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 SPL-RB26-H-CP kit?
The CP pistons in the SPL-RB26-H-CP kit are available in compression ratios of 8.5:1 and 9.0:1. Choose the ratio based on your intended power goals and boost levels.
What bore sizes do the CP pistons support in the SPL-RB26-H-CP kit?
The CP pistons in the SPL-RB26-H-CP kit are designed for bore sizes of 86.5mm and 87mm. Ensure you select the correct size to match your engine's specifications.
What type of fasteners are used in the Spool RB26 conrods, and what are the torque specifications?
The Spool RB26 conrods come standard with ARP2000 fasteners. For 3/8" bolts, torque them to around 55 ft-lb, and for 7/16" bolts, torque to around 75 ft-lb using ARP Ultra-Torque lubricant.
Do the conrods in the SPL-RB26-H-CP kit require any specific machining?
Yes, the conrods may require big-end or small-end honing to ensure proper fitment due to factory journal and pin size variations. Always check clearances during installation.
What is the recommended break-in oil for engines using the SPL-RB26-H-CP kit?
We recommend using Joe Gibbs Break in Oil for all new engines built with the SPL-RB26-H-CP kit to ensure proper lubrication and protection during the initial break-in period.
