Need your oppinion..

Hey guys, I was thinking of figuring out a wy to put a turbo onto a 2005 c230. I know there arnt any made for it, but I figure if I could take one from an engine about the same size and hire a performance shop to figure out how to put it on, that would be really kickin. Super and Turbo charged lo. I also know if I was able to do it I would need new headers, Exaust, possibly a new intake, and definetly a new ECU specially programmed.

If I could get it all to come together, and if it wouldnt cost me an arm and a leg, what do you think, could it be done and if so would you all do it? Im guessing since alot of the work would have to be custom, it would probably cost around 20k or so.. Yes I know I could trade in and get a better car stock for that, but I like to have cutom rides =P

So what do you think? Possible? And if so would you do it?

P.S: The turbo I was thinking of Using would be probably from the Volkswagon Golf GTI or Jetta, whichever one is more readily avaliable, because if I am remmebering correctly, both have 4 cylinder 1.8l models with turbochargers.

I would, because the c55 amg s a HOT car, but I really like the C230. I dont know why, but since its the first benz I ever bought, I really wanna stick with it. Its a nice responsive car with great handling, all it misses performance wise is a little more HP and Torque. I know Benz's arnt performance cars either, but If I am going to show this, I think it would be really cool to show off a c230K with a turbo. Heck, Id even rebadge it to say C230KT. Ultimate custom ride!

Does not seem like its worth the money at all. Youre talkin big bucks, plus say goodbye to that warranty! And when you do sell it... chances are youre going to have to yank all that stuff off, because who the hell would buy that. I know i sure wouldnt, being so bootleg.


Either way, goodluck.

and it won't be as reliable as it was
if you really going to do it, good luck
i would trade in for c55
since they look pretty much the same other than wheels and rear bumper/exhaust

You really think it wouldnt be as reliable? Eh, since i jsut want it to be a show car, i could always put the money into the interior instead.. it just sounded like it would be a fun project and might result in something really awsome.

taking out the charger and replacing it with an intake manifold that doesn't exist is the first thing you have to think about. with the space around the front there is no way to fit a intercooler piping or a larger intecooler. you minus well drop a c32 or c55 motor with all this money.

Actually, if the right amount of passion was there, there's a way to do this . But don't try it yourself.. just wait a little bit.

Not worth it.

Think about this, You would have to get:

-Custom exhaust manifold
-turbo
-bigger fuel injectors
-bigger fuel pump
-some kind of fuel controller
-EGT gauge
-custom intercooler
-custom intercooler plumbing
-boost gauge
-custom oil return lines and coolant lines for the turbo
-A TON of labor
-Tunning on a dyno

With all that said, yea... not really worth the trouble.

How do you like a C230 and not a C55? It's the same car but better (no offense to anybody).

If you think your C230 has good responsive and great handling, wait until you drive a C55!

This is exactly why they created a C230 (performance), C350 (greater-performance) and C55 (ultra-performance)... And in the C55 case, Benz's are performance cars!


So for what you want, just get a C55 - it's just naturally fast, no mods or anything.

I've turboed a few cars, boats and airplanes, www.turbocity.com can help you with all the parts and tech stuff. They help with after market and oem stuff pretty nice people to work with. You can rebuild your own turbo and save big. I still agree with the other guys about the c55 upgrade because I like supercharging much better. Turbo's create lots of heat, and if not set up correctly can be tempremental. Lots of tweeking to get correct. Little things like the exact size and length of the intake tubing can make a big difference. Even the so called kits suck in most cases, and you end up havinf to fine tune waist gates and tubing size. All this is from expierence on several projects. I would go with a Paxton or Vortech supercharger, that would create less heat and work pretty well. Oh and with the engine having more compression you might just blow it up. Most turbo cars run less, then make up the power with the turbo. Anyway, good luck!

Not necessarily. The current SC does 11 1/2 PSI from what I understand. It probably takes about 30-40HP to make make 70-80HP so by replacing the SC with a TURBO, all the cars variables stay the same but you've gained 30-40HP, then add a few lbs of boost, say to 15 PSI, I bet you can get by with that with no other mods, maybe coolr plugs and an FPR that's been tweaked for more pressure. As for the exhaust manifold, that's old school and it's hard. Modern aftermarket turbos are being put downstream in the exhaust between the cat and muffler. Then they route the boost back to the engine. It would seam like you would have bad turbo lag but people that have done it say it's great, very little lag if any. Think about the costs, you can get a reman turbo from a Mits for a few hundred bucks. Attaching it the exhaust requires a muffler shop to make you an adapter and mounting bracket. You'll need some tubing to run the intake to a suitable place and piping to run the boost back to the IC. The tubing doesn't even need any bends, you can do that with hi-temp silicone elbows and hose clamps. I bet you can do it for about 2K in parts and services. They sell a turbo kit one guy developed for the S10 for $1,500 and gets 200HP from the 4 cyl, it's rated 120HP. As for the boost guage, definately get that to tune the wastegate, they run about $15 for a simple one, and $80 or so for an electronic one, the only difference is the expensive one has a remote boost sensor that sends the single through a wire to the gauge, the cheap one sends it via a vacuum hose. As for dyno time, find a sponsor, someone willing to trade dyno time for future development of a kit.

Those turbos that are down under the car are crap. If they were good, everyone would have them. One key to getting the most power out of a turbo is the least distance from the compressor side to the intake manifold. Having 6-7 feet of intercooler piping is not a good thing. Also, using rubber tubing that kinks easy is not a good thing.

I wouldnt like having a turbo exposed under my car. You need oil lines and coolant lines as well as a line from the boost controller to the wastegate actuator. I wouldnt want that stuff exposed to road debree and such.

As for a turbo, yes you can get one for a few hundred bucks. Maybe a 16g or something small.

think about this, you have a mercedes, why would you want to ghetto rig a turbo set up on a mercedes?

I have a friend who put a mutsubishi 20G on his 1997 M3. It was cool for a while but he said it wasnt worth the time and money he put into it. He had so much in that car.

No shop is going to do the tuning for free. There is not a big market for turboing MB cars. It wouldnt be worth their time and money.

I say, keep your car how it is. You will thank me when you go to sell it and dont have to part it out, find the old oem parts and try to sell a tired c230.

excites your girlfriend
normally i would say what was already said, sell the c230, buy a c55, save yourself time and money.

but if u really wanna do something awesome you should drop an E55 engine in the C230 haha. I know it wouldn't fit and all that power would probably destroy the car but it sure would be unique.
that would get u on mag covers!
