ok.... my brother in Hong Kong has a Civic SIR, which is a B16A... something like that...
but because fixing up cars is illegal in Hong Kong... but they are not really restricting it that hard ! although if the police asks u to pop the hood, then u r done.. !
they can basically lower their car, exhaust that is not TOO loud, and rims... that's the basic things ppl do in hong kong on almost every car... no matter what car

my brother wants his car to be faster... but he doesn't want to get caught, is there anything that can make ur car more faster and it cannot easily be seen even u pop the hood.... even an AEM CAI is not good... so basically it's internal stuff... like engine internals, but those are hell of expensive, is there anything else?? stroke the 1.6 L to a 2.0 L?? how do you do that anyways???

thanks alot guys !!!

 

Put a filter in the stock air box. Do some cams, higher compression pistons, nmaybe bore it out. Ignition wires that are black like the stock color. Intake manifold, throttle body. Injectors. Get an exhaust made here in the states that is not at all shiny, so it will look stock.....maybe a afc hidden to tune the fuel and VTEC....it almost seems like a jackson racing supercharger would work because they dont really look that different from stock, maybe you could have the "jackson racing" part grinded off....Maybe this will help, maybe not...

 

yea we were thinkng of Jackson racing SC... but... dunno yet.. haha...
anyways, thanks for the help....
looks like internals are the choices.. and intake manifold throtle body...
he changed his computer chip already.....
