Spool 2JZ-GTE 3.2 Litre Stroker Kit (Extreme Power)

Spool Toyota 2JZ-GTE 3.2L Stroker Kit – EB40B Billet Crankshaft

The Spool 3.2 Litre stroker kit for the Toyota 2JZ-GTE is designed for high-power street and motorsport applications where torque, response, and long-term reliability are critical.

At the heart of this kit is the Spool 91 mm EB40B billet stroker crankshaft, engineered for extreme strength, excellent fatigue resistance, and superior performance under high cylinder pressure and sustained high RPM operation.

Kit Includes

• Spool EB40B Billet 91 mm Stroker Crankshaft
  True billet construction, precision CNC-machined from EB40B core stock, nitrided, fully balanced, and final ground

• Spool DragPro I-Beam Forged Connecting Rods
  Supplied with ARP L19 bolts as standard. Optional downgrade to ARP2000 bolts for lesser RPM requirements
  Optional downgrade: Spool H-Beam connecting rods with ARP 2000 bolts, L19 or CA625+

• CP-Carrillo Custom Pistons
  Custom manufactured to suit the application
  Available in a range of bore sizes and compression ratios
  Pistons supplied complete with rings, pins, and locks
  Lead time: approximately 5–8 weeks

• 300M Steel Gudgeon Pins
  0.250" diameter supplied as standard
  Optional  downgrade: 9310 0.250" or 0.200" pins for lesser power applications

Performance Benefits

The increase in stroke to 91 mm raises engine capacity to approximately 3.2 litres, delivering substantial gains in usable performance:

• Up to 50% increase in torque (application dependent)

• Significantly improved low and mid-range power

• Earlier turbo spool and stronger throttle response

• Increased peak power potential

This makes the 3.2L EB40B stroker combination ideal for large-frame turbo builds where torque and drivability are just as important as top-end power.

Important Fitment Note

Note: Depending on the block casting and rod choice, minor conrod-to-block clearancing may be required during assembly.

EB40B vs 4340 – Crankshaft Material Comparison

Summary:
4340 billet steel remains an excellent choice for many high-performance 2JZ builds.
EB40B is a premium upgrade, selected for engines operating at extreme power levels, high boost, and sustained high RPM where fatigue resistance and long-term reliability are critical.
