Piston Slap: But, But, But…It Has a Stick!

Jack writes:I have a W203 Mercedes-Benz C 230K/1.8L. Would a rear-drive GM DOHC 3.4-liter V6 with a turbo make the 300-plus horsepower I think this car needs? Would an LS V8 fit? Would a 392 Dodge Hemi fit? Unless AMG, even the Mercedes-Benz V12 is only 5.0-liters. My car has the six-speed found in manual transmission Camaros.Thanks!JKD Sajeev answers:ZOMG those came with a T-56? Why would the dark ages of Mercedes’ engineering implement a gearbox so totally overbuilt for a W203? That’s totally not possible. I think you have this unit, and with that in mind, sell it and get a C55. Look I get it: this is a non-stereotypical performance car with a factory manual transmission. As the years go by this’ll be like a frickin’ 1969 Camaro to all the autopilot-driving conspiracy theorists that loathe our (their?) fantastic future. But even if you had a T-56 in that wee beastie, odds are the bellhousing wouldn’t fit an LS. Or any other high power engine available outside of Affalterbach.Not to totally kill your vibe, here’s a quick video of a friend’s E55 AMG powertrain swap.

And it took him years to get all the Mercedes parts talking with each other! So interfacing with Mercedes’ CAN bus electrical system with non-factory parts? Oh hell no, son, ain’t nobody dumb enough to do so much work for such a useless vehicle. I mean, you really have to be touched in the head to tackle such a project.(Looks back at his idiotic project car and the current hurdle of getting modern Hella H4/H1 lights installed.)
Misery enjoys company. You go right ahead and do an LS swap, including the T-56. Disconnect any warning lights that come with possible CAN bus rejection. When complete, it’ll make more sense than my restomod.[Images: Lead image: Shutterstock user alexkich.

If you're serious, buy a good running '02 manual Z28 Camaro (LS1), use the entire GM wire loom, ECM, emissions, etc, and graft in the GM gauges/instruments, splice in the Mercedes HVAC, and upgrade the diff, drive shaft and suspension to AMG or equivalent. Or just get the damn AMG car.
Almost any engine will fit in any car if you've got enough money and time.
