This is a great turbo for those looking to push the limits of their truck and get a lot more out of them over stock. This turbo is made for those who are looking for more top end power but still want to have the ability to tow max weight. This turbo will tow max weight as long as you watch your temps and keep your rpms up. This turbo has a very similar whistle to the powermax/2003 turbos. SPECS: 64x88mm single plane billet wheel with extended tips, .72ar race compressor cover, 72.5x66 10 blade turbine wheel, new high flowing billet vanes, and upgraded 360 thrust bearing. 100% drop in (no modifications required).
