Looks very nice for a home build. Nice fab work!

Performace? Should make around 700 whp around 15psi (all numbers realtive, as always!) But it should go 9's without too much toruble.

Any chance you could post more pictures of how the turbo kit is run/setup?

Currently building a 4.8 swapped 03 myself. Not turbo this year but I've got a healthy motor, LS9 cam and 317s on it when the time comes

Did you have to cut the floor for the 4L80E to fit-I cant remember how much raised tunnel they have

No it's tight but it went in there. I did have to make my own crossmember.

Yeah I sure wish I could see your manifolds you built! Love your truck, that what mine is supposed to be.

im in the process of building my turbo hot side. I see you have the downpipe going down under the frame. any interference with the front tire?

With a full size front tire it be a problem! Since im running a 4" wide front rim and a 1 1/2 spacer it has room for turning. If I had it to do again id cut the pass side lower firewall back and fab up a new panel allowing for both the crossover and downpipe to fit. It would take away some foot room on the passenger side but I think it be worth it less bends in the down pipe !!
