On3 Performance 1996-04 Mustang Cobra 4.6 4v Forward Facing Single Turbo System - 4vFF
"On 3 Performance is proud to release the newest Gen. 2 4.6l 4v Mustang
Cobra turbo system with forward facing headers. After almost a year of
developing this new On3 turbo kit, they are stocked and shipping daily. On
the same boost level we ran with the previous 1
st
generation kit, we picked up almost 30rwhp/50ft. lbs. mid-range. Most of
this is due to the new design and being able to spool the turbo quicker. On
5psi, we are making full boost in the upper 2000rpm range, that’s around
700-800rpm quicker than before. There is nothing like turbocharged power on
your modular 4.6 Mustang, bolt on and double the factory horsepower. With
this kit, we have had customers go deep into the 11’s and waiting on one of
our newest customers track details. Looks like we might see some 10 second
passes with our new 2
nd
generation kit on a stock bottom end 4v car. You will have no problem
trapping 120+ mph, we are trapping almost 121mph with our shop 2002 2v GT.
By designing a header that comes directly forward, we were able to
eliminate about 4’+ of tubing pre-turbo. This also allowed us to route the
tubing for the intercooler differently as well as the downpipe. So the
ground clearance was improved as well, it was never an issue but why not
improve it if we can? In order to drop weight with the kit, we also went to
aluminum intercooler tubing over the stainless, this lost almost 15lbs from
the 1
st
generation kit. Its also a shorter and more direct path which also has
shown us the benefits. In addition to the turbo kit, we added a few other
features to make the install easier and prevent issues down the road. We
designed a laser cut intercooler bracket kit that is manufactured just down
the road from our shop. While we were at it, we also had a turbo support
cut that allows the weight of the turbo system to be tied back to the
engine. This way the weight of the pre-turbo/turbo is supported by the
bracket instead of the actual tubing.
Each of our turbo systems come with our On3 70mm turbocharger which is
rated up to 700hp. Currently our 2v shop car has around 30,000 miles and 4
years of daily driving year-round. We have proven our turbos durability
over time and if maintained and installed correctly, its unbeatable for the
money. The turbo is proving the test of time and we could not be happier
with the results its provided us.
Into the kit details, each header is constructed of 3mm wall mild steel
which we have been proving over the last few years its durability on daily
driven cars. From the headers to the turbo is 304 stainless and 304
stainless all the way from the turbo back. We also went to a slip fit
downpipe instead of v-bands. This allows for more adjustment due to the lap
bands which is really needed. There is movement in the way the turbo can
sit so this allows the installer to be able to get a better fit. As
mentioned before, the cold side now is made from aluminum instead of the
stainless to drop weight. Not only that but it will also help with
dissipating heat and will allow for slightly cooler iat’s. Each tube on our
On 3 Performance cold side is bead rolled and uses t-bolt clamps for a
perfect seal and to prevent blowing a coupler off under boost.
Key Features:
– Perfect fit for AUTOMATIC transmissions
– Retains factory accessories – Air conditioning and Power steering
– Quicker spooling
– Forward facing turbo headers
– Less exhaust connections pre-turbo
– Turbo support bracket/Intercooler brackets included
-Better fit on the SN body cars to clear coil packs
– More simple design to eliminate tubing
– Easier to install and adjust the kit
– Maximum ground clearance
We have shop cars with each of our kits on them and the mod motors respond
to boost so well. They are so reliable and drivability doesn’t get much
better. It’s a good feeling on a 90 degree day to put the windows up and
crank the air conditioning to full blast. Whether sitting in traffic,
cruising, no heat issues and still drives like stock. Without hesitation I
would personally get in my car and drive it cross country, its been that
reliable and we have proven it over the last 3 years.
Over the time we have sold our turbo systems, there are customers close to
800rwhp on stock heads and cams with our turbo system and 76mm upgraded
turbo. A quick YouTube search will net you quite a few of these customers
and physically see the cars in action.
In order to run the turbo system, you will need to run our turbo tubular
suspension kit. Also there will be several upgrades you will need to make
for fuel delivery and air. Those upgrades are available though us and you
can select from our list when checking out if you need any of these items
included with your purchase to make it a full system and as complete as you
need it:
We get a lot of questions about daily drivers and is that even possible.
Well the owner of On 3 happened to daily drive the turbo 2v design car for
a few years actually. It didn’t matter the conditions and this thing has
gone strong since day one. Its still in use here and the stock engine
LOVES boost. The car has never had an issue with temperatures, you can be
driving mid summer and 100 degree day with the a/c on and perfectly fine.
Or on the other side of the spectrum, a February blizzard and plowing the
roads with the front bumper….poor car! This is no joke, the car was a true
daily driver for years and this was from FEBRUARY 7, 2010. The car was
built by us in ~2008 and still today, Feb 3, 2016, its being used by the
owner of On 3 as a daily to test new upcoming product. The 2v & 4v mod
motor engine is truly a pretty impressive machine with a good tune and not
getting carried away with boost. This has always been kept to 6-8psi for
street use. "

In order to run the turbo system, you will need to run our turbo tubular
suspension kit. The Cobra’s also have a oil cooler built into the factory
oil filter assembly at the block. You need to either trade or pick up the
2v oil filter plate that bolts to the block. The Cobra ones generally sell
for $100~ so most 2v guys will trade and pay cash. Also there will be
several upgrades you will need to make for fuel delivery and air. Those
upgrades are available though us in our accessory kits that include:
