P-reg URS6 (4A) AAN Intercooler pipe diameters please

Hi.
Can anyone please tell me, off the top of their edd's, what the pipe diameters are for the following please:

1) From the bottom of the compressor side of the Turbo (under the car and across to the IC) the actual diameter of the turbo outlet, in other words

2) The Intercooler inlet pipe diameter

3) The Intercooler outlet pipe diameter

I am collating bit's and bobs for an FMIC and could do with the sizes so I can get them ordered off of Ebay - It's pittlin it down outside and I ain't got a garage

Thanks
