what sucked me into mitsu 4s, was riding in a 2.0 sohc starion many years back. Silky smooth motor
Later learned it was the balance shafts at work. I've never eliminated em and hope not too
Once shafts and bearing look good, they stay, but...... If u liked your 2.4 results
2.6 testimonials range from: "i feel more hp > no difference > buzziness felt thru shifter > bolts loosening themselves"


Bshafts are for 2nd order natural harmonics. Engine balancing won't address that
Forged pistons won't make the g54 a "performance build" either. Still the same old 6000rpm forklift motor
