Suby crew: RS swap arrived! WOOT!
-
Well after a bunch of research and learning, I decided on a motor for my RS. It is a swap from a JDM WRX. I picked it up from a guy that planned to build a rally car, but didn't have the time. The rewire/merge of the car is supposed to be a 40 hour job, but I think I have cut that down quite a bit with research on those that have done this swap in the past. The WRX sedans in Japan came with a TD05 16G turbo and have 260hp. I originally planned to do a USDM WRX swap, but this motor came across my eyes and the price was great. Should be a screamer in the RS coupe! Here are some pics! (this guy is pretty excited):
And all should go pretty smooth....except for that box full of wires on the back table
To go with the swap, I plan to pick up some Defi's, 3" turboback, walbro 255, Exedy clutch, and some seals/gaskets to refresh the motor a bit. Looking to start chopping away at the harness next week, and put the car under the knife in the near future.

Looks good Jason, let me know if I can be of assistance on any of this as well (not that you don't have a whole shop full of suby guys...)

I love RS coupes and I love when they have motor swaps. Thats going to be sick my friend

Thanks a lot guys, and thanks for offering to help as well. I am going to tear off all the tape and start labeling each wire tomorrow... Hopefully make some sense of it all. I'll post a few pics as we go with it. Hopefully all goes smooth with minimal drama/unexpected expenses!

sweet swap. EJ207 ftwIt 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...
