From his Link:
Good ol' D16a6. I had an '88 DX with a d15b bottom end with a d16z6 head and PM9 pistons. Shaved the head and added a bc stage 3 cam with springs and retainers. CAI + D16y8 intake + 4-2-1 header and a test pipe = screaming 14.8 1/4 mile.. It was all ~450 to get there too.
Get traction bars, and a new trans mount. Fill the trans mount and rear engine mount. You'll be much better, trust me.
