Yong_5290,

My car was previously Proton Wira 1.6XLi (A) A/B with stock 16V MPI SOHC 4G92P engine. Now convert to 4G92P DOHC with 4G91 head, change also the gearbox to 4G91 (Close ratio according to mechanic). The rest including ECU / TCU also use back original one. Will it got problem? But I found out the engine was more quiet than SOHC except the valve lifter. It is true?

Current my FC in city drive (100% city) was up to 10KM / Liter but highway really crazy save, up to 16KM / Liter (100% Highway, 90KM/H ~ 100KM/H)

Anyway to make FC reach 12KM / Liter?

93 head can tarik a bit longer, the head is slightly higher than 92 head ..
but 92 head can achieve max tork faster (more pick-up) as it is shorter ..

so, if you looking for max velocity, 93 ..
if for pick-up, 92 ..

in a drag race,
92 head VS 93 head ..

if you can switch gear nicely and faster achieve max tork, you win .. (short distance)

real facts: my bro use 4G93p DOHC, i use 4G92p convert to DOHC, i win .. hehehe
