2001 BMW 330Ci differential?

So I just bought a 2001 BMW 330Ci M sport, from what I've read apparently this car does not have a Limited Slip Diff. I know I could do a M3 rear end conversion but I'm curious, are there any aftermarket two way adjustable limited slip diffs for this car or the M3 rear end, I want to have ar to be a solid street car/daily driver but also to have a little fun as well. I don't plan on any preformace/engine mods. Any time soon or even at all maybe. Has anyone ever done the rear end conversion by themselves, if so was it easy/hard? How much time/money did you put into it, etc? Every thing I've searched people are saying they had a shop do it and it cost them around 1000-1500 dollars for everything. I could save money by doing it by myself but if it's going to take me months to do with tons of fab work then I'd rather take it to a shop and spend the extra dollars.

Honda accord 2001 seconds delay in acceleration at low speeds?

i have a 2001 accord ex coupe with 145000 miles on it the car has a acceleration problemas When pressin on the gas too fast it feels like the car has a second delay for gas but it doesnt affect acceleration if i do press on the gas pedal slowly it doesnt do it, also i hear a tickin sound coming from underneath the car like on the middle of both rear tires. if anyone can help i would appreciate it also the car does that delay at slow speeds once i hit 45 doesnt really do it well sometimes is rare if it does what could it be?
I changed the spark wires, spark plugs, oil change, transmission fluid. a friend of mine said his jetta did the same thing and it ended up being some hoses connected to the fuel pump. as I said it drives and shifts smooth

my samsung mega isnt holding to the chrome plate its sticks out a little what is the part i need to fix called and how much would it cost?

It all depends on your skill, how your workshop is equpped, and the shape of the car.

If it is rust free and the drivetrain doesn't need much work and interior is somewhat intact, could be within your budget.
