I have a 2002 c32 with a blown engine due to cam spinning, I can get a complete 2005 srt6 supercharger and all. Is it a plug and play with the wiring harness and oil pan and such ?

g'day mate, can't speak for the SRT but I also spun my cams on my C32, and ended up with an SLK32 engine, both lower oil pans had to be changed, oil pick up pipe, and I think the water pump was located differently. luckily wiring was able to be adapted. Not exactly an answer but just some things you may need to keep an eye out for.

Got my engine through Land Auto Dismantaling in the US and they shipped it to Australia. fantastic company to deal with. Good Luck.

Seems like quite a problem with these m112k engines. I wasn’t aware of it until I bought this one with a blown engine. Dropped all 3 exhaust valves on one side and destroyed the engine. Good job Mercedes, you’ve managed to over engineer another part.
was your car pullied?

aus-C32

yeah pressed lobes on a performance cam, makes sense right? I got my cams checked and got the all clear.
I think up to the 02 had this problem and was changed. I bought mine with a dodgy engine, thought it was a bent valve, ended up punching the oil pump out the sump. If by pullied you mean a smaller supercharger pulley, then yes, it had it, same charger and pulley on new engine no problems now.

The car I bought had a 178 crank pulley on it for some time. I assume the extra boost must somehow increase the combustion chamber pressure putting extra pressure on the cam lobes when opening them. The car I bought also has a full exhaust with stock manifolds. 74,000 miles

oh right, no my crank pulley was standard, I don't think it was your mods at fault, id place the blame squarely on the s#!t camshafts! My engine had 115k mi on it, and new one has just under that, put an ecu tune, belt wrap, cold air intake, stock exhaust with cat delete. The ecu tune and cold air intake make the supercharger scream if that's your thing, I love it.

It seems that the modified cars succumbed to this issue much quicker than the stock ones. More boost and exhaust changes seem to accelerate this cam issue

Ok got the srt 6 engine, and the differences at the the visual seem to be the exhaust manifolds, oil pan upper and lower,wiring harness has a 170 part number, ( from an SLK 32 I would guess) and the supercharger seems different in the pulley area. All else seems the same. Maybe the motor mounts are SLK as well. I will update as to what comes further.

I will say that at this age of the car finding a decent running used engine is not easy.

if you still have the old engine, hopefully you can use some parts off the original engine and piece it together. it saved me alot of headache and money, good luck I'll be following your progress 👍

I actually have 3 of them now, the first is a long block that I bought and put it in , only to find out it has a bent crank snout from a front hit. The next is the srt6 engine.

The bent crank one and the original piston damaged one will be combined to make an extra engine. Just dont want to use the early cams

cdk4219

So the srt engine is indeed an slk32 engine. Oil pan upper and lower, wiring harness, exhaust manifolds, motor mount pedestals, rear heater hose off of head, oil pump and pickup, you must take 2 main cap bolts off of the c32 engine to bolt the pickup tube to, and the bolt hole in the rear of the passenger head that holds the dipstick tube on the head needs to be threaded. That’s it.


I will say this is the cleanest used engine inside I hsvd ever aeen

compared to 73,000 miles from original car
