Twin Turbo
I have owned a small fleet of Turbocharged sports cars over the last 15 years. The Evo with a DP, full exhaust and tune pick up MUCH more than 20 awhp. Have seen around 380 awhp on the stock turbo... full bolt on car of coarse.
Its no secret that forced induction cars, turbo or supercharged have more potential than an NA car.
I do like the C63, great car.

The c63 is very limited. After a tune and headers, there isn't much you can do besides a supercharger. Unless you milk out every little part like Hagi and swap out for lighter aftermarket parts. My 335xi had lots of options and gets a lot more than 20whp from a tune. Not to mention you can upgrade the turbos and I've seen videos of a 335i with upgraded turbos beating a tuned c63 full bolt-ons.

and he even launched @ 6k RPM and I just WOT'd it with ESP on and kept with a car length..All those c63 vs 335i on youtube are stupid..none of those c63 drivers know how to drive 
which is why in all of those videos the C63 sounds more quite then the 335i (which means the idiots probably left the C63 in coffee mode)I raced a turbo civic the other night and the guy has 340WHP and I smoked him...so unless a upgraded turbo 335i is putting down 500+WHP/Similar TQ (which I highly doubt) then it's gonna be a no go

BMW 335i JB4-RB turbo vs Mercedes Benz C63 - YouTube Never said it beats a c63 supercharged. I said a tuned c63 with headers
RB 335i vs C63 P31 Full bolt ons - YouTube

no way they'd pull my buddies R32 GTR especially my c63 if I'm pulling my friends R32they must be because even a guy in the comments is confused
"wow, nice i was expecting the 335i to loose. I raced a stock C63 the other night and i was just a bit slow with RB's and 50-50mix E85 and 100 octane and 100% meth..."

I havent researched modding a N54 motor but how long will that motor last at 500whp with stock internals compared to a headers tune M156? My money would be that the M156 will be reliable for years.
EDIT: not saying that 335I isnt impressive, thats good power! You can take down stock R35 GTRs with that power all day....

To get into the tens like merc63's car, at our track, I'd be looking at drag wheels and tires, headers, injectors, cam and maybe some headwork on top of what I already mentioned. It's a bit of an ordeal.
