Do you have shielded wires and pins?

If you need step by step I would just get the IA kit, it has good instructions

Dont waste your time, they are a pain in the ass to pull out and you might **** up the connector, its usually easier to just cut and solder the wires.

You only have to add wires so if you have the pins there is no need to remove anything from the connectors unless you are trying to repurpose the TGV wires

Swp

Default ?

I am doing the same swap as him, my question is what harness do I get? Iaperformance has a bulkhead and a engine harness kit for this swap? I am not sure which one I need? I also haven't decided what I want to do. I am either going to run the wrx ecu with a Cobb accessport and no avcs or the full jdm engine with the jdm engine harness and ecu. I don't know what kind of power loss I will take by not running the avcs? Let me know what you guys have done?

AVCS makes the JDM motor and gives it all its low end torque, they really feel weak without it. Run the JDM ECU and get tuned by someone who actually knows how to tune the ej207, if you tune the 207 like a WRX 205 you will be missing out on some decent power. The engine takes more timing than people expect, around 5-10 more than you would on a 205

IA performances AVCS harness is all you need http://www.iaperformance.com/product...oducts_id=2580, it drops in and done, takes ~30 min

you only need the motor harness if you did not get the JDM engine harness.

I'm in the same boat, I have an 02 wrx, would i just need the above harness since the 02 already has the bulkhead harness? I also plan on using the usdm ecu.

If you are using the USDM ECU you do not need the ACVS harness since the USDM ecu does not support AVCS.

Running the EJ207 with a USDM ECU means no AVCS, and all the low end toruqe benefit is GONE. I suppose it's easier since you don't need to re-wire anything... but you should drive an AVCS car before you decide not to use AVCS. It makes a huge difference in drivability... enormous.

But then I'd have to get the USDM ecu tuned just to drive it to the inspection site, I was mainly trying to avoid that hassle.

Also, does anyone know if 205 cams will fit in the 207 without regrinding/machining? This is for my backup plan...Couldn't find any posts on this...

It will run on the USDM ECU with no real problems, wont be perfect without a tune but it will work. There is no reason to swap cams.
