The KC Turbos 300594 DIY Drop-In Balanced Assembly Turbo Kit With Extended Tips is a perfect upgrade for someone who is looking for a little quicker spool and a little more airflow. KC Turbos Testing has shown that the 11-blade single-plane wheels perform much better than the stock dual-plane design.
The KC Turbos 11-Blade Turbine has been designed to flow much more efficiently while reducing EGTs. In turn, this will give you a lot more on-the-top-end performance. Another perk to the 10-blade design is that it will give you a very loud whistle sound, Some even say it sounds like a jet engine!
