The first EJ20 engine with turbocharger is EJ20G. This engine has DOHC cylinder heads and oil piston spray jets for cooling, low compression ratio pistons (8:1) and fuel nozzles 380cc. Bucket-style HLA EJ20G engines have lightweight valves and simple air-cooled intercooler.
Is the EJ20 turbo a good engine?
In their turn, naturally aspirated EJ20 motors are more durable and trustworthy. They can run 150,000 miles (250,000 kilometers) and even more.
Can you turbo an EJ25?
The truth is the high compression on the EJ25 motor is what really makes it a bad idea to turbo. You seriously hurt the reliability of the motor after it goes turbo… no mater how little boost you run.
Can you turbo a non turbo engine?
Yes, though there are a lot of things to consider. First, the turbo takes up a lot of room, and you have to get it connected to both exhaust and intake flows, and you will need room for an intercooler (and a place to put the heat exchanger, whether you are doing air-to-water or air-to-air) as well.
Why do you need a turbocharger in an EJ20?

What kind of tuning should I do on my EJ20?
Most air intake manifolds are begging for aftermarket tuning parts, although a few makers provide reasonably well designed air intake manifolds. Big valve conversions on the EJ20, getting port work and head flowing will also boost bhp and torque, & importantly will raise potential for a greater bhp and torque increase on other upgrades.
