LS Mercedes E420 Swap, Maybe?


Asked by Jun 06, 2017 at 08:40 AM about the 1997 Mercedes-Benz E-Class E 420

Question type: Car Customization

So I have a beautiful 1997 Mercedes e420 that actually other than fading
looks factory new in and out but the engine took a dump. Four years ago it
started to smoke and was burning two or more quarts of oil a month so I
parked it and literally forgot about it at our family farm. Running into
endless problems with a C3 project I am doing and having sold my other
Mercedes I grew nostalgic for the E420 and towed it to the house. For kicks
and giggles I replaced all the fluids, flushed the fuel system, new fuel pump
and filter, as well as a new battery but all it does is turn over but wont run. I
then remembered why I had parked it and think I am done with trying to run
the original engine. So as to my question, what do I do?
Budget is more of an issue to me than it once was, now having to
daughters but a can spend a few thousand on the project but really would
love to stay under 3k if possible. Maybe that is an unrealistic I don't know,
please tell me. I don't have a garage or lift but all the tools I could think of
and am handy at welding and light to medium skilled mechanic work. I have
rebuilt older engines, SB350 and early Fords but nothing with a computer. I
also have a great mechanical team of my two young daughters.
I always liked doing odd projects and just rebuilding the engine in the car or
a swap of the same engine doesn't sound fun at all. The 8 cylinder that was
in it only produced 217HP any way so no great loss. For the size of the car
I was always amazed at how well it would get up and go but it wouldn't
make me cry to have more power. I was thinking an LS swap but know little
of modern engines. I see lots of AMG low mileage online but that's been
done and I don't want the expense of maintaining an AMG engine either.
So please give me some idea and advice, if any of you live in Virginia and
like to spin a wrench let me know as well.

P.S. don't judge, all my Mercedes friends think I am committing a sin for
just thinking about doing this. Wait till I tell my Corvette friends I want to put
a 20B rotary in my 1981 C3.
