C43 '55' swap thread
That would be awesome if you could arrange something. If not maybe tell me exactly how he reset the tranny
I honestly feel like Id start slowly pulling on him if we kept going but due to traffic we both had to slow down.
my car is stock with the 5.4 motor swapped

does it run properly now?
when yoy say your car stayed DEAD against the M6, what you mean by that?
could you barely keep up with the M6?

I sold my other C43 to fund it, so I don't have another car. Being pressed for time without a car, I won't be doing anything other than the direct swap. I'd love to have a day or two with the car+engine on my own to a few things but that stuff will have to wait (plugs, valve cover gaskets, etc) because I need the car back ASAP. My current engine needs all that stuff too, plus a timing chain, so I'm just starting over with a 5.4 with WAY less miles. I am SO EXCITED. The C43 is barely considered "quick" in stock form, so I'm really curious to see just how much of an improvement in performance awaits me when it's done.









Edit: what the hell? Exhaust shop says they can't remove any type of cats from any car because it's a minimum fine of $2500. They don't even smog test here, and I live in Tennessee! What on earth???

P.S. In my opinion you need to find yourself another exhaust workshop
P.P.S. Cruising speeds doesn't get you any intrusive noise with the cats and resonator deleted. Other modern vehicles make much MORE noise than the C43/55 IMO








with stock C43 engine some magazines tested this car on a track getting 5.9 or 6.5 seconds 0-100km/h???
don't know what is correct sprint time for a c43 engine?
what is the sprint time 0-100km/h with an E55 engine mod?




I imagine that a sub 6 can be easily achieved with a later 55 engine (367PS)
If an E55 can break into 4s than imagine a c43 with the 5.4 engine.
6.5 seconds is ridiculous. I dont know where you got that.




New engine arrived at my mechanic's shop. I got to go over and inspect it with him. It came with a surprising amount of stuff from the donor car. It's only missing AC compressor, alternator, and air filter box.
poured over it with my mechanic to come up with an idea as to what we should do to it before it goes in. he is very adamant that I go ahead and put on a new water pump. I told him my old water pump is only about 20k miles old, but I think he still wants to put a new one on there.
he is also very serious about using the intake off my old engine. he pointed out the diaphragm on the donor car's intake is extremely rusty. I think the donor car/engine has been sitting for some time. the water pump barely turns, everything that can rust is very rusty (EGR pipe connecting nut is very rusty). I'm going to be buying all new plugs for it, of course. the NGK's in my old engine went well over 100k miles and are still very healthy.
I always avoided dumping cash into my old engine because of how many miles it had and how I would rather just wait and do it right with a 55 engine.
I'm going to keep the E55 headers off to the side just in case I ever get adventurous and want to find a way to make them fit in the w202. I know the stock 43 headers are a bottleneck and draining some power from these cars but anything else doesn't fit.
I assume I'll need new exhaust manifold gaskets right now?
