Default 07 wrx into a 02 sf forester

Okay so a good friend of mine is thinking of eventually swapping pretty much everything from a donor STi into his 07 wrx. That got me thinking, and now Im considering swapping everything from his car to mine. Neither of us can do it so we'll hopefully try and have a shop do work on them both.

Is this a pretty compliant swap including engine, trans, brakes, suspension, dash, etc?
And who else has done it?

Here is the wrx getting the sti swap
wrexy

And here is my sf getting the wrx swap:
Philbert

Cheers, Ben

I've yet to hear of an 07 into a foz, but its very possible to do.

you would be best suited to search subaruforester.org There are 6-8 swap threads that I can think of off the top of my head.

Check it out for sure.

Happy Thanksgiving!

Search on nasioc for JRach. He recently did an 04 sf5 swap and is the man.

Here's the swap I did in my SF5 forester. I used the engine/tranny from a 04' STI, the knuckles/brakes from a 06' STI and the Dash auto HVAC from the 06' STI. Sorry, the pic links are broken... i'll fix them soon enough.

I've done a bunch of different swaps as well as dash conversions and there's a bunch of different ways to go about doing it.

If set on doing the dash conversion you'll want to cut out a few sections of the firewall from the donor vehicle (since your friend is using a donor STI, the firewall is the same and he wont need it). You want to cut out all the sections of firewall where the A/C hardlines and Coolant for the heater core go through, as well as where the rubber boots go through for the wiring.

I've done it that way, as well as cutting the original firewall where needed. In the end I prefer welding in portions of the firewall as it makes fitment easier/better.

If you're using an 06+ wrx as a donor vehicle you'll need the complete key, ecu, transponder unit from the donor car as it will not work without because of the ignition interlock security feature.

Mechanically the SF5 swap is IDENTICAL to a 98-01 impreza (93-97 had a few changes in the firewall where the steering column goes through). It's actually easier than a impreza as the rear tophats for the suspension are the same as the 02+ subaru impreza

Thank you guys so much for the input!
A little info on my sf
it has 145,000 miles, basically stock 4eat
wrx has 70,000 miles with the full Cobb stage II package

Thinking about painting the car a sandy flat tan or a deep flat gunmetal
I wish I was able to do this all myself but I am no where near knowledgeable nor have the spare time to do something like this myself.

Any additional information and tips will be greatly appreciated

Cheers, Ben

After talking with my friend Will with the wrx, he suggested that we try to do the swap ourselves. He has the perfect garage and tools for it but I dont know the first thing about doing any type of project that big and I dont believe he does either. My question here is can we figure it out and do it ourselves or should we just have a shop do it? I was thinking that the wiring would be the biggest issue here, so we could find a reputable shop to do that.

Also Will is thinking of doing a rhd sti swap in his wrx, is it pretty straightforward as long as you have the conversion?

Any tips will help
Cheers, Ben

MY SWAP WAS LISTED!! lol ..

as for your last statement.. depends.. are you going to use the 07 dash in your car? if your freind has a complete donor car.. then you both can do it on your own reletively easier.. id strip the donor first.. and like JRach said use the firewall.. i didnt use the firewall and can hear my loud ass engine from inside and air leaks in .. on a long hot day it can be killer.. if the donor has minimal front end damage that be awesome as you can use the cooling on your sf and AC lines.. I created a hybrid ac using my sf and donor lines.. works .. your freinds wrx will be a breeze as long as you have a complete donor.. youll basically strip both cars and swap in all wiring and dash from donor.. the sf.. well its mostly easy.. just the doors are a pain to wire kinda... other then that the rest of the wiring can be used.. all the way to the tail lamps.. just cut and extend if need be.. or merge under passenger seat.. just take your time and label and store parts correctly.. wont be a 1-7 day job without mechanical experience.. but as long as you have fun and take your time it should come together ok


BTW: JRach.. i love your ride.. probably more then I like angry's .. the paint is awesome.. I always debate weither I should sell my forester and I usually run into a pic of yours and reminds me of what I still want to accomplish.. my funds are lacking tho lol

Thanks for the info guys!
Im excited to start this, I have been thinking about painting the car flat tan. And probably a matte grey or black deep wheel. Just trying to figure out the right ones.

I would like to end up with around 280 whp once this is all done.

(sorry posting under the shop account)

When I did all my swaps I swapped the entire abs pump and hard lines over to the new vehicle.
