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.
