Engineered for the your build owner who demands the best, this premium materials upgrade delivers real performance gains by delivering measurable performance gains. At Jesse Iwuji Performance, every product we carry is vetted through the lens of NASCAR-level engineering — if it doesn't make the car faster, better-handling, or more capable, it doesn't make the cut. Designed for straightforward installation, this is a direct-fit upgrade that speaks for itself on and off the track.
Version 2 was released with an improved balance of intake and exhaust by adopting a big valve for the exhaust, and further improved intake and exhaust efficiency by optimizing the port profile and cutting the valve seat into an R shape to prevent delamination of the boundary layer.
Professional staff assembles the proven 2.8L STEP2 kit
CNC machined combustion chamber to decrease knocking
High-Volume Oil Pump to ensure lubrication of the engine on a whole range of RPM
Specially selected strengthened main bearings and connecting rod bearings
Grommet Head Gasket and Strengthened Stud Bolts for improved sealing.
High angle camshaft for improved high end performance
Reinforced valve spring to suppress surging at high RPM
Strengthened valve stem seals to maintain precise performance even at high RPM and high temperature
Improves intake and exhaust efficiency by optimizing the exhaust side big valves and port shape, and also measures against overheating with the sodium-filled valve.
Reinforced valve stem springs and titanium retainers are installed to suppress surging at high RPM.
Features separator to shuts out oil that flows out with blow-by gas from the cam cover.
