Quadstar Tuning LLC

  • $349.99
  • Save $25

Complete install kits for customers who wish to acquire their own turbocharger for a "Do it Yourself" DIY install. 

There are 2 styles available due to different backing plate designs on the turbos:

  • Wastegated HX35, HX40WII, WH1C
  • Wastegated HX40W


  • Flexible hydraulic style oil drain line with fittings
  • TIG Welded Exhaust adapter with bolts and new clamp
    • Featuring CNC sealing ring for downpipe connection
  • Intake coupling and clamps for attaching to factory plenum. Trimming required
    • We can also retain the v-band connection on the turbo (at additional cost) by including an adapter for a stock 2.5" plenum or our high flow 3" plenum. These can be added to any existing order by request.
  • 4x turbocharger mounting bolts and nuts
  • Oil supply adapter fitting that re-uses the fitting and supply line from the stock turbo

Also, check out our high flow plenum upgrade to make your swap a complete bolt-on operation where you can add a v-band adapter as an alternative to cutting the compressor housing flange off.
