tuning

I drove a 1996 Nissan Maxima...then bought my sc300

Hey everybody i recently bought a 1992 SC300.. i am doing the soarer swap....1jz 5 spd....Now i have a question does anybody know how to tell if the 1jz i am buying came out of a soarer. I ask because i have been told that depending on that i might have to do some modifications to the engine.
