I swapped out the alternator today. Figured that I should start with the known issue and get that out of the way. Also noticed that my intake boot was ripped. Praying that is my only problem at this point. In any case I plan on doing a compression test before driving her anywhere.

All future updates will be on my "build"/ownership/maintenance thread here: http://forum.e46fanatics.com/showthr...1082236&page=4
It's done, dude.

Look for a used engine. They're not that expensive.

I remember shifting from 2nd into 1st instead of 3rd. The car went sideway and the tires locking up. Luckily nothing happened

The only good thing about a money shift to first rather than, say, 2nd at a higher speed is that the engine has the most leverage to prevent an overrev in that gear.

I don't get how these shifts happen going into first. My car - I can get it into 1st only when the car is going slowing/coming to a stop. Most manuals do not have synchros on first and I can't imagine the force it would take to get it into first at more than 10 mph at most. Been driving manuals on Subaru's, Honda's, and now the BMW and never could shift into first at any real speed from any other gear. Even when I was tracking the Honda and BMW - never came close to it.

Not sure about first, but I'm pretty sure that my car has syncros between 2-3. Funny thing is that I, for a while now, have had instances where she doesn't want to go into 3rd. Usually, I am able to force it into it but it takes a good push. That actually happened once or twice on the cruise leading up to the incident. I guess that's what led to my unfortunate downshift, was trying to shift too quickly and it slipped into first .

simply not true. Lots of performance cars have steel synchros on lower gears (instead of brass), so they can be tougher to get into first and 2nd. They also use triple cone synchros on lower gears in some instances.

Ok - but are they going to be able to get the gears together at multi-thousand RPM. I have not tried putting some serious effort into it but I can't get my shifter into first until I am going very slow. Can't imagine the whine the synchos would make to match the gears.

Can't get my head around how these money shifts can happen.

I tried to do the high second to first shift last night - about 3500 rpm and 30ish mph. It did go in with less first than I thought it would but I had to really think about it to keep the lever from going to the right for 3rd.
