man why couldnt i have been that fortunate i spent 12 hours almost. cus i was cursing half the time. plus i could only get the car 2 feet of the ground. i ended up stripping out one bolt on the block, damn aluminum, and one of the damn studs on the cross member for the rear part of the mount. right now im feeling like a freaking lose cuz it all jacked. plus i had to cut the left side of the harness away to get it to spin enough to get that damn lower nut of. and i went through 3 u joints using my damn impact gun. My shit was so tight i couldnt get em to break even after i soaked em. what was the secret?

there is a company in either korea or taiwan, i forget which - that makes uprated rubber STOCK engine mounts for the protege. i found this out after getting all but the front mount from mazdaspeed - they have run out of the front one apparently. i was chatting to a guy in a mazda spares shop here in christchurch about my dilemma and he went out the back and bloody came back out with a big ass front mount. it's real stiff but it is still rubber - you can definitely get them.
if anyone is interested i'll make a call and see if he'll tell me exactly where they come from....

well, i installed my rear mount a few months back. let me just say that i hope you have a 1/4" drive rachet, several extensions, a hydraulic lift (not necessary but a helluva lot easier), swivels, 3/8" rachet with extensions and swivels, and pretty good bit of free time.

not as hard as everyone makes it out to be but i sure as hell doesn't hurt to have someone with small arms and hands to get back there to it. it took me abuot 3.5 hours including an hour lunch break and several breaks inbetween while i was working on other vehicles.

was it worth it?
oh yea. you definatly feel the difference from the first time you crank it back up. nice low rumble, vibration is a whole lot more than with the front engine mount. i wouldn't suggest someone that likes their car to ride nice and smooth to get the rear mount though. it definaly met my expectations though.

Replace
 

I just replaced my 2003 323 front back engine mounts. Remove plastic covers underneath engine. Front mount is easy 17 mm nuts and bolt just remove mount connected to body. The bolt nut is tight u will need a 500mm break bar ie long handle to break the nut.
The rear one is very difficult. I only removed the bit with the rubber connected to the body. 17mm socket then swivel then three extensions to get above engine then a long break bar ie 500mm. It took all my effort to undo it very difficult angles and effort to undo the three nuts. Then undo bolt i put a 17 mm spanner on nut then used extensions from front wheel side. The nut spins until spanner hits something. Pull part out put new part in loose. Oh forgot to say put jack under to take weight. The holes dont line up for bolt so have to play with jack and lever holes to line up. Put bolt in then the three nuts on. Took about 3 hours but im pretty slow no rush otherwise i stuff it up.
