Ime andy aka "neviu".
ive got an w126 500 sec koenig specials whit a custom twin turbo setup.
we used an 560 engine block whit 9.0 compression, we used our custom efi kit, made an custom intake manifold whit laminova intercooler cores. we used 2x turbos from turbobandits.
everything on the engine is custom work thats created by us in house.
Hendrik and me, are building pretty much anything mercedes related, other cars to.
we have an m119 efi kit. and pherhaps when theres intress we can develop headers, supercharger kits/turbo kits. or other kind of performance parts that people whant for there 500e.
we are open minded and like to create the impossible on these old engines.
if theres any question you can always ask us.
heres some pictures of stuff.
