Building Custom Firewall To Fit The 5.0 Coyote Engine On The 1965 Mustang ! 

Well, at least he hasn't cut it in half yet.

Getting closer to wall art every panel you remove 😱

Here we go again I hope there is room behind the old shop for this 1 when it's done

This turned from "it has no rust" and "I wanna keep it stock" to "twin turbo coyote" and "roll cage" real fast

The plan is, there is no plan.... Another classic car to the scrap heap...

You need to get a bread roller and bread roll the firewall. The indentation will make the steel stronger. It will also come in handy when you make other custom builds

I personally would have kept the firewall, you just lost reference for the steering column, pedal holes, booster, and hvac. Could have bought all aftermarket parts that utilize the stock location and just smoothed out some sections of the firewall. Hoping it comes together. Keep plugging away on it!

Not hating, but I’m sure the factory firewall had those curves and bends for a reason. Same reason you shouldn’t use a flat piece of sheet metal for floorboards, inner rockers, and other structural areas of a car’s chassis.

bro please stamp your firewall it will add strength to it

I had high hopes for this build, but I'm not sure about the firewall decision. Don't want it to turn into the last attempt.

We have been down this road before. It didn't end well then, and it probably isn't going to end well this time either. Twice as heavy, half as strong.

Boy do i miss the old "frame pulling" video's! These custom build video's are like watching a 13 year old figure out how to custom build a car

You definitely need a bead roller to add strength to the firewall and other panels that you are going to build. And also it would look better with some beads... Cheap HF (also Eastwood, etc.) Chinese Bead Roller with hand crank work fine for what you do.

Nice to see the build moving forward. You should consider some firewall indentations using a bead roller. Check "Make It Kustom" channel. He has good fabrication tips. Also, consider using the Fastback roof and sides, since this is a custom build.

Definitely your car and there is nothing wrong with experimenting, but the engineering is going to bite you in the ass the same way it did with the last car.

I would of liked to see the firewalls to have some bead rolling as it adds strength. Also since it is a full custom I would put subframe connectors but the style that goes through the floor and is welded to the floor and the front and rear subframes

I keep flashing back to how perfect the car is and how it hardly needs anything.

I know it's your car and i appreciate the creativity to make something custom, but i think you should've kept the firewall and the aprons looking as factory as possible, even if that means modifying OEM sheet metal, that would result in a better look and will be easier to install A/C down the line if you want, some companies sell bolt on modern A/C kits that use factory mounting points, if you modify the firewall too much you won't be able to use that, just my 2 cents...

Are those flat surfaces on the firewall going to flex and make noise?

Really hacking this thing up. Think we have heard this story before.

Those indentions you see on the original firewall actually give it more strength. I forget what they are actually called, but it's a simple machine with a wheel on it that presses them in. Only problem now is that it's already been welded in and no way to do it now.

If others have already installed a coyote with the stock firewall, i question why he thinks he needs to reinvent the process. I hope it works out.

Not to mention you took out the area where the bell housing comes up. you definitely screwed this pooch

Love the channel. You could have just skinned the old firewall and moved it back and the engineered bends forms in the old one add strength. Just adding a flat piece of plate does not make it stronger. Should have bent tabs on the ends and spot welded it in like the original.

I'm loving the new content. I'm not too keen on where this project is heading though. Keeping it as stock as possible would have been amazing.

Looking awesome. Personally I would hire a bead roller if you can and bead roll those firewall pieces, it will add a lot of strength to that firewall for any sideways sheering forces. Thats also the reason that the mounting points on the OEM one are recessed, to add strength where the accessories are mounted.

That firewall will resonate like mad

Good progress! Check your foot well for room for the pedals!

When steel is pressed it's becomes stronger. Your sheet metal is flat so the old ones better. The other guys have already said that too to be fair. Please redo the firewall correctly for your safety if you have a head on accident the engine will take your legs a lot easier

Here we go again!! Next your going to trying to build a new frame for it!!🤷‍♂️💯

The cross bracing is a good idea. Ford implemented the torque boxes on the frame in 1967-68 mustangs for this same reason. They were located a bit further down though. In 67 they only had them on the driver side. Nice work!

Should have waited on the firewall until you have the engine mounts.

So much for keeping it kinda stock. Should have put a good motor in it and keep that coyote motor for another build. The horse your gonna end up with the only thing your keeping is some body. Gotta box the frame. Swap rear-end, beef up mounting for it. Nothing that car had can handle the horse you'll be making. Soon as you put the power to the rear wheels, that frame gonna twist.

I admire your resilience especially after the last Mustang failure, but I see the same mistakes being made on this car. There is a huge difference in collision repair and building custom cars. The collision work you do is flawless, I just don't want to see this project end up like the last one.

Bro you’re basically building a car from scratch and that’s actually mind blowing 🤯

Those flat panels are likely to make popping sounds when you drive over bumps and make turns, etc. The factory makes indentations in the firewalls to prevent this and also to add strength. Same principle also applies to ductwork in buildings - the X bends in the panels adds strength and prevents them from making the popping noises. I believe that I would have just modified the stock firewall.

The Stang is coming along nicely, can't wait to see it when it's done. I just finished the 4 year restoration of my 1981 Chevy C10 and it turned out really nice.

Don't get too "custom" Ben. Remember the other Mustang and how that went with all the custom fabrication.

Great enthusiasm. Maybe a little more planning. Check out Astill Design and Phat XB channels to see the level of planning with some Aussie custom builders. Pretty sure your 4x2 box is where the tyres go.

Props to Vtuned. Doing all the work yourself is not easy!! The fatigue must be real, but he hangs in there.

Your production quality, sound, music and content get better and better. And your skills are still the maddest skills out there. Love the channel. Keep em coming!

down the rabbit hole again :-) stick to the plan....no wait... is there a plan? or make it up as you go?

Keep up with the good blues tunes 👍🏻. Lookin forward to seeing this finished

Very nice! Just a suggestion... Some sheet metal machinery would help out greatly. A bead roller as Yousef K suggested would help immensely. My Dad just sold his sheet metal equipment. A lot of the bead rollers were old, but they worked great and are more affordable than new stuff. Plus... if you own a metal lathe or have access to a machine shop, you can create new dies to fit your needs. A little box and pan break and a roller would meet all of you fabrication needs. Look for old stuff on equipment auctions and you can save some cash.

You are turning this into a death trap. The structural loadings between the front chassis rails and the rest of the tub are significant and complex, and you cant just make up a solution as you go along. Flat sheet is a poor substitute for OEM curves and indentations.

Killin' another classic...RIP

Thanks for sharing your build, I like it. Keep up the good work!

It will be plenty strong once you complete the trans tunnel, you do you . Love the vids and thanks for sharing the build .

Looks good. I would keep the old firewall so you can use the holes (like the steering column and brake booster mount) it has in it as a template for the new firewall.

vTuned killing the weekly build videos!

Great to see the creativity process at work while something is being built.

Hey Ben, really nice work with the custom firewall. With the cowl just cut some strips to extend it out a little and it will work nicely!

What about the inside of the 2x4 steel And the rust inside? You took the rust off the outside but inside still had rust

It might be easier to set the motor and transmission in the car than build the firewall

Great work! You're making good time on this one!

One small suggestion for planning ahead type thinking. Those 2 x 4 box pieces you put in first from frame to rocker could have been welded in at the same angle as the new toe board you bent up. Then it would have given the strength you wanted, provided another place to weld and support the new sheet metal and likely also provided a good place to weld in future roll cage front dash bars. Also would have recommended cutting the trans tunnel opening in the firewall before welding it into the car. It would have much easier to cut a nice semi-circle outside the car and on a flat table.

Can’t wait to see the stance with the Coyote bolted in 🔥

I am loving this build so much! Its what the other mustang should have been! Thanks VTuned!

Im stoked for this build looking forward

Go. You can tell the people that comment are not fabricates. That looks so much better than the stock bumpey and lumpy holey fire wall. Bring the cage down to the 2b4 and build it when you have the roof cut off. The music is better to. LOOKING GOOD.

Turning junk into a gem. Vtuned's signature talent. Thanks Vtuned.

i have a feeling that this build is not gonna go anywhere like the old one.

I love watching this build not just cause of the fact that it is a coyote swap. I love it cause I am always learning from the videos. I saw the thumbnail and wondered if you had a metal brake and found out you did it like all the rest of us was good stuff. Love it brother KEEP GETTING AFTER IT

My favorite build on all of the interwebs!

In all honesty building the firewall isn't a good idea without bead rolling it and boxing in body panels to the front sub won't help for strength in the back of the car. You need subframe connectors at minimum for anything more than 400 hp. I grew up with 65 mustangs and they twist like wet paper.

Loving the content bro. Keep grinding 😎

awesome work man, keep at it!

And if you tie your cage in at the front to those boxes you just added, you can triangulate back forward to the frame with some round tube for more rigidity on the opposite side of the boxes. And sooooooo glad to see another Mustang project! But that Fastback is one of the most beautiful cars ever designed by man. Let's see that build too!

Ever notice how he always just starts welding random pieces of tubing everywhere without really thinking about how it is going to effect future parts of the build. Such as where the suspension will go or mount, or where the steering rack you be, etc. my guess is half the stuff will be cut out before this build is over, if it ever gets that far. Don’t mean to be a downer, just trying to be realistic. I really hope it turns out good in the end and he proves me wrong. But I’ve been cringing a lot at these videos.

What's going to happen with that 3 inch rellocation ? Wouldn't it affect the position of the gear lever on the interior? I hope you got that already figured out. I would love to see this build completed successfully!

I enjoy watching people attempt to do something that they are clueless about... Case in point, the Mustang fastback lurking in the background... 🤣

Very impressive…your fab work turned out fantastic! Keep up the good work…take care and God bless…David.

The specs on this build are changing faster than I can keep track.

After the "custom" frame on the original Mustang I get nervous when he starts talking about custom.

v-tune this one would have been sweet with a mild 351 and kept stock, i thought the fastback was the brute

On today's vTuned let's see how many more mustangs we can rip apart

NO THE MOTOR ISNT GOING TO BE MOVED BACK. IT'S GOING TO SIT EXACTLY WHERE THE MOUNT IS LOCATED WHICH YOU ALREADY WELDED IN.

I was looking forward to seeing a classic rebuild with a modern engine. It appears he’s just going to make another race car complete with roll bars, no heater, no A/C. I may be alone but what a waste of a low rust classic.

Hi Ben, A trick to filling in minor gaps and small holes is to temporarily hold a block of copper behind the opening as backer while you are mig welding it.

While you're fabbing, make a dead pedal for the drivers floor pan. Stability while driving and comfort on longer road trips.

I can't for the life of me figure out how this channel is over 500k subs...this seat of the pants hack job shit is beyond ridiculous. Cutting and welding steel is one thing...properly and successfully building a custom car is another..

Keep "trimming" on this classic car. It's definitely going to end up like the other one. You are definitely learning what not to do but at the expense of an "all original" mustang. You are probably going to lose some classic car guys over this one.

"Thank you, baby!" That lady seems sweet on you, boy. "Flashbacks" lol. The trauma of Mustang I. The candid footage collecting the invoice was cool.

This series and the car started off terrific. I am starting to get that sinking feeling now though. It has gone way off-script, and things are being done without much thought to the next stages. I really hope that he listens this time, and stops to think things through before that special car is beyond redemption. That 'firewall' may be of a slightly thicker material, but I can assure you it is weaker than even the compromised original one was. Your will flex, buckle and vibrate like crazy, and will become a detriment to your safety. A thin piece of contoured and shaped material is stronger, way stronger than flat expanses of material you have got. It is basic physics. Come on Ben, please don't ruin this car. Remember what you said when you first got it, then compare it to what you are butchering together now. It is not too late (yet) to get back on track to end up with a good, safe car that you can be proud of. If things carry on as they are, I will be unsubscribing, as I cannot bear to watch what is basically desecration.

You should reinforce the firewall with a bead roller! Check this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tg4nN1wZ7YI.html

This series gives the average Joe a great feel for the time, skills, and effort required to do this right.

"I'm having flashbacks man" 😂😂💀 that part got me

What you've done so far has been great,towards the strength of the front.PLEASE lift the front and put the engine and trans in the frame, and under the firewall to see where you have to modify,before you do anymore.Mark the frame where the mounts go,and where the trans mounts are needed under it.Then you can weld the firewall and cut the tunnel.Please.BTW;you have pre-cut inner fenders on your previous car builds parts.

PLEASE NO!! Please get the proper repro metal. This is going to end up like the fastback. Please do it right.

I'm afraid this might end up like the last one after all that hacking.

I thought great Vtuned has seen the light, but now "Hello darkness my old friend".

LOVE THE BUILD🤓🇺🇸👍

So much for being stock, 😒 Why are you going to ruin this car with a roll cage, this WAS a beauty

Another one in half what happened to "i'm keeping it stock",,,?

Ford put a thing called a torque box at the front corners of the frame to connect to the side rails. They design it in a very specific way to keep it from tearing out and to help keep the wheels out of the cabin in the event of a crash. What he put in there has those Ford designers going Doh!!!

Am always tuned to vtune from kenya nairobi 🇰🇪🇰🇪

Ben Stop and start thinking dont just wing it then u gona burn this project to . do a plan first

Anybody else having a hard time watching this nonsense…

That's a good idea. The way you were doing the aprons and the engine bay. In the other car it was going to look really good and clean.

Your Welding and Knowledge of Fabrication is Awesome
