I'm a little confused on tracing this motor. I bought it from a company in miami called alljapaneseengines.com. Heres what it came with: B16A stamped on the block with a serial number beginning with a 6. P2T OBD2 ECU (although myself an my friend who is a mechanic could not find a 2nd O2 sensor plug, and the CEL does not come on. Complete uncut right hand drive harness. A small blue metal plate written in half Japanese, half English that says GF-EK4 type SI. So... A B16A stamp and obviously a right hand drive harness, it's not USDM. Duh. But... I thought only the USDM SI came with a P2T ECU. And I did some searches on Yahoo and a GF-EK4 came up as a 4 door Civic "Ferio". What the hell is that ? And that was only on 2 sites, cause all the others with that code came up in Japanese so I couldn't read it. But other searches I've done with my combo show the VTI, which is like European or something, right? And where the hell is the plug for my 2nd o2!!!!!????? How come I'm not throwing any codes- one site I read said a JDM ECU won't search for a 2nd O2. ?????? I'm just curious as to what exact car this engine came from. Anyone?
