Here is are Upgrade Great Options for Garrett GT3071R Turbine Housings. 

First Measure Your turbine Shaft. These Housings are for the 55mm x 60mm GT3071R Turbine Shaft. This is the .82 a/r Turbine Housing.

 

 

 

The GT3071R Turbine Housing Options Are Available in:

  • .63 a/r
  • .82 a/r
  • 1.06 a/r

I Highly Recommend the .82 a/r Turbine Housing for the GT3071R Turbo, If you have a GT3076R  .82 a/r and the 1.06 a/r turbine Housing are Great Candidates. 

Choose Your Turbine Housing Based on Your Engine Size, Turbo Size, and Amount of Power You are Trying to Achieve.  

  • Smaller Turbine Housing = Faster Spool = Limited Peak Higher RPM HP
  • Larger Turbine Housing = Little Laggier depending on the Engine Size = Increase Peak Power at Higher RPM
  • NOTE: If you Chose a Turbine Housing Too Small for an Engine, Then the Engine Can Start to Outflow What the Turbo can Flow with the Size Turbine Housing You are Using At Higher RPM. This Causes the Power Level of the Engine to Feel Like It Cannot Pull Harder at Higher RPM (6500 RPM) and it Becomes Harder for the Turbo To Hold Higher Boost Levels at Higher RPM, Because The Amount of Air Cannot Disposed of Passed the Turbine in a Specific Time Frame (lb/min).

 

Here are my Recommendations:

  • 4 Cyl 1.6 liter > fast spool >Engine Rev Limit approx 7500 rpm>.63 a/r> 425 HP limit
  • 4 Cyl 1.6 liter > Little Laggier >High RPM >.82 a/r >500 HP limit (Highly Recommended)
  • 4 Cyl 2.0 liter > fast spool >High RPM >.82 a/r >500 HP limit (Highly Recommended)
  • 4 Cyl 2.0 liter > Little Laggier >High RPM >Run GT3076R>1.06 a/r >550 HP limit (Highly Recommended)
  • Larger that 4 cylinder 2.0> Go with 1.06 a/r > Consider going with a GT35R if you going for 600 HP
