3.0i turbo 90'

if you have the turbo model from 86.5-92 then you have the 7mgte, non turbo is the 7mge. 93 and up turbo is the 2jzgte, non turbo is the 2jzge. the most common overheating problem that i have heard of is blowing the head gasket or just stretching the fire ring out around the coolant passages. both of these would require replacement of the head gasket and all other gaskets from there up. the kit costs around three hundred dollars for all of the gaskets head and up.
