What's up everyone, I just bought a 2000 ex sedan and i had a few questions. The car came with a jdm vtec d15b. It is running a p2p ecu, and ex s40 trans. There are a couple plugs that are not connected, and I suppose it's cause it's a obd1 engine using the stock harness that came with the car. There is also a vacuum hose that has a bolt in it, no idea what that is for. The car has a bogging noise, my guess is one of the 02 sensor, or ecu? there is no primary near the dc headers that the previous owner installed. Is the car fine running p2p or should I get a p08 or p28?. There is a space on top the transmission that looks like something used to be there. The accessory drive belt is in bad shape as well so what belt for what us engine will work with the d15b? any help will be appreciated.
