Performance mods for an E55 W210

Hi, I've been looking for an E55 W210 or C32. (Or maybe a C55 or CLK55 W208. But likely not. C55 to expensive). I have pretty much now decided on an E55 W210. They look pretty damn good with some rims. Have aged a bit in looks. But they have a classic look and seem very reliable. Compared to a C32 which looks newer. has more capabilities to increase power quite easily. But lack the reliability that the E55 W210 seems to have. I cannot ignore all the bad feedback I have received with the C32. The C32 seems to be a never ending repair bill.

Therefore, the E55 seems the one for me. As it's naturally aspirated, I realize that performance mods are limited. Compared to a C32 or E55 W211. I've previously owned a stroked V8 (spent $10,000 on the motor) and Nissan 200sx that ran 20 psi and had 220kw@wheels (spent $20,000 on performance mods) which was impossible to launch as car would either bog down or wheels would just spin. The car only weighed 1290 kg! The power wasn't usable as often as I'd like. The wheels would also spin when dumping the throttle at 70kms. I used to work at a mechanical wk shop so I had the capabilities to mod the car. However, that's the past and I don't have have a workshop to work on the car myself and I don't want to spend big $ on mods like I have in the past.

So when I find an E55 W210 (they are rare in Australia), I won't be adding a supercharger to it as I'm assuming that will cost $5,000+. What I am thinking of doing is exhaust, intake and maybe an LSD diff (possibly with a different ratio).

My questions are:
1). What performance mods would people recommend? And
2). Approximately what kw / hp and torque will those mods get me? Approximately what price?
I know the car has 260kw@flywheel (348hp) and 530Nm Torque. I've also been told that the car gets from 0-100km / 0-62miles in approximately 5-5.7 seconds.
I was thinking of a 2 1/2 or 3 inch exhaust from the standard headers / extractors.
3). But are the standard headers / extractors restricted? If so,
4). Would people advice to get aftermarket headers and change the whole exhaust?
5), Is the standard intake manifold restricted?
Basically, I want to know if its worth changing the whole exhaust including headers? And if its worth changing the intake manifold?
6). I will get an ECU re-mapped, But do I need to purchase an aftermarket ECU? Or can the factory one be re-mapped ie. timing & fuel?
7). Would changing the diff to LSD give better acceleration times? As I would think that when a rear wheel starts spinning, the ECU takes power away from that wheel.

So in summary, What performance mods would people recommend to get extra hp / torque and to better the 0-100km / 0-62miles times without affecting reliability and without spending huge amounts of $? Aprox price?
400-450hp and 550-600Nm would be nice.

Your feedback will be much appreciated.

Cheers
Simon.

For a naturally aspirated 12 yr old hand-built-tuned AMG V8 - any available mods can't be considered affordable from a delivered performance/benefit side.

1) ECU tune - USD400 here in the US
2) Fklywheel - dubious benefit
3) Kleeman headers - if available, definitely pricey

The othjer way to go would be a Kleeman turbo setup - there were a very limited # built in the US as "delaer upgrades" when the W210 E55 was new 99-2000 fantastic.

Be happy !

I should state that an E55 W210 1998 -1999 model is worth $22,000 - 25,000 with reasonable kms. For a 2000-2001 model, up to 30,000 here in Australia. So what may not be worth spending on this car in the US or GB (as I'm aware its a LOT cheaper in these countries), it may be worthwhile for me in Australia
Cheers

I think I'd modify e55 w210 by changing the intake and exhaust manifold (headers). The whole exhaust system and modify ECU. PRICE??
Has anyone done these mods? If so, worth the costs?

Or would it be cheaper /better to just add a supercharger / turbo?

Please remember your E55 has a AMG modified and hand-built solid V8.

The intake is already maximized: some have gone to carbon fiber air box to "reduce" engine heat transferred to the intake flow (dubious excuse, some just like the carbon fiber look) by adapting over a W211 carbon fiber intake : some have gone into the intake throat below the MAF and removed a minor obstruction there, then claim "smoother mid range response (dubious); some go to trick air filters (dubious). There is no intake manifod smoothing and/or a aftermarket intake manifold.

On the exhaust side, check with Kleemen on headers - one of the few legitimate designs as well.

I would recommend you reconsider your direction on "modding" a 12-14 yr old W210 - any direction (other than ECU tune from right people) is hefty on cost but minimal effective return.

hand built The intake is maximized

Headers including full exhaust minus resonator etc. plus ECU re-mapping seem a good option. &, or
changing the diff to LSD and maybe even changing ratio to get better bottom-end take-off / acceleration could also be a good option. In Australia, we have a speed limit of 110km/h. 100km/h on most freeways / hwys. Plus, even though some people will say that the Mercs computer is smart enough to take away power from a rear wheel that's spinning without losing power to the wheels as such. I still believe that there is less power to the wheels (more lost power) than what an LSD would lose.

Has anybody actually changed a diff? If so, did it work well?

Cheers.

You need headers, 55's are the same as a 430.
Here is a pic I found a while back just not been able to find it 'till now.
