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 compression ratios are available for the CP pistons in the RB26 rebuild kit?
The CP pistons in the RB26 rebuild kit are available in two compression ratios: 8.5:1 and 9.0:1. Choose the ratio that best suits your performance goals and intended use.
What machining is required for the Spool H Beam conrods in this kit?
The Spool H Beam conrods may require big-end or small-end honing to ensure proper fitment with your crankshaft and pistons. Always check the clearances as per your engine's specifications.
What is the recommended torque specification for the ARP2000 bolts included with the conrods?
For the ARP2000 bolts included with the Spool conrods, the recommended torque specification is around 55 ft-lb for 3/8" bolts and around 75 ft-lb for 7/16" bolts when using ARP Ultra-Torque lubricant.
Do I need to balance the crankshaft with the full rotating assembly when using this rebuild kit?
Yes, it is essential to balance the crankshaft with the full rotating assembly to ensure smooth operation and reliability, especially when using performance components like the Spool conrods and CP pistons.
What type of head gasket is included in the RB26 rebuild kit?
The rebuild kit includes a Cometic MLS head gasket, which is designed for high-performance applications and requires a proper RA surface finish for optimal sealing.
