Hi guys! I have a 2002 Civic, 1.6 Vtec. And the engine code is "D16W9". The company says its a Vtec 3 version. The engine bay is pretty much the same as those new 1.7 Vtecs avialable in USA and other countries, i.e. no plug wires etc.. but I guess the size is smaller.

Does anyone here have some advice for performance upgrade on this motor?

Any kinda help would be appreciated!
