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 torque specifications for the ARP 2000 bolts included in the Spool Drag Pro I Beam Conrods?
For the 7/16 ARP 2000 bolts used in the Spool Drag Pro I Beam Conrods, the recommended torque specification is around 75 ft-lb when using ARP Ultra-Torque lubricant. Always refer to ARP's latest instructions for the most accurate guidance.
What machining processes should I consider when using the CP Forged Pistons in this rebuild kit?
When using CP Forged Pistons, ensure that the bore clearance and ring gaps are set according to your engine's specifications. It's crucial to check that the pistons fit correctly in the RB30 block and that the ring gaps are appropriate for your intended use, especially if you're planning on higher RPM or boost levels.
Can I use this rebuild kit with any RB30 block, or is it specific to certain configurations?
This rebuild kit is specifically designed for the RB30 block when paired with an RB25 NEO cylinder head. Ensure that you have the correct components and configurations to achieve optimal performance and compatibility.
What are the compression ratio options available for the CP Forged Pistons in this kit?
The CP Forged Pistons included in this rebuild kit are available with a compression ratio of 9.0:1. This ratio is designed to work effectively with the RB30DET engine setup, but always consider your specific tuning and fuel requirements.
What type of oil do you recommend for breaking in the engine after using this rebuild kit?
For breaking in the engine after installation of this rebuild kit, we recommend using Joe Gibbs Break in Oil. This oil is formulated to provide optimal protection during the critical break-in period.
