I agree that if you are really looking for 600rwhp then you are looking for more that most have done with the 5.5k motors. You should look up Blackbenz. He has a very fast clk55 with a kleemann blower. Physically your engine bays are almost the same and both have steering gear boxes instead of rack and pinion.
This poses a problem getting the exhaust to flow on the driver's side.
If I was going to try and go down this road I would buy a 5.5l motor and have cast iron sleeves installed and custom pistons and maybe rods. Then an used 5.5k blower and custom intercoolers and etc. Once you had the hardware installed then tune. Maybe some NOS. You could probably do this for around 15 thousand in parts and machine shop costs. Probably another 5,000 in labor or more for the rest. I think that maybe 20-25k would be about right. Then another 5-10,000 in drivetrain improvements to handle this power. I am not one to tell you to spend your money on other things as you can see by what I do.
Give me a shout if you are looking for someone to do the work for you. It would be a fun project.

Don't think I ever did......car is totalled now so I just miss it

Damn, you certainly have the cleanest OEM+ 202 I've seen...job well done, my friend!

I think 500rwhp for a 3400lb car is pretty outrageous and much more obtainable. That's more than twice what a stock C43 in putting down. That should be good for 11's or high tens with DR's.... If you can get all that power to the ground, you'll need an LSD and a major tranny overhaul to hold that kind of power. For me, once you get into this kind of power output, I start asking myself why? Is this just going to be a drag car? Because there are better ways of building one for way less money. Is it going to be a DD and a track car, because that's going to cost you so much money for every 10k miles you put on it.. I guess I just don't under stand why running mid 12's with the 5.4 swap and bolt on's isnt enough? You'll have e92 M3's pi$$ing their pants trying to keep up with you and for under 10k..... Where is project55?

low 13's high 12's and I'm HAPPY!!!! 600 RWHP is just not practical for a DD, like austin said the guy with 550hp drives around 1500 miles a year.

Just realize that everything here is theory (and I use that word loosely since theory should be scientifically supported) and speculation.

You could probably spend 25 to 30 grand and get 600 rwhp that would probably not be the least bit reliable. Cars that are much easier to build with a much larger knowledge base can take that much money to make that kind of power. You have blank space (as in an unknown solution) with no knowledge base (ie people who have done it and know what it takes) and you're trying to fill it and there will be mistakes and miscues that will cost more money.

Trust me, I'm not trying to bust people's bubbles, but there are so many recent threads that go something to the effect of "I want to make 500 (or 600) rear wheel horsepower in my C43, how do I do it?"

Here is my generic answer to all variations of that question: Read, read, and read some more. If you come on and ask that generic question, the best answer is "Send it to Kleemann along with a $20k check and they should be able to get you up around 450 rwhp," because you probably have not acquired the knowledge to do it yourself.

Now if you come on and say "I've looked at a fuel pressure regulator that raises the fuel pressure with boost levels, but I want to find a more accurate means of increasing fuel flow with boost. Is anyone aware of an off the shelf component that alters the MAF signal to accomplish this or uses some other means?" Then hey, look at that, you have a question that is worth discussing. You've showed that you have actually read the threads that exist about adding a supercharger to an M113.

So please, read. There are millions of books, thousands of threads, and tons of Youtube videos that can increase your knowledge. Read and understand. If you don't understand, then ask a specific question. But please, please, please let this be the last "I want to make X-absurd level of horsepower, how do I do it?"

I would recommend that instead on dreaming and thinking up crazy ideas, just get out and DRIVE

I have a 98 C230 that needs an engine. I was planning on dropping in a V8. Probably a Chevy 350 and Manual Trans. I just can't see spending all that money on a M113.....

amgmaster4343

one reason I only drive 1500 to 2500 miles max is becasue my C43k is a toy and I know that the engine will be done by 90k to 100k miles theres 49k on it now. Once you tune a car that high it's a toy period. if you want a DD that has good on MPG and fast, get a street bike.

I agree, I don't even know a E55k with crazee mods making 600rhp. Not happenening unless you turbocharge it.

amg801

you can pull 600hp out of the 43 motor but it would be the same way you would out of any other motor, put a supercharger or turbo on it, build the motor with forged internals, cryoed and nitrided block and crank, extensive head work cams etc and then run like 15 or 20 pounds boost through it im sure you would be hitting some big numbers then. and also get a 2spd powerglide to take the power and you set
