I will be getting my gt28rsr next week and i have sorted out my exhuast, but i don't know what bolts to use to bolt the 5 stud exhuast fange to the turbo. Can i use normal short 13mm bolts or do need special allen key bolts (what thread pitch and length do i need)

Thanks Ash

I think the thing to be aware of is that it's easy to have a situation where the bolts get loose and eventually fall out.

I think the best option is to use studs and then those locking type nuts that you get like are used on the manifold/turbo join.

Yup as B says they do seem to have a habit of working loose, but I've used some spring washers to stop this.

So you can use normal studs that you use on the head for the exhaust manifold. I have 4 spare i am sure i can find a spare from work.

Thanks for the replys.

Yeah that would work.
