there are a few different exhaust sides that will bolt up. Carlos posted some pics of what looks to me like standard flange on a TD04 for a Mitsu 4G engine. For the 300Z kit they came with T25 flanges, and I am sure they have a triangle 3 bolt available too. For the compressor side there is the TD04 series or a few TD05's - 12B and 14B. I have never seen a TD05 16G with the Mitsu T25 exhaust side but I suspect that it will bolt up too.
