hey sk, i was only going of what they said that a rb25 inlet manifold has to be modded to fit that all. and the reason for changing the turbo is to go to a dedicated externial gate turbo.not such to go bigger just better.and as for advan i cant complain they done a great job .and will find out soon about the inlet part as it should be here early next year . my car is no race car just a volvo with more go then standard which is all i was after. and yeh it doesnt make boost till 3 but it ok i dont realy mind it comes on hard when its on .my mates stagea is running a gt35r turbo comes on no different to mine just it has the dedicated externial gate rear housing.
cna you please tell me what diff my 90mm throttle body and inlet will make cheers .and with a tune what it should make .
