On a serious note...
I know a few people who have highly tuned engines... one or two of them have rough idling.. becasue the engine is tuned that much (more for race\rally than road use though)
If I were you Kai, I'd stop and think, what do I want from this engine? if its out and out performance, then I would sell the 180 and pick up an EVO or something... If your intent on keeping the 180 and you want huge performance for minimal outgoings then sell the KV6 engine and stick a T Series turbo (easier and cheaper to modify) into it... or an Audi twin turbo lump.
Unless you are willing to uprate internals in the KV6 I don't think it will go higher than about 230 ish reliably... Although you could allways speak to QED who at one time were running a KV6 at 300 odd brake...
