Hey i bought a forester that had a full JDM v7 STI swap done. The previous owner's both claim it has a spec c engine, but both model stickers are removed (suspicious af)

The engine has

S20C 701 near ps pump

087100 on each side of the split on block where transmission bolts up

B576349 stamped above the starter housing

Transmission (not a guarantee match to engine) is Ty856wb1ca, according to some sources it matches 2001 STI type RA

Any help identify this?

Take a look at first page, in V7 there was a spec c and a RA before it.
First see which turbo it has, in case it's still stock.
Basically, if you look at the table, ask yourself, what makes a V7 a Spec C, the major components are there, you'll rsearch the part number differences between crank cams and even heads.
This thread is all about "do your own research", the tools are here on first page..

Now, something that was not researched that much is which V7 got the transmission oil radiator. This was for a V7 the combo unit, where the top is coolant and the bottom is oil. See if your transmission has the oil pick up and return points, maybe sealed off..

Fantastic and really well put together.

I will be doing a EJ207 V9 in a MY08+ STI, I have been searching for other build threads/experiences with the process and anything i should be aware of with the newer chassis... A cup of tea and a lot of reading inbound.

Wish me luck!

Stickers do not identify the engine.... the one that was on my car was about to fall off and I just took it off.

Thanks for the reply. The issue is that at some point someone changed the turbo and a few other components on the engine that could help identify it.

The other unfortunate thing is that I have no idea where all these 'special feature" are located. With the lack of detailed pictures on this forum and the massive variety between years/models/submodels I call in for some help.

If it's the original oil cap on the engine you can tell what year it is underneath it. Serial numbers should tell you everything about it.

Is an adapter required for the tactrix cable when using the JDM ej207 ecu?

Yeh thats an early GD 2001 RA non-dccd trans. At this point in time any of those parts could have been changed, but the Spec-C model wasnt released until 02 in japan. S20C are standard blocks for both years, both the RA and Spec-C should have had VF30's on em. I feel when selling a motor or car with a swap, people throw out "Spec-C" and "Type-RA" monikers all the time to spiff it up to sell.

As a heads-up to anyone attempting what I described above, unfortunately the banjo bolt with the -4AN male will not fit in place with an OEM turbo. The EJ204 AVCS feed is much less useful than originally expected.

what do you mean? I run that metal line on my D25 head, its feeding the AVCS from the top of the head, and the turbo is fed from the back of the head

The metal line that is pictured above was from the EJ204 which was a non-turbo AVCS motor - the AVCS is fed from the rear of the head (not the top) and I attempted to change the rear filter feed bolt to a -4AN banjo fitting (shown in photo). The problem was that with the OEM banjo feed hard line in place, the bolt is too long and the -4AN nipple contacts the turbine housing on VF39 + VF53 turbos (so basically any VF-series single- or twin-scroll).

If you are feeding the AVCS from the top of the head (as Subaru transitioned to in 2007-ish), you might be fine given you don't have the metal banjo fitting on the rear.

Kleenex makes tissue papers that people commonly refer to as a "kleenex". This is called name brand/product association. Modine is a company that makes heat exchangers. I'm pretty sure that I'm not alone when I say that I have never once heard of a radiator or a heat exchanger, or any product that Modine (or any other manufacturer for that matter) makes referred to as a "modine", in the way that people refer to a tissue paper as a "kleenex".

Go ahead, look at their website. If you can show me a product that they call a "modine" anywhere on there, I will humbly apologize for my post. Otherwise, consider yourself educated on this matter.

You know what? use proper terminology in this thread.

I think language and width of vocabulary is important and I think that one mission of an engineer is to promote the use of technical vocabulary.
Technical terminology exists because it allows singling out devices and assemblies, so that other engineers know without a doubt what you're describing, with the use of one or two words.

Years ago, I got a temp gig as technical translator. I had to do this with headset, not hearing my own voice, speaking almost at the same time as the conference host. This worked well until one of my customers interrupted, because although he didn't speak the language of the host, both were engineers and he knew the technical term that was being translated. As an engineer, you had to and I dropped the ball there.

Oh and those that go to the Japanese translation of an item, don't go to the ad-literam translation. Once the ad-literam translation is complete, for a manual or the name of a part, a staff engineer reviews it and converts to the English engineering terminology.
There is no linguist way to circumvent the Mechanical Engineering out of the Automotive Manufacturing sector.

Otherwise kleenex your xerox with your nikes out of this ...

LOL, the v7-9 are known jargons, the official version codes most don't know.

Once again, mrsaturn, the level of detail at the beginning of this thread regarding versions, as well as their successful use for more than a decade, qualifies those.

Forcing people to change a system that they use (versions), for the sake of abiding to a system that designates cars(GDB ...), when we're dealing with engines only AND we're using the factory system in designating those engines would have been a petty short minded decision, one that you apparently keep bringing back at every possible occasion.
Maybe because you know this system and nobody else does?

On the contrary, the system of GDB-A, B, etc. designations was defined by Subaru and used throughout the parts database. The only reason you do not know the system is you are willfully ignorant to it.

The factory never used the version system on motor designation, you are completely and utterly wrong in that sense. When I import parts, if I ever referred to the part I needed from a motor using a version code, it would confuse the hell out of the Japanese supplier. The factory GDB motor coding is just '207'. This in and of itself is incomplete data, so let me break it down further to show why your entire list of page 1 data in this thread is misleading and perpetuating bad information.

I'll repeat this to make my point very clear - this foundation of this entire thread is misleading people on how to properly identify and spec. out EJ207 replacement parts.

The Subaru parts system hierarchy is as follows (it has been this way since the 80's, and is still in use today):

1. Model = "IMPREZA" (this is the top level of the database)

2. Model Code = "GDBA" through "GDBG" (among many others such as GDAx, GD9x, GCxx, and so on; I selected GDBx to simply limit the scope of this explanation)

Model Code is literally the second level of organization within the system. Let's drill down further and take GDBG as an example:

3. Trim Code (usually ties to 'Grade' on the performance models) = -4LH, -4KH, -4FH, -4EH are the four available 'Grade' options, corresponding to RAR, STIA, RASC, and STI, respectively.

Within these, each has the following defined:

Sales region = Japan
Engine = 207
Drivetrain = 4W
Transmission = 6MT
Grade = (see above)
Body = S
Suspension = N/S

On GDA models, you may see trim code designate two Grade 'WRX' models, with one of them having a 5MT and the other a 4AT transmission. My point here is that trim code does NOT link directly to only 'Grade'... it just often does in the STI and RASC grade models.

Now here's where I'll show how asinine it is to grasp onto this version code system. By your system, you would call all motor parts in the GDBG 'version 9' parts... so give me the v9 oil supply pipe for the turbo. Oh wait... did you mean 15192AA480 or 15192AA470? These parts are not interchangeable, so you can do a few things here:

1. Order the wrong 'v9' part, bend it to fit, and cry when you burn up the CHRA from causing a hairline fracture on the brazed oil fitting.

2. Order both 'v9' parts, throw the wrong one in the trash and piss away 50 USD on a part you can't return.

3. Use Subaru's well-defined parts system to buy the right part in the first place.

You told people to use proper terminology but you get downright militant when I suggested you do the same. I could care less if you use it or not, but you're being painfully hypocritical for telling people to use correct terminology and refusing to yourself.

The system of V7-9 was invented by hobbyists as a carryover from the GC-era V1-6, which, technically speaking, was also slang/jargon created by hobbyists. The biggest difference was that GC-era stuff had more things that did not change between model years, therefore the version system worked pretty well.

The V7-9 system only works at face value when you don't really care what you're buying. For instance, if you just want a GD-era EJ207 with forged internals and a single-scroll turbo, you can buy a V7. Want a newer single AVCS twin-scroll EJ207? V9 will get you in the door with an second-hand dealer, for sure.

What if you want to buy replacement parts and formulate a spare list for this used motor you bought? This is where the version system is pure garbage... it will only cause you to piss money away on parts that don't fit and why creating all the lists like you've done on page 1 is completely pointless. When I import a part for someone, you can be damn sure it's the correct part the first time.

So do you want me to qualify v7-9 as a valid system? Absolutely. People use it. It is a system. A system marginally more useful that telling someone your car is a "Stage x" WRX, but a system regardless.

I will continue to use the proper terminology; you continue to tell people to use the proper terminology while grasping onto your broken, inferior system as if you'd created it yourself and had something to be proud of here.
