You don't need E85 to make 325WHP.

Proper mods w/proper tune will get you there

Default Rocker cover sealant

It appears there is more than one sealant type on the rocker cover sealing points on this "V9" EJ207 Spec C. I don't see any information about this in any of the manuals I have which only reference Three Bond 1215. I was planning on substituting Permatex Ultra Grey for the Three Bond, but it almost looks like there was some supplemental high temp RTV at certain points. Anybody run across this? I thought maybe it was an attempt to stop leaks, but it is on the inside and outside of rocker cover.

Yup, I ordered a 70mm ID x 3” long and a 73mm ID x 3” long to try out. That’s the best I could find but I’d like to buy a 3 1/2” long section and trim to the proper length. I think 3” long is probably a bit short.

I got a quick response from IA Tuning, they'll have part at my door tomorrow, that's super quick service.
Thank you Stephen.

Anyone with a V8 and up 207 did you use the JDM ac compressor? My 300k mile original ac compressor is done and my V8 207 came with one. Same plug as my car so I am wondering if I can swap it on and that's it? It seems simple but I want to be sure.

No CEL, just no changes to the timing.

Default jdm for daily driven car

Hi all,
I am considering JDM engine option for my 04 WRX. However, I live in tristate area where technical OBD inspections are required.

It seems I would need to marry JDM engine with 04 USDM harness and ECU to be able to go to inspection as JDM ecu will not talk to state computers via OBD port.

Is it a viable option to tune JDM engine with USDM ecu? I know avcs will not work, but how it is for daily drivability/how much do you leave on the plate?

Is there anything that can be done to control avcs with USDM ecu?

What are the common approaches to handle state inspection with JDM engine?

Easy peasy. Do the JDM swap how you normally would need to, then pick up an 02-03 USDM ECU, reflash it with a matching tune to it can run and drive to a point, force all the monitors on and turn off any codes that would pop up. This 100% works and will pass, a bunch of us have an ECU we pass around between NY/NJ peeps.

curious if 04 USDM ecu would work? or there is something special about 02-03 USDM ECU?

my JDM ECU communicates just fine with ODB computers.

the problem i had was i could not get all the readiness monitors to activate on the jdm ecu even with them turned on to ďforce passĒ.

in the end i just swapped in the usdm ecu, did my test and passed, then swapped back the jdm ecu.

In NY, the ECU must match the vehicle vin. You must have the original vehicle ECU or go to the Subaru dealer and have them setup a new ECU to match the vehicle vin.
Running an ej207 on a no avcs usdm ecu is entirely doable but the motor feels lazy, boost is delayed 1,000 rpm.
For your 04 wrx all needed for functional avcs is to add the additional wires and a correct ecu, you will be able to run the motor with both the usdm or jdm ecu.

02-03 just has less emissions codes due to the crap in the car, you can get by with an 04-05

This is 100% false, there is no stored VIN anywhere in the ECU and the inspection machines do not / can not read it. The state gets your VIN from scanning your registration on the window, the only thing the machine can read is the monitors/cycles to determine if the cars emission state is road worthy, nothing more.

My inspection station told me the ecu has to match the vin number on the car.

Thanks for your responses. Another question I have is about tuning.

Basically, if I would need to have JDM ecu to properly run the JDM motor on a daily basis and USDM ecu tuned to run the same JDM motor in safe mode to make a trip to state inspection, what tuning options do I have?

Is that just open source/tactrix? I believe Cobb does not support JDM tuning. Anyone in the Tristate area you could recommend for the dual tuning?

Yeh JDM ECUs need to be open source tuned, which im a fan of. If you have the time and patience to wait on emails, i highly recommend Mike Botti as ive worked on and driven dozens and dozens of cars hes tuned, his work is top notch on top of him being a cool guy. Honestly ive sent plenty of people to just about every tuner within a 2 hour drive of our area and Mikey is the only one i havent had issues with. Theres a few people that do open source stuff locally much cheaper, i can put you in touch with someone if youd like. "Big name" shops will bend you over for wanting a second ECU with a tune for inspections, expect to hear a bill for around $800+ if you call those places up.

Thanks I will talk to Mike to know details.

Also, what do you do to source parts. I assume there's a number of parts that are JDM specific?

Iíd also suggest Stephen Clark from IA Tuning, formerly known as IA Performance. Both my jdm ej207 and ej205 motors run beautifully on open source tunes from IA Tuning.

Mikey is good too, my previous ej207 was tuned by him and also ran perfectly.

Stephen will return a revised map within 24 hours of you sending log files. Youíll go thru the tuning process quickly.

I can also confirm Mike Botti.
Mike does excellent work, responds to e-mails fairly quickly and is easy to talk to one on one.

Mike also works at multiple tuning shops. They bring him in and he does a Road Tuning Day, or at other shops he does a Dyno Tune Day.

Thank you for recommendations.

I also would like to know if I can make JDM engine with WRX 5speed transmission? I know STI tranny would be best, but for now I can only budget for the engine and tune.

Yes, the usdm wrx 5 speed transmission bolts on to the JDM STi motor. You can use the wrx flywheel and clutch. On my ver 8 with the stock vf37 I had to do some grinding to get it to go together. A ver 7 with stock single scroll turbo should require no grinding of the transmission. It is a good idea to get a updated 5 speed clutch. A stage 2 ver 8 will put down a solid 300 fpt at the wheels.
