Help me build the best ke36

Hey i might sound like a dumbarse but i am just wondering what is the biggest motor you can drop in a ke36 without moving or touching the fire wall. I am a fan of supras so i was thinking somthing like a 1GGTE i have heard of people drop these in if you have any info on this it would be greatly appreciated. Where did the intercooler go howmuch room where was the fan what was it like to drive i understand it would be very nose heavy is there any way of changing this and why arn't cars like supras or skylines nose heavy. Would it be possiable to drop a 1jzgte in a ke36 how much heavier is that motor. If you got larger stiffer suspension would it improve handling. I just really want a ke36 with a 6 in it that has a bit of power and a nice car to drive.
