wrong, playa. ive got an obd2 p72 and it runs great.
and you dont use the plugs from the obd1 harness...everything except the distributor will plug right into the obd2 harness.
youre gonna have to get a 96-98 gsr distributor, too.
but here's a general parts list for you:
1. motor/transmission
2. 96-98 civic EX harness
3. 99-00 Si axles
4. 99-00 Si rear, a/c, and front transmission mounts
5. 99-00 Si intake manifold (if youre using a non-obd2 b16)
6. 96-98 gsr distributor
7. 96-98 gsr P72 ecu (or a p20/p30 and a jumper...if you use an obd1 ecu/jumper you wont be able to pass emissions in some places, a lot of places plug a reader into your ecu data port thingie, and if youve got an obd1 ecu it'll show up as you having no ecu at all and you'll fail emissions. dont worry, my obd2 p72 runs fine)
8. any 92-up b-series shift linkage. go for the linkage from an integra ls, they're much cheaper than del sol vtec's, gsr's, or si's
9. 99-00 si exhaust manifold/downpipe/cat. youre gonna have to run wires from the o2 sensor thats after the cat, and lengthen the wires from the o2 sensor that's before the cat.
10. 96-up b-series alternator (if you have an obd1 motor)
im pretty sure thats everything...
OH youre gonna need an si upper radiator hose, too...
