Turbo Specs:

• OEM turbos for the engine are 44mm turbine and 45mm compressor, these turbos are 54mm turbine and 54mm compressor which is a GTX3071R turbo.
• Billet aluminum compressor wheel for high flow
• They have 7075-T6 high strength aircraft grade billet aluminum CNC machined center sections hard anodized gold saving 2lbs per turbo (4lbs total) and much stronger than the stock castings and ALOT better at heat conduction to keep the turbos cool.
• The bearing housings have a super expanded 5x larger internal water jacket for extreme high performance cooling.
• They have a dual ceramic ball bearing cartridge which provides best possible spool and durability.
• Comes standard with a 2 yr warranty.
