Has anyone one hard lined their wastegate or boost controller? I'm thinking of going in this direction, and wanted to get input and possibly tools and parts list.

Back in the day at Gotham, a car came in with a fragged motor b/c his w/g and b/c lines were hardlined. They had zero slack/give to them, so one of them eventually cracked, leading to lots o boost and even more detonation

stainless will be easier to deal with.

Notice that the factory oil return lines for the turbos are hard lines, but they have flex joints in them?

I imagine more motors are lost due to lines melting, splitting or blowing off then the number motors that get FUBAR'd from a proper hardlined setup.

vacuum hose and/or stainless steel line with DEI fire sleeving over them is the reliable ticket in my experience Jules

I used tube nuts and got new banjo fittings with a -4 instead of the barbed end and used hard lines to get up the side and away from the heat, then used a bubble flare and silicone vacuum line to allow flexing.

Saw this CYM at Sevenstock w/ hardlined Wastegates.

I use AN hose with screw-type hose clamps. yeah it's kind of ghetto (not that noticeable though) but it's faster to install, cheaper than buying all those fittings, and just as reliable.

i doubt i'd ever consider hardline hoses. too expensive for something that isn't really needed, imo.

there's nothing wrong with using a good quality rubber hose.

Hardlines look great on a show car/trailer queen, but for an FD that actually sees the road and all the accompanying vibrations, bouncing and jouncing that comes with it you definitely need some slack.

Well, I personally know of one very talented track FD guy that melted a few wastegate lines. He wound up hardlining them and the issue went away. For street use, the regular sleeves are probably enough for most people. For all out track usage, a PROPERLY fixtured hard line setup might be beneficial. I would think it would depend on usage and implementation.

I was constantly melting lines on my external wastegate. I switched over to copper lines and they have been working great ever since. Cheap and easy. Braided stainless would be nicer though.

I had my wastegate hardlined... i'll take pics this afternoon and post em up..

As mentioned, the typical problem with hard lines is that they are rigid enough to vibrate harmonically (like a tuning fork) due to engine vibrations, etc., if not supported properly. Vibration can cause them to crack, usually at the stress concentration caused by fittings. So, IMO, careful attention to mounting or at least some small amount of soft tubing is required at tubing ends, etc., to eliminate this potential problem.

^ picture above with hard wastegate lines is Tim's (RCCAZ1) car it's a very sexy beast.
