Center Housing


G-Series turbochargers feature a V-Band CHRA connection for enhanced ease in installation and adjustment. Each model includes a -4AN fitted oil restrictor with a 1MM orifice to maintain a 40PSI oil pressure. 4 large water jacket ports provide increased cooling capability, and facilitate custom water line placements, streamlining installation. The turbo has two -6AN connections and two plugs, and is recommended for water lines to be installed on opposite sides of the housing.



Turbine Wheel

Featuring the latest advanced ultra high flow aerodynamic designs with the Garrett G Series Turbine Wheel, the G Series models offer previously unobtainable improvements in spool and power levels by frame size. The G-Series Turbine wheel is constructed of Mar-M super alloy material. This material is designed to withstand up to 1050° C - that’s 200 degrees more than inconel turbine wheels! The newly engineered turbine wheel with optimized G Series aerodynamics increases flow up to 15% (Compared to GTX Gen II) more than the GTX and has a peak efficency of 74%.


This guys are hands down the best turbo specialist in South Florida. Well worth the 2 hours drive. Got my Perkins Marine turbo Remanufactured and all I can say is wow. From a rust bucket to a brand new looking turbo in 3 days exactly. Just as promised, and the best part is I saved over $1k compared to the cheapest price I could find. They just got a life long customer.
If you are looking for a true turbo specialist, give these guys a call. Highly recommend them!
