BS Delete
I looked all over this forum before I posted this to make sure it isn't a double post...
What is the MM Balance Shaft delete kit going to do for me? I understand that it will make my car a little more shaky, but what kind of performance gains would I be looking at, if any?

It's just a shaft with two weights opposite each other, only transversley mounted engines have them due to shakiness and vibrations. I heard it was a good 30 dollars spent though....

just remeber no one knowes the long term effects yet. there are extra vibrations in the bearings and all the negine parts when you take it out...
with that said, walter marcy is pretty much all but shut his doors...
buy the bs delte from cosworth please

How hard is it to take them out?

the 2.3 and 2.0 are different blocks... from different assembly lines

not only different blocks (if that's true, I don't know)
but also different cranks.
2.0 duratec's don't have a large gear to drive the Balance shafts.
Also 2.3 ranger cranks also are not equipped with balance shafts.
If the 2.3 ranger doesn't fall apart after 120,000 miles, why would a focus?
It's there to improve the "harsh" cabin conditions from having such a large displacement engine in a small car.
However, the removal of the assembly only add's minimal vibrations.
By minimal I mean, My girlfriend noticed it before I did, and after I installed a rear motor mount the vibrations got at least 2 or 3 times as worse.
Usually people with new motor mounts don't complain much - same thing with the BS delete - no complaints from the added (NVH).
NVH= noise vibration, and harmonics.

scale from 1-10, I'd say 3 or 4. (It's easier than installing a header on a duratec)elliottcarlose said:
Removal of all of the oil pan bolts, and prying the oil pan without gouging the surface where the gasket meets is the hard part.
There are area's where prying the pan doesn't damage it. Use caution and patience and the oil pan will come off with very little difficulty.
Once the oil pan is off, the 4 big badass bolts holding the BS assembly in place need to be removed. They are torqued on good. I was not able to budge the bolts the 1st BSD attempt. I injured myself from the stupid 8" ratchet. You should have a big breaker bar or torque wrench to undo those bolts.
beware: don't remove all the bolts all the way (leave 1 or 2 half-threaded). If you remove the 4th bolt, the BS assembly will come crashing down on your face or body. (remember it weights close to 20 lbs)
also oil will break out so, Be sure you have 2 oil catch pans (1 for the oil draining, 1 to catch the BS assembly)
The actual installation of the part takes 2-5 minutes, the oil pan removal and replacement take up the other 35-120 minutes depending on tools, and mechanical skill.

so, i guess the question is......is it worth it to do this? i need an oil change soon anyways, so maybe?
do you need to buy anything before you do it? or can you just take it out?

You need to buy a bs delete kit. it has a special plug and a cover. Your oil won't feed properly if you simply yank it out.

marcymotorsport.com was the original source of the BS delete kits.
however, his business is slowing down, so call to make sure he has them in stock.
otherwise, order from
http://www.newedgeperformance.com/index.asp?PageAction=VIEWPROD&ProdID=275
or cosworth
http://focussport.com/cosworth-deletekit.htm
Both parts are exactly the same as far as purpose, except cosworth uses a threaded screw with an O-ring, whereas marcy uses a plug that's tapped into place.
