I was wondering who may have some good recommendations for my 02 GT Conv. on a new throttle body and plenum to get rid of the factory. I am upgrading to the K&N CAI and was unsure about these changes.
Plenum/Throttle Body Recomendation

I was just throwing my opinion out there man. I also heard they go well with f/i so I thought op might be interested in it if he wants to go that route in the future.

Open up the exhaust first, 2-1/2" from the manifolds back--catted or o/r H- or X-pipe (it doesn't matter from a performance perspective), and 2-1/2" catback.
Then buy a tuner, or "tunes-for-life" or whatever and get rid of the crappy stock tune. Even an 87 octane custom tune will bump the timing by 2° to 3°, and lean out the mix at WOT. Load a tune optimised for the highest octane fuel your are willing to buy, around here 93 is still only 30¢ more than 87; that's a whopping $4.50 per tankful, have a couple fewer beers or latte's between fill-ups and enjoy the added power.
These two changes are will wake up a stock GT.
Then change the final drive gears, 3.73:1 or 4.10:1 are popular--I won't get into the desirability of either. The tuner will let you correct the speedometer.
Next install an aftermarket upper plenum and a 70 mm TB. As explained in the link I posted above 70 mm is plenty for any n/a 2V setup, and it maintains a higher charge velocity at high RPMs.
An aftermarket CAI is nothing but eye-candy, if that's your thing go for it but it will not add a bit of power as, as was said in a previous post, the stock intake is a CAI and a very good one at that.
Next if you are the type that enjoys a performance car look at UDPs, aluminum driveshafts, lighter flywheels etc. These will make no difference unless you are one that always shifts at 3000 RPM, however if you are like me and wind that sucka' out now and then reducing rotating mass will provide a meaningful gain on acceleration.
Almost anything else--aftermarket COPs, fancy-àss spark plugs, air filters, etc.--is a waste of money...

Depending on your application I'll suggest either 70mm or 75mm no more than 75mm if you're bolting on only. BTW i got a nice 70mm BBK throttle body for sale. is new never been touched for a reasonable price. PM if interested.

Ya I will definitely let you know. I can always get a new filter if the old one doesn't have much life in it left.

Ya im definitely looking into having a turbo put on my car. This is why I want to upgrade the air induction section of the motor to help for added performance. I wanted a supercharger but I dont have the ability to do any inside work on the motor to upgrade the crankshaft and other internal components for that much power to a stock engine.

You run the risk of blowing the motor with a turbo and a sc. Just keep the power around 350-375 and you won't have a issue.

I went with the dragon 75mm and plenum.. I threw it on n/a first just because i had it laying around..
I have no complaints.. Seems to be a little quicker on the throttle response but... its honestly not worth the 200+ bucks unless you are going with a blower... Hopefully i cant tell the difference when i get this s/c bolted on

I havent heard anyone with problems on a mustang gt with a turbo... as long as you dont have the boost on it maxed out.

"Throttle response" is quicker because for a given amount of throttle pedal movement you are opening a larger hole, wider. As we do not always "floor it" (many drivers do not ever do so) this is to a point the same as would be accomplished by depressing the throttle pedal more with a smaller TB...
Yes, that is the predominate problem people have with turbos, and superchargers, on the 4.6L 2V engine. Most often the rods let go someplace after 420 rwHP. From 375 rwHP up engine life is degraded, assuming of course that you do make regular use of the power...
