Has anyone upgraded turbos?
There are other OEM upgrade options as well that no one has explored yet. The AMG GTR uses the same turbos as the GT and C63S, but has a larger upgraded compressor wheel. That would be a direct bolt-on as well, and you could use your stock manifolds since it's not a twin-scroll unit like with the E63S.

I hear you but i'm with this guy, https://mbworld.org/forums/c63-c63s-...ml#post7024922
Its more then just the turbo bolt on difference, the inlet is different since its directing the flow directly do different cyclinders so there would be more parts involved then just the turbo bro. Thats way it may get costly instead of just doing a larger turbo upgrade. Again i don't know the difference in parts/pricing but surely interested in a twin scroll setup for our c63s.

Fact: the E63S manifolds bolt on to the C63S cylinder head because (wait for it...), they have the same cylinder heads! The turbochargers are only different in that the turbine exhaust housing and flange are cast for the larger twin-scroll. Power-technik has already mated up the manifolds on his C63S, so it's not even a question if they bolt-on. And yes, I know he's using aftermarket Borg Warner turbochargers with a custom flange welded to the manifolds...

, I'm not a turbo guy yet, I've always been a routes style blower force induction power guy. When i heard the explaination of a scroll I though it had to do with directing airflow differently (different type of flow path of heads/intake etc...) So your saying its just a turbo difference and they mount the same if thats the case this is damn good news.

I'd so rather have an upgraded turbo then tune even with the stock exhaust would be ideal setup for the c63s as a major sleeper.
Sign me up!
good explaination http://www.audiboost.com/content.php...-turbochargers
EDIT:
Below is what confuses me on this conversation since it shows the header having separate porting for a twin scroll turbo setup. So what your saing is the header is the same on the c63s and the E63s? I'm assuming not, so that would need to be another parts to be purchased assuming that fit as well. This is why I'm assuming its safe to say its just easier to purchase an upgraded turbo then to switch to twin scroll. BTW i do believe you that the turbo would mount up but they exhaust flow would be different if the headers are different which we both know are and what I was trying to explain. The kit would need headers and turbo (twin scroll) not just the turbo was what i was stating. Yes my wording was incorrect when saying directing airflow when i meant header. We actually are on the same page just didn't get there at the same time ;-)

Twin-Scroll Design
Exhaust passages from two cylinders at a time run
separately from each other in the exhaust manifold
and housing. They are joined just before
the turbine, preventing reciprocal interference of
exhaust fl ows. This guarantees a rapid buildup of
torque and outstanding response
lastly on this subject have a strong feeling the C63s would loss its exhaust rumble with a twin scroll turbo setup.

The firing order is the same on the M177, so the E63S manifold is taking advantage of the exhaust gas pulses to spool up the twin-scroll turbine. Nothing special is done other than splitting the manifold runners - so it would still work on a C63S. I doubt there will be much difference in sound, especially if you keep the stock DPs and exhaust.
The twin scroll setup is already proven to make 725 HP on just a tune - I would imagine 750 HP or more with additional mods (catless DPs, exhaust, etc). It's a very potent setup, though I still think a GTR turbo would be cheaper, easier, and still make good power (we'll see once deliveries start and tuners get their hands on one to see what power they make with tune only)
What's involved in tranny Upgrade, does it need to get sent out?
Agree most shouldn't be as worried about the motor since merc builds them pretty damn stout and this one is boosted. Believe heat and cooling would be more of an issue regarding engine staying together.




While Weistec's Stage 4 seems to give the highest HP increase available on the market: http://weistec.com/all/mercedes-benz...rade-m177.html (I don't consider GAD Motors to be an upgrade; it's practically a full rebuild, and costs likely upward of $20K), I think Pure Turbos Stage 2 seems to be the best bang for your buck (if not the best bang, period). And with their Black Friday sale currently going on, I think I'm about to pull the trigger... https://www.pureturbos.com/store/mer...rbos-1145.html
My one consolation with this setup is, it made the figures posted on their dyno (750rwhp and somewhere around 685 ft-lb, by eyeballing the dyno sheet, as it's too small to read) on race gas. So as long as I stay on 93 pump, trans should be well within its torque rating.

Maybe your experience has been different than mine. Maybe he's a super nice guy. But my experience wasn't very fruitful, even though I was waving $$ in his face to get the setup he talked about.
Maybe you can elaborate more on his setup?
