Hello everyone. Just bought my self a stock MCS 163hp. First thing I did was to change oil w/filter, air filter, cabin filter, fuel filter and spark plugs, checked the connections between coil and spark plug wires. Then I did the One-ball exhaust mod. Tomorrow I'm changing the SC pulley to the Alta 17% reduction pulley, and shorter belt. What do you guys recommend as the next upgrade for my MCS? Looking for 190whp. Regards Haakonnor. Norway (cold country).
It has 96000km on the clock.

Sorry for my bad English
