Does anybody know the internal diameter samco pipe i will need to connect my vf34 turbo to the intercooler (elbow pipe), i have found the pipe im after on roger clark motor sport though there is a choice of four 60mm, 63mm, 70mm, or 76mm?

Thanks

 

A far as I know, the size is 51mm inside diameter. Thats what was needed for my VF29 and STI8 IC.

 

Yes it's 2" OD AFAIK. That's on my VF35, both to normal TMIC pipework and to my old Samco set up as well.

 

Is it 2" OD or ID? I can't honestly remember, its been ages since I did mine thats all.

 

51mm ID

 

Best to measure both the turbo and intercooler, because you might need a reducer elbow.
