just out of sheer curiosity (not because im planning in any way to do this) but do you think with the kits and mods currently available for the c230k you could build the engine up enough to produce 300+ hp? i know some of the rice burners can do it but prob with a ton of turbo boost, by the way could you add a turbo to this engine? again, all curiosity i wonder if anyone has tried something like this yet, or is everyone just waiting for the c32 coupe?
comments?

 

tuning the coupe engine to 300+ hp would definately be a cost restrictive enterprise not that it isnt doable, the dificculty arises do the the limited availability of tuning products.

for example: renntech offers a tuning package:

2.5L Displacement Increase,Ported and Polished Intake/Exhaust Ports, Hi Performance Cams, Larger Crankshaft Pulley Kit,Hi Performance Exhaust, Larger Intercooler And Piping, Modified Computer,Renntech Air Filters $18,950
BHP Gain 80, Total BHP@RPM 272@5800, Total Lbs.-Ft 285@2800 - 5100 rpm

pretty wild, but still not 300 hp.... slap nos on and your engine might go boom, or might break 300hp, but at what cost??? about 20k your better off waiting till some one totals a c32, buying the wreck, and salvaging the engine. I imagine a wrecked c32 (actually just the engine), labor, and tranny modifications would cost around the same as the renntech kit, and if AMG can cram the v6 kompressor engine into the coupe, so can you.

i dont think you can turbo a supercharged car, and if you can it doesnt make any sense, since both turbo and SC are forced induction systems.... your prolly better of replacing the blower, but again you need to have one made, or something comparable difficult.

limited availability of cars, low production numbers, and low demand for tuning parts, makes tuning a car harder, and more expensive. if you want a car to endlessly tweak to hi performance standards, you better have a nice bank roll or your in trouble

 

Actually someone on this board is doing that right now. They shall remain nameless, but they are going to put a C32 motor in a coupe and mod it out pretty good, or leave the motor in it and replace the supercharger with a turbo. It should be fun to see what happens.

 

while a c32 engine swap has crossed my mind on several occasions, and the revelation of c 32 coupe is promising, the technical know how and available resources are for this kinda project are outta my league.

I use my 230 as a daily driver, i dont want to rent a saturn for 2 months while my car is fitted with a new engine.... let alone search for a shop to do it. Oh yea, not like you can walk into a pepboys "I will take one c32 kompressor engine, and some meguires spot detailer, ok?"

 

I agree with greg230, if you want 300 + Hp it would cost you tooo much. I am not saying you can't do it, if you have the $$$ cash to play with anything is possiable.

But if you want a quick fix to this problem just get a 75 - 100 HP Nitrous kit then your there. But at what Cost?

 

yeah i thought it would be expensive- waiting for a c32 is the way to go. by the way iceman i wouldnt want nitrous i want the power there all the time not just when i spray.... hehe

 

I think for way less than that you can shoehorn a 426 Daimler-Chrysler Hemi crate motor for under $11,000 good for 465 hp or a chevy LS1 small block for under $5,000 good for 300-350 hp. Then you would have a realiable motor instead of trying to make a little motor work way harder than it was intended to.

I remember seeing a Porsche 944 with a small-block Chevy engine at some point. I don't remember the details, though.

 

thanks but no thanks. installing an american motor defeats the whole reason of getting a german car- you wouldnt put hubcaps on a ferrari, right?
lol i love good old displacement tho

 

It's all the same company, Daimler-Chrysler!

 

If your really going for a big HP engine I'm sure that Renntech would sell you a Custom CL 63 engine for around $30,000 lol

 

But when you think about it, if you were going to spend $10,000 upgrading the engine why not sell your car and get a C32, SLK32, or an M3? Or if you really want to go fast look in autotrader and get a 98-02 Z28 or a Mustang Cobra and put a blower on it from ATi tech, and I am VERY confident you could run 11's. All for under $22,000

 

i would think if one was serious about going fast, i would look into upgrading the supercharger it self. i was looking at eaton's site, and it looks like the m62 supercharger would fit in the same application as the stock m45 super charger. the m62 will supply 25% more air volume at the same engine speed. then you may still be able to use the engine pulley of choice for further increases in boost. i realize that this is only the start, but it may be fun

 

yeah but i dont think that hemi's are made in germany buellwinkle hehehe

 

If using an m62 Eaton Supercharger, it would be even more simple to increase the boost. Just change the pulley on the supercharger instead of the crank.

I don't know how much power the stock internals on the C230K can handle, but some forged rod's and lower compression pistons might be required.

I don't think 300hp is all that hard to get. I think the hardest part would be finding the parts to put on. Mercedes doesn't have the aftermarket support like a Honda would have.

 

I think KJ-TypeR is right, finding performance parts is the hard part, doesn't seem like theres much out there, and whatever is out there is kinda pricey.

 

The m62 would have a few problems:

1) The intake I believe has the same exact dimensions but not the compressed output side. New mounting bracket and intercooler tubing would be needed.
2) The overall dimensions and mass of the unit are different which means you have to take that into account when creating the mounting bracket. Remember the engine acts as an oscillating body changing a part that is attached to the block as big as the supercharger will change the resonant frequency of the body as a whole which may be felt as unacceptable vibration in the vehicle.
3) The m62 steals an additional 10 to 12 horsepower at its peak rpm when compared to the m45. You'd either have to live with that or overcome it by lightening the driveshaft and flywheel. Those last two choices would change the driving characterisitics of the engine.
4) You would have to make sure the fuel subsystem (injectors, pump, ecu) can all cope with the additional 25% air flow.
5) While you are here you might as well lighten and strengthen the internals. You might be able to get max rpm up to 7000. Also if you lighten the internals proportianately to the driveshaft components and the pulleys you might not affect the resonant properties of the engine.

All in all it sounds like a fun project, definitely expensive, definitely time consuming but IMHO you could get 300 to 325 HP out of the engine.

 

Nobody does cheap large iron like americans. Would it make you feel better about putting an american engine in the car if you knew your car was made in Brazil?


And Timmy, a Z28 or Cobra would be fast and better cars but it's not why I got a Mercedes, I got it for the free car washes and 4 years free maintenance. So until Ford and GM start giving me free car washes and maintenance I'm gonna drive one of these foreign jobs.

 

I’ve looked into the M62 supercharger I think the best way to go would be to remove the supercharger completely and mounting a turbo to get to that 300 + figure. Running the same boost you will pick up 30 - 40 hp just in the paralytic loss from the supercharger.

Renntech made a 325 HP slk using a supercharger and a turbo that is really pushing the 4 cyl . I’m having a new engine built a bored and stroked 3.8 twin turbo it should be ready by the end of Aug depending on my cash flow . Mercedes parts are really expensive. A set of rods and pistons run $2400.00 (6). It should be able to produce 475 hp or more. We will have to wait and see.

please don't tell me you just said 475HP!!!

um, i think a road trip to jacksonville is called for in sept...

 

i dont think that will fit, but it would be a fun ride if it did

the big advantage of dropping in a supercharged v6 from the c32 is how little "other" modifications you may need. maybe upgrade some of the tranny parts, but other then that it shouldnt be as difficult as totally rebuilding the existing engine to generate power.

 

is that engine for you, and is it going in your c?

 

i was about to ask the same thing, is it for your car??

 

475hp???? is there any part of the c230 driveterrain that can handle that amount of power? i mean i wouldn't think that the rearend or the transmission was designed with that much excess strength, but if it was, that would mean that it is near bullet proof in mild builds.

 

Turbocharge and Supercharge can work together. The supercharger works at low rpm to increase torque while it can reduce turbo lag. The turbocharge works at mid to high rpm to produce high horsepower. Again, you must have tons of cash and a bullet proof engine block.
