i would suggest swaping out the motor for either the JDM 1JZ-GTTE from the soarer, or the 2JZ-GTTE from the supra. both motors will go in with little trouble. if a motor swap is out of the question, i would reccomend looking for performance parts for a non-turbo supra instead of an sc300. you will find more parts for the supra because it is much more popular. glad i could help.
