Stage 1.5 Package - 380HP | OBS 94-97 7.3

Stage 1.5 Package - 380HP | OBS 94-97 7.3L

Our Recommended Turbos:
#1. Irate Diesel T4 Mount kit with S364.5SX-E - This is our MOST recommended turbo for these injectors. No compromise.. Fastest spooling, most responsive turbo and perfect for these injectors at any altitude. And on OBS trucks this will come with most components needed to add an intercooler so, kill two birds with one stone!

#2. KC Stage 1 (63/68 .84) - This is our preferred drop in turbo, Fast Spool up and will get you the max power from these injectors while still being very responsive for towing and daily driving.

#3. A simple billet wheel in most cases will suffice with these injectors, this will leave some power on the table and not the best EGT Control but will work in a pinch and is mandatory (at a minimum) to keep the turbo from having surging issues on L99-03 trucks.

Will my Stock HPOP Be OK? 

What Transmission Upgrades Will be needed?

If this is a daily driver/tow rig that is not beat on constantly, a healthy stock transmission with a shift kit and torque converter upgrade will generally last very well. 

Auto Trucks - For a VERY good replacement transmission, we recommend this Sam Wyse.
Manual Trucks - If your truck is a manual, our recommended clutch is this South bend.

Will a Fuel System Be Needed?

For max potential, you will likely need an E-Fuel System like this Irate Diesel Fuel System. 
On the stock fuel system, you will likely be limited to around 350hp on a stock fuel system.

What Can This Kit Be Used For?

This package is great for towing any weight and fast spool up, while staying reliable and not needing head studs, valve-springs, and pushrods or an upgraded HPOP.

A stock OBS truck will dyno at around 150HP and 325lb.ft of torque. 
This setup is capable of 380-400HP and 700-750lb.ft of torque.

Paired with 1023 Diesel Tuning this setup is clean, cool and perfect for taking that stock truck to the next level and keep up with the new models rolling off the assembly line.
