I'm getting ready to do my swap so I'v been doing alot of research the past few months and I'v heard good things about the B16a2 out of the 99-00 si into my 97 dx. But lately Iv been considering just buying an already built engine, possibly with a turbo on it. For a swap to be legal I know the engine has to be the same year or prior to your car. But I'm wondering how tough it is to put for example a built 92-95 si B16 into my car. Is the OBD the same? and would the wiring harness matchup? and would the response to this be the same as for an older B18? Mainly what it all comes down to is money and If i can get an older built engine for a little more than a stock newer engine, if it works, then why not. any advice is appriciated.
thanks.
