Twin Turbo ZO6 by Speed Inc. I'm starting the twin turbo build on my ZO6 so I thought I would post some pics and info. I will scale the car before/after to have an exact weight difference.
Here is the basic parts list-
427ci engine, World Warhawk block, LS7 crank, Callies compstar rods, CP pistons (coated), pvd coated stainless top ring/ductile second ring, coated bearings.
ETP LS7 heads, 6 bolts per cyl, PSI valvesprings, Xceldyne retainers/locks, Smith Bros pushrods, LS7 rockers w/harland sharp bearing upgrade, Comp Cam hyd roller, Morel link bar lifters. LS7 intake manifold.
Modified LS7 oil pan w/extra pickup going to external -12 a/n port. Internal volume reduced. Belt driven 3 stage external pump. 2 stages for turbo scavenging, 1 larger section as an additional scavenge stage to the engine (hence the extra pickup in the pan).
APS twin turbo system w/ceramic coated manifolds and turbo housings.
McLeod RXT twin disc clutch and Quick time bellhousing.
Driveshaft shop axles/hubs, diff output shafts, driveshaft.
RPM Level 5 T6060 Thanks RPM!!!
Eboost 2 controller w/gear based boost control.
HP tuners 2.5bar Speed Density operating system.
I'll update this thread with info and pics as the build continues.

Man what a setup, I can only dream to have something like that someday!! With Speed Inc.'s reputation I'm assuming well over 1k hp at the tires on pump gas is expected right ?

Thanks guys. As far as the eboost2 look under the "switch logic" section of the manual.
You can have 4 set points triggered by external switches. Basically I'm going to build a mount for microswitches that are triggered by the shifter which will allow a different boost level for each gear.

Can't wait to see fuel system details!!

Sounds like an awesome build.
However, isn't that Warhawk block a little much for those little APS turbos? I could see if you were doing a custom kit with some 76's. But those GT35R's won't be able to push more than high 9's to 1k at the tire on a 427.
Just wondering if you were planning on custom fabbing a kit for this motor in the future since it was such a crazy build?

The warhawk block probably wasn't necessary but I really like the idea of 6bolts/cyl and prefer overkill to marginal.
There have been a few cars built with the APS ZO6 twins that made over 1000rwhp at 16-17psi boost so it seems to be very efficient and likely capable of 1100 at the tire.. It helps that aps makes their own housings and chose a large 1.06 exhaust a/r.
