First off lets look at the facts.. a 300+ hp awd car whooped a pretty much stock 170 hp civic but only after 85mph.. you got a great base.. Forget turbo.. Spray it and forget it man.. you can make sure as much hp with a nice 50-75 shot of nitrous then you could on a turbo... Specially if you dont plan on building your setup if you plan on building turbo all the way.. but stock internals.. do it the cheaper faster way... i've seen stock gsr's with i/h/e break 14.9-14.8 with nitrous a 75 shot dry.. they brought their times down to 14.0-.13.8 with the right tuning and good parts your set with a nitrous setup..Do your own search see how deep your pockets are and go from there.. you can't just do a turbo setup in a week neither.. gotta piece it to gether and what not same with a nitrous setup or n/a.. just see what you like best.. everyone has their two cents and thats mine.. Btw..
CTR Cams,skunk2 intake manifold w/ hondata gasket.. and nice i/h/e and chipped ecu and you wouldn't be getting walked by that sti anymore.. on that setup of a n/a gsr.
