Will it bolt on? Probably. Will it line up with everything correctly and look right? No. Coupe/conv hood/fenders/lights/bumper are different from sedan/wagon. M3 may be a direct interchange with the other coupe/conv, but I'm not sure on that.

 

So, id have to have the hood custom fitted then? If it doesnt line up does that mean i cant close my hood up?

 

Just use the search function my man OEM M3 PARTS ON NON-M - modding guide

 

Sudan, as in the country? LOL I think you mean sedan, right?

Anyway, your answer is: it will bolt on and not fit properly.

 

So, my 4DR Sudan Hood got messed up. I was wondering. If i could take a E46 2DR M3 Hood and custom fit it on a 2000 323i 4DR Sudan?

M3 hood is wider, taller than even the non-m coupe hoods, sedan hood difference even more (not as long). it would take some pretty good modification to fit. stock M3 is aluminum so it’s tricky.

 

Short answer - no. You cannot use a M3 hood on your sedan. Plenty of people have asked, few have even tried, and all have failed. A more common approach is to get a sedan hood and customize that to look more like the M3 hood with the power bulge, but even that is tedious and costly (custom fab power bulge, bond, sand, level, paint, and the paint alone could cost $1k if outsourced to a pro shop). Another method is to go aftermarket, but fiberglass hoods are not nearly as well made as OEM. Best to stick to OEM sedan hoods and source a replacement for your car.

Here's someone that went through the trouble: My DIY Hood
They had to stretch the fenders out 3/4" and extend the front 1" to properly fit the hood + custom fab and paintwork. I'm unsure of proper functionality and fitment though even after all that work, you can come close but it'll be difficult to be spot on.

+1 on this. A friend's 330i has a fiberglass (or some type of composite) hood on it that her son put on at some point, and it's not the best fit. You have to slam it down to get it to latch closed and even then it looks like it's unlatched in some areas.

 

As others have mentioned, it's not a bolt on affair. For one, the coupe fenders are longer as well as the pillar area being shaped a bit different. You're better off just keeping a pre-facelift hood unless you have time and money to spend on this.

I converted to an M3 front end using conversion fenders from 2M autowerks for my touring, and modified metal fenders for my sedan. Once the fenders have been modified and fitted, you are then able to fit the M3 hood, M3 front bumper, and M3 headlights if that's the route you wanted to go.

 

I did it. It’s not perfect, but I think it fits pretty well. Took a little work but not nearly as crazy as all these guys make it seem.
