Hey i just got myself i 2000 civic Si with the b16a2 in it.
I was wondering....i want to make it a 12.8 second car...........how would i do this Turbo? Supercharger? how much PSI of boost? ummm new internals <lower comp rings, pistons> you know anything than can get me to my quest..... a 12.8 or lower second car.

THank you for ALL suggestions peace....

build internals first. New sleeves, forged pistons and rods. Turbo kit, with big turbo, T3/T4 should do the job. Not sure how much boost you'll need to run, but with basic block internals upgraded you can run a pretty good amount. It probably won't get you into the 12's, but you'll be close and it's a good start.

AEBS makes good sleeves, so check them out. Crower makes some good rods, look at the 4340 Steel Billet Connecting Rods, not the econo billet rods. Crower also makes some good turbo cams. GScivic7 is right, start with internals first...build the internals up so they can handle the boost you are gonna throw at it. Arias, Weisco, and JE makes some good pistons. Don't forget the vavle springs, retainers, and vavles also.
