High budget – best power delivery
#1 – Lightweight flywheel (ignor step 1)
#2 – Heavy-duty clutch
#3 – Lower final drive
#4 – JDM Intake manifold + CAI only
#5 – Header + S2000 cat + cat-back system
#6 – Ported head / Spec A2/B/C camshafts / valve springs/ Titanium retainers / adjustable cam gear - exhaust only / fuel pump / Forged pistons / Forged rods (For over 9000rpm) / injectors & fuel pressure regulator / ECU / dyno tuning / heavy duty engine mounts.
Nb: Additional head work that can/may need to be done includes shaving of rocker arms for cam clearance, re-shaping of valves, combustion chamber re-profiling.
Power output: 156+kw @ wheels (Dyno dynamics – shootout)
