bolt and stud question
 

I have searched the site but can not find the info I need, What I came across all says upgrade the stock bolts to a grade 8, but if one don’t have the stock bolts how are they suppose to know what size to get?.... so here is my question….
I picked up a used greddy kit with very little hardware, I have 4 turbo to turbo manifold bolts (8.8) but that is it.
My question is what size should I get for the 4 turbo to downpipe bolts? Same as the 4 I have for the turbo to turbo manifold?
Do I need any nuts or washers?
For the turbo manifold to the block do I just use the stock components for mounting? I see it is recommended to upgrade these studs also… (order from FM, I believe I read) , but because of time constraints I would like to go with stock components if possible.

Sorry for the noob questions I just cant find the info I was looking for by searching. Thanks for the help

I have four 8.8 grade studs and 4 stover nuts that will fit the Greddt kit.

PM me for details.

I used the stock stuff for the manifold to head. It has been apart quite a few times with no problems. Upgrade the rest.

I used Socket Head Cap Screws for a tidy look and just cut down an allen key for tightening those hard to access ones mounting turbo to manifold.
