Thanks to a set of simple brackets, the need for an entire 03-04 Cobra Front Dress is no longer required!
To buy the brackets (pictured Below) contach Terry @ [email protected]

Above are the original design, im pretty sure this is whats made currently:

No need to swap timing covers, alternators etc.
Here is a pretty complete parts list:
Eaton Supercharger (Low miles preferred or ported even better)

Billetflow 3.4 or 3.1 pulley, non-slip upper pulley
LFP Quick Change Lower Pulley Kit 2003-04 Mustang Cobra 2#
or goto
Metcomotorsports and order Product ID: MMC0001 Supercharger Installation Kit

E 3.0
R 2.9
Stock Eaton 3.6 Upper with 2 lb lower = 25080537 Belt from NAPA
Eaton Lower intake

Stock Plenum

Intercooler

Intercooler Reservoir( stock works well)

Custom Bracket for Intercooler Reservoir

Intercooler pump #F8YH8501AA (new or used doesn't matter)


Intercooler pump wiring pigtail 3U2Z14S411BJA / WPT260

Intercooler pump bracket #4W33-8N500-A or make your own.

Heater coolant return tube:
for such a little tube it can be a pain...there are 3 ways to go about making clarence for the tube
Either smash the OEM one with a hammer so it clears the lower intake.
If you use the Marauder tube you will also need to plug the small coolant line that goes to the PCV valve fitting on the intake manifold.The Cobra tube does not have this fitting.

There is a lot of 'webbing' under the Cobra lower intake that can be removed to solve the clearance issue between it and the coolant tube. Go slow and check clearance without the gasket in place when the intake just touches the tube then you are done the gasket will add extra space.

or replace it with this one that fits properly:
Cooling tube F8ZZ-18B402-BA
Screw N807959-S309
Bolt N807309-S437

You will need to cut and weld to make a coolant crossover tube from the original in this manner;
Shorten the factory crossover about an inch in height and length. Weld up the end that attaches to the thermostat, removed and rewelded the mounting tabs to the botom of the crossover so they bolt to the heads, move the the other coolant hose nipple(the barb on the passenger side of the crossover tube) so it doesnt hit the belt tensioner.Make a tee from a couple of metal hosebarbs from the hardware store. The tee conects the upper radiator hose to the thermostat.Also either eliminate or plug the hose fitting that goes to the PCV valve fitting on the intake manifold.

swap brackets (conversion brackets)search Gortch on MM.net also 3-8mm x 120mm bolts and 3-8mm x 150mm got mine from Fastenal ,got them next day.

Take the top smooth idler pulley off the passenger side of the timing cover part number XR3Z-8678-BA and install it backwards on the alternator bracket.The alternator may need just a small amount of material removed to clear the pulley.
A ribbed idler pulley#F5RZ-6C348-A needs to be installed where the smooth idler used to be.

Cobra intake tube and MAF

Mafia

IAT sensor; DY-754 /pigtail; WPT-322 or use the Cobra sensor, just get the pigtail #3u2z-14s411-ssa (note, if the blower didn't come with the Cobra sensor you need to get one to plug off the hole anyway.

Here is a wonderful pinout for the MAF swap from 6-wire MM to 4 wire Cobra provided by Fordnut;
From MM > To Cobra
MAF P1 Gy/Rd > MAP/BAP/IAT2 P4 Gy/Rd Signal Return
MAF P6 Gy > MAP/BAP/IAT2 P3 DB/LG MAF Signal
EGR P2 Bn/Wh > MAP/BAP/IAT2 P2 Bn/Wh Reference Voltage
EGR P3 LB/Rd > MAP/BAP/IAT2 P1 Rd/Ye MAP Sensor Signal

If you use the 2 wire sensor then pinout is
MM>Lightning
MAF P1 Grey/Red > Grey
MAF P6 Grey > Grey

Throttle Bracket 2R3Z9728BA and Cable 2R3Z9A758AA or
use the original cable and bracket with one small modification
IMG00008-20091229-1632k.jpg


K&N RE-0870 Air Filter

Metco MAF to Air filter adapter plate
0218002312.jpg


39lb fuel injectors minimum

Belt tensioner 2R3Z-6B209-AA

Alternator Pulley F5AZ-10344-A, Motorcraft GP-712

Kenne Bell Boost A Pump 40amp

Ford GT supercar fuel pump

Heat Exchanger and plumbing

Fabricate brackets for heat exchanger.

Battery tray #F7ZZ-10732-AA and group 58 battery so you can keep your windshield washer fluid bottle.

new longer battery cable

EGR delete stuff.
Here is the 'kit' for those who cant/dont want to make one from scratch.

Just FYI, the pics are of a Marauder coolant crossover tube, the Mach and '99-'01 Cobra will be different but the same principles apply. It may even be possible to start out with a Terminator crossover and make the tube with less fab work than the Marauder requires. The top radiator hose is in a different spot.

Using 03-04 Terminator crossover requires no fab work on 01 Cobra.
