07 MS6 Big Turbo Build

[mitchellbuehler]

Hey guys,

I've got an 07 MS6 that I've had for a little over a year now. About 5 months ago a screwdriver bit found its way into the motor and destroyed one cylinder, so I took that as an opportunity to buy a new car, build the motor in the speed 6, and go full send with a big turbo build. Aiming for at least 500HP with the current build, may shoot for higher in the future once I've got a few thousand extra to drop on an even bigger turbo and supporting mods.

Here's my (power/performance) parts list:
Manley H-Beam Rods
Manley Platinum Series Pistons
Corksport Cams
Corksport Injector Seals
JBR BSD
JBR Oil Pan Baffle
JBR RMM+PMM (Trans MM & Rear Diff mount in the plans)
Damond Motorsports EGR Delete
King Bearings Rod+Main Bearings
Darton Dry Block Sleeves
ARP Head + Main Studs
NGK IX Iridium 1 Step Colder plugs
ACT 6-Puck Sprung Clutch, Heavy Duty Pressure Plate, Streetlight Flywheel
ATP GTX3076R Turbo Kit
JBR Tru-3.5 Wide Path Full Aluminum Intake+TIP
Semi-Custom FMIC with 600HP capable core
JBR 3-Port EBCS
Bosch 3.5 Bar MAP Sensor
Kozmic Motorsports 6th Port Injection Kit
Autotech HPFP/CDFP internals
Deatschwerks DW300c Fuel Pump
eBay 3" Catless DP, custom 3" catback exhaust
Cobb AP
Any other smaller/less important pieces I'm forgetting

I've already finished building the motor and getting the trans+engine mounted back together, at this point I'm just waiting on the rest of my parts (maily turbo, intake, 6th port injection kit) to come in to finish the build.

Do any of you have advice on any other parts I should/need to get? I do plan on getting a quality turbo manifold and intake manifold next, as well as adding full-on port injection. But that's a lot more money and is not a priority at this time.

Will absolutely update this thread and post pictures as I make progress!

nice build so far. Pictures are welcome.

Since you already spent for an ATP flange, you may wait to upgrade manifold and turbo flange together to benefit of using a larger size.
Is your gtx a Gen1 or Gen II?


Did you get the ARP2000 or larger head studs for your power goal ? I have similar power goals and i asked myself but i did install new factory bolts.

For the fuel pump you can get some tip at the end of this build. He installed a separate pump for the port injection on the other top hat. I like the idea of keeping the dizi fuel setup as per factory and add a completly separate setup for auxilliary injection on the same tank.....

Thanks! Pictures will come once I'm out to work on the car again after finals, it's currently in my roommate's garage out in the country about 1.5 hours away.

I just went with the cheaper ARP head studs on Edge Autosport. They're probably not the larger ones, unfortunately, but time will tell if this ends up being a problem I guess.

Once I switch over to having 4 additional 1000cc injectors with a Port Injection setup, I'm definitely going to be doing a full aux fuel circuit, but for the time being I went the cost-effective route and opted to beef up the existing low-pressure side of the fuel system.

Appreciate the encouragement, excited to get this build put back together and off to the dyno for tuning!

Also forgot to reply - Gen 2 GTX. I'll wait to get a bigger/non-stock flange manifold until I eventually go with a Precision 6266 turbo at some point in the future.
