I Am Curently Pieceing A Front Mount Turbo System Together On My 05 Serria Denali 6.0l Awd. I Found A Innovative 67mm With .70a/r Housings On Both The Exhaust And The Compressor Housings. What Would Your Recommendations Be??

Just Looking For A Fun Truck To Be Completly Streetable With It Coming Into Boost Only When I Need So A Bit Of Lag Is Not A Bad Thing. What Do You Guys Think??

My Thaughts Were A 67mm Or A 76mm But Wanted To Find Out More Details Of What Would Be Better. Im Also Not Looking To Make Extreme Numbers, Maybe 400 - 500 Hp Or So.

 

I would run a .81AR on the exhaughst. I ran a T66/.81AR for awhile on my 6.0l, and it ran well. It just ran out of breath when I brought it up hear to high altitude. At sealevel it made 12PSI no problem. The 67 should be a tad better.
