APS TT C6 w/ upgrades
This 2007 C6 Z51 came to us with a stock LS2 and an APS kit w/ custom 3“ DP's and 3" exhaust with no mufflers, fuel system upgrades with surge tank ( unknown ), AEM single nozzle meth kit, AEM True Boost, Z06 body kit, Z06 wheels and a few other odds and ends, but was in need of some TLC.
The customer purchased the car used and has had many issues since with turbo failures, exhaust leaks, clutch issues and it ran poorly. We got digging into the car and found many, many issues that needed to be resolved and then some as we got deeper into the project:
• The fuel system had standard rubber hose on push lock fitting which was all brittle, burned or ready to crack.
• We found that an induction had come off on the driver’s side and therefore sucked lots of dirt and debris through the turbo which ruined it, packed the drivers intercoolers and unfortunately the motor saw some of this as well. The charge pipes were rubbed through on both sides from improper installation and tire contact.
• There were numerous burned wires and vac. lines.
• 1 broken 02 sensor
• Pass. side downpipe was leaking badly due to missing hardware
• Exhaust poorly adjusted and out of hangers
• Meth system installed incorrectly and therefore not functioning. Washer solvent was used
• The wiring for the meth, true boost & fuel system were a disaster.
• There was low impedance injectors with resistor boxes installed which 1 was broken. The injector harness was all hacked up as well.
• The torque tube input shaft was found damaged upon removal.
• 2 bolts missing from bell housing
• Radiator cradle only in by 1 of the 4 bolts
• Crank pulley wobbling
• Diff and trans seeping and covered in dirt/grime
• Air horns crammed in inner bumper
I think the above notes cover most of the issues…
The route of attack was to perform a leak down and compression test which surprisingly was OK. We then received the go ahead to move forward with the project. The list below is all the new items, repairs, upgrades we performed:
• PRC .650 kit (retained stock cam shaft)
• Comp pushrods
• SLP / PB crank pulley w/ ARP bolt
• GM input shaft, GM pilot bearing,
• DSS 3” driveshaft and couple kit
• McLeod RXT w/ steel flywheel
• GM slave
• AMS remote bleed line
• APS manifolds smoothed and ceramic coated
• APS Z06 intercoolers
• PTE Billet upgrade HP5830’s w/ revised intake tubing
• K&N filters RE-0930’s
• Flush and clean all inlet/charge pipes and intake manifold of dirt, grime and debris
• Readjusted and repair charge pipes. Install new SS couplers in the event of tire contact
• Upgrade AEM to dual nozzle and fab MAF delete pipe which houses nozzles and IAT
• GM 02 sensors with new extensions
• FIC 1000 CC injectors, repaired wiring harness with new clips and removed resistor boxes
• MSD wires
• NGK TR7 plugs
• Revised all fuel lines, fittings and relocated regulator
• Revised all vacuum lines
• Relocated breather catch can
• Designed a relay and fuse distribution block
• Rewired fuel system, meth, true boost
• AEM wideband with custom mounting in center vents w/ meth indicator LED and refinished center console
• M1 50/50 mix for methanol
• Diff and trans fluids serviced
• OEM horns
• Repaired radiator cradle and secured properly
• Lots of heat insulating to protect wiring, fuel lines and vacuum lines.
• 2 bar MAP and AMS Tune via HP Tuners
• Detailed
We wanted to stay safe with the car seeing that is had been thru some hard times, so boost was kept at a safe 10 psi. 93 octane w/ Meth
Results are on our Mustang Dyno are as follows (approx. 10% lower than a Dyno Jet)
584 rwhp / 537 rwtq
The turbo’s come on very fast and due to the car being on plain street tires its worthless 1st-3rd gear and depending on the road only gets decent traction in 4th. The customer picked up the car Friday 9/30 and was very pleased with it driving like stock and getting almost 30mpg on the ride home!
The car went to the track just 2 days later with the same street tires and little seat time, but he still managed an 11.2@133. I know he is working on getting some drag radials to get back out before the season is up to see how it will really run. I think the car is good for mid-lower 10’s at 135+.

thanks
We are not a fan of heat sleeve boots and if anything we would put the stock sleeves on if an issue occurred. We have a good amount of street and dyno time on the car with no issues prior to delivery.
thanks
This is base boost, so boost per gear would not work for his combo at this time. The customer is aware if he gets bored we can still turn it up some, but he plans for a motor first to be safe. I'm sure we will see him back in spring for some more HP
ha!
There is many, many hours in this project, so yes there was some costs involved along with parts.

Aftermarket sleeves are not a cure all for heat shielding. The fiberglass type sleeves will allow the wire or boot to be damaged if they are in contact with a hot exhaust, even though they won't burn they will transfer enough heat to cook what you are attempting to shield from the heat. The stock sheilds are as good as any aftermarket sheild and will actually work better because they aren't limp and and will hold their shape, where as a fiberglass style sleeve is and often will lay directly on the hot surface and lead to heat damage of what you are trying to protect.
Kudos to Larry@AMS for a job well done. You made a diamond out of a lump of coal!

I'm unsure if it went thru any owners after being completed, so I can not say if the shop is 100% responsible or not.
We look forward to working with you too on the upcoming killer C5 Z06.
The same guy, but never an owner and rather a very dedicated employee

use the [ yt ] [ /yt ] (no spaces) tags around the actual video ID number which is the random jumbling of letters that follows the 'v=________'

You're welcome, glad to help. I edited my original post to show the actual tags. Without the spaces, the forum engine hides them.
Anyway, thanks for sharing the details on a great and successful rebuild
