No, a boxer will not fit in a Justy.

Is it possible, to convert from drum brakes to disk[sic] brakes? Anything is possible but there is no appreciable advantage to converting a street Justy to rear dis c brakes. Is your Justy a dedicated race-car? Why exactly are you interested in rear dis c brakes?

Well if you are asking if it is "possible" to convert the rear brakes to discs then you must be new to racing sport. Welcome aboard. As far as 150HP-180HP goes: none of us here (as far as I know) have ever proven to make that kind of power from an EF10/EF12 engine so I cannot say if the transmission will take it but I can offer up this advice: Use the 2WD transmission. If you are racing then you won't need the 4WD anyway and a 2WD transmission will certainly be easier and less expensive to rebuild every time you destroy it with 180HP.
Now if it is rallying you intend to do, that's a different animal than racing.

Being in a unique area with a larger subcompact market than we have here in the States all I can suggest is that you look at other cars with similar size, and suspension in your area. If any of them have disk brakes you may be able to come up with a better idea of how to get them on it.
Like SJ said: Its possible.
Take some pictures throughout the job so we can all drool yeah?

yes you can use front discs from a Justy. I'd use Loyale (front) brake calipers so you still got your handbrake at the rearwheels

I to am interested in this mod and I happen to have an extra set of brakes in my basement. I think the problem is that the splines on the axles are of a different diameter so you need either a custom shim or maybe you could just take the ends off the axles and swap them over.

The old Subie Loyales have got the handbrake at the front wheels The hubs has the same diameter as the axle (+ the same amount of splines ) so the hub will fit right on. I've allready got (almost) everything in stock to swap to rear discs, but I think a need a brake bias adjuster to make it work properly. That's the reason why I didn't swap it already. I might post some pics this evening if you like (+1 GMT)

Alllright! Pic 1 and 2 disc + hub at rear axle Pic 3 Left gen I brake disc Right gen II disc Pic 4 and 5 Loyale front brake caliper with handbrake Pic 6 some Justy parts of mine ;-) ghehe I forgot to mention that you need gen I hubs on gen II axles (Don't no for sure about the axles, I've never had a gen I 4WD) And I think you'll need the 'big' gen II brakediscs, because the Loyale discs are the same size. One of things I'll have to solve is how to mount the caliper. I think it won't be easy to weld on because it's cast iron. I hope this is good information to you guys

Interesting so the hand brake grabs the disc unlike the drum in a disk design.
So the splines on the front gen 1 hubs are the same size as the gen 2 rear hubs?
What would you think about using normal justy discs in the back and then putting a valve in the brake lines for use as a parking brake?

Hmm.. could also be possible but I don't know if that will work with a valve. (and I don't know if that's streetlegal in Holland)

I've heard that Suzuki Swifts were sometimes equipped with rear discs. Not sure about drive axle splines.

Leone / Loyale is the same. Back here in Europe they're called Leone. In the USA they were called Loyale

It's cast steel, therefore you can weld it. If in doubt, you can do a grind test which looking at the parts you would have to do just get the rust off. Take a grinder to the part, if it throws sparks you're good to go for welding.

If you look at post 11 in the thread he refers to the brakes and knuckle as "cast iron" and this is not true. There is a big difference between cast iron and cast steel and even bigger difference when it comes to welding on either type.
