... you all know you can add anything you want to this car right this second... its just about money... if you wanted to drop a v8 in here you can... there is room... Startech did it... everyone complains about how "you can't add anything" ... you can add a Twin Turbo to this... you could add a supercharger as we speak! ... its just about money and effort... you might have to replace a ton of things... but you can do it right now!

ECU has been remapped... Borla has been put on hold a million times over now...

If you wanted to add 6psi to this engine... without forging pistons that might be risky... but you can easily add a super charger + cooler with a smaller pulley and not worry about blowing this car up... hell just add a small sea shell turbo in there... and run low PSI... im sure around 3 - 4 psi boost can add at least 20hp at the least....

and if you want headers... doesnt the AMG version of the SLK32 have them... im pretty sure they have the same frame setup... you could just bolt the new ones on....
