is there anything people have done to prevent there headder from cracking?
ive read a quabillion post of there headder cracking with there kits?
will a better header fir on there kit?

 

ye cast iron.

maybe try wraping it with exhaust wrap???

 

do they make a cast mani for the t67 kit

 

if that t67 is t3, Revhard makes a nice cast mani for a very good price. theres a thread where buschur said its the same as a turbonetics mani and he makes the 02 housing to make it bolt on in conjuction with that mani. I see revhard mani on ebay sometimes for around 250.

 

have a shop(if you can't yourself)weld some support bars from flange to flange(underneath runners) to take some of the turbo weight stress off of the tubes. i've had success on other cars with this method.

 

thats what i was thinking
i dont own the kit i was jus looking at one

 

Support bars a good idea, but a turbo header gets beat on from the weight of the turbo.

 

Custom brace time!

 

there's a couple of guys who said they think it also is caused by the flexing of the motor and stuff

those guys think that if you add a flex pipe to the downpipe it can solve the issue as well

if i was to pick up a Greddy Kit.. i'd personally do both

 

I have had the Greddy header for years and it only started to crack in its 3rd or 4th year but a custom brace from the turbo to the block will totally help eliminate that issue...

 

Greddy T67 turbos are TD06 based. Greddy has been using the T67 monicker since the early 90's.

Investigate the alledged cracking some more.
Where are the cracks occuring? On the welds or somewhere else?
Do the users have a flex pipe installed?
Is there a brace to secure the turbo to the block? Vibrations kill turbular manifolds.

Do not warp the manifold because it will speed up the cracking process. Get the manifold ceramic coated instead.
