I am in the process of putting a ported manifold and 9 turbo onto my 8. I would like to keep the stock 8 turbo/manifold/o2 housing together in case i need to throw it back on. What are the bolt sizes for the manifold to turbo and turbo to O2 housing? The turbo still has the 2 studs from the inlet to the manifold and 2 studs from the outlet to the O2 housing. I want to try to get this put together this week still so i don't want to wait weeks for the dealer to get them in, haha. Thanks for any help!

 

umm not sure of the thread size but the head sizes are 14's if i remember correctly pretty sure thats what they are

 

I think you are right, however, that doesn't help me at all, lol.

 

m10x1.25 is the thread size for the bolts that go from the exhaust mani to the turbo. If I can find one I will measure it and post I just can't remeber lenght off the top of my head.

 

Cool, thanks. I can go out there tonight and measure them too, i was hopeing i could get the measurements so i could order them from McMaster so they could ship today.

 

Get factory ones and the cone washers, cheap non-exhaust grade bolts WILL NOT stay put or last.

 

Yeah, thats kind of what i'm thinking, I just don't want to wait for the dealership, haha. Any other sources that have these in stock?

 

Check fastenall and make sure they are the correct material and hardness also. This is really something you don't want breaking, but if I remember correctly most of these bolts are ~$10-$15 from the dealer

 

yeah thats i now i remember haha this is the size for sure... basically everything on the car is this size haha

 

Well i just want to get the car together so i ordered it all from the dealer and it will be here Monday. Frickin $71 for the 2 nuts, 2 bolts for the manifold to turbo, 2 nuts and 3 bolts for the outlet to O2 housing and 9 washers. Deff bent over on that one but i'm betting the original ones are pretty rusted in there anyway.

 

damnnnnn you def bent over and took that!!! hahaha but yeah they rust easy so prob better you just got them
