This Aggressor HX35 is a modified HX35 that has a Billet 60mm HE351 compressor wheel VS the 56MM stock hx35 wheel. The turbine wheel on this turbo is a 76X64 10 blade turbine wheel. This combination will give excellent EGT control with a nice bump in power. Spool-up is still great and towing manners are awesome. When compared to stock we have seen over 150 degrees cooler EGT under towing conditions.
