Looking for mod suggestions

[ka3nxn]

Hi Gang,

I have a virgin 99 Expedition AWD with a 4.6 Triton engine in her. I would like to to pep her up a little I'm looking for recommendations.

 

[Black_Exhaust]

38cc Trick Flow Twisted Wedge Cylinder Heads, .6/.6 crane cams, some new valve spring, titanium rods, manley flat top pistons... Oh you said a Little pep... You can't go wrong with a flash for the ecu, predator or superchips are all I've ever dealt with and I'd recommend them.

^^^^great if youre rebuilding the engine...but to ball on a budget...exhaust, programmer, intake or gots mod, tps senor adjustment

It all depends on your budget, but maybe the gotts mod, a tuner. but if you want real horsepower throw a supercharger on it, 4.6's can take boost

^^^true...

K&N Filter, GOTTS Mod and exhaust would be the first 3 easy and least expensive...and you will feel like your driving a different vehicle just by the sound of it.

and a programmer...

The programmer and gotts mod is the best bang for your buck, the tuner can add 10-30hp and the gotts mod increases throttle response......maybe tuner, gotts mod and then a larger throttle body so you can get the power to the ground quicker. I would say the programmer is the best bet for a noticeable increase.

The 4.6 you have is the PI if im thinking correctly so if you did a programmer, gotts mod, larger throttle body and an exhaust you should be able to stomp non PI 5.4's and 4.6's

but yours is a 2000! thats PI! unless you built up a 97 or 98 5.4!

Yes they were PI heads. TFS now so technically it non-pi heads. Right?

TFS is trick flow right? lol those are probably much better then the PI heads lol!

Yes Trick Flow heads.

I agree with what everyone else said above. But I don't believe ring and pinion gears were mentioned. A higher ratio can significantly improve performance. Unfortunately with 4wd it can be a bit more expensive as you have to do both the front and rear differential. If I had a 2wd expy it would be one of my first mods.

I was thinking about saying somthing but for the AWD you have to go all in and thats close enough to costing as much as a supercharger

OK not as much but its more then a programmer and such lol

Can someone tell me what a GOTTS Mod is?
