This is the first supra I've owned (95 2jzge with turbo) and I'm not very familiar with them. I took the engine out and had it rebuilt. I got it back and went to reinstall the engine and now have a threaded hole in the driver's side of the engine (see pic). I talked to the place that rebuilt the engine and they couldn't offer any info about what happened to what went in there. (my best guess is the coolant temp sensor) Any info about what might go there would be greatly appreciated.
