300E Performance at ANY cost

Hey does anyone know how i can lower that slow 7.5 0-60, besides the 1st gear start? Im really looking to improve my performance at any cost EXEPT RennTec (there just too expensive). Please help me, post anything you think will help.

Thank you

I think bekkers sells a stroker kit for the w124, you will have to call them and find out, as it is not listed on the site. That would probably give you 250hp or so. Beyond that, saw off the intake scoop that connects to the air-box... that will give you a little more performance. Another option is building your own supercharger for the car, which would be extremely time consuming. Mosselman also sells a bi-turbo kit for the m103 engine that is supposed to put out near 300 hp. It costs 6k though... plus installation.

Change differential to better ratio for accelleartion.

Hey thanks for the feedback, and this prolly a stupid question but what does a stroker kit do, and how much would you estimate they cost?

THanks for all the help

Just buy a 400e
cheaper in the long run
Lots around in mid teen$

its quite simple. find out where your nearest Brabus dealer is and tell him how much much horse power you want, and he'll put it in there for you o(at a cost of course with this kind of quality)
my father owns a BRABUS tuned 5.0 v8 2001 s500 and it rapes anything that comes near it. i havent been allowed to drive it due to my inexperience.
it contains a factory brabus stroker kit(stroked to 5.8 i think(?) and brabus exhaust and extractor system and supercharger. can you say ferrari killer???

The cheapest way to go faster in a six-cylinder W124 is to sell it and buy a V-8.

Not only will you spend the same, or less, you'll have a newer car. And thanks to it's stock configuration, your "new" V-8 will hold it's value better than your modified 300E. Modified MB's tend to be real dogs on resale.

If you want fast, buy an E420 and find a 3.07 final drive set. You'll be as quick or quicker than an E500.

for no $$$ out of your pocket you can make your 300E faster by removing every extraneous piece of unnecessary load (gutting the car out):

ie
entire interior except drivers seat & seatbelt
trunk panels, tools, spare tire

you can even go further removing HVAC system, a/c components, fluid res bottle/tank..you decide what pieces you leave intact

you can even do research on lighter tire and wheels- keeping rolling resistence down to a minimum

carbon fiber trunk/hood panels? some rice-type tuners can help you there

other ideas: drill out holes in the stock airbox, remove plastic undercarriage mud guard, fuel octane boost

in the end, if you can remove about 300-400+ lbs of stuff - let us know if you can get accel times down to your tastes (keep in mind- if mechnically the car is not up to par ie compression issues, trans slipping, etc,....this may turn into a fruitless exercise)

good luck

ILL TAKE MY SLOW TAKE-OFF I LIKE MY 300E ...AND MY LEATHER!!

[Badinfo]

You know... I don't understand why people get all defensive when it comes to speeding up our 300Es. Its a fact, those things are slow!!!! So lets be nice guys, not everyone has spent hours mulling over how to make our 300s faster... just to find that its almost impossible. Anyway, as far as a stroker kit is concerned... I really have no clue, something about new cams and pistons, to raise the displacement and max rpm, thats about all I have found out so far... ill get back to you on that. I just had a thought though... maybe to use the cold start valve to add fuel when needed for full throttle burts. Im not sure this would work, or if the cold start valve even dumps more fuel into the combustion, so I will be doing some research, but yea... its a thought.

Thank you

did u ever dyno tested your 300e, after that u can realize where to start

seems like ...making one's vehicle faster is not a 300e exclusive dilemma

peek over at the Hot Rod Forum- folks with the V8's. AMG cars are tweaking their machines for more power/speed too

ever since I can remember 'more power' and 'more speed' are always inticing

Look at it this way, the U.S. spec. M103 engine is rated at 177 HP. This is from a 3.0 liter, SOHC engine with 9.2:1 compression ratio, and full emissions system using a mechanical FI system. How many other 3.0 liter engines, EFI included, using a SOHC arrangement make more HP than that?

To make more hp you need more displacement, more compression, and be able to feed it correctly.

A stroker kit means that the crank shaft has been modified (or taken from another existing model) to provide a longer piston stroke, thereby, increasing displacement. Often, a larger piston is also used to increase displacement further. The trick is to balance stroke, bore, and compression ratio to end up with a viable engine.

I think the reason many feel it's not worth the effort is because you can literally spend thousands of dollars building such a beast only to find out that a larger, stock model still outperforms you. In the case of a 300E, this is especially true because after you've spent thousands building an engine, you still need to upgrade the suspension, brakes, tires/wheels, etc. And the interior still won't be as nice as a 400E.

Anyway, if you just want to increase acceleration, swap in a differential with a more favorable ratio. Stock is 3.07 for most 300Es, find a 3.27 LSD from a 16V or I think some wagons used a 3.46 or 3.64 or maybe it was a diesel model, I forget. Just keep in mind that your RPMs will be higher at any given speed.

The reason that most MB folks will discourage you from "speeding up" a 300E is the economics of it.

It just doesn't make any sense when there is already a much faster W124 sedan pre-built by MB, and available for an upgrade price considerably less than opening up your 103 engine and uprating the chassis components.

Look at this way:

Take a 1992 300E. Sells in my parts for about $20K. To get 250hp or more is gonna take some serious work. Probably $10K at least, more with brakes and suspension upgrades. So, now you're into your 1992 300E for $30K.

A 1992 400E can be had for about $25K. It's already over 250hp and has the chassis to match. To make it blistering fast, maybe take the $5K and add a new final drive ratio and performance wheels/tires.

The kicker? Car value. Remember your 1992 300E worth $20K? Even with $10K additional into it, you'll be lucky to get your $20K value back out of it, as highly modified cars sell poorly. So, you've spent $30,000 and have an asset worth $20,000 tops.

Take the 400E, lightly modify it, and it will probably hold it's $25K value. Wheels and tires might add, might not. Keep the OE wheels in case. You've spent $30K and have an asset worth at least $25K.

And for me, the real deal is speed/dollar. With a 400E sporting a 3.07 rear gear, you've got a car that's approaching/at 500E performance levels. Take the 300E and add $10K into it, and you'll be lucky to get 400E performance, much less 500E level.

Same money, more speed. Yah.

AMG owners have a different problem. They have no cheap and easy car upgrade. If you own an E55, you can't trade up to an E74 for $5K. If they could, I GUARANTEE no one would even consider modifying their E55.

And hey, it's your car. do what ever you want. Just don't whine and complain when things get complicated trying to build a 300hp car from a well-engineered 177hp one.

[Badinfo]

I don't think anyone is complaining about it being complicated, just that nobody has ever done it And I agree, its not worth trying to make a 300e as fast as a 400E, but I think its worth it doing the little things, like sawing off the intake scoop, and perhaps some tuning tricks, which I have yet to find btw...
