ok,to start things off,i think that i'm the member here with the slowest car,stock.it's a 7th gen civic dimension,D16 engine with 3 stage VTEC.i did perform the most basic of modifications:I/H/E,racing clutch and lightened flywheel.what put me off the most 'bout the engine though is that they assembled it with an intake manifold for a 1.5L civic.im thinking of buying a bigger manifold that would match the engine size.do you guys have any suggestions on how to make it a bit faster,at least?please?engine swap and changing the ecu would be out of the question,since money's a bit tight right now so i wanna make sure that the parts i purchase won't be a waste of money.thanks thanks thanks!
