Yes, i know that. In 900 motor is lengtwise & 9000 motor is crosswise. How is in subarus? But 900 isn't McPherson suspension system and that's more difficulty.
I can do lots of 9000 motor, car doesn' go to registery. That means it will only "fly" in the track .
In 96 4wd, used subaru 4wd system. That's why i need your expertise in 900 or 9000 making 4wd car.
