Rear drum to disc conversion
 

Without a donor car that 5 liug all disc brakes. Would it be possible to just but the parts you would for the v6 version of the 6th Gen accord? And for the front could I just buy new hubs with 5 lugs or is there more I need to consider?

Why are you doing this swap?

For ordering new parts, you want to make sure they fit your current setup. You want to make sure the bearings are the same between your car and the v6, then you'll know the new hub will press into the bearing. It may be easier to find what you need at a u-pull-it junk yard.

Well I ordered a k20c1 crate engine and engine management harness. My plan is to put the engine into my old accord... I know it'll be allot of work but I'm up for the challenge I'm just trying to figure out out how to get disc brakes on all wheels for the extra stopping power

I could just buy the v6 steering knuckle and front end kit?

I checked on rock auto and the bearing have all the exact same dimensions

I'm not sure of everything you'll need for the swap. For the hub, you'd also want to check the CV spline is the same between the vehicles, or your original CV joint won't fit. The rotors on the V6 may be a different diameter or thickness, so your brake caliper may not fit. It will require going through the parts to ensure there are no surprises.

If you swap knuckles, you'd want to make sure they are the same height and the upper and lower control arms are the same between your car and the 4-cylinder. Maybe finding a u-pull-it junkyard will help figure out what could be different for this kind of swap?
