1,050 HP, 6.0L Single-Turbo LS - Complete
Type: Engine Packages
Vendor: Borowski Race Engines
Description:
This is a lot of power for the money!
We kept costs down using seasoned GM block and heads that we have redone from top to bottom on our CNC machines. Extraordinary performance at a great price is delivered by our integrating outstanding parts with our precision machining, assembly and dyno tuning.
The crank we use is a stock-stroke, forged Callies Compstar with 8 counterweights. The additional counterweights increase overall stiffness by about 25% and reduce harmonics so that the crank does not want to flex as much. Bottom line is that the engine lives longer because crank bending and twisting under heavy load is minimized. The forged rods are Callies Compstar Extremes. These are topped with Diamond R series dish pistons.
The top-end features seasoned GM LS3 heads that we port our 5-axis CNC. We also machine the combustion chamber to optimize for boost. The valve job and bowl blending is done on our Newen CNC. The heads are assembled with our custom hardware and COMP BSR shaft rockers for maximum valve train stability. A custom COMP hydraulic roller cam brings performance and durability without the maintenance hassle of frequent valve lash adjustment with a mechical cam.
We can build this engine with a range of intake manifolds. The default choice is a Holley Lo-Ram. This intake, along with its sister the Hi-Ram (shown below), allows use of a liquid-to-air intercooler between the base and lid. We like this system because it is compact and very effective at cooling the intake air. The effectiveness can be further enhanced with an optional FI Interchiller which uses the AC compressor to refrigerate the intercooler system. A completely different alternative is to run E-85 exclusively and eliminate the intercooler system entirely thanks to ethanol's evaporative cooling. Regardless of how you do it, holding the intake air temps down is critical. Water-methanol injection is a great supplemental means of keeping IATs down.

That brings us to the patented, top-shelf, Bulleye 76mm NLX turbo with its all-ball-bearing design which speeds up spooling. Since no center nut is required, the NLX has a three dimensional compressor wheel with greatly increased vane area allowing it to capture more air. The NLX also has an adjustable MAP grove for easy turbo tuning. Check out the video we shot at Bullseye to get more info on these amazing turbos.
The exhaust headers you'll need depend on the installation parameters. On our dyno, we use either Stainless Works or our BRE customized Hooker wrap-around turbo headers. We can supply either type header set along with the Turbo-Smart hardware or you can source your own.
A Holley Terminator X engine management system runs the whole show with flawless precision. Your engine will be delivered to you with the tune from your dyno session already installed. The optional Terminator X-Max will aslo act as a tran controller. Either can be paired with an optional Holley Digital Dash to solve all your instrument issues.
Want to customize the look or performance of your engine? No problem. A range of serpentine systems are available and there are lots of personalizing touches we can add.

THIS ENGINE IS NOT POLLUTION CONTROLLED AND MAY NOT BE LEGAL FOR ON-ROAD USE IN YOUR VEHICLE.
NOTE:
1. The distance from crank centerline to the top of the Holly Hi-Ram manifold is approximately 22.5 inches without the intercooler and 26.5 inches with the optional 417 Motorsports intercooler such as we used for dyno testing. In either case, this will require a cowled hood on most vehicles.
