Sir, please step away from the vehicle...

The Ej20K is already a pretty high strung engine and many of the JDM imports were flogged. They are notorious for spinning rod bearings, especially after they get downgraded to US pump gas. Add overheating to the equation and I wouldn't touch that car with a ten foot pole.

Unless you are ready to immediately spent $2500-3000 rebuilding the bottom end on it, that car is a pass. And that's not even considering potential smog/emissions testing issues that you may or may not have to deal with.

Well it's only got about 30k & an aftermarket ecu, the guy daily drove it from a fresh rebuild until now at 30k which took him about 3 years but I figured maybe the water pump but guess not?
