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 CP forged pistons in the TB48 kit?
Bore clearances for CP forged pistons typically range from 0.0015" to 0.0025" depending on your application and intended use. It's crucial to consult the manufacturer's specifications and adjust based on your engine's operating conditions.
Can I use the Spool TB48 conrods with other piston brands?
Yes, the Spool TB48 conrods can be used with other piston brands as long as the piston pin diameter and overall dimensions are compatible. Ensure that the conrod's big-end and small-end sizes match the specifications of the pistons you intend to use.
What is the recommended torque specification for the ARP2000 bolts on the TB48 conrods?
For the ARP2000 bolts included with the TB48 conrods, the recommended torque specification is around 55 ft-lb when using ARP Ultra-Torque lubricant. Always verify with ARP's latest instructions for the most accurate guidance.
What machining processes are necessary for the TB48 conrods and pistons?
The TB48 conrods may require big-end honing to ensure proper fitment on the crankshaft journals. Additionally, the CP forged pistons will need correct bore clearance and ring gaps set by the engine builder to ensure optimal performance.
How long does it typically take to receive the custom CP pistons if they are not in stock?
If the custom CP pistons are not in stock, the typical turnaround time is around 6-8 weeks. It's advisable to plan your build timeline accordingly to accommodate this lead time.
