Can you explain what a "US OBDII" is? Also, what is meant by the "drive block (being) disabled?
By the way, I noticed that you are in Lawrenceville NJ and I'm just outside of Philadelphia and work in Princeton. Who's doing the install for you? and where did you find the motor? Thanks.

OBDII refers to the computer system. OBD I is a more simple system and has socketed chips that are easy to swap in & out. OBD II is more complex, and you need to unsolder, program, and resolder the chip during to reprogram. This makes it more expensive and more difficult to change the computer mapping.
Drive block is the alarm system on 993s, which is incorporated into the computer. It ties into the other systems of the car, and it must be disabled in order to run the engine after a conversion.
There are many good sources for engines, but I ended up buying mine from LA Porsche due to their price, availability, and warranty. Powertech, in Rockaway, NJ, is doing the installation.
