Actually I looed into it and in a breakdown of the motor the 1GGTE and the 7M share a lot of parts. I know the intake manifold on the passenger side of that car is the same and the block is too just the head and stroke are different. Just as I have found the 1JZGTE and the 2JZGTE share almost every part except the crank rods and pistons. The head is also slightly different. What I was told by a Japanesse friend of mine is that the 1GGTE is a redesigned 7MGTE with twin turbos if you see one without the exhaust manifolds and the pipeing on top you will see some similarities.
