Hahah I need to update that thread, I randomly saw this thread started and had to reset my password to log back into this group, it's been many years.
My truck has been ls swapped for probably 6 or 7 years, it was a stock 5.3 with 4l60e, started to get bored with it so I pulled the heads and installed a cam and port and polished the heads. I used the hooker manifold that holleys sells for the passenger side, used a stock driver manifold on the driver side, made my own crossover. I wanted to keep AC so I had to place thr turbo in a different place then I've seen many others do. I ran a 3" intercooler behind the grill. The downpipe is 3" until it's under the cab and it goes to 4" out the back of the truck behind the rear tire. I'll work on updating my thread and with more pictures and videos
