VQ37VHR Air to Air Supercharger Kit
In part 1 of our G37 Supercharger for the VQ37VHR article we covered the Vortech V3 SI supercharger. In part 2 we covered the fueling components we used with our CJ Motorsports S1.SE fueling system. In this article we’ll be covering our VQ37VHR Air to Air Supercharger Kit supplied by Soho Motorsports.
Back in part1 we discussed two options when supercharging your G37 or 370z. Option 1 is the CARB legal kit made by Stillen which utilizes the smaller V3 Sci compressor from Vortech and among other things an air to water intercooler. This is a great option for those that want to literally boost their car to the GT performance machine we all wish Nissan would have made available from the factory. Option 2 is what we went with which is an ‘Air to Air kit’ supplied by Soho motorsports.
Soho incorporates the following Stillen components in their kit
- The Stillen intake manifold (which relocates both intakes to the passenger side)
- The Supercharger mounting bracketry and pulleys for both the blower assembly and the revised accessory belt routing
- Maf extensions
- Wrench for installing the intake manifold and bolts for mounting all of the above
The Stillen intake manifold will be a showstopper at the local car meets. Both throttle bodies are relocated to the passenger side of the engine compartment which provides routing for the intake charge pipes in both kits. It’s finished off in a nice black wrinkle coat paint along with the Stillen logo milled into the aluminum. Our intake manifold has had the air to water heat exchanger removed and instead it will be sealed off with a block off plate. A new factory gasket for the manifold is supplied along with new mounting bolts.
The pulleys and accessories
Unfortunately, most of Stillen’s billet bracketry will be covered up in the already crowded engine bay. Extensions for the relocated mass air flow sensors and a longer belt for the current drive accessories is also included. There’s an additional belt to power the pulley for the jackshaft. Finally there’s new high grade bolts to mount these accessories and bring life to our supercharger.
