A turbo is spooled by how much air is shoved through it. While a GT30 might spool at 3000rpm (fully) in an S2000, the same turbo in a mack truck will spool far faster due to the amount of air the truck motor pushes. So, if he is running a motorcycle turbo on an MR2, the airflow might be considerably greater. Having said that, I don't know too much detail in the setup, since like I said, I saw the car that one time, so I guess those that are more knowledgable in this spectrum can clarify a bit more.
