What do you need to make 600HP in your LBZ?

600 RWHP (Rear Wheel Horsepower) with your LBZ makes one of the most fun trucks to drive!  They sound great, look amazing and feel like a rocket ship if you do it right.  

(Chuck Dilley's LBZ  was actually a lot more than 600HP when this picture was taken, but it's a great picture)

There are many recipes out there to make this power.  Each with it's own advantages and shortcomings.  Below you will find our recommendation assuming you meet this criteria:

- Drive-ability is crucial! It's not just about a number on the dyno, you want to be able to daily drive this build when you are done.

- You are NOT trying to sled pull in a 2.6 or larger class.  

- The truck must maintain its reliability.  You don't want to constantly worry about blowing a motor. Or maybe you tow with it and want to (or have to) still let the wife drive it once and a while. 

Stage 1 (~430RWHP)- (~430RWHP)- This set of modifications maximizes the value and reliability per dollar on a truck with a stock transmission.  Reliable power levels up to 430rwhp can be achieved with this set of parts.  The  factory transmission parts are the limiting factor.

 Includes:

• Fuel system (suggested) - FASS 150
• Tuning: Stock trans EFILive Tuning / SPADE Jack

Stage 2 (~530RWHP) (~530RWHP) -This set of modifications maximizes the value and reliability per dollar on a truck with a built transmission.  Reliable power levels up to 530rwhp can be achieved with this set of parts.  The  factory turbocharger is the limiting factor. We highly recommend gauges with this setup, as it’s limited turbocharger capacity means it has the potential to run high EGT’s which (left unchecked) can cause engine damage.
