Suby crew: RS swap arrived! WOOT!

It is a nice swap, but the EJ207 it is not, I'd say it's a version 2/4 as it has no coilpacks. That puts it in the many years of ej20g high revving 7500, and all sorts of tried and true power/tuning options.It's a great choice, I hope everything goes well. I would love to come take a look or lend a hand if you ever feel like letting me.
This is correct. It is a EJ20G with the Z4 ECU. Basically the EJ20Gs came in pretty much every WRX/STi from early 90's to I believe late 90's/early 00's. They rev out to 8K+, however start losing power around the 7500-7800 range. The big difference between all the EJ20G's was the td04 turbo in the wrx wagons, and the td05's in the WRX/STi's. The biggest difference other than turbo is how aggressive the factory ecu is tuned. The Z4 is about as aggressive as they come, with the exception of some of the RA STi's and a few other randoms. Internally in the motors, there is very little fluctuation, with forged items making the differences.
Colin, you are more than welcome to come take a look at it and help...I don't know what all there will be to help with, but an extra hand is welcome. Wiring is going to be the headache, and that is something I will do on my own....Just because I want to know that I have nobody to blame when I turn the key and nothing happens (knocks on wood)...

very, very nice... i'm jealous... so what doing with old engine??
Haven't decided yet... There isn't a huge market for the DOHC RS motors, and some of the items off my RS motor are interchangeable with the EJ20G...So I may just tear it down and sell a few parts and keep the others for backups (my RS only has 52k original miles, so the interchangeable parts should be good replacements)amicheze wrote:
Nice! Any pics of the car?
One of very few ever Brilliant Red RS's (approx 1 of ~200 Brilliant Red Coupes) -
I'll probably stop in on tue then,
To be honest with you, call up ECS or Garage tuning and pay the $1000 dollars for a plug and play harness. Their finished products are Beautiful, and their turn around is ~2 weeks. Seriouisly. It seems like alot of money, but once you get started there's no turning back.

This has crossed my mind a thousand times. Maybe 2 thousand, but I am confident that with our collective subaru knowledge we can do it. I have received all kinds of wiring route information, ecu pinouts for both motors, and a bunch of tips from here and there (seriously I have a binder of about 50 pages of information directly relating to the EJ20G merge, not an afternoon's worth of reading). I have lived on NASIOC/RS25.com for the past 2 months researching. I know ECS and GT do GREAT work, and I know the failure rate is high for these swaps. I want something I can say I did myself, and tell other customers that we have done one IN HOUSE with the merge ourselves. To be a shop that specializes in Subaru modification, and send out the wiring for someone else to do it (and pay $1000), would be mashing our face in the mud.
I will be here tonight cutting away all the tape and labeling if you want to come by. Tomorrow night I won't have time to work on it...

Very Nice-ah! I got nothing these guys haven't said already, sweet project.

Cool its not a Honda, I like that car. Its not my color but then again its not my car either, I once had a customer come into NAPA with one to get brakes and I asked him how much they weigh, boy was I shocked to find out it weighs almost as much as my Cougar, but AWD FTW.

Its gunna be sick!

In the Subaru community, the Brilliant Red RS coupes are a pretty big deal.
I don't know who stopped into your shop, but the RS coupe weighs in at 2825 lbs...I don't think your cougar is that skinny...amirite?

car should really move once you get it done!
are you sticking with the stock trans?

yeah, they have been proven to be stronger than the USDM 02-03 WRX trannys (not saying much), but the swap will consume all my money for now, and after the tranny goes, it will be time for something cool...

PROGRESS:
Well here is the harness we started with:
Here it is after unnecessary (we hope haha) wiring is removed:
Here is the wiring that was removed (eek):
This is a super start, and my hours upon hours of research really paid off (along with the help of Shane)... I am hoping to continue moving forward with progress and get this thing under the knife in the near future.
WOOT!

Looks like a fun project, good to see you getting your hands dirty Jason

K, and i do have some questions, I am a complete noob to subies.
Does the stock ECU have options, can you do much of anything with it??
What is the item Colin is talking about? is it just a harness to connect the ECU/engine or some sort of tunable ECU and harness?
Why no standalone of some sort right away??
-
Depending on the year of ECU he is using, there is RomRaider (aka enginuity), ecuflash, etc... available for tuning w/ just an OBDII to USB cable. http://forums.openecu.org/index.php (not that Jason doesn't know about this site, I know he does...others may find it interesting however)

I'm guessing it's just modifying the harness to be able to swap the motor in (stock ecu for that particular engine)... and what Colin was talking about is a pre-made harness, kinda like Rywire makes for Hondas? At least that's how I understand it... I dont really think he'd need a standalone, like swapping a B series into a Civic, if the engine and everything is pretty much stock, there would be no need...
