    Well, as the title says. Anyone have input here? 1994 GT 5 speed Convertible.

    Here are my plans. I'm in the middle of piecing a full exhaust together, and it's probably going to end up with a flowmaster cat-back unless I can find a good price on a used magnaflow setup.. just can't justify or afford 400 for a cat-back... and as much as I love the magnaflow sound, flowmaster is the best bang for your buck as far as I've seen.

    So full exhaust...and I was thinking at the time of the exhaust install, to put in an air pump delete kit and get rid of that piece while I am under there.

    Then I was thinking about setting up a rear end rebuild with 3:73s.

    Then, I was considering putting an intake on it with bigger throttle body, and bumping the timing and running premium.


    Any input to all this? Am I way off base? These decent starter mods? Don't anyone try to shy me away from the exhaust, this thing is so quiet it makes me sick as it is... I want the rumble and if I get a few HP out of it, awesome. Definitely would like to give this car some more snap off the line.

    Thanks everyone!!

    Sounds like you have a grasp on things. If your looking for loud then a catback might not do it for ya. It will change the tone, but you need to get rid of the stock catted H-pipe to get some decibles. An off road H or X will help ya in theat department.
    ALso underdrive pullies along w/ the gears, upper and lower intake will be a step up in the go fast side of things.

    ok well I Just ordered a flowmaster american thunder kit, and I have some headers and an o/r X pipe lined up.

    doing upper and lower intake... in terms of engine work, do those give a noticable gain unto themselves?

    headers back exaust and 3.73 with give one hell of a more difference than headers back and intake, plus on a the good side getting 3.73 and having them installed is cheaper than buying an intake, elbow and gaskets

    Your on the right track. Exhaust, intake and gears are good "bang for the buck" items. Save your cheese on the T-body upgrade tho. No need to replace yet. Buy a short shifter for the $150 or maybe some shortie headers instead.... O0

    You can realize a good 15 to 20hp gain with catback and intake swap. The intake swap is easy. It is a good learning tool when you decide to do the heads/cam. The gears will pull the car into the slightly higher torque band too with these upgrades. If this car is NOT NOT NOT a daily driver go higher than 373's considering you are driving a heavy convert.

    i have a 94 gt vert, with smog delete,upper/lower intake,throttle body,CAI,h-pipe to flow master,bassani headers, underdrive pulley's, timing to 15 w/ premium, 9mm wires,poly/tubular control arms, polly motor mounts,tremec 5-speed, and 3.73 w/ a new clutch pack....and out of all of that the 3.73 was the best thing i have done to it so far, gears with the new clutch pack = sideways and acceleration :dancing6:....wish i have a blower/turbo though

    Headers are nice, but decide if you want long tubes or not. If not then get an off road h pipe and do headers later, underdrives are great $90 will give you a full tenth off you 1/8 mile time(i tested on 4 cars) Gears you will love(around .3 off the 1/8). Then the intake, last try finding a motorsport(cobra) so you dont have to buy the elbow or convert to the 87-93 style

    Dont start off with exhaust as far as mods go.. if you're going to do exhaust make sure you get a set of heads and an upper and lower intake plus get the car dyno tuned, if you put exhaust on the car is going to run very lean and you're not going to get much gains

    The restriction on the 5.0's are their tunes and their heads/intake if you're not going to get heads and intake and just do exhaust atleast get the car tuned so it doesnt run tooo lean

    Well, I'm not the only owner, and it will be driven daily... so 3.73 will suffice. I have shorty headers and an o/r X pipe lined up, just waiting for someone to get them off his car so I can buy them from him.

    As far as the gears go, I have a very good friend (mechanic) at a Ford dealer where I used to work, and he said he'd be glad to help me set them up for cheap.

    When I get the gears... I'm gonna get the Ford Racing 3.73s with a rear end rebuild kit.

    I'm working on an associates in automotive service, so I know my way around a car pretty well, however I have not taken manual drive train yet (will this fall) and as such don't know how to do gears yet.

    I'm definitely gonna get rid of the air pump, because getting rid of the cats, there is no reason for stuffing more air back there! Does that give a few horsepower gettin rid of that?

    Also, how worthwhile is bumping the timing on these? I've been told it wakes it up with 12 degrees and 92+ octane...

    Thanks for the input everyone.

    Okay, what I am saying is, is that worthwhile? Can you feel a noticeable difference?

    Okay, once I get the exhaust on the next item on the list is the 3.73s. Already have a friend lined up to help me put them in!

    Thanks

    I bought my '95 GT last April, but was going in and out to sea a lot, then was deployed for 8 months, so i didnt' have much time before i left. i've been home about a month, and here's what i've done... 3:90 gears, Aluminum Driveshaft, 70MM throttle body, JLT Cold air intake, Hurst Short throw shifter, Dynomax aftercat, Mac O/R h-pipe... I went with the H-pipe for now, because i plan on going with longtubes,(The stock catted pipe had a hole in it, it NEEDED to be swapped) i however have a wife and a 4 month old son, so my car money is limited... i'll save up, then get the Longtubes... next on my list is the pulleys, and then some appearance mods... i also picked up a set of '03 Cobra rims with tires for $400... Keep your eyes open for good deals, i got the JLT, the driveshaft and the rims and tires for $600 total.

    You're on the right track, just keep your eyes open... i'm a big fan of classifieds. LOL... my car will be built using used parts if i can find what i'm looking for.
