Default doing two swaps...nervous

i am in he process of doing an EJ25 longblock swap from an 07 wrx into my 02 wrx. I searched the past threads and understand the issues that come up such as HVAC, AVAC, and the drive by wire that was part of the 07.

I have the ECU, wiring harness, etc. for the 07, but could I bypass alot of the issues of ripping apart my dash and just use the EJ20 harness, ECU, an manifold and keep it drive by cable?

i'm very new to motor swaps and i'm kinda jumping into this head first along with swapping the aforementioned EJ20 into an 01 N/A Forester.

I appreciate any links, answers, or helpful hints you guys may have. Thanks

PS. will the EJ20 mesh well with the foresters OEM 5spd. tranny?

The transmission will fit. You would need engine management of some type.

i'm aware of the engine management. i think i might end up being forced to source a WRX harness and ECU and doing an opensource tune.

your WRX 2.0L into your Forester with harness and all.
Then drop everything from the '07 into your '02 WRX.

Agree with Fuji. Do yourself the legwork up front and swap everything over, in the end it will be much easier though longer to get everything running properly. Two swapped vehicles for the win!

thanks for the input. i understand it is ideally better to do both complete swaps, but from a hypothetical standpoint, would what i mentioned in post 1 work?

To Remove the EJ20 and Install the EJ25 Motor, ECU and Wiring harness you are looking at.
29hrs of labor @$75 per hr is $2175. ( a good chunk of this is separating and soldering wires)

To remove the EJ20 and install the EJ25 with 02WRX manifold, you are looking at 22hrs of labor @$75 per hr is $1650. (requires far less soldering)
(i will install tumbler deletes, turbo inlets, intake, light weight pulley, exhaust kit, clutch and flywheel kit and turbo for free at this point) (its a good time to change out the water pump/oil pump and timing kit if you are buying a used long block / basic timing job is $225labor plus parts but since the motor will be out Ill do it for $175 plus parts)
If you want a open source road tune you are looking at an extra $300

As for the EJ20 into the 01 Forester- its a non turbo so you are going to need the front cross member from a turbo car which will require additional work.
29hrs of labor @75 per hr $2175. If you pay cash Ill do it for $1900

Realistically you are looking at a week to two if I have both cars at the same time, as I have to fit you in between my regular work flow.
