If your using SS304, be ready for more cracks. Main reason why we stopped using 304. Just ask the Supra guys. Cracked headers are pretty common if you drive it on the street with 304. Make sure you have the turbo braced, that will help with some stress.

There is only one long term solution..
These are a different... 4-1 style etc... That is'nt the point.. Its the double slip joint...
http://www.burnsstainless.com/MergeC...ollectors.html
The best tubular turbo manifold will eventually crack wo slip joints.
Its like expansion joints in concrete..
Basicaly brace the turbo to the block supporting its weight completely then have slip joints in the tubular manifold for room to expand and contract. A log mani needs them on each runner where it meets the log just as a 4-1 needs them where the runners meet the collector...

Heavy wall construction (.083 or thicker) is the best choice if the turbo must be supported only by the manifolds. 304 or better is also a must, mild steel has a much lower tolerance to heat cracking even if coated. Bellows/flex joints should be used to isolate heat expansion and vibration from the manifolds.
Pretty much every Supra manifold I've seen supports the turbo from the manifold alone. What seems to kill them are the excessively long runners they use. Even with heavy wall tube the extreme amount of leverage placed on the runners off the head will crack sooner or later. In that situation either add some support off the frame rails or gusset the tubes out of the head.
Just some of my experience as a turbo manifold fabricator. Most people don't want to spend the money on a well designed SS manifold with individual runners but instead deal with cracking crap designs that are nothing but a headache and kill performance.
yup get used to it, just dnt nget them coated, cause its heck to weld on when you have to fix it
sounds like Brian needs to pick up a tig soon (heres your excuse)
like everyone said its pretty much in the log design, glad im switching to cast manafolds now.
