Information concerning HMMVEE Military Hummers and H1 civilian vehicles.
Peninsular has repowered many civilian H1 from the early H1 non turbo vehicles to the 1999 turbo vehicles.
The non-turbo version requires a body block to raise the body 1.5″ to 2″ for installing the turbo engine. Peninsular has developed a rear turbo 6.5 that will produce up wards of 300 hp for the performance required by some users.
The repower from the early non-turbo vehicle is extensive with a transmission change, drive line change and requires a close study for all the components to insure a well engineered vehicle. The Peninsular rear turbo engine is available with stainless headers, turbo, and stainless exhaust elbow for better heat control and turbocharger spool up. The engine water pump upgrade is the 126/gpm water pump with twin thermostats along with new idlers and pulleys for the serpentine belt drive.
