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 intercoolersblow off valveswastegates, 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 a 2.5-inch V-band inlet flange and 3-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 2.5-inch outlet.

The 2.5-inch V-band exhaust inlet flange means the turbo will easily mount with a standard 2.5-inch V-band clamp, while the 3-inch turbine outlet is easily plumbed with your choice of 3-inch tubing secured by a 3-inch V-band clamp. The compressor inlet and outlet are slip-on connections that are easily retained using hose couplers and T-bolt style clamps. The compressor side of the turbo uses 2.5-inch tubing to plumb the outlet to your engine.

The 6762 turbo size makes great power on most smaller displacement engines, such as inline fours, and inline or V6 engines. The 6762 can also be used quite well in a twin turbo setup on V8 engines of 300 cubic inches or larger and is the perfect start for the popular 5.3 LS turbo kit swap. We offer a standard rotation version of this turbo for mirror image twin turbo builds. Spool up is quick with the .83 A/R turbine housing and cast compressor wheel, netting an average of 1,000 wheel horsepower on a typical small block twin turbo setup with supporting components for airflow.

We Have Everything Your Custom Turbo Build Needs

Those bargain online 67mm turbo deals may save a quick buck, but then leave you on your own to source everything else to make your boosted dreams reality with statements like “no instructions, professional installation recommended” and so on. We love boost just as much as the next person and we have the parts on the shelf to ensure your turbo build happens without delays.

Take our T4 oil feed and drain kit, which has everything you need to plumb your engine’s pressurized oil to the turbo’s center housing assembly. To get your turbo’s hot oil back to the pan for cooling you’ll need our T3 oil drain adapter along with the AN -10 fitting of your choice. At the oil pan you’ll need to add an AN -10 weld on bung fitting or you can bolt on our LS swap oil pan with built in turbo oil drain fitting if you need a swap pan anyway.

For those you considering building a turbo LS combo with twin turbos (one is good, two is great right?) then you might want to use our LS twin turbo oil drain timing covers. We offer these custom oil drain timing covers in both a Gen 3 and Gen 4 version for your LS twin turbo build.

Lastly, we have everything you need to build out your hot side and cold side systems, including turbo headers for numerous applications, and LS turbo manifolds like our LS cast iron turbo manifolds and LT cast iron turbo manifolds for your hot side. While air intake tubingair filters, and intercooler piping are available to finish your cold side build. Not to mention many accessories, from boost and air/fuel ratio  gauges, to AN fittings, plumbing, and more can all be found via our category search or just drop what you’re looking for in our search box!

Build the 67mm turbo combo of your dreams with our VS Racing 6762 turbo as the heart of your twin turbo project build and be ready for the crowds when you open the hood at your next event!
