yea so I got 99 si. Right now it's in the shop geting an OEM Front end, and a Carbon Fiber Hood.. Well since this is my DD, I want it to have a little bit more pep, I'm not looking for a full out race, but something more faster... turbo whould be nice but its costly.. and I want to keep my car clean,(Intercooler is too much attention.) Supercharger might get the job done.. but that whining sound it makes is gay.. My other options are a GSR block with CTR Pistons, a good Header, ITR Cams, and maybe a 50shot of n2O. :bomb IDK but sometimes I wish I got a EK hatch... friggin Si's are heavy.. So any suggestions??
