Sadev AWD system!

I can't wait to get this started! Guess I need to figure out some sort of ecu for the awd also. Does anyone know anyything about doing that? I guess it could just be set up as a mechanical full time awd that just keeps pumping a consistant division of power instead of the smart systems like Mitsubishi and Subaru use....soooo much technical jargon to wade through!

not sure how the subaru system works, but you can probably set up the subaru diff controllers as stand alone, although you may need to send them a signal from the sonic's abs sensors. you may want to start a thread over on NASIOC.

The only thing feasible from any WRX that you could use, is the rear diff, axles, hubs, and struts.
The Subie is a longitudinal AWD setup where the engine and transaxle are pointed north south in the chassis. Additionally, it doesn't have a separate front diff or a transfer case. The front and center diffs are incorporated in the transaxle assembly.
A better candidate would actually be an EVO since it is a transverse layout similar to the Sonic.

^ and a better awd system of you can get all of the electronics to work properly. However they are much less readily available

I was actually just looking at that and was coming here to bring it up lol. I want to do a complicated build like that, but I think I'm going to put the time and energy into getting it engineered and laid out correctly before I trust my life to it at high speeds lmao. I may hit up GM and see whose ass I need to kiss to get the awd from the Encore sent to me. Its not the best, but with some tuning it can be more than enough for circuit and rally sprints, plus dependable enough to drive daily when I want.
The SC90-20/150 is a transmission for longitudinal drivelines, are you planning on turning the engine 90°? The ST90-18 would be the only usable box from Sadev.
Don't forget the most important part: money. JUST the gearbox mentioned above will run between $15,000-20,000.
After that all you need to do is
1. Make a bellhousing/adapter plate
2. Figure out a new flywheel/clutch for the new TO bearing height/starter position
3. Possibly relocate the engine to alleviate any frame interference from the longer transaxle
4. Have new axles or inboard CV adapters made for the front
5. Make custom intermediate driveshaft + adapter to transaxle + adapter to rear diff for full time 4WD
5. Alternate for center diff: Replace rear output on ST90-18 with Mitsubishi EVO center diff section. Would be a long shot on being able to be adapted to the output tube, and would mean an additional adapter CV, as the driver's side axle would be whatever Sadek uses, and the passenger side output would be Mitsu. At that point obviously you'd be better off just using the whole EVO transmission.
Then all that's left is driveline routing and rear end.
I couldn't see Sadev offering a complete package for anything less that $30,000 IF they could sell quite a few packages. However at that price they would be lucky to sell 1 or 2. I think it would be amazing if Sadev came back at anything less than $50,000 for what would basically be a one-off.

Haha, I was browsing through the thread and about to reply with "Why not just buy a AWD vehicle for half what it will end up costing in time/money" when I came across this post.
I know this is 'fun' as enthusiast hobby stuff, but at some point common sense still has to be applied.
In this case a simple question can be asked and answered:
"Do the ends justify the means?"
Answer: Hell no.

Subaru?

That's what it sounds like to me. Turbo plus awd plus tons of mods = wrx from my understanding.

I was honestly looking into this as a possible project to do over time. While it wouldn't take me long to get up the 30k (minimum), it isn't something that I was really planning on knocking out anytime soon. Just exhausting all frontiers before I have to settle on what everyone else has already done.
And I came into my first Sonic from a 2006 STi. Had it for 6 years until a deer decided to cross the track in Michigan. In case you were wondering...hitting a deer at 90mph is not exactly a pretty sight. For either the deer or the car.
Anyways! I wasn't aiming at really getting a production kit made. I wanted a one off that would be a badass setup and maybe inspire others here to take their car to the next level.

I'm sure I'm sounding like a dick head but in my opinion there isn't a next level for the sonic besides a tune, intake, exhaust and maybe coilovers...even that seems a lot to spend on this kind of car...unless they want to bring us the OPC version of this platform from over seas...but even then...if the RS is 23k...how much would that be? There are a lot of cars that I would start looking at for 23-27k before a sonic. LT 1.4t with a tune however is one of the best deals out there for a fun annoying ( to other people ) car for 16-17k. The other problem with the Sonic is resale. My car stickers for $17700 and is worth about 11-12k on trade right now. You wouldn't see that in other more stable brands.
