So I got this car from a friend, I know zero about Honda's, or anything about engines for that matter. So please, no sarcasm. He already swapped it out to a D15B, the tranny, the ECU, and an LSD. Also, some wal-mart looking brand CAI. Other than all that, it's stock. Since I was unemployed when I got it a couple of weeks ago, all I've done is stripped the interior and all the extra brackets and bolts leftover. What are some other cheap things I can do to lighten it up. Also, are there any websites that sell bolt-ons for D15Bs, or if that's not available, so brands that make the peformance parts. Thanks for any help!
