I am about to install my turbo kit on my 2000 civic si, and the bolts will not go into the 2 & 3 runner holes on the top of the manifold. I have read in previous post to replace them with studs and nuts. but does anyhow know the pitch thread and size i need to get for my car. I bought the kit used, should i have gotten these? i got everything else.

Car: 2000 civic si
Kit : Greddy Si Kit, 18g

8mm x 1.25

 

Alright i am almost 100% sure it is a 1.25 thread, but 8mm sounds kinda small doesn't it? i was told 14x1.25, and this sounds about right.

8mm is the size ( width) of the bolt...
