THAWA: You got it.
Zendriver: You need to ask around for the local honda engine swap guys. It should actually be easier for you, since subaru engine swaps are so rare (except for Vanagon conversions)
I could be wrong but I dont think they could tell if your EJ22T came from a 91-94. Even the board members might have a hard time if you asked them to.
Check with what the DMV requires on an Engine Change (swap is a foreign word to them). For me Im lucky enough to have purchased the entire vehicle, so I have the Title and all.
Here is a useful (though a little tough to read at first)
4161. (a) Whenever a motor vehicle engine or motor is installed, except temporarily, in a motor vehicle which is identified on the ownership and registration certificates by motor or engine number or by both the motor and frame numbers and subject to registration under this code, the owner of the motor vehicle shall, within 10 days thereafter, give notice to the department upon a form furnished by it containing a description of the motor vehicle engine or motor installed, including any identifying number thereon and the date of the installation. The owner of the motor vehicle shall also submit to the department with the notice the certificate of ownership and registration card covering the motor vehicle in which the motor vehicle engine or motor is installed and evidence of ownership covering the new or used motor vehicle engine or motor installed and such other documents as may be required by the department.
(b) Upon receipt of motor vehicle engine or motor change notification and other required documents, the department shall assign a distinguishing vehicle identification number to motor vehicles, other than motorcycles or motor-driven cycles registered under a motor number or motor and frame numbers. When the distinguishing vehicle identification number is placed on the vehicle as authorized, the vehicle shall thereafter be identified by the distinguishing identification number assigned.
9257. Every notice of the installation in a vehicle of a motor vehicle engine or motor required to be filed under Section 4161 shall be accompanied by a filing fee of two dollars ($2).
And the best of all
4163. The owner of three or more motor vehicles is not required to notify the department or to pay the fee required under Section 9257 when motor vehicle engines or motors owned by him are installed in or transferred between the motor vehicles owned by him until the motor vehicle is sold, transferred, or otherwise disposed of by him.
Here is a picture of the tag you get, notice you have no mention of the engine specifics (only size and such)
