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 bore clearances for the Ross Racing pistons in the RB20DET rebuild kit?
For the Ross Racing pistons, you should aim for a bore clearance of approximately 0.0015" to 0.0025". This ensures proper thermal expansion and prevents piston seizure under high load conditions. Always verify with your specific engine setup and conditions.
What is the recommended torque specification for the ARP2000 bolts included with the Spool conrods?
The ARP2000 bolts should be torqued to around 55 ft-lb when using ARP Ultra-Torque lubricant. Always ensure to follow ARP's latest instructions for the most accurate specifications.
What compression ratio options are available with the Ross pistons in this kit?
The Ross pistons in the RB20DET rebuild kit are available with a compression ratio of 9.0:1. This ratio is suitable for a balance of performance and reliability, especially when tuned for boost.
Do the conrods require any specific machining before installation?
Yes, the Spool H Beam conrods may require big-end honing to achieve the correct fit on the crankshaft journals. It's essential to check the clearances and ensure proper fitment before installation.
What type of head gasket is included in the RB20DET rebuild kit?
The kit includes a Cometic MLS (Multi-Layer Steel) head gasket, which is designed for high-performance applications. Ensure the cylinder head and block surfaces are finished to the correct RA surface finish for optimal sealing.
