GTP38R Garrett 739619-5004S Ball Bearing Turbo Upgrade


Garrett came out with a high performance drop in ball bearing GTP38R turbocharger upgrade that changed the 7.3 Powerstroke performance industry. This turbo can supply over 500 hp of air and the specs prove it has the flow to make it a true performance or towing turbo. The 38R turbo for the 7.3 Powerstroke is a direct fit drop in turbo with lightning fast spool up and a larger more efficient 66mm compressor wheel. With this turbo kit, you will experience Garrett GT dual ball bearing technology working to give you unbelievable power pushing you back in the seat every time you push the throttle. The 38R has stood the test of time. It's the premier drop in ball bearing turbo for the 1999.5-2003 Powerstroke. It has an amazing sound and great performance with enough flow to support 238cc hybrid injectors. 

The GTP38R Turbo has the Garrett exclusive ball bearing cartridge for unbeatable response, efficiency, and durability for your 7.3 Powrestroke. Elimination of the thrust bearing of a stock turbo eliminates failures at elevated boost levels with this design. Stock turbos are limited by 32-34psi while the Powermax can sustain a monstrous 40psi. The 88mm GT compressor wheel provides 33% more flow than the stock 80mm wheel. The ported shroud housing improves the compressor flow range for superior surge control. The 1.00 A/R turbine housing gives a reduction in back pressure and as much as 200 degree drop in EGT's. Maximum recommended boost level is 40psi on the Powermax.
