FAQs - Turbo Kits Explained. What is a Turbo Kit by Grant Smith

“Turbo Kit”… When you think of that package, what comes to mind? Sure, you’re likely thinking of a Turbocharger first, and maybe a blow off valve second- everyone wants a BOV, but when you consider the amount of time involved in configuring the whole bolt on package, the volume of hours is staggering! Pre-Production R&D is critical to building a quality, efficient kit and crew at TurboKits.com knows this! It isn’t out of the ordinary for them to spend a year in testing, tuning, tweaking, and improving a turbo system before releasing it to market. Ensuring the turbo is the correct size, the wastegate regulates boost properly, and the blow off valve sings that perfect tune, is part of the process. Although converting a naturally aspirated vehicle to forced induction may seem simple with a kit from TurboKits.com, it IS that way because the package is application specific. Your intercooler piping will be mandrel bent to fit your specific vehicle, the turbo exhaust manifold is designed for bolt on fitment, and the intercooler will tuck perfectly behind your stock bumper cover. Vehicle specific oil feed and drain lines necessary for turbo lubrication are included as well as the hardware and instructions. Is Technical support important to you?

If your plan is to convert a naturally aspirated vehicle to turbo, most intercooled kits will be set to run around the 8 PSI level. At that pressure, a HP gain of roughly 60-70% over stock can be achieved with proper tuning. And YES, tuning is the key component when adding a turbocharger to your vehicle. In a naturally aspirated form, the ideal stoichiometric mixture for a gasoline engine is roughly 14.7:1 or for every one gram of fuel, 14.7 grams of air is consumed. After a turbo has been installed, the target air to fuel ratio changes to 11.1:1. Fuel is used as an aid to cool the cylinders and reduce the chances of combustion chamber detonation. Take the time to scroll through the complete kits at TurboKits.com, and you’ll likely note an electronic tuning solution is offered. These “controllers”, whether they are a piggy-back style- work in conjunction with the vehicle’s original computer, and OEM vehicle ECU recalibration, or a full stand-alone option, will need to be installed along with the turbo to achieve the desired air/fuel ratio and to control ignition timing.  Timing and fuel delivery control are commonly adjusted based off information gathered by a MAP (Manifold Absolute Pressure) sensor. As the sensor “sees” pressure increasing, or “boost”, the electronic tuning device signals the injectors to flow more fuel and adjust timing based off the amount of pressure gain in the system, thus, maintaining that target 11:1 Air/fuel ratio under boost!


In addition to the electronic tuning device, another critical component of the turbo system is the intercooler. Maintaining a cooler air charge will provide a denser air charge, improving power output along with lowering the likelihood of combustion chamber detonation. The quality intercoolers provided with most of our kits are vehicle specific, so mounting tabs are installed, the proper couplers and clamps are utilized, and the correct inlet and outlet locations are chosen for ease of fitment and pipe routing. Compressing the induction air and the friction caused by the air passing through the charge piping, increases engine intake tempers. Amazingly enough, even on very hot days, a well-designed intercooler system can lower engine intake temp close to ambient air, even under hard boost pulls!

Turbo Manifolds

Once you’ve gotten your vehicle up and running turbo, fair warning, boost is addicting! Your craving for more power may overwhelm you and soon, you’ll be back on the phone with the team at TurboKits.com. More PSI, you say? Adding a boost controller, larger intercooler, bigger fuel system, water methanol injection, and even upgrading engine components to support that higher boost goal will likely be on your shopping list. While most kits come with a high quality journal bearing turbo, upgrading to a billet wheel, ball bearing configuration will ensure you have the latest and greatest in turbo technology!  More power per pound of boost is the goal and the modern aero wheel designs provide faster throttle response and spool time. Internally and externally wastegated turbos are both available with the latest in materials and construction.

Don’t see a kit for your specific vehicle? Our experts can help size the proper turbo, boost control pieces, intercooler, and piping to meet your needs and goals. The extensive number of available turbo options means selecting the proper components can be overwhelming. With over 50 years of combined experience, chances are we’ve successfully configured a build similar to yours. When building a custom turbo package, fabrication or access to a skilled fabricator will be necessary. Without and off the shelf turbo kit option, you’ll need to assemble your own exhaust manifolds, downpipes, and custom install intercooler piping. Although this isn’t an ideal option, you’ll have the confidence knowing you’ve sourced the right components with the help of TurboKits.com.

Full Turbo Wastegate and Turbine Housing

Let’s not forget the factory turbo applications! TurboKits.com offers turbocharger rebuild services, replacement parts and rebuild kits, along with upgrade packages, custom coatings, and porting. Mass produced, OEM vehicle turbocharges have tremendous room for improvement! Our expert team can machine your stock housings to accommodate larger, more efficient wheels, port your housings for improved flow, and balance your assembly for extended life and optimum performance. In most cases, gains in the 80-100+ HP range can be achieved while utilizing your existing components to save you money and maintain that OEM bolt on fitment. Our turbocharger upgrades are the best “bang for the buck” in you quest for added power. Additional supporting modifications and tuning will need to be addressed during the turbo upgrade process.
