Default Sierra turbo build up.

I was not sure on where to put this but thought this was the best place for it. I've been buying parts for my truck here and there for over a year and I finnaly have most of the stuff to really get going. The truck is a 2001 gmc sierra. Plans are to redo the complete suspension, get the truck to weigh around 3300lbs, drop in the 408 and s480. The truck is going to be bagged and bodydropped. It will also have brackets for coil overs out back for track duty. So far heres a list of what I have.

408 built by Erick and the guys at HKE
4l80e That needs to be built
S480 Turbo
Ford 9"
Synapse wastegate/blow off vavle
1/2 header flanges
1.75" SS header tubing
2.5" SS tubing for hot side
4" SS tubing for cold side
4" SS tubing for DP
15x14 Weld pro stars with 33x10.5 mt
walbro 255 dual intake pumps, fuel rails etc..

So Far I've started working on the frame. I'm going to build a 4 link out back, replace all the bulky crossmember with 1.50 tubing, build new tranny crossmember, build tubular k member up front and tubular a arms. Heres some pics. This is my first turbo build so any suggestions are really appreciated. I'm sure I'll have a ton of questions later.

You can upgrade that S480 to an 88mm turbo by a simple cover from Forced industions for more power!
Awesome build, keep up posted!

I'd like a little more info on this. The s480 I bought has a race cover. Is this the same cover your talking about?? I'll have some new pics up late tomorrow. I'm going to back half the frame and hopefully have the front end done.
