Turbo pipework....

[Jono FD3]

Guys, can you help me???

I need to know what size pipe is used for the folowing sections:

1) Exturnal size of the Small bore section of the Y pipe (the bit with the rubber O ring that slides in to the pipe from the second turbo)
2) the size of the pipe that is used for the IC.

I\'m going to be doing the V mount soon & I would like to order the pipework before I start the job as I\'m going full on custom from the turbo to the plenum elbow!!
