Thanks Wessty, Kijiji was on my 'round 'tuit list.
Contestant #1 has a mystery turbo (I haven't found any references to a K11) but has the manifold for it (and maybe the downpipe. He's willing to play Let's Make a Deal.
Realistically how much work am I looking at to pull the manifold if he's got a downpipe for this thing? Am I going to spend a weekend with a torch and extractor trying to pull snapped off bolts and studs out of the head?
Contestant #2 seems to have a K03, and the price is good, but no answer yet (and the ad's a month old... so it may be gone).
Contestant #3... well, if I thought I could do it without my wife killing me, I'd go for it. Sounds like a deal. Unfortunately, I haven't got a garage or shed to store the thing in, and there's a real possibility of us moving in the near future. So... sigh.
Waiting for Contestant #4 to get back to me to see if he's asking $100 each for the bits (what I think he means) or $100 for the lot (which would be a major score, and I could manage to sneak past the wife).
I've also got a couple of positive leads from local wreckers.
Further bulletins as events warrant.
