Speed Engineering turbo systems: Our goal with these kits was to make the most complete, best fitting, most versatile turbo system on the market at an affordable price. Most turbo kits on the market today are either extremely expensive, or really cheap essentially getting what you pay for. Our turbo systems focus on just that a quality well-built kit, without the price tag of a one off turbo system. Our systems utilize Precision 62mm turbos, Air-To-Air intercooler, and your choice of an exhaust connection type.

Our kit has been tested on several 5.3L and 6.2L applications. Horsepower ranges start around 500rwhp, and have seen over 800rwhp with just the change of a spring, or boost controller.

One of the nice features with the sizing of our kit is the ability to run a stock displacement engine with quick spool time. At the same time have a ton of potential to crank the kit up if desired. If you choose to purchase one of our kits we can promise you will not find a better fitting, quality built, budget turbo system for your vehicle.

Features include:

  • 62mm Precision Turbochargers with 62mm Turbines T3 Flange .85A/R
  • Full 3" Exhaust Tubing
  • 1 3/4" Forward Facing Turbo Headers
  • Twin 2.5" Cold Side Piping into Single 3" Engine Inlet

  • Optional Y-Pipe to Factory Exhaust or True Dual X-Pipe Kit
  • 1 Year Manufacturing Warranty

Note: AWD & 4x4 applications will need to delete oil cooler or tap into factory oil cooler unit for installation.

Note: Our kit does not include a fuel system or tuning.

Lots of power for little money

First to install on a SUV. I spent a bit extra and purchased better hoses and fittings for the oil drain lines as mine were leaking quite profusely. Installing the oil fittings in the oil pan was by far the most difficult thing as I did it while on the engine. Take extreme care to get all the debris out of the engine. I had a borescope handy so I could thoroughly inspect it. Recommend removing the oil pan and have the bungs welded in place. Also had to modify the charge pipes to work. Some modification to the intercooler mounting bar as there are differences between the trucks and SUV's.

Forged LME 5.3 block with GPI custom cam, ported heads and a ported L86 intake manifold/throttle body. Snow performance Meth injection, LT4 HPFP, LT4 +30% injectors and hi flow tank pump. Electronic boost controller and 14 psi springs. 22psi on 93 octane but was limiting to 20psi due to APR head bolts. Never got a chance to dyno prior to my stage 4 Circle D transmission rebuild failing but was only getting 12psi due to the injector spike. Hoping to get 16-18psi with the new injectors with full E85. Targeting 1,000+ WHP!
