I have been doing some research and came across this ebay auction http://cgi.ebay.com/ebaymotors...56616 and it says that it is made from tubular steel and that cast iron isn't good. I thought most manifolds where made of cast iron because it was better. Anyone want to clarify this for me?

Thanks,

if you purchase that manifold, prepare to repair the cracking problems they are prone to.

 

I'd rather have cast iron. But I dont.

BTW... aren't most turbine housings cast iron?.. except for some of the big dollar ones which may be cast stainless steel or something.

People rarely have problems with their turbine housings falling apart, and those things get hot.

 

those things are terrible to be honest. the metal is 16 guage and cracks really bad at every weld from looking at my friends.

 

Mine is made out of wood, no problems yet. Steel is fine, if its a high quality...that looks like it will crack at any decent amount of boost. Cast is strong!!
