I was browsing Ebay as i so regularly do and i stumbled across what seems to be a pile of welding spaghetti that somehow attaches to a turbo and wastegate and even a screamer pipe...
A lot of effort there to get certain runner lengths and a specific turbo mounting position. It's just an upside down version of what most brand name high mount single manifolds are like - instead of being setup for show, it's setup for practicality. Steampipe is also more attractive to me than the bling brittle stainless manifolds.

Looks cool, ++ for the effort. I wonder if it works well Would be good for a single conversion for around that price. Am i correct Emanuel? If it flows as well it should im thinking it would be fine.

James its not allways about it looking beutifull to work. judging by the amount of time spent designing the almost equal length runners id say it looks good.its also in my book better than high mount turbo setup due to the heat factor. i would dare say that setup would work best in the top end of the rev scale due to the length of the runners.
go check out some log manifolds compared to this one and see which one is crap.

Cihan just look at the std soarer exhaust manifolds theye are very small and short. the reason being is to get the exhaust gases as fast as possible into the turbine to generate boost as quickly as possible. with longer exhaust runners like the one in ebay it would take longer for exhaust gases to enter the turbine so it would be making boost higher in the rev range.
Making boost higher in the rev range is a given for virtually any single turbo conversion on a 1JZ as more top end would be the only logical reason for that costly move and the associated extra lag and reduced powerband seems to be accepted by those making the move. Used twin stock turbos or even new hiflows from Neil would be cheaper than a single conversion for failure replacement and would still provide the early response the engines are renown for - and good for sub-12 second quarters as we know
