What bolts do these conrods use and how should I tighten them?
These rods use ARP conrod bolts, usually ARP2000 as standard with L19 or CA625+ available on some models. ARP2000 bolts are generally torqued to around 55 ft-lb for 3/8 inch and around 75 ft-lb for 7/16 inch when using ARP Ultra-Torque lube. L19 bolts must be tightened by stretch, not torque. Always refer to the latest ARP instructions for exact specifications.
Do these conrods have a horsepower rating or warranty?
No. Like other performance rods, they do not carry a horsepower or performance warranty. Spool warrants workmanship before installation, but once fitted, power handling depends entirely on machining, clearances, tuning, fuel, boost level and rpm.
Do the big end and small end need machining?
They often do. Crank journals and pin bores vary between engines, so your builder should measure the big end oil clearance and small end pin clearance and hone as required before assembly.
What is the recommended machining process for the Spool SR20 H Beam Conrods?
While the Spool SR20 H Beam Conrods are designed as a direct fit for Nissan SR20 engines, it is advisable to check the big-end and small-end sizes for proper fitment. Depending on the specific engine and its condition, honing may be required to ensure optimal clearances.
What are the benefits of the two-piece forging design in these conrods?
The two-piece forging design of the Spool SR20 H Beam Conrods enhances strength and durability by allowing for better alignment and load distribution. This construction method also contributes to the overall weight reduction while maintaining structural integrity under high-stress conditions.
Are there any specific installation tips for the Spool SR20 H Beam Conrods?
When installing the Spool SR20 H Beam Conrods, ensure that the dowelled caps are properly aligned for precision fitment. It is also essential to follow ARP's latest instructions for bolt torque or stretch specifications to achieve the best performance and reliability.
What type of power levels can the Spool SR20 H Beam Conrods handle?
The Spool SR20 H Beam Conrods are capable of supporting power levels exceeding 1000 RWHP, provided that the engine is properly built and tuned. Reliability will depend on factors such as machining tolerances, fuel quality, boost levels, and RPM.
Do I need to use specific bearings with the Spool SR20 H Beam Conrods?
No bearings are included with the Spool SR20 H Beam Conrods, so you will need to source compatible bearings separately. Ensure that the bearings match the specifications required for your specific SR20 engine setup.
