Your Custom Turbo Build Begins Here
Chances are your daily driver has at least one turbo on it, as all the major manufacturers offer small displacement turbocharged engines in cars and light duty trucks to help fuel economy. Or perhaps you have a turbo diesel truck to pull your car trailer. Whether it is that daily driver, the show field, or the race track, turbos are getting a lot of attention these days. It’s not hard to agree that we can all thank the popularity of TV shows like Roadkill and magazines like Hot Rod where junkyard LS swaps are performed, and they strap on a cheap turbo in the name of maximum horsepower for minimum dollar. It makes for great viewing and sells magazines, but in the end they usually fail spectacularly.
We know you work hard for every extra dollar you want to put into your project and that’s why we offer quality parts at competitive prices. If you’re considering building a turbo LS combo, or looking at going to a turbo on any engine for that matter, we offer the VS Racing line of turbochargers that combine quality materials and great power output in a industry standard package that leaves plenty of change in your budget for supplemental parts such as , , , and more for the rest of your turbo build project.
Quality Build Materials for Years of Trouble Free Boost
Not all turbos are built the same. There is a lot of cheap junk out there and those that have bought said junk soon regret it. We all love a deal, but there are certain parts you should spend a little more for peace of mind and a turbocharger is certainly one of them. This is why the VS Racing turbo is built for the long haul with quality journal bearings, high temperature seals, and more.
Starting with a precisely machined cast iron turbine housing that uses the popular T4 mounting flange and 4-inch V-band clamp outlet, VS Racing fits their cast aluminum compressor wheel and oil cooled journal bearing center housing assembly and then finishes the turbo with its cast aluminum compressor housing with 4-inch inlet and 3-inch outlet.
The divided T4 exhaust inlet flange means the turbo will easily mount with any you decide to run, and the 4-inch turbine outlet is easily plumbed with your choice of . The exhaust side uses standard V-band clamps to secure, while the compressor outlet uses slip-on connections that are easily retained using and .
The 7875 turbo size makes great power on most any V8 displacement of 300 cubic inches or larger and is the perfect start for the popular 5.3 LS turbo kit swap. Spool up is respectable with the 1.25 A/R turbine housing and cast compressor wheel, netting an average of 700 wheel horsepower on a typical small block with supporting components for airflow versus its cast turbine wheel version.
