Kompressor Questions
I have a question regarding the superchargers used in 2002 C230K Coupe and 2003 C230K Coupe. I understand that the 2002 has a 2.3L engine while the 2003 has a 1.8L engine. Who makes the supercharger that is used in the 2002 C230K? And who makes the supercharger that is used in the 2003 C230K? Is there any major difference between the two? Thanks.

The 2003 uses the all new 1.8L M271 engine- the C230K Coupe was its first application. Its also in the C230 Sedan, and the upcoming new SLK(supposedly making 200HP in the SLK). It makes 189 HP and 190ft-lbs of torque from supposedly 10 or 11 pounds of boost from a modified M45. By many accounts, that's the upper limit of boost from the M45.

just a minor correction: C180, and C200k both use the new 1.8 engine, so the C230k really isn't the first application. 180 being n/a and 200 with less boost from the s/c.

The previous model years used motors with displacements indicated by the badging.

oops, nevermind, should've said 180k not 180...

I'm not being a cheapstake but its just that this new 1.8L C230K is not available through my country authorised MB agent.

No, that wouldn't work, because of the different boost levels and compression ratios.

Therefore I believe changing of ECU is able to increase the power from engine. Moreover the displacements or rather the entire block is the same.
But I have noticed that there's another mechanical aspect which is not quite the same between the models are its gearbox ratios (or just simply a different final drive).

Nope, boost is not controlled by the ECU. It's controlled by how fast the supercharger is spinning. You can only control boost with the ECU on a turbo.

But would the C180K ECU able to handle the addition fuel feed of a higher boost?? :P

As for fuel, there are different fuel settings and these can be changed by the dealer, and it changes the air:fuel ratio under certain conditions.

If that is the case, changing of pistons are not sufficient, we might also need to upgrade the crankshaft, conrod (& cam maybe?).

To change the pistons, the engine must be removed from the car and disassembled. The oil pan must be removed to get to the rod bolts, and the intake and exhaust manifolds must be removed. The the head is removed. The pistons are pushed out their cylinders. The pistons must be separated from the con rods by removing the wrist pins. Now install new rings on the new pistons. The reassemble the pistons, wrist pins and con rods. Using a ring compressor, slide the piston and rods down the cykinders. Using new rod bolts and bearings, the rods and rod bearing caps are reassembled to the crankshaft. The oil pan, head, manifolds etc are reassembled. The engine is reinstalled in the car. This is just a brief sysopsis of the process. It is much more complicated. It will not be cheap, and I don't think higher compression pistons are readily available. They will be $$$$.
Now we are ready to use the engine, right? Wrong. The ECU might need be remapped if you are still going to use 91 or 93 octane gas. The engine will be more prone to detonate with the higher compression, so the ECU will need to retard the ignition advance. To make sure, you will need to do several tuning sessions on a dyno. On the other hand, you could use $4 to $5 per gallon racing gasoline.
Now, the engine is ready to go. Enjoy the break in period.
