TiAL® GT30 V-band Turbo Housings are manufactured from stainless steel to ensure long lasting performance. These compressor housings are physically smaller than traditional cast turbo housings and offer nearly a 33% weight reduction. TiAL® Turbine Housings are designed to mate with Garrett® GT Series Turbocharger’s and are offered in a variety of A/R sizes. Typically a smaller A/R will offer quicker spooling for better response at lower RPM’s. The downside to choosing a lower A/R is that you sacrifice peak power at high RPM’s due to the higher exhaust back pressure. Therefore, if your goal is to reach peak horsepower and aren’t worried about response times, then a higher A/R would be better suited for you needs. Typically higher A/R compressor housings are chosen for racing applications and lower A/R’s are chosen for street applications.
Note: These housings will not work with the 700177-23 GT3071R CHRA, the heat shield is different, you must use the 700177-22 CHRA
