify your desired compression ratio and bore size when placing your order.
