Spool Toyota 1FZ-FE 4.8L Stroker Kit

Spool Toyota 1FZ-FE 4.8L Stroker Kit

This kit includes:

• Spool Billet 4340 101mm Stroker Crankshaft
• Spool H Beam Forged Conrods with ARP2000 7/16 Bolts
• CP Custom Pistons with rings pins and locks. Pistons can be ordered in any bore size, any compression ratio and to suit turbo or naturally aspirated applications
• Full billet 4340 Nitrided and Balanced Crankshaft

With the increased cubic capacity from the 101mm 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.

Note: If conrod to block interference occurs, slight clearancing may be required.

Available options

• Piston Diameter: +0.5mm; +1mm; STD (Special Order)
• Conrod Bolts: ARP2000; ARP L19
