the manifold is the d15b vtec version which is been ported out on the intake and the throttle body side, the throttle body is a b18c throttle body, if you look at this picture you can see the b18c throttle body is alot bigger than the d15 jdm intake, even thow ive ported it out. the reason behind using the b18 throttle is that is where the biggest intake restriction is.

as seen in this picture.



also the rear drum brakes work great, so people should never diss them, heavy trucks which weigh over 5000kg use drum brakes to stop., and we are talking the front brakes. besides that the biggest issue with any stock brake setup is the overheating on constant braking. and what makes things worse is if the car is heavier, example, my honda legend will generate more heat and more warping on its brakes due to the weight and braking of the car, but since the honda city ga2 is almost like a motor bike, brakes rarly get hot.... remember some of the fastest bikes weight between 200kg to 400kg. i mean a extra 250kg and your at my car. understand now? - ppl that flood my sale forum without any true understanding or logic. enjoy your answers.,
