engine swap B18c!!!!!

alright guys! I need help. I have a 1995 integra that i finally decided to soup it up. I got a great deal on some of the stuff...but my mechanic was wrong on some combination of parts. Bottom line! I now have a B18c 2001 OBDII, along with that the intake manifold from the same engine. As part of the deal, i also have a 1995 GSR PORT AND POLISH INTAKE MANIFOLD THAT I REALLY REALLY WANT TO GET IT INSTALL. This part doesn't go quite right b/c of a hole that i can't figure out what it does. My machanic mention something making the car idol really inconsistently.....please anyone with this info HELP ME! OR IF YOU'RE INTERESTED IN BUYING THE PORT AND POLISH INTAKE MANIFOLD FROM ME...PLEASE EMAIL ME [email protected]
