For interests sake, a stock JDM K24 on a rolling dyno
~160,000kms on the engine, unknown compression
Tubular exhaust header
2.5" exhaust (around 1m long after headers)
S2 pro street intake manifold and 72mm tb
Removing the intake picked up ~4hp so that needs improvement
This same above setup made about 305whp with built internals, big cams and ported PRB head.
VTC adjustment didnt seem to make much difference, had the most power at about 20degrees from 4500rpm. Only lost a little bit of power going either way from there.
VTEC switching at 6000rpm
MBT at 25deg advance on 98MON
