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).
