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.
Top-of-the-line STEP3 model added to COMPLETE ENGINE RB28
High thermal conductivity valve seat inserts and guides for use at high horsepower.
The exhaust cam has 280-degree duration to ensure more power at the high RPM range.
V-CAM is used to supplement torque in the low RPM range for a big turbo.
Specially designed 36-tooth crank angle sensor and cam angle sensor for V-CAM improve signal accuracy in the high RPM range.
Titanium retainer, strengthened valve spring, high lift camshafts and strengthened stem seals upgraded to sustain high end performance
CNC machined combustion chamber to decrease knocking
High-volume oil pump to ensure lubrication of the engine on a whole range of RPM
NOTE: HKS recommends using HKS Racing Pro 10W50 engine oil.
