real c43 mods discussed within- check it out

[expo5.0]

seriously-

if i'm keeping this car much longer i am going to at the very least need 100+ more hp and most likely also a 6 speed transmission.

What is needed for the engine swap? does it use the E55s computer?

Who makes software for our cars that will allow us to tune them? who has made a stand alone type system work? what will work to allow the car to actually make 400 or 500 hp?

are fuel pumps/injectors/etc. from the higher output mercedes cars interchangeable (will they bolt in)

will a newer transmission bolt in? has anyone tried to convert? how impossible is it to source the other needed linkages etc. etc.?

at the very least if we can figure out how to get into the computer and adjust for more fuel (and figure out how to get more fuel). I'll figure out my own damn way to get some boost to it if necessary.

i know some people on this board know some of the answer to these questions. my stupid subaru will smoke this car with just $4k in mods added to a $9800 used car (that only cost $23k new anyways) and had like 160 awhp stock...

let's get some information out here and actually go fast

[yusuke280]

honestly, the 43 is an awesome car. but these 202's are so mod-unfriendly. i'd just keep it as a car for show.

i'd just concentrate on looks, while if you are serious about tuning and modification, i guess go on to another car.

[expo5.0]

it has to be possible to unlock it and get some stuff going

i already have other cars/have had other cars that are very fast etc. whatever-

it can't be as hard as people make it seem

[OCKlasse]

IMO, you're better off supercharging it then doing the swap. To me personally, it makes more sense for the money spent. Contact Nitrogen Balance on MBWorld.

You should check out the posts from Speedybenz. He's covered this topic before extensively. Probably the most knowledgeable member when it comes to performance tuning, especially with regard to the C43.

He's pretty much maxed-out the potential of the C43 in terms of engine and suspension. He eventually migrated to a C43 with an E55 engine swap. So it would seem his path would be relevant to what you are interested in ;)

If there's anything he hasn't covered that you're interested in, he'd probably be happy to discuss the topic further. He's helped quite a lot of people explore the potential of their 202s.

i have heard nothing but bad things about the out of the box sc kits- due to the computer tuning side of things.

however, that seems to be a likely first step.

I understand that the same sc can be made to fit on the larger motor down the road as well, correct?

Probably good to talk to the company/dealer regarding SC migration between engine types.

Well.....an Eaton M90 blower is not enough for the 5.5L engine, you would have to step up to the M112. Not too sure about the other types (Kleemann, Byrd's UK, etc etc).

You may also consider House of Power's s/c system.

i've talked to hps in the past quite a bit

their used kit is tempting as a starting point, but i'm not sure i'd be happy with my car with just that kit on it.

if i'm going to try to do this the car and have it be my project and not just my daily driver it's going to have to get decently serious.

i've also heard bad things about the hps kit's driveability (computer tuning?)- can anyone speak to that

i know you guys have said it doesn't fit on the 5.5L engine, but what about this
theres a couple other 5.5's on there too

[expo5.0]

don't quote me- but i believe the bracketry etc. etc. will all fit. However, one should/can use the next larger sized supercharger itself on the larger motor.

is this correct?

[omeyhomey]

the most you can get out of C43 engine NA is most probably 350 crank HP and thats with every trick I know in the book. Honestly sounds like you want a tuner car, not an MB. buy a C43 and enjoy the car for what it is, don't try and transform it into something it doesn't want to be (no matter how much $$ you throw into it, its not meant to be certain things).

[expo5.0]

it just shouldn't be this slow, lol.

what about the 6 speed? anyone?

[kameraguy]

Are you asking if anyone has swapped a 6-speed into the C43? Pretty sure nobody has done that here....not that anyone hasn't thought of this, but damn, these things get expensive :eek:

Or are you asking if there was a six-speed C43? That would be unfortunately a no.

[expo5.0]

weren't they 6 speeds everywhere else in the world?

[RemoLexi]

202's are such an assplug to mod performance-wise.

especially if your stuck with a 4-banger. :(

[c280nz]

a manual tranny never come out in the c43,
only on the c280s 23k and smaller.

it would have to be a full custom job, would need to get the pedal box and shift linkage out of a manual w202, and fit it to a similar box, with a custom bell housing. flywheel, shortened driveshaft

and as for a computer you will need to get a full stand alone computer installed, not very easy.
the stock ecu's cannot be tuned, ive read extensively into this.
the only thing that can be done is flashing new info onto the chip or replacing the chip with another one, not really tunable
possibly a good quality piggyback would be the answer, and the injectors mercs use are a pritty common bosch type, reasonably easy to get different sizes, fuel pump swaps are easy as it is an external pump.

if you go twin turbo with intercooler and water/meth injection, just with low boost i dont see why 350+ whp isnt obtainable.

and it may not have the high "wank on about in the pub hp figure" you seem keen on but fuk shell have as much torque as a mack truck

[jnolte]

hmm benzmac c43 runs 11 sec quarter miles

Take a look at this thread from one of the other forums. Same principal. Might help

Sell your C43.

[cfourthree]

expo I can honestly agree with you in every single aspect possible with wanting more from this car. I am a speed junky. I used to drive a vw jetta that would smoke this car and most of the benz's on the road today (granted the jetta put down a bit over 500whp with the help of a 6cyl motor, 2400# car and one very big turbo). I miss the power, but like the other guys are saying in this forum, the c43 covers the "cushy" factor. Its comfortable and doesnt make stupid noises and seems to be very dependable. I have modding every car I have ever owned with Turbo installs, Nitrous and so on. They never drive the same again.
But if you would like to solve your power issue. Many dont like to spray and I have no idea how a MB motor would take it, but run a Wet nitrous system and you can add any ponies from 25-1000hp.
I am looking into having a friend make a turbo system for my c43, it would have to be a rear mounted turbo as there is NO room in the bay at all. I think a c43 with standalone and a gt35/40r turbo would be fun and good for about 5-600whp. :D

[kameraguy]

Just to throw it out there...

How about an engine swap to something more "tuneable"?

The Toyota 2JZ inline-6 has been dropped into MBs on several occasions (with aw202 being a receiver as well) and you can "easily" mod that motor. The benefit is it's been tried and proven to be able to take those obscene power gains.

For the cost of going all-out on a MB V8 and for the gains you'd expect, this suggestion may be even cheaper and more logical for the high-HP gains I think you guys are trying to achieve. Think "any Supra" that has over 700rwhp in a w202.

But just don't forget to neglect the transmission and brakes :)
