hi guys!

so, i need to port my wastegate on my FC3S 87 S4...

i have ordered the gasket from turbo to manifold, turbo to downpipe and also the gaskets from the oil-tubes...

do i need other gaskets too?

and, which diameter should i go? what's the biggest possible wastegate size...
and how to do it right? only take a good driller and drill the hole bigger?

anything to keep an eye on install/uninstall?

thx 4 input!
