Engine Internals


Crower, who needs them? At the PRI show in IN, we truely learned about these wonderful rods. We had stocked and used them for a while. Because of the luck of how Nissan's factory rods are designed and Eagle's replication of them with these "I" beams, these Eagle rods are good for 800HP. Yes, that's right. Attribute it to luck or what-not, but it's true. Eagle SR20 I Beam Rods $359, For tech support, call JGY as Eagle is not known for their "SR" knowledge.


Crower SR20 $689


ARP sr20 Headstuds. When removing the head on a motor, it is wise to measure the head bolts as they stretch over time and may not be able to be reused. ARP head studs are the best out there and are recommended for and build up on the sr20. $109


ARP Main studs. hold main caps around crank. better then reusing 11 year old stock bolts......$95


APEX'i Cylinder Sleeves. recommended for motors that are using larger then 86.5mm pistons because cylinder walls get thin and weak.... $267


JGYCustoms now has an in house torque plate exclusively for SR motors to be used when boring and honing out blocks. Please inquire for boring service.


CP Pistons are Available in different bores and compressions, specify when ordering - $499. note...These are some of the best pistons on the market for SR motors. We deal very closely with CP and really enjoy their attention to detail and quality control. We can special order any size piston set for you for $530......such as 12/1 compression with 92mm bore.


JE Pistons are available from other places than JGY. We really like the quality of CP's and only use them for our motor build ups. We no longer carry JE's.

Boring with use of torque plate - $350
