BTW, this is a normally aspirated EJ20 DOHC engine as used in the JDM Legacy VZ cars (MY89-93). It develops 150 hp at 6800 rpm and 127 lb-ft @ 5200 rpm. It has a Legacy EJ20 Turbo intake manifold, as I could not get the standard manifold with variable trajectory to work (intake length is controlled by the ECU).

Just swap fuel rails? I've got a set of the red injectors that are balanced & blueprinted. The caps & rails are probably different. When I get time I'm going to swap the entire rails.

Q: How does the flow rate of these early (light grey) EJ22 injectors compare to the later (red) EJ22 injectors (280cc, right Josh?)?

Let us know how it turns out.

However, a major oil leak showed itself because there was one bolt missing from the valve cover, which was good, because I feared one of the front cam seals was bad. So put another screw in, everything fine.
Ready for first test drive. Done 200 metres, engine overheating. Drove back, thought thermostat would be stuck, so replaced it. Same problem. Engine temp continuously between 115 and 120 degrees when driving at 1200 rpm. Probably air in the system. Jacked up front of the car, let all water out and filled her up again. Problem solved.
Not much gain in torque, but very smooth and above 5500 rpm a lot of power!!! Too bad rev limiter kicks in at 6700 rpm.
So, all SOHC engines can be converted to JDM DOHC engines, as long as you keep the SOHC engine wiring loom, early EJ22 injectors (light grey) and use the cam and crank sensor that came with your engine. But be aware you cannot fit SOHC intake manifolds on DOHC engines because the bolt patern is different. I run a Legacy DOHC Turbo manifold, but you best use EJ25 DOHC manifolds, then you won't have a problem with throttle body and idle speed bypass valve. But again, use the original wiring loom.
[Edit] You can even see the valve cover bolt missing in the first picture I posted, !!!

EJ20G/H/K/R are DOHC turbo with lower compression ratio;
EJ205/EJ207 are MY99 and after turbo engines.

Yes, some work still to be done, yesterday plug wire #1 fell out, still managed 200 kph though.
