Ideal C240 performance setup
very good thinking about the weight distribution. So say we have unlimited amounts of money to spend on the w203. What would the best setup be? Using the stock c240 2.6
1. ???
2. ???
etc
I'm curious as to the design of the heads. This motor was designed after the chrysler merger. It is possible that the designers used the Hemi-spherical heads for our cars. Thoughts?

You can get all the typical upgrades like headers, camshafts, high flow air filters, ECU upgrade, underdrive pulley, and exhaust. But the biggest mod you can do to improve the power output is a supercharger. Kleeman offers one.
If you want to improve the handling of the car, you can change the suspension setup (AMG or other aftermarket tuners), and change to wider grippier performance tires.
But if you're going to spend that kind of cash, you should also consider getting another car, like a 2nd hand C32 AMG, which in stock form is going to blow away a supercharged C240 anyways.

^A SC is a most excellent mod that adds at least 80HP right out of the box. As more money becomes available, you can add other parts (headers, exhaust, extrude-honed intake, chip). This setup is much stealthier and will not cause your insurance to go way up (like it would with a C55). Won't have the headaches of buying a used car either.

Ah, forced induction can be added to a C240. I'm assuming that you are refering to Japanese imports featuring turbos (which are a poor substitute to a SC - coking oil, short-lived turbines and lag) which would to me be a waste of money. If you really want power, get a large displacement crate motor and put it into a 1970s era muscle car.

Dyno numbers would help a lot. I would like to see the price you paid for those mods and then the amount of hp you gained.

As far as Japanese turbo'd cars, sure why not? I had the same t3/t4 turbo on my eclipse for 4 years. Never blew smoke or anything. As far as lag goes, I had full boost by 3300 rpms. 400 hp on pump gas. Not to shabby and not that expensive.
I agree with you on the crate motor. There is no replacement for displacement.

I know it can be added to the 240 but is it really worth it? Why not buy a car that is already fast?

For me it's Euro class or American muscle.
BTW, I just saw how much a Kleeman K kit costs. $9,500? Are they freaking kidding me? I would just buy a universal Procharger kit and have a specialist re-flash the ECU for half that price. A centrifugal sc can be placed almost anywhere (and there is a intercooler kit for it) and simply requires a little engine management (retard that timing!!!!) to take full advantage of it.

I'm not a fan of most japanese cars. I loved the Turbo'd Eclipse, Talon, Plymoth Laser years... 1990-1999. They were so easy to make power.
Guys with non turbo eclipses would always ask about throwing a turbo on. The most common answer was "sell it and by the turbo'd version." Which would pretty much apply to NA and SC'd benzes as well I would think. I couldnt imagine spending 9500 bucks to SC my wifes 240. Her car is staying stock aside from a few cosmetic changes. I would have bought the c230 if I was going to mod a benz.

I would....
Higher pressure fuel injectors,pump,and lines
Centrifugal Supercharger + INtercooler
Port& Polish
Change pistons
Change heads
Change rear-end
Put on wider tires at least 265 on the rear, 235 up front
Headers- no cats, resonators, mufflers, nothing. Straight back
Change intake box to intake tube with a cold air box in the grill
Upgrade suspension 100% + sways
Weight reduction (gut it and use racing seats)
Pulleys + custom cam pulley
NOS direct injection kit (cheater gas)
ECU reprogrammed to match the above
Replace steering wheel
Change tranny to manual
What kind of hp could we see from all of that?

2006 C230SS Blue/Black, 2003 SL500 Silver/Black
SC/Intercooler = 95HP
Injectors/ECU = 20HP
Wiseco Pistons/Bore Cylinders = 35HP
Port/Polish Heads = 10HP
Pulleys = 5HP
Nitrous = Wouldn't do it but it comes in stages 50/75/100HP
Cam = 10HP
Screw the tranny change, would be very hard and expensive.

Sorry to quote it all but...
Fuel: You will need bigger injectors, high flow pump, bigger fuel rails and a fuel pressure regulator....
Ported Supercharger: fine...
Higher compression pistons AND rods... The stock rods and pistons are not designed for forced induction.
Change heads? Probably port and polish, stainless valves, valve springs, arp head studs, thicker head gasket.
Rear end: Ford 9 inch?
Wider tires: sure why not. If were going to spend 20k in mods, might as well.
Full 3 inch exaust: Sure, aside from not passing emmissions, might as well.
Suspention: springs and adjustable struts and camber kit. If you are into twisties, sure get the sway bars, polyurithane bushings...
Pullys: from my experiences, they didnt do much for me.
N20: meh...
ECU reprogrammed: Throw out the stock ECU and get an aftermarket Engine Management System.
Replace steering wheel: What is wrong with the stock steering wheel?
Change trans to manual: On a benz, this will easily cost around 8-10k dollars plus labor. Not worth it one bit.
Basiclly, after all this work and money, were looking at a 300 hp car...

c240
C240 upgrades
I know this was written in 07, but I thought Id ask everyone out other there anyway. What kind of power (HP) did you get out of these mods?
I am doing the same mods listed now on my 04 c240 plan I AMG Exhaust, K&N air filters, ECU upgrade, and EVOSPORT UD pulleys. looking to do the headers too, but running into snag wondering if doing the headers and mid-section will really improve my overall peformance ontop of what I'll get with the prior mods listed above. Do I go with log or short headers What did you do after the mods above. Anything?

It sounds cool but its not worth it.. I wouldnt expect much hp from the mods and the cost to hp gain ratio is terrible..
You could do all this work to the c240 but in the end you could have just gotten a c32 and had a lot of money left over to make it even better than the c240 will become. I had a c240 and really considering going all out but the price to pay wasnt worth it.
