Title: Exhaust manifold studs
Post by: Kriss on January 16, 2012, 10:57:48 PM
Hi guys

I\'m trying to putting back my long block, but I\'m struck in the forst step: putting up turbos... :(

When I take out the engine about 1 and 1/2 year ago, 1 of the exhaust manifold to turbo studs broke, and only recently I manage to take it out completely.
Now I have a bunch of studs and 1 long bolt, I can\'t figure how how many studs I need, the parts diagram say are need 5 stud of a type and 1 stud of another, but I have 8 holes... and also the long bolt you can see in the pics...

Someone help me please!!!
I will take them from Atkins Rotary (http://atkinsrotary.com/store/home.php?cat=807 (http://atkinsrotary.com/store/home.php?cat=807)), but don\'t know which one to order... :(

Have you got the Lower Intake manifold on yet.

so four of the ones pictured for housing to manifold

I think there are 6 of the same from manifold to turbo. With two of the longer bolts in the middle holding a gasket and plate onto the turbos and into manifold, there are two smaller ones for the same plate aswell.
Then four for the down pipe

No, the manifolod is down, and the studs on the housing are up.

Ok, let\'s say that from manifold to turbo and from turbo to down pipe, we have 2 kinds of studs: big ones (circled in red) and small ones (circled in blue).
I need to know how many of each one are needed in the 2 section.
