OK, a few issue.

The 2nd gen xB and the bB share absolutely no parts. They are not the same vehicle. The xB is called a Toyota Corolla Rumion in Japan.

There is no frame on an xB, it is a unibody vehicle. I figure you know this but switching to the Matrix underpinnings would be a massive undertaking as you can bet that nothing would line up and you would have to fabricate most of the swap.

Now as for parts from the Matrix you can use, I would take the trans and rear driveshaft assembly as they will bolt up to your engine fine since both the Matrix AWD and xB run the 2AZ-FE engine. I wouldn't bother with the engine except as a spare to build up if you want to boost later on.

As for the rear suspension and underpinnings I would spend the money to get the driveshaft tunnel, rear floor pan, and rear suspension and axles from a JDM Rumion shipped over. Yes, it'll be expensive but probably about the same , or maybe even less than trying to fabricate the Matrix parts into a car they weren't designed for. Basically doing a "body swap" with the parts that will actually line up correctly and ease the fabrication substantially. You don't need to have the whole car shipped over as you don't need the engine or any of the other body parts so it'll cost less than bring over a whole vehicle. If you check on some of the FB xB pages there are guys who can help you get these shipped over as they bring shipping containers of parts over.

Oh yeah, you'll probably want to have the interior carpet shipped over as well since the floor pan will be different. The rear seats bolt in the same on all versions of the xB/Rumion from what I remember so you won't need that.

Here's a link to a Japanese online parts site I use that really helps in seeing the stock parts, http://auto-kat.com/index.php?route=saleepc/toyota/groups&region=JAP&modification=138745

Use it against a USDM site to see what the differences are between the vehicles so you know exactly what you need. I would also compare the Matrix parts pages against the xB just to see how different they are. I may be wrong and they might be an easy fit since they are built from the same base platform, but I wouldn't count on it.

Oh and one other thing to keep in mind. Only the Matrix XRS has the same wheel bolt pattern as the xB, 5x114.3. So if this donor is not an XRS, which I don't think had AWD, then it has a 5x100 bolt pattern for the rear wheels so you would need to do a hub conversion as well. While the Rumion does have a 5x114.3 bolt pattern.

If you are game to do it I say go for it. Just take your time to plan everything out thoroughly, because no matter how much work you think it will be it'll end up being at least 50% more. lol

PS, for larger brakes you can swap the front rotors and caliper from a 2011-up tC right onto the 2nd gen xB. You get slightly larger pads and the rotors are thicker and .75" larger in diameter. I did the swap on mine a few years ago and it works great. You can usually find take off calipers on eBay or at your local wrecking yard for $100 or so.

All bB 4x4s came with the 1500cc 1NZ, the 1.3 was an option in the NCP30/31 but the long stroke, high geared 1500 is the standard fit in NCP35. I never heard tell of a 4x4 with a 1300 and in the later 2nd generation bB, 2005 on, the only 1400 option was a diesel. The 1500 isn't much liked in the trade but it certainly has a place in the 4x4, where its torque, peaking as it does some 800rpm earlier than the 1300, is more useful than the ability to accelerate from rest to 80mph in 1st and 2nd gears, leaving the sales reps in their new Ford Focus wondering what just happened! (for a time they do, then they catch up and pass you in a cloud of black smoke before vanishing into the distance).

JPB, problem here is that we are talking US market xB. We never got the 2nd gen equivalent of the bB as our xB. The 2nd gen xB for the US is the same vehicle as the Japanese market Toyota Corolla Rumion and the Australian market as a Toyota Rukus. The only engine oprion for the 4WD model was the 1.8L 2ZR-FAE engine. We were never offered the 4WD drive train here in the US and all of our cars came with the 2.4L 2AZ-FE engine.
