Adding Twin Turbos to Your Small Block Chevy Made Easier with Our Hot Side Kit
You may think that the LS engine gets all the love when it comes to building a turbocharged ride, but the small block Chevy has seen more than its fair share of turbo setups for both street and track use. From the earliest days of drag racing to the Pro Touring and Restomod movements on the street, turbocharging a small block Chevy has been a popular, if not often complicated, route to making horsepower. It was not uncommon to have to use turbos from truck or marine applications and fitted with specially calibrated blow through carburetor setups making installation and tuning frustrating for all but the most hardcore turbo enthusiasts.
Today, things have changed, making adding a turbo (or two!) to your small block Chevy much easier and with less frustration thanks to Chevy twin turbo kits such as the one we’ve created. High quality brand new turbochargers designed for great power potential (and not designed for a diesel truck) are just one of the many key ingredients that makes turbocharging a small block Chevy so much easier these days. Add in modern aftermarket EFI and the ability to custom tune fuel, timing, and more via boost and you could make a high horsepower SBC turbo built with amazing street manners that can be driven every day if you wanted to. Just remember, any speeding tickets are your responsibility, not ours!
Configured For Two T4 Style Turbos and Ready to Bolt onto Your Small Block Chevy
Our SBC twin turbo hot side kit is based around the use of two T4 turbine inlet style turbochargers. Our kit allows the end user to choose the specific turbos for their small block Chevy build power needs, providing the appropriate boost levels, and mounting for the available space being used as well. A 3-inch V-band clamp turbine outlet will be required when choosing your turbos to aid in the hot side build out using the included 3-inch piping and V-band clamps used in this kit. Configuring your small block Chevy turbo kit to use two turbos means you can create a boosted SBC capable of some major horsepower at lower and safer boost levels thanks to the boost coming from two turbos versus a single unit. Our kit is universal in design to allow remote installation of your turbos under the hood of any SBC powered vehicle. You will need to provide the appropriate oil feed and drain lines for the turbos you choose for your SBC turbo build as well.
Hot Side Exhaust Components to Build the Perfect Twin Turbo SBC Setup
Adding twin turbos to your small block Chevy starts with the build up of your hot side components and our kit provides most of everything you need to accomplish this task. Starting with a set of 1-3/4-inch primary tube turbo headers that can be mounted in a forward and down or forward and up configuration for your build. A pair of concentric adapters are provided to convert the header collectors into a 3-inch diameter outlet, allowing you to build your hot side plumbing via the included pair of 180-degree and 45-degree 3-inch stainless exhaust bends. We also provide a pair of 3-inch V-band to T3/T4 elbows for remote mounting of your turbos vs direct mount on the end of the headers. Using these elbows along with the 3-inch stainless bends and V-band clamps allows multiple mounting options and the ability to clock the elbows for the perfect Chevy 350 turbo kit placement. Finally, a pair of 44mm wastegates are provided in our hot side components to control boost pressures with pre-installed 8lb and 5lb springs for a total of 13 psi of boost control right out of the gate. These wastegates can be controlled via boost pressure/springs or electronically with aftermarket boost controllers.
Add Turbos, Cold Side Plumbing, And More to Build Your SBC Twin Turbo Setup
Our hot side kit provides the perfect starting point for a powerful small block Chevy twin turbo build. Besides the turbos you’ll also need matching induction tubing (based on your compressor housing inlet size) and air filters, and something like our cold side plumbing kit, available in 2.5-inch and 3.0-inch diameters and either polished or black finish, to route the turbo’s air charge through an intercooler to your small block Chevy. Don’t forget to add a blow-off valve to your cold side shopping list to vent boost pressure, preventing compressor surge damage.
While we’ve put together an incredibly comprehensive SBC turbo kit hot side system here for twin turbos, obviously there are too many variables as to just what the customer is building and additional components, including the turbos, turbo oil feed and drain fittings, engine oil return adapters, intercoolers, fabrication of mounting brackets, and more will be required. This hot side system will require welding and fabrication skills and an understanding of twin turbo SBC system design, wastegate and blow-off valve placement and tuning will be necessary as well. Our small block Chevy turbo kit hot side system provides an outstanding starting point for your twin turbo SBC dream build to come to fruition, taking much of the guesswork out of building a Chevy small block twin turbo kit from scratch.
