Spool Toyota 2JZ-GTE 91mm stroke crankshaft (4340)

Toyota 2JZ-GTE 3.2L Billet 4340 91mm Stroker Crankshaft

The 2JZ GTE engine in its factory form has a 86mm bore and 86mm stroke, giving a displacement of 2997cc.

Using the 91 mm stroker crank, std length Conrods and Custom Pistons, the displacement is increased as follows:

• 86.6mm bore and the 91 mm stroker crank = 3285cc / 288cc increase
• 87.1mm bore and the 91 mm stroker crank = 3362cc / 365cc increase

The Spool 2JZ Stoker Crank is a true billet crankshaft machined from Billet 4340 core stock (not a cast forging blank that is final machined).

Each crank is machined from core stock 4340 on a CNC machine, then Nitrided and final ground.

With the increased cubic capacity from the 91mm stroker crank, increases of up to 50% in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.
