Got started on first phase of getting the twin turbos installed.
This is going to take a long time and will include fuel system upgrade as well
so be patient but watch for regular updates

I will try and post LOTS of pictures for all you picture crack heads

Parts to be used:
Ceramic coated BBK shorty headers
Garret T3/T4 60-1 turbos .48/.71 AR
dual 2.5" down pipes
Twin 38mm Tial wastegates
50mm Tial BOV
Treadstone Performance TT intercooler 6 X 26 X 3.5" core.

All going on to 357ci - 351W @ 9.5-1 compression and 12psi of boost.

I've started tearing the engine back down and cleaning up some
wire routing and test fitting where things might go.



Right now I really like the idea of the turbos being mounted down low
and fairly hidden to the causal glance. It would also make fitment to the headers
a butt simple straight shot to the turbos.

They are just sitting on the sway bar right now, but will be mounted up
and slightly forward from current location. Black rubber elbow is to mock up
for turbo CAI tubing.


I will have oil return issues that I need to talk to my performance shop about though
so we'll have to see .................... they just designed a kit for the '05-'08 GT's
using low mount twins also, so I think they have a solution available for oil return.

If any of yall have had any experience with low mount turbo oil return, please feel free to chime in

How are you going to get the oil back to the oil pan from the turbos?  Turbos are way low!!!

On Most turbo set ups, The Turbos have to be sitting above the oil pan and let gravity take its course, Unless your going to use a pump, to pump the oil back to the oil pan. 

Let me know!

Yeah, you use whats called a scavenger pump.
Little electric pumps designed just for that purpose.

good ones run $200-600

http://turbowerx.com/Scavenge_Pump/Exa-Pump/Exa-Pump.html

Can also use the electric pump to send the oil thru a cooler before going
back into the pan so the engine pump doesn't have to do it and your
not dumping scorching hot turbo oil back into the engine's oil supply

I think its a good idea! Sending oil through a cooler before going back into the oil pan.... So far your build looks great keep up th egood work.

Got the new fuel pump and filters ready to go

Running Socketless Hose for under the car from the fuel pump.
It's cheaper, easier to assemble, and doesnt leak vapor like braided stainless.

-12 feed from tank
-12 fuel filter ( 100 micron )
Aeromotive Eliminator Pump ( good to 900hp on forced induction )
-10 fuel filter ( 10 micron )
-10 feed to Fuel rails
-8 return




Glenn's Performance "sleeper" tank with -12 pick-up on the FRONT of the tank

Nice Fuel pump set up! What kind of fuel management are you planning to use?

I'm running an AEM computer with MAP sensor
will run 80 to 90 lbs injectors.

With the -8 return I'm not worried about the pump needing
an aftermarket controller.

I'm thinking down the road myself on a twin turbo setup for street use mainly.  I have thought about oil return too and thought about using some of my Holley blue fuel pumps after removing the small screens.  They would always be sucking, maybe using a resistor to slow them down a bit?  Don't know how much oil is flowing through them.  My '86 turbo coupe has a 1/2"? gravity line.

won't the oil pressure from the engine force the oil through the turbos no matter where they're mounted?

I believe I have read that turbos mounted above oil resevoir use different type of seals than ones that are mounted lower and the above type if mounted lower will push oil past the seals as return/outlet oil is under pressure then.  My thinking is use fuel pump as scavenger oil pump returning the oil to the oil pan.

The oil pump will always deliver oil, but the turbos
are not meant to have pressure on them from oil backing up
and it starts having to "push" the oil on the outflow from the turbo.

Thats when you start blowing out seals.

The oil scavenge pumps are designed to pump HOT oil
and will always pull a little more suction then is needed
without creating a vacuum to suck the seals in.

My performance shop just designed and has installed
several dozen low mount twin turbo kits for the S197 Mustangs
and they have an oil pump spec'd out and available that works great.

you really want to make sure you use a pump designed to remove
oil from turbos. They are readily available and made just for this purpose.
