By the way, if I didn't want to go one step colder, would it just be the Denso IK20's? I'm not sure how the numbering system for Densos work, as I've been out of the game for a little while. Do you guys prefer Densos or NGK's? If I didn't want one step colder NGK's it would be the BKR6EIX IIRC right?

The JDM 207 is already one step colder, that 7 series. The EUDM and AUS take the 6 series.
I know this from the EU and AUS workshop manual and from the JDM F.A.S.T. parts catalog.
The JDM coil packs are of a different part number than anything USDM. I didn't check the EU and AUS.

I just bought a set of NGK BKR7E-E (NGK 4776) plugs since they're gaped to 0.032", which is close to what I thought was stock (0.030"). The reason I bought these is because the engine came w/heat range 7 plugs, but I've been running heat range 6 plugs.

My Car runs pretty good w/the BKR6E's that are in there now. No misfires or anything. I gaped them to 0.030" before putting them in.

Should I continue to run the same gap w/the new plugs when I get them in?

Thanks!

bk7eix plugs gapped at 026. If you get plugs that have -11 at the end of the part number, You got the wrong plugs. Those are 44 gap plugs and are for NA motors. Lots of vendors and even catalogs are wrong. Make sure to get plugs that are not -11

From what I'm reading, it's difficult to find the plugs the car is specced with, the PFR7G.
What is available is the iridium version, the BKR7EIX. My info is that these have the right gap.

As far as the gap, I only have info for the PFR6G, from the EUDM workshop manual as 0.7-0.8mm or 0.028"-0.031".

I have not found yet the workshop manual for the JDM version and something tells me that it will be in Japanese, if I find it.

Edit: I guess Clark answered this already, as I was looking at info and typing my answer.

BKR7eix is the right plug for the 207. The PFR is just a platinum plug. The EIX is an iridium. Close the gap down to 026 if the tune or parts are modified.

Clark, .026 is pretty tight. Should I do the same for my V-power coppers when I get them in?

My car has been tuned to run on street gas (93 octane w/a top end target boost of 19 psi) but mechanically unmodified.

Hello, i'm doing a v8 EJ207 swap on my 2004 wrx and having trouble figuring out this vaccum line in the photos. It is part of the purge control solenoid valve, the line that releases the fuel vapors into the intake manifold to be burnt has a "T" in it, off that "T" that vaccum line runs above the intake tube and along the passenger side of the intake manifold as well as parallel to a PCV line, and another line to the turbos pressure control solenoid then was cut not by me this is how I received it.
I have searched everywhere on this site and everywhere else trying to figure this out any help or ideas would be awesome cause i'm fresh out and this is the only thing in my way sadly of having a running car.

I've looked up the part diagrams for the V8 EJ207 JDM. The hose that goes to the valve is always in one piece.
This was aftermarket. Also, if your engine is JDM, this was driver's side. So maybe somebody teed-in for a some kind of gauge.
Also, perhaps some of the car guys in Japan don't know what they're doing, just like everywhere else.
Anyway, I would eliminate that tee and move on.

i agree. Pull the tee off. I have a V7 so not sure if it's different but i don't have a tee nor is there a hose coming off the intake manifold. There's a bolt in it's place.

Glad to help.

JAM 007, Your EJ207 is JDM, right, as opposed to EUDM or AUS?

To check, search the user PDX tuning with keyword bonanza.

The excel spreadsheet should come up and then check the engine number.

Anyone know how to figure out the engine number without the stickers on the block? My timing belt cover has been replaced and the sticker on the back is too faded to read.

Yes it is a JDM EJ207, where were you able to acquire those JDM Subaru service manuals? I purchased an incomplete one on trade bit....so pissed about that.
Thanks again.

Anybody here care to share some Version 8 base maps for stock engine/turbo/exhaust? I'm looking for a safe reliable 91 or 94 octane map for the summa!

thanks

I don't have service manuals, but the parts software for JDM.
I have service manuals for EUDM and AUSDM 207.
I suspect that the JDM EJ207 service manual would be in Japanese, just like the parts software.
I am working to get the service manual for the JDM, but for that a friend will probably have to walk to a store in Japan.
I am sure that 75% of the stuff from the EJ207 EUDM and AUSDM manuals still apply, trouble is you won't know for sure what doesn't.

Also, I'm kinda tired with all the speculation and mistery and want to kinda clarify some stuff, if I can.

Many people used already parts and procedures from the USDM with no trouble and that is fine.
I want to understand what differs in part number and procedure, that's all.

I'm considering doing an EJ207 v8 swap into my 03.

I've been told to avoid the sellers from Canada. What's a good importer within the states that has reasonable pricing?

Also, what's the durability of this motor in stock trim in the 400-450whp range?

I called the vendor about the Ebay listing below and they are shady. They said they paid over 13K just for the motor from Japan and they are losing money on it. He also said, they have a shop setup in Japan just to buy salvage cars from there. When i informed them, that a used EJ207 v8 motors never sold that high. He hung up on me. LOL!

Right your correct, I basically used the USDM STI manual for torque specifications and what not, the only thing that plagued me was that stupid vacuum line and I was just worried cause of the missing purge valve that is on the USDM and not on the JDM motor. But I cut that tee out and saw that it was aftermarket there must of been some type of gauge that used that for a vacuum signal cause there was HKS inscribed on the fitting, oh well its a learning process.

What is available is complete engine part number to engine model number finding.
You still have the engine serial number etched at the top/back of the engine, but I would guess only the dealer could help you ID that.

Last night I found the V9 Spec C owner's manual, in Japanese. The gap specified for the PFR7G is also 0.7-0.8 mm
The Sti also gets the same plugs, it's shown in the same table. The JDM WRX gets PFR6G with the same gap.
The oil reccomendation chart looked similar to the USDM, but there was language (which I did not translate) that sat next to "10W50".

I would have hung up on you too, lol. That price is fairly cheap. I paid 4K for my v7 swap without a transmission last year, from a canadian shop. I am very pleased with it. Looks like it has an aftermarket y-pipe on it too.

Most people want 3200 for a 6 speed, so that is a really good deal.

Be mindful that if you pay via credit card (highly recommended) that your bank may charge you a fee for international use. BOA does.

13k for just the motor? wtf! That is a lot of money.
On the motor that you linked to. I'd make sure the number on the bar code checks out. The after market y-pipe doesn't impress me, nor does the green wire that is all over the place. 6k for both engine and trans is a pretty good deal. sometimes you can find the whole engine and drivetrain for 8k.
I got mine from eagle japan motor and it came in looking like new. I changed the timing belt, water pump, and idler pulley, but didn't need to as they looked like they were in perfect shape. The engine came with a butchered chassis wiring harness and some butchered ac, coolant, and vacuum lines, but I was able to reuse a lot of stuff from my car. The engine harness was in good shape and using pins from the butchered chassis harness, i was able to make my own avcs cable. They gave me a 30 day warranty, but it took me longer than that to get it up and running (dam exhaust!). Oh, shipping was MUCH cheaper from canada having it delivered to my work's commercial truck dock, so keep that in mind. They used the cheapest freight company imaginable, but everything was in good shape, so no complaints. It was a leap of faith, but they were very reputable, plus try building a better motor for less....
