Yes 0.26. It sounds similar to the issue I had. Ended up being spark blowout caused by a bad coil. I would try new coils.

Thanks man.. I rechecked the ones in the engine bay... will check the one on the ECU.

Here's a good article I found on the swap, especially people with wiring question:

Yep, gonna pull a known working coil pack from another wrx and start the guess/check process. I may as well take a look at the plugs--should I bother with gapping the iridium plugs?

Yes gap them to .026 that may be your issue if not then it may be a coil. If not its not ignition related

Hopefully one of those two solutions will fix it. Otherwise I'm pretty well stumped.

What upper heater core hose are you all using(those of you who are swapped into an 02-07 wrx). The stock wrx hose most definitely doesn't fit so, just made something custom or what?
I'm curious about this as well? Is the hose just too short or in which way does it not fit?
To the guy that said he got one at autozone, did you just take the old one in with you and have them give you a longer hose the same size?

Here's latest log I just pulled. You guys take a look and tell me what you think (not sure if I logged ALL necessary parameters). There were some "Knock correction advance" activity in lower RPMs... should I be concerned? Thanks again as always!

Yes. My shell didnt have any heater core hoses so I took the cut peice off the JDM motor and got that same size one.

Feedback and Fineline are the ones you want to be concerned with.

Hey quick question. The lower radiator hose connects to a fitting with 2 smaller black hoses on them w/ clamps. What are those hoses called? Anybody have a diagram on it? V8 ej207

Yeah it's the elbow bend hose.. Best replacement? Get a look alike hose from autozone/home depot or are there any other brands out there for a better quality than this flimsy rubber?

I use this for diagrams:

http://opposedforces.com/parts/impreza/en_g11/type_23/

It's the RHD Europe 2.0L STi. Not sure what differences there are between this and the JDM, but I figured it's closer than the USDM...

What spark plugs are you guys getting?
Can't find an equivalency list for the pfr7g

Well the coil packs solved my stuttering problem

I'm tuning for e85 and my boost seems somewhat low. Running a completely stock setup (vf37 ver 8 ej207) with 850 cc injectors and Grimmspeed ebcs

My boost is at 13 psi at 6400 rpm (where I cut off the pull). I'm reaching full boost (19 psi) around 3900 and then it tapers off around 5200 rpm. My boost doesn't seem to increase anymore in the higher rpms by increasing the wastegate. I guess there might be a leak, but I'd think I would have trouble building up to 19 psi if that were the case. Any ideas?

That makes sense, in order to clear all the drivers in the computer for the inspection I was sent out to drive my car. I had no choice, drove the car 45 miles on the usdm ecu. Came back, everything cleared, got my inspection sticker, happy. Car ran fine keeping off boost under 60 mph. I then swapped to the Jdm ecu and drove home, 20 miles away from my friend's inspection shop. When I got home I noticed that the engine seemed to get really hot and sounded like it was knocking from just bleeping the throttle lightly, not happy. No such condition with the usdm ecu, engine seemed to work healthier. I have a long drive to EFI Logics, thinking of swapping the usdm ecu back on for that drive. At that point I'll have a walbro fuel pump, aftermarket catback and Perrin turbo inlet installed. Not feeling confident driving the car on the Jdm ecu from here on, specially once I install mods. I'm going to pull a rom and contact you, perhaps you could tweak a safe map for me. I don't have wide band yet so, no logging for now. Avcs wires you made me work well, thank you.

Cool, ordered a set, are you gaping those plugs or are they properly gapped out of the box?
Thank you sir.

What I was trying to tell you and white too is that your car will run rich, with the USDM.
While in closed loop this is compensated to a degree. In open loop not really.
Then the MAF, air table was wrong too.
With this combo, the car could have run some high exhaust temperatures, it's almost impossible to predict. This is probably the heat you noticed.

I wanted to go into more details yesterday, but it's upto you to make the right decisions for your car, you have the info now...

I'll add this:
We know that rich running carburetor cars can get fuel into the oil. Well... I have personally experienced in my personal old Mercedes Bosch K Jetronic fuel injected, it dumping fuel into the oil, as I was trying to adjust the mechanical fuel distributor pump.
While this was a more extreme situation, small amounts of fuel could thin the oil.
This was before my current old diesel Mercedes.

Running very rich, cranking rich, etc, can have effects.

I was having issues with my knocklite detecting knock in upper rpm's . Pulled the plugs and they were gapped to around .030 so I installed new stock heat range ngk iridium plugs with the gap around .027 and no more knocklite flashes. I also cleaned my maf at the same time
