As some of you may know, I sold my last project back in August. Then bought this new one shortly after. I love the car and setup, I just needed to change some things up on it I really didn't like.
Setup as it came with the car;
• Forged 347
• Ported and polished 5.3 heads
• ARP head studs
• GM MLS head gaskets
• Comp Cams 220/224 .564/.568 115 lsa, custom turbo grind cam
• LS6 intake manifold
• Full A/C, heater, etc.
• 12 bolt
• 58mm Precision turbos (2) – T4
• Custom built, thick walled stainless steel headers
• 3” Stainless steel downpipes, connecting into 4” stainless exhaust, then dumped before the axel
• Stainless steel charge piping
• 2in – 1out air-to-air intercooler (polished)
• 38mm Tial wastegates (2)
• 50mm Tial Blow-off valve
• eboost2 Electronic boost controller
• Twin 255lb Walbro fuel pumps (2)
• Custom pressed steel-braided fuel lines
• Aeromotive fuel pressure regulator
• Aeromotive fuel rails
• 83# high-impedance fuel injectors
• Mallory fuel gauge isolator
• Snow Performance Boost Cooler methanol injection kit
Here's how the car came when I bought it;

Car had completely stock suspension down to the torque arm (other than a bmr k-member), so as soon as I got it, that was my first priority.
Installed;
BMR torque arm
BMR torque arm relocation
BMR panhard bar
BMR front upper and lower A-arms
BMR rear lower control arms
BMR rear lowering springs (with hose mod)
Strange single adjustable shocks (front and rear)

Car came with a custom kit with log manifolds that keeps all accessories in the factory location which I really liked. Cold side was in stainless so I wanted to redo it in aluminum to try and keep IATs down a bit. Couplers kept popping off the old system so I re-made the coldside to only have 4 couplers instead of the 10 it had before lol.
Switched to an Edelbrock Pro flo intake. And I'm using the old fuel system I had on my last car, along with a few other things.... here's some pics. I'll keep updating when I'm done which shouldn't be too long.
battery relocated to the back;

Thanks guys!
Yeah it's the same car the kit was built for. Thanks man!
Yep, still a T56. It came with 3.08s in it and I kept the rims and tires from my red car. M&H 325/45/17s in the rear, 28" tall.
After I get all these few things finished, it'll go to Jon @ DBRods for a gear swap to 3.42s.

The reason i ask is cus i want to switch to a 28" tire on the street for traction but it would drop me to the equivalent of a 2.73 rear gear. Any idea on how much tq the car makes?
