what a difference!

[chiaronate]

hey, i used to have a 1994 mustang gt with automatic transmission and recently traded in for a 2000 mustang gt with manual transmission. just wanted to say it feels much more refined. the suspension is smoother, and at the same time it handles better. acceleration is a night and day difference and the mod motor feels alot smoother and eager to rev. wow, what a car.

Welcome to the Modular motors. I hope you enjoy your stay. My fiance has a 2001 GT. REally a neat little car. I am in the middle of doing a P&P job on her intake. What are your plans for mods?

[chiaronate]

not too sure yet, i don't want to change many things. i'd like to keep the 3.27's. possibly exhaust work in the future, but nothing noisy. mabey a bullitt intake manifold also. i've read in a book that the bullitt intake manifold makes only 5 more horsepower, but torque peaks at a much lower rpm. something like that would be good.

first off I will have say congrates
and welcome to the mod motor world

is there a reason you would like to keep the 3.27 gears?

and if its gas(MPG) then I will tell you this I have 4.10s and I get better MPG around town then I did with the 3.27s and highway I lost maybe 2 MPG

if looking for a cat back but not to loud then look into magnaflow
but remember on a stock n/a car a cat back wont give much power if any just sound.

Welcome to the Mod world where things are getting better and cars getting faster.

3.27's are a good all around gear, i'm happy with them. i'm thinking maybe short-tube headers and intake manifold, along with mass-air meter and throttle body. by the way, what would be the right sizes for mass-air and throttle body for more horsepower/torque. i'm going to the book store to see what i can find. i knew alot about the 302, it's like i'm starting over with the modular. is the exhaust manifold on these motors efficient?

[blue00gt]

The Bullit intake is really expensive for very little gain on a stock car. Also, shorty headers are almost not worth the price and the pain of installing. Throttle body won't give you anything unless you get an aftermarket upper plenum. The more effective bolt-ons for modular GTs are underdrive pullies, timing adjuster, x- or h-pipe, plenum, longtube headers, etc.

[chiaronate]

i was looking through a 4.6 performance book and wasn't impressed with the performance gains for throttle body, mass-air, exhaust etc.. i think i'll leave the car the way it is for now. i also looked in a mm&ff magazine at a camshaft test. the aftermarket camshafts were pretty much the same as factory, with 10 more horsepower in the higher rpm's. definitely not worth the money and hassle. i'll wait to see if something decent becomes available.

[4.6LitreGT]

i would say that there are already decent mods available.

the motors dont need help with mass air becuase it is sufficent for the car as it is, go with the mods listed above, or in my sig, and i think you will be happy and not break the wallet.

the mods they listed are definetly worth while. i dont think you could take a 5.0 and spend 1300 bucks and run 13.50s N/A.

Plenum and TB - 350
X-pipe & Catback - 450
Shifter - 160-180
4.10s - 350 installed ( the other parts can be installed yourself)

I agree 100% with blue00GT. Also you may want to look into the jlt cold air intake. it is only $150 with GREAT GAINS!!! www.jlttruecoldair.com is his website. The GT CAI is not on there but will be on there next week.

[chiaronate]

my car does low 14's from the factory, mid 13's isn't much of a difference for all that work.

[Fat0eknee]

a mid 13 is a hell of a lot of difference ..i wish i could run a mid 13 with my car all motor

[chiaronate]

well, of the things mentioned above, i would possibly change the throttle body and plenum, and also the exhaust system. i'd rather not deal with gears. i had them done on my 1994 mustang and the backlash was out of adjustment, causing them to make noise when i let off the gas. 3.27's are a good all around gear anyhow, and i won't be racing at the track. does anyone have dyno numbers for aftermarket exhaust and throttle body/plenum? any magazine article quotes?

[4.6LitreGT]

Write-up on Testing TB and Plenum

i've read on modulardepot guys with longtubes, midpipe, catrback, pullies, plenum and tb and CAI and a tuner(diablo/SCT) are pulling around 270-280 rwhp

Welcome to the board by the way....3:27's are Granny gears!!!

Why? the 4.6's power band is more usefull in the upper RPM range...3:73's OR 4:10's will get you there much quicker. As you gain more experience with the 4.6 you will know that GEARS will be the best bang for the buck, besides supercharging...

Cams are not a bad mod either...not only should you look at the HP gain, look at the operating range / power band at which they generate HP/TORQUE...much different / efficient than stock.
