Ok. I just purchased a 2003 IS300 5 speed with a 2JZGTE twin turbo swap for a weekend fun car. When the motor was swapped, the shop bypassed the heater (weekend car, no big deal). Well. long story short. My dad and I were on our way home with this new toy when a tree fell on the hood of my daily driver and totaled it. Winter is coming and I have no heat. So... my question is what hoses do I need to hook the heater up (stock or custom) or is it not even possible? Any help would be greatly appreciated.

Buy a 3 day subscription to Toyota TIS.com and look up the cooling flowcharts for a Supra and an IS

on an IS300, there is a coolant port at the top middle of the back of the head, and a metal coolant line on the passenger side of the motor, near the firewall... Assuming it was bypassed properly, these are most likely attached to one another... In this same area on the firewall, you should see two 5/8" or so metal lines sticking out - this is your heater core... essentially each of those lines needs to connect to one of the lines off the motor - it really doesn't matter which is which, they just have to be hooked up...
