My car can be the Guinea pig!

I have a 03 e500 with about 160,000 miles on the dash. Do alot of highway driving, back and fourth to Miami. With this amount of mileage i would assume the motor has seen better days. Engine still runs great tho. Would I have to do a complete rebuild of the internals to strap a kit like this on it? Or do I just run it till it blows?! Rebuilding internals would'nt be a prob I have wis/asra step by step... Thanx

Test compression in all cylinders....chances are you don't want to add forced induction to such a high mileage engine. Especially to a motor that's NA to begin with. Build her for boost and it's all good.

I agree with checking the engine compression/leakdown. Your mileage is up there but not horrible. Most NA cars can run 4-6 psi without a whole lot done. A tune would likely be good enough. A small amount of boost on such large displacement would yield good gains. As always, adding gauges for boost, fuel pressure, EGT and wideband will keep you in the safe zone. I would do it in stock compression to start with then go to thicker head gaskets if things last. Then motor internals. If you are prepared to do internals anyway, I would wait till I blow up my stuff first and just be prepared to build. Unless u have a bunch of $$$ sitting around to do everything at once!

BuiltnBoostedZ

Good advise. Just gotta be careful. Put a rod through the block and you wont be able to use it for the build.

turbo97se

LOL .. .you are right of course! I thought about it right after posting ... thought about adding that too ... but it is pretty extreme if you window your block. I ran an NA car for years on 12 psi and the engine wouldn't blow up ... so I just swapped a different (bigger displacement) engine in and built the motor at the same time.

Any updates on the TT kit? I want to see someone do this

MBfinatic

I also would like to see this done but of course for the N/A M113's! We need BOOOST!

Would this same Kit work on an E550 4matic ?

This won't be the same as the supercharged V8, the supercharger gives the M113 Kompressor engines their character. As much as I like twin turbo and how bigger the power gains can be I would still pass on this even if it was cheap. To me getting a GT-R and just modding that or even a B5 RS4 would be more feasible. Great project though I still would love to see how it goes. For me though I'm waiting for the evosport cooling mod to be tested and priced before beginning any mods the 55. Stock for now and still awesome

Brian420

Ok, so a rebuild would prob be the better option. My engine is the 5.0 liter m113 engine and not the 5.5 liter e55 motor. From what I understand my engine has a shorter stroke than the 5.5 . (And smaller pistons I believe although I may be wrong) I can get a e55 5.5 liter motor with 40,000 miles for about 7,000 delivered. Is it worth me rebuilding my original 5.0 motor and then droping the kit on it? Or get the 5.5 and slap the kit on it without rebuilding it? I been debating this for a while now even before this kit was offered, I was gonna do twin rear mounts. Anyone know how much a complete engine rebuild would be for a m113?? Maybe better cranks,pistons, rods etc?

$7k for E55 motor + TTkit = a ton of $$$ ... rebuilding your current 5.0 + TTkit = $$$$$

Not to mention the PITA a TT kit will be to dial in--- and dont forget about the trannie --

too much money and headache -- just throw a v12 TT into that E500

AMG_RL

yea because that's so much simpler.

Brian420

Yea wonder if the 6.3 liter would fit off the new e63's.. But again is 500 horse really enough to not get bored of?! How many horse is the v12 and would it fit the 211? How much can I sell the current motor I have for etc..

AMG_RL

Search is your friend, but in short:

This is my advice and take it for what it is, but you will be doing your self in by upgrading your 500 to a 55k, and spend a **** load of time and money on it, when you can just get the real thing form the get go.

You have the engine, the supercharger and all the cooling, intake, TB, wiring electrics TCU/ ECU, esp, trans, brakes, suspension, exhuest, cats and on and on.

Save your self the time and the money I say and do not try and reinvent the wheel. Its there & relatively cheap!

its also a much better platform to add on, for when you want more

Forget putting a 6.3 (6.2 in actual fact) in the E500, the electronics will rape you. I'd imagine putting the M113 Kompressor is easier because it's the same family of engines. Not sure if the ECU will work on the 55k motor though. People have swapped 4.3s for 5.4s in the C AMGs using the same ECU so maybe it would be possible. As for the V12, I think you need a good shop, a large wallet and patience. The V12 will get larger HP gains and be a better 1/4 mile car but for some reason I don't see that engine in that car. It's still awesome. So either sell the E500 and get something you want or do a 55k swap.

The M113 supercharger kits on the market, from the venerable specialists are a better, proven solution.

You don't need boost per se, you need faster denser air at the least boost and temperature possible.

That's why people want to move turbos out of the engine compartment. Turbos thrive on heat whereas the rest of a petrol engine doesn't. That's why turbos work well in a diesel environment.

Fuel dragsters use superchargers, not turbos. Yes, they isolate their cooling tanks for best results like some of the OP on the Forum with tanks in the trunk.

grane

good advice.

Brian420

Yea might jus keep the 500 and get a 55. I put so much work into my car cause its my first benz and was paid for cash at auction. I have a c-class that I am currently building my credit with. I'm only 24 and jus started building my credit last year... The 500 already cost me over 25K. Replacing airmatic struts,transmission, and almost every part u can think of! Did most the work myself except the tranny. Before I had the ***** to do the airmatic myself, I spent 7k jus to get the front struts replaced at the stealership! Maybe around 6k but still I changed the front left strut myself recently in less than 15 mins a side! They charged me for hours of labor and etc. So if you guys were buyin a new E would u get the 55 or 63? I here people dont like the 7-speed tranny in the 63. The 55 has hella mods compared to the 63 from what I understand.. What to do?

MBfinatic

I was already checking STS kits but I would rather see if done by speedriven were its tested before hand. I would much rather use a turbo kit over a supercharger kit. They could possibly cost less and be way more efficient. The best C55K did about 482whp and the (only) C55TT did about 820+hp and 930+tq however I do not know the whp on the TT project. I do know it was running low tens.

msheredy

EGTs on a gas engine are much higher then that of a diesel. The reason turbos work well in diesels is because they don't have the RPM to spin a supercharger efficiently. Turbo's don't rely on crank RPM so they can create more airflow at lower RPMs.

They don't because they can't. It's in the NHRA rule book. They probably wouldn't want to either. I could just see the turbine housings becoming grenades!

grane

Thanks for correcting me on the details.

Do any NHRA dragsters run turbos? If not, why not?

gaspam

"top dragster" and "comp" category allow turbos in NHRA

guysandiego

thanks - i wondered why dont ALL those dragsters run turbo set-ups

guysandiego

i wasnt trying to indicate it would be a simplier project--

i was trying to illustrate how silly, expensive and difficult the other options are, doing such a huge project on an E500 -- they may as well go all the way and throw a v12 TT into the mix of options---

but-- it would probably be cheaper to just sell the E500 and buy an E55 then Mod it.

My mistake was responding to the dreamer who posted the thought '2 posts' --- I should have known better
