I need to make up a custom down pipe for this turbo on my 4x4rs2000 project

am told its a t34 hybrid but need to i.d. the 3 bolt outlet bit so I can locate/source a flange for it to make a custom down pipe - CR Turbos who refurbed it said its from one of the cosworths but didnt give me any more info than that

the bolt centres are 95mm



also would be good to know where to get a flange/downpip to modify please

all help much appreciated
