It really doesnt matter what turbo you use, you'll need a tune regardless. The different displacement motor as well as the different injectors mean it NEEDS to be tuned right from the start. The turbo doesn't matter as much.
If you have someone who knows RomRaider around then they should be able to at least set your injectors up and then do some logging to see if the car idles and cruises around light throttle, but I would only drive it to make sure everything is ok and then have it tuned.

I bought these divider trays from Lowes which were really helpful in the past. You drop your nuts/bolts into them with a piece of paper to label. The nice thing about this is things stay in order so you just go in backwards order to put it back together.
The baggies get a little unorganized but they work fine, I've used them as well.

Ahh, found a pic of the tray I used when I tore down my EJ207 (and then decided not to go with the EJ257 instead). One engine, 3 trays...

Yes the air pump is on the 07 STi (and the 06 WRX). I am not sure about 08+ models...
You dont have to remove it, but I did. It involved removing a plastic reservoir under the intake manifold as well as the pump. I had to leave the valve on the car and plugged in (but not routed to anything) because the MAP sensor wiring is related to this so when the air pump valve is unplugged the MAP sensor will not work.
And yes in my experience if you are able to find a complete STi motor that you can be confident in, it often is close enough to the cost of a hybrid that I prefer it. A new STi shortblock, full gasket/seal kit, plus labor to assemble it with your original WRX heads adds up really quick.

I don't believe there is really an easier or more difficult between the years. The only major difference is the 04 does not have the immobilizer so you dont have to make sure to have a matching ecu, immobilizer, and key.

Do you have the immobilizer code that goes with the ECU you want to use? I'm not sure how/if I could help out with this but I have a SSM III... but without the ecu and immobilizer all installed into a car to hook up to and flash I wouldn't be able to do much with it, so I dont know.

for the immobilizer i saw someone take the piece out of their remote then place it in their steering column I think with super glue or something is this a viable alternative?

o which reminds me would i use my original key or the key from the swap when this is all over or does it depend if i swap the column?

If you go 05 and swap front/engine/dash harnesses minimum, you will need to swap out the door harnesses unless you want to graft in the window switches, the plugs are slightly different between 02 and 05. You will have to atleast swap the drivers' door harness out to retain use of the power mirrors. If you re-use the 02 center dash/console, the DCCD sensor box will have clearance issues with the cupholder and mirror switch.
i'm planning to convert the interior as well so those shouldn't be a problem... as for the door cards is the install pretty straight forward?

You could theoretically take the ring off of the lock cylinder or at least the wiring/sensor but I haven't seen that done. Then you could take the chip out and permanently attach it to the steering column.
For me... I wanted the added security of the immobilizer, but I had the luxury of having all of the parts including the complete set of locks from the car. It did take me a while to find the immobilizer code through a friend at Subaru, but I was able to do that just through the VIN.

Ah I forgot to mention the doorcards... yes on the 05+ the design changed. All of the 04 and earlier switches clip right into the 05+ door surrounds just fine, but the issue is the mirror adjustment switch. When you convert to an 05+ center console you lose your spot for the original one, and it gets moved to the drivers side door. So I did all of the 05+ center console stuff and door card stuff complete, again to retain the whole plug and play thing. There is a thread on NASIOC somewhere that I used to determine what parts I could reuse (like the switches themselves), and which parts I had to buy to do the conversion. I believe after you have the door cards and the mirror adjustment switch, its under $100 worth of new parts to convert.

Or if you have the entire STi to pull from and are swapping in all the harnesses from the dash forward, swap out the drivers' door harness, replace the door panel recess mounting handles with the STi's and boom, you're done. Cost of extra supplies: $0. All plug and play! Can be done in an hour or less.

absolutely... and just for reference i believe that both front door harnesses do have to be swapped over to be plug and play with 05+ chassis wiring, but the rears do not. thats just going off memory from over a year ago, but pretty sure thats the deal.

It can with proper tuning to compensate for the extra 25% increase in displacement, you just won't have AVCS.

I might be able to get that. If there is a way to read it from the ECU itself? I have a few vehicles I could connect it to. Would you have an 05/06 laying around you could connect it to for flashing?

yeah you can drive it down to your tuner but just stay out of boost. might want to call your tuner and ask for a map though. that would be your best bet.

i'm planning to buy a AP for 2.5 when i do the swap because i'm swapping everything including the harness... so should i run just the normal map first then maybe i could run the economy mood for it which runs 0 psi?

if your doing the complete swap with all oem sti parts including the ecu and have no other aftermarket parts on it then i don't see why you couldn't drive around in it with a cobb map?

HEY guys!

i was looking at the element tuning write up and they were talking about a "Cam Position Sensor" is this the samething as the Cam Angle Sensor? if so they didn't use the bracket.. they just drilled and tapped it to fit it on. is that an alternative?

and also i see that the sti motor has the feed lines for avcs.. can we just leave this on?

So I am doing the 04 Sti swap into my 02 Wagon.....I decided to go the hard route...

Needless to say...this is a ton of work. I am pretty sure I will have the motor in and running by this weekend. Figuring I started the tear down in the middle of last week that seems pretty good. The biggest pain I am running into is that I have an early model 02 which means the car has the JDM harness...which inturn requires a bit more work including that the rear doors, the rear compartment, and the fuel pump wiring and clips are different. I will have to end up adding about 25 or so wires from my wagon rear section to the STI harness. I was hoping to keep all the old harness complete so I could recoup some of the money dropped into the project. Once I make the changes to the harness I will post some before and after shots to show you all what I am talking about.
Luckily just about everything on the front end matches minus the routing for a couple of the srs sensor wires..that is pretty easy to fix.

Well wish me luck, I will surely need it!!!!

Bombs away!!

We've swapped the fuel tank harness on both complete WRX to STi swaps that we've done... once you swap over EVERYTHING then it all plugs in . Its a bitch though. One of the cars we did was a wagon and that did require some splicing though... but I wasn't the one who did that so I'm not the pro on that subject. WKDerf is the one who did that, so anyone who needs this info specifically can PM him

And if you are doing a complete swap including engine, wiring, ecu then no you dont need a tune right away if you dont have any fuel or intake mods.
If you are doing a STi motor and keeping your original WRX wiring and WRX ECU then you MUST GET TUNED IMMEDIATELY. I highly discourage trying to drive on this setup without at least reflashing with RomRaider to adjust your injector size properly. Remember that your WRX expects to see 440cc injectors and if you do an STi swap you will actually have 550cc injectors... meaning you're going to run ~25% rich... eek.

awesome thanks wrinkleboi that's good to know...

my next question is it best to strip the whole car down to the frame if i'm planning the complete swap... i mean so then i don't need to splice wires or integrate systems it would all be STi then.

i hear alot of trouble with the fuel tanks that's why i ask... also i want to keep this thread at the top

I'm planning to swap the engine, tranny, and all the goodies with them... then the brakes and suspension of coarse.
and then the Interior dash, steering columns, and door cards. I'm just wondering should I swap in everything else with them since i'm using the STi harness would it be better to have everything STi then?

I've got both wiring diagrams and even a list of what needs to go where, its actually really simple looking at it on paper.... I believe its just the physical mass of wiring that scares everyone..... Ill let everyone know how it all goes! Got my motor and stuff in the other day... Just waiting on ecu, hubs, snd axles before I can really start tearing into it! Haven't had a chance to look at the dash yet, how hard is it to get out and get to the wiring?? Thanks again guys! I think in the long run ill be glad that I did the wiring and full conversion...its actually gonna be a lil cheaper because I won't have to get a tune right off and an AP, yada yada......

My wiring diagram says it's under the handbrake. You only need it for the DCCD, not the ECU.
