US Spec 2JZ-GTE?
I googled and searched like crazy for this answer, but I'm trying to figure out which motor I've got in my car. I was told that I had gotten a JDM motor, and have read about the differences between the two engines, but am unable to verify which one I got. The motor is already in the car and running, so I can't identify which turbos are on the car (steel or ceramic). The one thing I did notice was that my car has an injector resistor pack. It wasn't added to the car either, as it's definitely part of the factory harness. I was told that the JDM TT engine, does NOT have one, but that the US spec does. (High imp vs Low imp). Is this a for sure way to tell if I have a US spec engine? Is there any other obvious way to figure this out? Thanks.

Injector resistor box means 550 injectors. 550 injectors are from a USDM motor. If you say the resistor box is part of the harness, then it means you probably have a usdm harness. You probably have a JDM motor, with USDM parts.

Well, my TB says trac control, not TRC, so I guess I can safely assume it's US spec, but damn, I'd hate to turn the boost up and fry my turbos! I thought that most swapped cars were the JDM 2J's, not US spec, so I had figured I was part of the majority, not minority. Oh well, I guess I'll find out when I crank it up!
