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 SR20 rebuild kit?
The CP pistons in the SR20 rebuild kit are available in several compression ratios: 8.5:1 and 9.0:1 in standard bore sizes of 86.5mm, 87mm, 88mm, and 90mm. Additionally, there is an 11.0:1 compression ratio option available in 86.5mm and 87mm bore sizes.
What are the recommended torque specifications for the Spool conrods included in this kit?
The Spool conrods come with ARP2000 bolts, which should be torqued to around 55 ft-lb for 3/8" bolts and around 75 ft-lb for 7/16" bolts using ARP Ultra-Torque lubricant. Always refer to ARP's latest instructions for the most accurate specifications.
Do the conrods require any specific machining before installation?
Yes, the Spool conrods may require big-end or small-end honing to ensure proper fitment due to factory journal and pin size variations. It's essential to check clearances before installation.
What type of bearings are included in the rebuild kit, and what sizes are available?
The rebuild kit includes ACL Race Series main bearings and big end bearings, available in standard size or 0.25mm oversize. Choose the appropriate size based on your engine's specifications and machining.
What oil is recommended for break-in after installing this rebuild kit?
For optimal performance and protection during the break-in period, it is recommended to use Joe Gibbs Break in Oil for all new engines built with this rebuild kit.
