When I was wiring up a 2JZ for a friend I was shocked when I saw the map sensor. It wasn't anything like the GM version, it's a simple NPT threaded sensor like the rest of the sensors on the engine. It was part of the old AEM V1 ecu kit for the supra, so not sure what car it originally came on (I think supra's had MAF sensors originally so it was not from the car itself).
Either way, it completely eliminated the need for a vacuum line, and look much cleaner because it could hide under the plenum with the air intake temp sensor.
