GtI IHI turbo onto Polo Gti 1.8T

[LZY13B]

Hey mate yeah sold the rx7 and polo and picked up a clean low km mk6

I tested some 3rd and 4th gear pulls and my stage 1 tune peak boost is around 23-24psi around 2700rpm and dropped to around 16psi just over 6k but it’s still enough boost to make it move. But with the mk6 the turbo is mounted straight into the manifold so unlikely it will spool up as quick on polo but would still make a nice upgrade and would bold boost higher compared to the stock ko3s

Just wondering if the GTi guys might be able to give me a hand with something. So I'm still gathering bits for my fitment of a Golf 6 Gti IHI turbo onto a 1.8T 20V. My adapter plate is nearly ready so I'm starting to think about the intake side of things. Can any of you guys tell me what the I.Dmm is of the turbo intake piping at the MAF sensor? I ask because I have a 2.75in and a 3in I.D MAF housing on hand and am not sure which to go with. I'm worried the 3in will be a bit too big for this turbo in a 1781cc application so might go for the 2.75in if yours turns out to be <3in.
thanks
