G45 77 89 1.01 T/1.15 T4 (S400 T4 Replacement/Fitment )

for second-gen manifold T4 swapped trucks or any T4 pedestal. Designed to excel with 80%-250% injectors and dual pumps or 10mm or bigger CP3 pumps.  this turbocharger is your go to choice for achieving impressive horsepower without compromising reliability and drivability. We designed these for guys that are mild to wild fueling that wanted a better option then a box s400 with better reliability and no oil seal leaks!!!

The G series lineup has been our go to lineup that we have been pushing a lot harder to our customers then your standard s472/s476/s480 chargers. We are finding these chargers to spool faster, make better power and be more reliable with less oil leaks since they are restricted on how much oil they require to run. Compared to a s400 journal bearing charger they require 60% less and are restricted than typical s400 journal bearing.

These Turbochargers feature

Our custom 77mm 7 blade compressor wheel. (great response and awesome low to mid-range power compared to a 6 or 5 blade compressor wheel with awesome top end )

89×82 9blade turbine wheel. (faster spool, better flow then 87×82 10blade s400 turbine)

Ceramic Dual ball bearing carrier.  (faster spool up and not as prone to overspeed failure as easy)

5″ air inlet and boost outlet compressor cover that is sized and fits just as any standard s400 compressor cover.

1.01ar T4 Divided exhaust housing. (best for trucks that plan to be 850 to 950hp range)

1.15ar T4 Open exhaust housing. (best for trucks that plan to be 1000-1100hp range)

4.62″ exhaust flange. which is identical as standard s400 T4 exhaust housing.

This turbo is a direct swap/replacement for any s400 that is T4 and a 5″ air inlet compressor cover and boost outlet.

Installation is made easy with included install gaskets, and -4an 2 bolt feed fitting. ensuring a seamless install setup process. if you need a cummins -4an feed line we have them instock and can ship with it as well. These do require and will come with a restricted -4an feed fitting that MUST be used with this turbo.
