Before my engine swap, I had run a 11.2 1/8 mile on a bone-stock 200,000 mile dx engine, with one cylinder only putting out 80psi compression and full interior, spare, etc. According to my g-tech, my 0-60 was like 10.1 seconds... after getting a header and intake, dropped to 9.1, then I got a catback exhaust and a race cat (straight through, basically a resonator), which dropped the 0-60 to a best of 8.1. Not too bad for bolt ons, but I never got it back to the track before I put in the B16.. now I can do 0-60 in under 7.
