UPP 05-06 GTO Twin Turbo Kit

When it comes to adding power for your GTO, UPP has got you covered with our new line of complete, bolt on, Twin Turbo Systems.

This system features full T304 SS up-pipes that mate to our cast manifolds, locating the turbos just behind the head lights. On a bone stock LS1 (with exhaust) this system boasts 550whp @8psi. On a LS2 we're seeing 600+whp @8psi, and full boost is achieved by 3000 RPM's. No waiting till red-line for full boost to be achieved as with centrifugal superchargers kits. And no parasitic loss which allows all the added power to go straight to the wheels, not be eaten up by the pulleys!

System includes:

* 2x 5871R Turbos (capable of 1100hp)
* 2x UP-Pipes
* 2x Down-Pipes
* Intercooler Plumbing
* Front-mount Intercooler
* 3-Ply Silicone Couplers
* T-Bolt Clamps
* Stainless Steel Oil Feed Lines
* Stainless Steel Oil Return Lines
* All Necessary Hardware and Fittings
* Turbo Werx Oil Return Pump

This systems is fully customizable and tunable to whatever your application needs are. As with most our systems we don't include a base "cookie cutter" tune with this system. We believe each and every system should be individually tuned based off what your needs are. You have the ability to make the system as mild/wild as you desire!

More Power?

Don't worry, we've got you covered there too! With the base 58mm turbos (5871) the system will support up to 1100hp! If that's still not enough, you can jump right into our Stg 2 62mm Ball Bearing turbos (6182R) which will flow up to 1400hp! Now of course supporting mods are required for higher hp applications, but the system has been designed to grow with you as your needs change.


Not only do we provide the utmost performance with our turbo systems, but we stand behind them. All of our turbos come with an industry first 2 yr warranty, and all of our manifolds/piping comes with a Lifetime Warranty. Top this off with a customer service support that's second to none! It's no wonder so many people choose UPP for their forced induction needs!


We realize that everyone and every system is unique. Because of this we have a series of options available to help better suit your needs.
* Injectors- 60lb/hr standard, 80lb/hr (+$100), 96lb/hr (+$200)
* Turbos- 5871 standard (58mm, journal bearing), 6182R (62mm, Ball Bearing) (+$899)
