EI-03-GT

I have a little part list and i was wondering if I need to add anything on there. if there are supportive mods that i should add on to my list for my 03 mustang gt. I have around 70K miles on it now and for the most part it is bone stock.


Comp cam shaft XE278AH
Pacesetter LT headers
SLP catted X pipe
SLP LM2
Professional Products throttle body
Professional Products Intake manifold
Professional Products Intake Plenum
AFE cold air intake
Lash adjusters
Rocker arms
Ford racing 3.73 gears
Patroit Stage 2 cylinder heads

That is about it. Will a SCT tuner with a cutstom tune be ok for the tune for the car or will i need to take it into a shop to get a actual tune? Should i upgrade to 24lb injectors or am i getting ahead of myself?

w/ heads AND cams you wouldnt be ahead of yourself getting better injectors and a dyno tune. i wouldnt trust a canned tune with heads and cams.

Will I need to change the clutch and flywheel or will the stock set up hold up?

The Flywheel doesn't matter too much unless your are going with an Alum driveshaft as well. Aluminum Flys tend to wear on clutches somewhat prematurely as it takes a little more throttle to get going....

Your stock clutch should be okay as long as your RWHP stays under 350. If it goes over that, then a SPEC stage 2 plus clutch would be in order.

As far as the tune goes, Dyno is always better especially with a cam, head and injects upgrade. Dyno will also indicate true torque/hp as well.

when changing the heads is there a need to change the Lash adjusters and Rocker arms or can i just the ones from the stock heads and reuse them?

Depends. Are you using the same cams? If you are, then you can get away with it -- if your smart about it.... Relocate them in the same order. New cams, you should change the lifters. As far as the rocker arms, just inspect them. If they look good, you'll be okay.
