thanx nighthawk. i finally got off my lazy butt and followed everyone's advice and did my research. i agree with you about doing the hondata last because of all the mods available for the car. as far as the toda racing kit... well lets just say that is out of my league right now. ha ha. 2300 dollars, geez talk about bankrupt. they reprogram your ecu as well; would i even need the hondata? i just bought 4-2-1 dc sport header (ceramic). next on my list will be to get an intake manifold and a hondata gasket. i think when i have that in place then i will get the clubrsx hondata. not ready for the toda racing kit yet. also , what do u think about the aem true pwr pulley kit. is that worth getting? thanks for the help ppl
