This mod is for Campro, but for CPS, I think further "exploration" need to be done as CPS is totally different from Campro, right?

humm... totally different??? all na engine do same mod to gain power..... but now all can custom already... no need to wait oledy.... have money go for it....
- increase cc - bigger piston(oversize campro piston), stroker
- increase compression ratio - hi compress piston (can use campro 1.3 piston), skin head, thin metal gasket
- better flow efficiency - port & polish ,valve necking,3 angle valve cut, exhaust system , intake porting ,tb , camshaft, bigger valve etc
- tune afr & ign timing to optimum - unichip is the cheapest, megasquirt(this maybe need to change to old style throttlebody)
- cool air intake
- lighten - rim, body, moving part (crankpully, flywheel) etc
- low viscosity lub oil. ( engine oil & gearbox )
- remove unwanted load from engne ( remove powersteering, aircond compressor )
- gearbox ratio - change final drive or individual gear
- tyre circumference
- sharp edge crankshaft - need to dynamic balance
- more efficient engine - do piston ceramic coating, sleeve coating, race engine bearing
- colder engine bay - thermal warp exhaust or ceramic coating
- better electrical system - grounding & voltage stabilizer ( to ensure engine running at optimum )
i think thats all mod to gain power from na engine.... maybe still have some miss..
we oso need to do sporting mod to ensure engine running in safe condition...
- more cold heat range spark plug - faster transfer heat from combustion chamber
- radiator
- ensure engine no knocking
- metal gasket ( no need to worry, campro already metal)
- low resistance spark plug cable or hi power coil - to ensure engine no miss firing coz of hi compress engine
- use hi octane fuel -less knocking & preignition
- ensure no sharp edge in combustion chamber - can coz preignition
- etc
hope this can help...
