Twin Turbo TA Upgrades 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;
Turbo kit;
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)
After the upgrades;
Soon after getting on it for a bit, the trans had some......... slight issues lol
Rebuilt the tranny with a stage 2 kit, and installed a RPS Twin while I was at it.
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;
new valve covers (doing coil relocation as well) welded -12 bung for a catch can and painted black.
billet black bovs came in as well as the intake;
Getting the new cold site setup;
Had to make some brackets for the fuel rails I had;
Custom water vapor system I made;
Intake on;
catch can setup;
still got a few things to do.... I'll update here in a few days.

I was wondering what ever happened to that twinturbo build when it was started by the previous owner. That's not the same car which the turbo kit was originally built for, was it? Anyway, judging from your previous build, it's good to see that you ended up getting it.

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?
