wats your suggestion,different displacement engine will have different gear ratio n final drive.
however, ppl do use bigger cc engine but retained their lower ratio gearbox, so it pulls much better and torquier.
factory made gbox ratio to match the engine displacement, their goal is to output optimum power n fuel saving, not performance or acceleration.
example, if using 4g13 gbox with 1500cc engine, 1st and 2nd gear can wheel spin like nobody biz, and playing between 100-170 is fun, but maximum is about 170kmh.
if using 4g15 gbox with 1500cc engine, 1st gear wheel spin only, 100-170 is not as fun as 4g13, but better top speed 180kmh++
but some claimed the new robocop design saga with 4g13 engine n its gearbox can hit 180kmh, maybe their gbox also different again. have to check the gearbox code.
anyway, 4g13 and 4g15 gbox codes are different
if i want to still used my 4g13p engine..
do i need to change my gbox to 1.5 cc or 1.6 cc ones..
or just maintained it..
currently im using iswara lmss..
wif simple mode..
