Fun cars. My parents gave me a 1994 GT Convertible back in 1999! I recently pulled it from from the garage after sitting for 9 years! I have been using this Covid-19 free time to bring my old girl back to life. 3:73's, high flow 2 cat h-pipe and a cold air from back in the day; I fell back in love!

[@maxjones9139]

I’ve been doing the same thing! Mine had a mouse nest in the hvac against the evaporator. Had to remove the dash. Major pain but I took the carpet out too it had soda stains. Installed some dynamat and am in the process of replacing the top hydraulic lines and actuators. 94 gt vert.

[@bertryan6401]

I have a 94 mustang gt just paid 1,500 for my T5 rebuilt and flywheel needed to be resurfaced. Still a lot of work to do.

[@dylnfstr]

I miss my SN95 so much.

[@bertryan6401]

When i bought the car it came with Shorty bbk headers that go into 40s Flowmaster sounds loud

[@augustinevela9892]

New to channel. Somehow algorithm yielded your sn95 channel. I have a dt95 and swapped block for an 89. Blood sweat tears!!! Roller rockets, Gt40 heads, new headers, 24lb injectors, Gt40 upper/lower with 1 inch intake raiser. Now hood don't close!!! This FN car is the bane of my existence. Too much KZbin and monsters. Momma's had it!!! Thanks for all info shared. TC and God bless...

[@GrandTouringConcepts]

That sounds like quite a bit of work you've undertaken. For hood clearance I would skip the 1" spacer and run it as is, you'll make good power. Explore the rest of the channel and thanks for watching! - Darren

Enjoyed the video keep them coming

[@94OJGT]

this is great to hear, i have a 94 mustang gt thats been sitting for the past 10 yrs. was my first car and i decided to get it going. has ported stock heads, ported upper/lower intake, f303 cam, bbk longtubes to an xpipe, 3.73's, underdrive pullys, i was curious what it will make on a dyno. if i had a guess id say 250rwhp but who knows. maybe more

[@rzjk301]

You hit the nail on the head on this one. You brought back my memories of me racing a friend, who had a 1995 LT1 camaro. I have 373's, mac long tubes with H pipe, Flowmasters American Thunder cat back. It was a drivers race. His car was an auto and mine is manual. Now 23 years later my car has a Tremec 5 speed, 347 CHP small block voodoo cam, lightning 90MM, 42 lbs injectors, Edelbrock RPM intake, edelbrock 6037 heads, 70MM throttle body, My only problem is traction...

[@GrandTouringConcepts]

It was a really interesting time on the streets even 15 years ago, and I'm glad the story brought back some interesting memories, I have to finish how my tale turned out sometime. Your build sounds like a stout performer, and for my Kenne Bell build, I found traction with a set of R-compound Toyo R888's. Thanks for watching and the comment! -Darren

[@rzjk301]

I rode around with Nitto drag radials for a year or two. Not realizing I was tearing up my torque boxes. I had to weld in some torque box plates to repair and strengthen the torque boxes. Thanks for the advice.

[@alvin7089]

@@GrandTouringConcepts Exhaust note sounds amazing bro. Was the Exhaust in the video the same Exhaust setup you mentioned in this video? And any idea on what compression ratio you ran with the blower?

[@trackpackgt877]

My 2010 track pack GT came with Factory headers and a h pipe I thought that was pretty cool of Ford not to mention numerous other things only available to the track pack but I deleted the mufflers and it sounds awesome now

[@rave112]

I am a backyard mechanic with basic tools. Any advice for tackling an exhaust job? Especially when it comes to the headers.

[@GrandTouringConcepts]

I started as a backyard mechanic and still do the huge majority of my work on jackstands and appreciate where you are coming from. I done adout a dozen full systems and several sets of headers, so I do have some advice for you. Lift height, you need at least 18" of working room under the car, use tall stands or other safe methods. Sawzall, this is critical for chopping out the over axle "dogleg" the aftermarket system is generally sectioned for easy install. Work cold, header/pipe burns suck. A cordless/air impact does speed up the job but is not mandatory. Socket set with various extensions and open end wrenches are minimum tools. O2 sensor wire extensions, if doing longtubes you will need to cut and extend or do a plug in solution. That should get you started. Thanks for commenting and hit us up on facebook or IG to share your build. - Darren

[@luanaaraujo2159]

Hi fellas, do y'all have any installs of and IRS exhaust install on an SRA car? 94-2000 preferred.

[@paintballalienindy09]

I got the brakes off an 04 cobra on my sn95 and they work so much better

[@headlesnorseman701]

To be fair. I’ve owned an lt1 6sp f body. There was something to those cars. I think they were somewhat underrated power wise. And they had a massive useable powerband that you can’t really visualize until you drive one. It would put a lot of cars to shame even more modern ones. I could just imagine if they had spared a few hundred lbs when designing the car. It was certainly heavy

[@nedaCFilms]

The 6-speed LT1 cars were monsters! They made eyeball flattening torque but what really stood out was the powerband you mentioned. Especially after opening up the exhaust and intake with a decent cold air kit like the Moroso or FIPK from K&N. They just pull and pull and pull lmao!!! I mean the suckers never stop revving. It really was a big deal back in those days around mid '90s (before the LS1 shook things up lol) I've owned more Camaros & Mustangs than I can count on my fingers and toes in my almost 50yrs on earth, and the fastest top speed I've ever "driven" (been faster as a passenger in other cars lol) was in my "bolt-on modded" LT1 Camaro Z28 w/ 3.23 gears. Buried the speedo at 150mph and the sumbitch was still pulling! If I had to guess I believe I had to hit around 165mph...….. anyway, those LT1 models are very underrated. Keep in mind that they had quite a span/range in rear wheel hp through their 93-97 run, with the earlier 93-95 automatic cars being the weakest and the 6-speed cars making more power, but the later 96-97 manual 6-speed models made some serious power. They were the underrated cars that could put down their advertised hp to the wheels. The early 93-95 automatic cars only made around 230hp to 240hp to the wheels. The 6-speed cars making more towards 240hp to 250hp. Now the 96-97 LT1 with 6-speed tranny put down more than that to the wheels and I've seen 96-97 cars with full exhaust, no catalyst and decent cold air put down LS1 numbers! I have quite a few LT1 dyno videos on my #MustangTown channel if interested.

Solve your 5.0 kenne bell 👍👍👍👍👍need help for my sn95 convertible I have a kennebell love to put it one

[@sanjeevbasi3271]

Hello, I just came into possession a 1995 GT, I’d like to do work to it such as this. I am looking at ordering exhaust stuff, I see shortie and long tube for headers. What exactly is the difference and which one is better. My car is automatic so I’m not looking to do to much power upgrading but I’d like to make it pretty

[@chrisdavis7883]

i had a 98 gt that had 6 cats stock. got rid of that...

[@Macho_MT]

@GrandTouringConcepts was the Hp gains on the stock ECU without a tune? Or was it chipped or a stand-alone?

[@GrandTouringConcepts]

This was untuned, timing was advanced 2 degrees total.

[@jrusted5.031]

I got a 94 and I'm trying to put exhaust cutouts I'm trying to keep the stock headers what is your opinion on that

[@dannypadilla7136]

It's alarm setting off loud, but sounds SICK!

[@bignhale3379]

I got long tube headers on my sn95 but need new exhaust how do I find out what will fit? any help?

[@GrandTouringConcepts]

The best bet is to check what brand of headers you have, most offered a matching midpipe which tied to nearly any cat back. If you can't determine what brand they are or have no luck, most muffler shops can build something to fit. Hope that helps, thanks for watching! - Darren

[@302hobronco]

Was there any computer tuning done to get the results from the exhaust or is this all off the stock tune??

[@GrandTouringConcepts]

This is all off the stock tune, before and after the MAF based system of the EEC 4 will effectively meter the additional air and adjust. The system does not require tuning unless there is a change in MAF sensor, injector size, or camshaft (driveability). There are a couple extra points usually in adding a bit more timing advance and dialing WOT fueling to that magic 12.8 - 13.3 range but it's not required. Thanks for watching and commenting! - Darren

[@302hobronco]

@@GrandTouringConcepts thanks brother.

[@minxsykitty]

@grandtouringconcepts How did you make the EGR delete work? any advice is appreciated

[@GrandTouringConcepts]

This is a bit of a challenge these days, in my application I used a TwEECer to turn off the EGR function, and simply capped the tube. There are some other resources like a megasquirt and custom chip tuning which have the function but the options are becoming fewer, and chip tuners are reluctant to make changes which run the risk of action by the EPA.

[@minxsykitty]

​@@GrandTouringConcepts looks like maybe I can stil get a TwEECer online, thanks for the help!

[@MCrelationz]

I actually do have a question if you could answer I personally do not like this specific body style of mustangs just my opinion I love the 99-04 styles. I looked up the 99 cobra and it says a 4.6 v8 with 320 horsepower is that true?? Ok nevermind I am pretty sure it is true I just can't find any cobras on the Facebook marketplace haha

[@GrandTouringConcepts]

The 99 Cobra was rated at 320 hp but did undergo a recall to address the issue with it not making advertised HP. This revision is the reason why no 2000 SVT Cobras exist (except for the very different Cobra R). Production resumed in 2001. The nearly identical powerplant can be found in the 03-04 Mach 1.

[@dominicoconner1973]

Did you have to do any tuning to your ecu? I have heard that the computers don't respond well to modifications, at least not like the fox bodys.

[@GrandTouringConcepts]

This modification did not require any ecu adjustments and made no negative impact to drivability. The 94/95 ECU does have a couple of odd behaviors when a cam change occurs but aside from that is essentially the same basic calibration as a Fox with a few additional perameters. Thanks for watching and commenting! - Darren

[@nedaCFilms]

Unfortunately when the LT1 Camaro and Firebird models came out in 1993 they beat the hell out of the 1994-95 Mustang GT as well as SVT Cobra models lol. Really had to have the 96-98 SVT Cobra models to hang with the LT1 cars in the mid '90s. Lucky though you had a 5-speed model and he had a heavy convertible automatic lol. The 6-speed LT1 cars put out quite a bit more power than the automatic cars, especially the later 96-97 manual cars. I'm a big fan of Mustangs and Camaros. I love all American Iron #V8ponycars equally, though my heart is extremely soft for Mustang lol, but honestly asking me to choose between my Camaro or Mustang is like asking me which one of my kids I love more lol. But that gives me an unbiased honest opinion of these historic automotive icons, and I try to bring that to my #MustangTown channel. Btw, where are you located Darren?

[@GrandTouringConcepts]

I enjoy the historical rivalry between the Mustang and Camaro worlds, and feel that sort of thing is absolutely necessary for best development of a car. Stiff competition gives very good outcomes. Its like the on track battles between the 95 Cobra R and the Trans Am, the TA had the advantage of years more development and piles of spare parts, whereas the Cobra R teams complained of late deliveries and few parts to survive a season. We are located in Alberta, Canada and I will have GTC sub to your channel. Great discussion all around! - Darren.

@MustangTown/V8ponycars you secretly love one of ur kids more then the other I personally got my mother to tell me witch one of her grand kids she loves from 1st-last

[@angelonicassio7131]

What gears did you use?

[@GrandTouringConcepts]

I used a set of Ford Racing 3.55's for a balance of acceleration, top speed, and highway manners. Thanks for watching and commenting! -Darren

273 gears ..great videos though

[@KnightsForge]

If you're still answering, I have some problems with my 95 gt, if you could message me back please

[@jameshail3079]

Good video but the major of videos are on 5.0. While the majority of sn95s are 4.6 liter.

[@hurtzz-lz5gl]

Bro. Never sell the car.

[@starrdogchamp1]

if you do a video on a sn95 it should be on the 4.6 not the 5.0. why? because 94 to 95 sn95 as a 5.0 so essentially all you do is follow foxbody engine upgrades since the are the same. useless for my 96

[@GrandTouringConcepts]

Not entirely correct, the SN95 5.0L cars are far different from the Fox beyond what is under the intake and above the oilpan. Chassis, engine management, ignition, and cooling system are all quite different and because of the "same as a Fox" misassumption makes the first SN95 cars very important to the series. The 5.0L GT cars in fact outnumber (138,094 over 2 years) the non-PI 4.6L production (125,231 over 3 years,) which make the modular the odd duck out. We have data available and planned into production for presentation but since we have never had a 4.6L GT available to the project for more than a day, it is difficult to gather the hands on perspective and footage. We are on the active hunt for one however, and will bring the tech in the future. Thanks for watching and commenting, and I would be curious to hear what topics on the 4.6L most interest you. -Darren

[@headlesnorseman701]

Grand Touring Concepts love the scientific approach. I’m hunting for a decent 94-95 right now. I never knew they came with the 5.0 until I saw your videos. I feel like as a car guy I should have known this sooner

[@rogerwatson5995]

If only Ford was smart enough to bring back the SN95s they couldn't build them fast enough Instead we get Mustangs that look like Nissan Limos its Sad but True take a close look at a Nissan and blow it out big put Mustang taillights in the rear and you have what we have today UGH😢

[@gmailuser3247]

My stock fox a9l made 224whp 301 tq on dyno far superior to my buddys sn95 they are not Tru 5.0 experience
