there are some differences
old palio 1.2 has 4-2-1 manifold header units before cat. in nv the cat con is fitted immediately after the ex manifold
the ecu progamme is different ,oldies have d8 where nv has d9 series
the shift of power mode is earlier in old palios than the nv so power delivery<should we say torque > is better in oldies, the a/c function is different in nv,
blower is different in nv
so even though the power and torque values are same for both the engines. the fashin in which they actually deliver on road are worlds apart
