I've already driven my 02 wrx wagon over 4,000 miles since the ej207 swap, the miles really pile on fast been my daily driver. I can honestly now answer the original poster question on this thread. Do I regret not having built a 2.5 instead of going with an ej207 ? No i don't, I definitely made the right choice. With the help from people here ( you know who you are that helped me) and the swap process I've learned a great deal. Thank you very much, my swap is a complete success. My bugeye is an absolute pleasure to drive, I look forward to it every day. My next ej207 swap will be when the time comes to replace the engine on my 05 Saab 92x aero, my saabaru.

i finished my swap today. i have the tgv circuit open codes as expected but when i started to drive i got a p0171 lean bank 1. i got the code under load doing about 50mph so im assuming MAF sensor?
BTW i feel a huge difference in the car. i dont have ACVS hooked up as im running the usdm ecu and its amazingly responsive and way more throaty.

That just means one of the air fuel learning trims has become maxed out. You just need to have it tuned.

The differences in the engine harness will depend on the year of the JDM and US motor. Some had the intake temp sensor for example where the US will not. The later models had the blow by sensor connector where the early did not for another example.

So, the Bugeye was never designed for the Spec C oil radiator.
As a result, to route the oil conduits, you have to cut into the headlight bracket, to make room for them.

I'm now switching to JDM HID. I'm hoping that by this time (late 2002), they were starting to have thoughts and doubts that an oil conduit will...one day..pass by and these brackets have room for the conduits.

If not, I will have to make room.

Of course, the S202 did have steel braided oil hoses. But odds that someone has an actual photo of the OEM routing of those hoses and how they cleared behind the headlight are small.

Actually, since the S202 did have the HID, this would seem to indicate that they would have had to make room for the hoses in all the HID lights, otherwise you'd have S202-only headlights..
Then again, maybe those hoses take a different route.

The OEM setup uses hardlines to go through the headlights on the pics I have seen of the spec-c setup. It is much easier to go around the AC condensor and radiator. I just redid mine this past weekend and went this route. Some day I might step up to stainless lines but this works well as an alternatives.

I am running hard lines from the cooler around the AC condenser. From there I will run some small sections of soft line to the motor. Though, like everything I try to do on this car, I'm sure this will fail in some way and leave me stranded by the side of the road. I'm sure of it.

Thanks for the photos and info guys.

Turns out that the brakets of the "new" lights are iffy anyway , so I won't feel bad.

The way I see it, it is more important (and difficult) to get an oil cooler/radiator system that you can trust, than keep the resale value of HID lights.

I thought so much about which way to go, at the time when I decided about oil cooling, I gave myself not just one headache.
Some thoughts:
-steel braided tubes look good, but hide the condition of the tubing underneath. A proper rubber compound tube is more "honest"
-To crimp the AN fittings on the braided tube, I feel I'd have to receive some taining and practice with non-critical applications, before I graduate to the oil radiator. This leaves machine crimped braided hoses, a smaller category of vendors. Mock-up of the route becomes very important.
-In all honesty, the braided tubes should touch...nothing. Except for special guide fittings.
-This is why a conduit riser is safer, it's allowed to touch things and it carefully separates the flex rubber sections, so that they touch nothing.

And I'm sorry, but I could continue writing for a long time about this.

I think that after 2 years I'm entitled to say that I have a reliable system, except I don't have track time with it. I'll keep it unchanged and modify the lights..

So hypothetically, a

JDM v7 207 with 6 spd (wrx swapped)
vs
USDM 04-06 STI


lines up next to each other, both are "stage 2/full exhaust and tune"


Same mods and driver


Which car is going to be faster/pull ahead?

Im just curious as to what car would be faster....

yeah, we all know a supercharged 2.5L N/A is faster.

I think the Jdm would be faster. Should be close though

Hi just swapped a v8 spec C 207 into my 05 Euro wrx. Ran into abit of wiring problems with the Jdm ECU. Apparently it's not the same as the swap into the USDM cars. Car won't start with the Jdm ECU (no CEL) even with both the IA performance bulkhead harness and wiring kits installed. Anyone have access to the Jdm ECU pinout diagram? Much appreciated.

hi it sounds like you've ran into a common problem and that is that the ecu that came with your jdm motor is immobilized. the common solution is to purchase a non immobilized ecu. you well probably notice that when you turn the car on you will not hear the fuel pump prime and the motor well not even attempt to turn over.

another solution is to have your key and immobilizer synced to the new ecu. not sure on the cost of this

What is the code on the top cover of the ECU? If your 05 euro has the Blow by connector, unplug it, It will fault the JDM ecu as it does not use that sensor. Also. If your engine has the charge air temp sensor, Unplug that, The 05 wiring does not route that sensor to the ecu correctly and it will fault the ecu. Some had the sensor and some did not. You state its a spec C, However, Most Spec C's are fake with fake stickers so the import/export people can get more money from you for the engine.

V8's did not have immobilizer, This would be an issue if you had a V9 or later ecu. Showing me what ecu you have will help.
