hows everyone doing my name is chris im from massachusetts, i just buaght an 03 civic si, low milage, since i bought it i installled a k and n short ram system, and a greddy cat back exhuast, i purchased and installed a set of hp racing headers which was a mistake, they were very cheap the dc sports are on the way and now im stuck.

i need suggestion on what else i can do to release more performace out of the enigne, i would love to be able to have the 6000 rpm v tec kick in, could that be done by adding type s cams, or do you need a whole new dc5 head, also a stand alone engine managment system looks good its the apexi neo ill take any suggestions, im totally noob to this and i want to really get in to it, thanks

 

hey man join the club! I just bought an 02 si after my baby, 2000 lb. 96 ek 300 whp turbo monster was stolen this past december lol.......thats another story, anyways, I am in the running for another rebuild after rebuilding my ek's motor just before it was stolen, but there really isn't much to do with our k20a3's, they are great on gas mileage but lack real VTEC, installing a k20a2 head or head of equal performance will probably not be a good idea, our internals aren't as strong as or brother's rsx, I would suggest saving your money and putting it else where, on suspension perhaps, or even saving it for a better purpose, if you really want to get some more juice, better gas mileage, and be able to keep your mods I would get a JRSC, I plan on doing the same thing except with a k24 block at 11:1 with a k24a2 head and JRSC, should be fun...... but sorry to answer your questions, not worth it, save your money, if you have to, swap motors and you don't need an ems, but K-pro never hurts
