I've seen some of the recent posts regarding the autosquare turbo manifold, but I'm curious if anyone has any actual side-by-side comparisons between the Autosquare and Treadstone manifolds.

Obviously the design is the same, but are Treadstones claims that the competition is a cheap knock off true? Has anyone actually handled both of these manifolds off the car to compare actual weights and cast quality?

Im hanging a HX40 w/ bullseye power turbine off this manifold, so a large, heavy turbo -- so I do not mind paying more for the manifold less likely to crack down the road, but if the manifolds are truely identical, why spend more than I have to.

Thanks,
 
In case someone else here is looking for someone who has handled both, I got this from a member of another forum:

From another forum:

hey ryan i saw ## post during lunch but didnt get a chance to post...

ive had both side by side, and had my father review the castings of both...

he said just by looks, the treadstone is a pressure cast, where as the autosquare is just a sand gravity cast.. he said both serve their purposes, but the pressure "should" hold up longer pending correct sand and equipment is used...

as for weight the treadstone was heavier not by much however...

keep in mind even though the treadstones are sold out of florida, their manufactured in brazil... but on a good side note ive heard some "tuner" forums talking about brazil manufacturing a lot of turbo manifolds for a lot of platforms... my dad never heard of it, but u never know...

i went with the treadstone myself, and a tial 38mm... if the treadstone cant hold up ## turbo, idk ### im gonna do about my 35r...

the only thing i did to help myself out, with cracking, is i had the whole thing dipped and coated... im crossing my fingers to its durability myself... time will tell


If anyone else has any other 1st hand info, it would of course be appreciated. I have already ordered a treadstone manifold to replace my previous hahn setup though.
