C240 to 3.2 engine swap anyone done this?
What other mods did you have to do to achieve proper functioning apart from an ECU reprogram?
Before anyone harps on about me wasting my money, to upgrade to a 320 from a 240 w211 would cost me an additional 10k on top of selling my car, plus 95% of 320s don't have a nav system in them lol, and I really really love my car (I'm sure everyone will understand that one) but it is a tad slow.

i had the 2002 c230k, my body have a 240 and i now i drive the 320... the 320 is simply the best engine in that list...

my idea was a motor show testing luxury cars, super cars & BIG engines... nthn like that in here.. they dont care about big engines in europe...( as long as its not an entertaining show).. its mpg, and lower tax because of low co2 emissions and stuff like that... you'd be amazed by the number of people willing to spend more to be greener...

It's how engines produce their power. I like revving engines & the 240 power curve looks like this. If you want stump pulling torque at low RPM then the 2.6 is not for you.

I'm picking up a 2003 C230k on Thursday. I definitely enjoy the car, but the ultimate goal is to get the engine up to about 450 rwhp. The 1.8 can't do that, so I've been kicking around options like:
1) keep the body I'm picking up tomorrow, but swap in an s/c m112. Doing this will cause all kinds of transmission problems (it must be manual, no autos!) and fit issues with the ecu,
2)Drive it around for a few years, then actually buy c55 m113 and add a supercharger to it from renntech. Option 2 is much more money, but better payout with respect to power gains.
The basic issue is that I need to learn a lot more about what's available for MB tuners, but I want something fast and unique.

Also it will be a very difficult swap. The C280 uses the M104 engine, and the C320 uses the M112 engine. The M104 is a straight 6, while the M112 is a V6. All sensors are different, SAMs are different, the computer is completely different. Hell, I don't even know if the M104 computer could be re-mapped to run efficiently with the M112. I wouldn't consider the swap.
Well, swapping the engine in won't fix the transmission problem, if that's what you're looking for.

Late in the day I know..
How did you manage to change the ecu coding? I tried to do so but kept getting e26 on the dyno screen.
Help wold be much appreciated.
Thx
So, it's a cool way to really upgrade a C240 if the engine is to be replaced.
I'm thinking about doing the same with mine. So what else did you need to swap over besides the engine?
