    stage two turba!

    Posted by jim D. on Jan 10th 2026

    This is a great buy! Got mine on sale with a discount. Truly a bolt on OEM stage two turbo! No modification needed. Arrived fast and shipping was free! Thats a huge deal! Consider that they for free shipped this all the way to alaska at 50lbs for free.... simply amazing value! Works out of the box and packaging was great! They did custom foam bricks and include oriface seals on all the holes that you dont want foreign objects in. I wish theyd let me upload photos to show off their packaging job so that other folks know what to expect. I also ordered their gasket set with this turbo which was included in the same box as the turbo. The recomended gasket set actually provided all the gaskets from like 2001 all the way to 2010 if im not mistaken. They included a syringe for preoiling the turbo. They literally thought of everything in that gasket kit. I would not hesitate to buy from cardinal again especially for turbos! Hope this review helps!
