Look for HWA stampings
I still need to get clearance from the local road transport department regarding the XXX XX overlapping stamp marks on the engine number.
I estimate that would need 2 weeks to clear. Hopefully, I should complete this project before I leave for Brisbane Australa, on 25/09/2013 to visit my daughter studying at UQ.
Oh! car forums are so powerful. I had this generous offer from a nice gentlemen from the BMW E24 group in Gold Coast. Thank you Addam!

The engine has finally been transplanted yesterday. We made use of the C36 intake manifold & ignition coils. Air pump was deleted by my mechanic. All the rest i.e. ECU, sensors, wire harness, throttle body, 5 speed auto transmission and rear differential are from the C280. Note : the 280 is 1997 and has the newer type wire harness, sensors, electric throttle etc.
Had a short drive around and note that the car take off is slower than the 280. Once past 3500 rpm, the car do pick up speed faster than the 280.
Is it suppose to behave like this or did we miss out anything? Could it be possible that the fuel injectors are partially clogged due to not being used for a long time?
Are the injectors from the C36 different from the C280? I was thinking of putting in the C280 injectors to try and see if it makes any difference. Would deleting the air pump cause this?
Quite disappointed with the out come. Suggestions and opinions from members who have gone this route is most welcome.
You definitely missed something. A C36 easily, easily takes off faster than a C280. It should be a very noticeable difference in all areas.
C280 0-60 time is about 8 seconds
C36 0-60 time is about 6 seconds

Did you flash the ME to C36 spec ?
Something must not be right. The difference should be immediately evident. Do you have the C36 ECU?

......dang now I know where all my money went.
You can start by checking the intake resonance flap and variable valve timing.

sounds like you need to flash your ecu or swap in a 36 ecu and or make it work Also werent the c36 m104's cable actuated throttles ? not fly by wire. dunno but this could make a difference in throttle response as well. I know for sure the pedal feel is night and day from my 96 c280 ( cable actuated Throttle body m104 w/vacuum controlled 4 speed) to my 99 C43 ( 5 speed electronic, fly by wire TB ) Sure the 43 is much faster but the over all pedal feel and throttle response when i press it down is noticeably different feeling between the two. just a thought. How much do you have into this swap so far ?

Up to 96' is was throttle cable,
97' + was wire.
You need an SDS and change variant coding to C36. You should be able to do it with your current factory C280 ME
Guys, I have good news. We replaced the cam sensor and the engine behaves quite well. Off the mark is back to normal. Form 4K rpm the engine races to the redline quite rapidly. From this mid RPM's the engine fells like it just want to keep going. It runs very much better. I guess a remap or aftermarket ECU will work better than this C280 ECU.
Thanks a lot for all the inputs.

I would still keep an eye on air/fuel ratio ...
This C36 engine has the famous diesel noise. From what I have read in a few forums this is quite normal. Looks like I will live with it rather than spend money chasing a ghost.
Fantastic news! Although you have now opened the door for me to consider a C36 motor swap into my C280 as I was going to do a bare block swap just as you have done. I see now that it does work......decisions decisions.

Don't jump on the band wagon yet. A friend who has driven a real C36 has commented that my car is far from the real thing although he agrees that it is now way better than the C280.
I do have a few issues just like RemoLexi said : keep an eye in the air/fuel ratio. The engine has stalled a couple of times when after starting, air cond turn on, gear engaged and as soon as I turn my steering. Probably due to fuel starvation. Idle RPM is less than 600.
I have tried enquiring about ECU remap/flash but there's no trusted expertise in Malaysia that handles Mercedes.
Does anyone knows of a known source in this forum? From checks on the internet I found RennTech in FL who seem to do a lot of work on Mercedes. Anyone here uses their services?
Another issue is the engine temp. Seems a bit high (almost 100 C) almost all day. However it has never gone past 100 C. I had new water pump and thermostat installed during the engine swap. Clutch fan and auxiliary fan works as it did with the C280 engine.

Only way to really make a C280 act like a C36 is to swap it ALL. Engine, ECU, Transmission, TCU (if it has one), intake, exhaust, etc etc.
In a nutshell, I'd only do it if I found a totalled C36 that couldn't be saved. It'd still be cheaper (in most cases) just to fix a wrecked C36 than to swap all that crap over to a C280.

A C36 engine swap is just wishful thinking on my part. With real C36's selling for peanuts around here it is not financially feasable to take on the task. I do believe the fuel pump is different for the C36 to provide additional fuel to the engine so I would look to see if tyou do have a fuel starvation situation.

I had the exact same plans for my W124 E320. Expected at least $2k investment into the whole project.
But then found a C36 on this forum going for just a little more, that only needed a little work. Owner never got back to me, and then I found a freaking C43 locally for even cheaper that needed even less work. Instead of having 50 more hp in my w124, I have 100 more hp in another official AMG w202!

As a cheap cheat- I am sure Bosch offers a 4bar fuel pressure regulator ... You may need one and also try cleaning the throttle body (flap contact points) which should cure your stalling problem, also test for vacuum leaks.
100deg. Temps seem normal from all the 202's I've had.
How I wish I am living in the states. Car are very expensive here in Malaysia. There are only less than 5 or 10 C36's here. Hence the choice of conversion.
Another alternative would be to get hold of a set of RHD engine wire harness and then put in the rest of the hardware. I do have the rest of the AMG hardware which is the ECU, 4 speed gear box, prop shaft, rear diff, drive shafts, air cond control panel, throttle body & meter cluster.
Would wire harness from W124 E280 or W140 S280/S320 be same as the C36? Just wanted to broaden my search alternatives.
