Can someone point me in a good direction for performance parts for a 1994 E320 Sedan, currently interested in exhaust upgrades, and ignition

All going to depend on your state regulators.
I had a Magnaflow 3 1/2 inch free flow cat put into the middle of my system with a straight thru muffler at the back. i believe it has given me a small improvement in performance (can't dyno so can't tell) but it sounds a heck of a lot better.

Have it set to factory specs and it's as good as it gets...
Not bad performance for what it is....
Wrong choice for performance without spending several times what the vehicle is worth.
No inexpensive aftermarket parts available.
High flow cat like the Magnaflow spun metal design will give a very slight increase in power..
If you want increased acceleration then change the rear gear to something shorter...

If you can source the rear diff from the 1990 300ce, that should put you at 3.27 final drive.

I chose the car cause I like it and Im capable of doing all my own work, Iknow im not goin to get it blistering fast its actually resectfully quick for a budget sedan, just wondered if anyone produced ignition upgrades or a cat back system before I start building my own parts. I dig the rear end change but I like the ability to cruise 120 down the highway dont want to loose that.

The 3.27 diff and non-overdrive trans should put you at 120 mph at 6k rpm. Not exactly cruising but doable. There are always trade offs but basically HP = $, how fast can you afford to go. A good used larger engine from a different model might be a reasonable way to go. Getting the computers to cooperate can be a challenge but can be done. I am clueless as to what engine would match your trans and you might end up swapping both. Getting as much HP out of your engine as you would get out of a larger one would cost way more.

Of course if you have some dollars you could do this



An M119 transplant (drooooll)

You can be extremely mechanically adept but you need to know what your dealing with.
I say this because the questions you are asking indicate you're not familiar with the Merc power train.
Not sure what parts you can build that would enhance performance.
These engines are very sensitive to deviations from factory settings.
Have you taken the time to pull your plugs and read them?
Compression and leakdown test?
Without baseline knowledge you'll just be spending time and money with minimal results.

Mercedes built a good deal of performance into the M104-24V.
It's not very sophisticated and the ignition is for the most part three primary coil packs.
Also get familar with the HFM system
Can't change the timing or the fuel maps they are what they are.
Cat back doesn't give you much of anything as far as performance.
I'd be more concerned with whether you have degradation on your engine bay wire harness.

As I stated before get it to spec, meaning all to factory settings, check out the wire harness and of course clear up any vacuum leaks.

You're looking at around $100 per additional HP ( e.g. 100HP = $10K ) to make any noticeable gains.

The change in rear ratio will not give added power but it will probably cut a second off in 0-60.
Gearing has always been the least expensive way to gain acceleration.

I am planning on doing this! M119 in a coupe. Aint a real project now since im waiting for the perfect donor car first. Link me the thread if you got it.

I keep having visions of the 600 engine in my 300 te. It is not unusual for just a proper tune up and insuring things are at spec will give significant HP gain on an older car. A small missfire or a marginal sensor throwing the mixture off can really suck the HP.

Has anyone done a Megasquirt FI system and crank fired ignition?

just try to make it look better, don't worry about trying to make it go faster... 20 years after they were built options are limited, parts are scarce, and everything will cost a lot of $... these cars are not the right platform to create a tuner car. you already enjoy cruising at 120, which is what the car is perfect for, not sure if it's worth the expense to get to 120 a few seconds quicker than you can now...

Same with wagons and 2.6 liter W124s.
