I think Mark has a good point about the possible lack of support for the turbo weight.

Just "bolting" it doesn't automatically mean that the weight of the turbo is not on the header.

There is a reason why I plan to stick with stock headers.

 

The header does not need any support. A properly built header can support a TON of weight. The failure can be contributed to a couple of issues related to the build quality of the header. For what it is worth, our Supra T6 Kits have turbos alone which weigh over 70lbs and that does not even include the additional piping the header is supporting.

 

The Header splitting and the Wastegate Actuator bolt breaking could be one in the same. If the Header hit the bolt hard enough when it broke that could cause it.

I have had third part headers on my car for ages with no issues. Not AP though. Mine were a lot more economical.

SWR.

 

Everything breaks. Even my own header broke and I didn't make it. It just happens. And usually it's from extreme situations like huge turbos Improper installation support. I made a mistake myself.
With that said, Stock Porsche turbo hangers are their for a reason so use it.
Like I said before that strapping on dynos and or towing straps to hit te headers especially onses with external wgs. Also bottoming out into or out of driveways and ur done. Seen it all.

 

I've never put my car on a dyno and never track it.

I brought more pics .. It may help to know ..

 

What do u think ?? .. welding or material ?

 

We dont make wastegate kits so no idea about that.

This would be the first time I have ever seen a header do this. If you bought it from us and it is within the warranty period, I can replace it.

 

The material is too thin and the welds do not have enough penetration.

 

Everything breaks... but there is a difference of a header breaking from a product defect versus user error.

 

Warranty is great for wear and tear. If the part is defective then I believe there is by law a ten year warranty.

I don't believe anyone should be jumping to conclusions. A weld defect or the use of the wrong filler material can be easily determined.

 

I disagree with the "everything breaks" statement. Everything may wear out, but break is something entirely different.

Metal fatigue, yes over the specific metals usage and time. A proper full penetration weld made with the proper filler metal is stronger than the parent metal. Application also comes into play, however the designer/manufacturer must provide installation instructions for the specific application.

If the weld fractured my guess without looking at the part is defective weld or improper filler metal being utilized. I use to hold through my company ASME A,R,S,U and PP Code stamps so this isn't really something new.

 

I agree completely! I was simply responding to Markski's statement of it being possible for anything to break under the wrong circumstances.

 

back from vacation... was typing on Iphone form overseas...
all I meant was that I have seen top rated companies that produce various products from "bad ***" turbos to high end exhausts fail from both user error and or fabrication error... it happened to me at least twice... Even F1 brakes fail when they shouldn't for example...
I have learned a few lessons along the way as well... something that works on a K16 turbo may not work as well on a GT35r with external Wgs...
just my opinion...

 

welding not deep enough.

 

I took this header from ysf g35 ( 6 speeder ) when he upgrade his package from u. He is the original buyer and dunno about the warranty period. Plus u know how much i would pay to ship it back then i have to pay again to ship another one. u know it will not be that much easy AND it will cost A LOT for me. So ,, Stock 997 header would be fine for now.

APPRECIATES.
