1984 5-letter / S5 "Selene"

This is my 3rd FB, all have been Series3. I've been dreaming and scheming on an S5 FB for many years now. This time around, it's going to be raw N/A rotary power.

After years of putting feelers out, emailing phony craigslist sellers, and almost giving up hope of getting back into an FB, I found the gem I had been seeking.

I sold that to CodeBlue many years ago - 2003? 2004?

Have a box of it at home - with cleaner prep and bulldog adhesion promoter :)

Will do that when i pull the interior to install Hushmat & stereo this weekend or next week (notice the lack of headunit) - pics to follow

Looks like one sick car, looking forward to the build.

I'd be interested in pics of the sound deadening install, I am considering the same thing on my car as it tends to sound like you're in an enclosed go-kart sometimes. It would be nice for sound quality and I wouldn't have to listen to the wind noise as much.

What started as a simple wire fix...
 
6 Attachment(s)
Needed to fix the plug for my trailing ignition - the other day I was playing around with wire tuck ideas and snapped the 30 year old wire in half :( no tach or trailing.

Then I noticed that my fan belt was TOAST. Literally falling apart and super loose. Thank's for holding out so long, baby! Sorry to push it like that. I promise I wont any more. Thankfully (thanks to ArmyOfOne) I had a spare belt lying around, so I pulled the fan to put that on. Well... I figure since the fan is off I might as well see how permanant the grime is....

https://www.rx7club.com/attachment.p...1&d=1360630297



Ah i see - it totally comes off. Well I can't just stop half way... so the rest has to come off.

https://www.rx7club.com/attachment.p...1&d=1360630297


And then Put it all back together. All this just to make a "quick trip" to the store to get ready for the interior re-do.

You got it! :icon_tup:

Interior re-do and Hushmat prep:

Ah yes. That smell. It's not THAT bad.... but then, it kinda is. Every once in a while you get a waft of it, and its like, "Is that me? No, no i'm fairly sure I showered sometime this week...." It is, in fact, the car. I mean, it's 30 years old so i'm not blaming it. But a lot can happen in 30 years. Smokers, water, spills, who knows. This car has definitely seen its share of all of it.

Time for a deep clean - get in there and clean up those hard-to-reach places.

Out come the seats.

https://www.rx7club.com/attachment.p...1&d=1360632015


Center console and carpets - out they go. And... what's this? Ah HAH! I see you, water logged, mildew festering carpet liner! Out you go! We have located one of our leaks. More than likely the floor plug directly beneath.

https://www.rx7club.com/attachment.p...1&d=1360632015


All carpet and liner removed.

https://www.rx7club.com/attachment.p...1&d=1360632015

https://www.rx7club.com/attachment.p...1&d=1360632015

A wire brush to get the bits of liner that got melted into the sound deadening. After that, deep clean. Time to scrub off the mold from the pools of water - ended up both driver and passenger side were soaked. No rust though! Lucky! must be a newer leak. Will have to seal that up.

Plus, I need to clean the surface in prep for the Hushmat anyways

https://www.rx7club.com/attachment.p...1&d=1360632015

A few small spots of surface rust. Wire wheel them down and hit them with some Rust Tough, and we should be ready to install some Hushmat!

https://www.rx7club.com/attachment.p...1&d=1360632032

And that took me up to 8:30pm on Sunday. Time to call it. Will finish the hatch scrubbing, leak sealing, and rust repair up next.

you know ... if i didn't know better, it would be easy to look at the condition of that car and think you really don't have to put much effort into "building" it. yes, it's THAT gorgeous!

Haha - wow, thanks man! It's got 183,000 miles on the chassis - and it shows here and there. Lots of little dings and dents. Faded interior panels, dirty dirty engine bay (cleaned half of it so far). All things considered it's an amazing ride - just needs the TLC of a rotorholic to bring it all the way to where I'd like it ;)

Alright. Past weekend update.

I have scrubbed every friggin square inch of this beast with a scrubber brush and simple green. Removed all rust spots save for one around the shifter. Cut out some speaker mounts, and began doing the Hushmat install.

And now what matters most, the pics:

https://www.rx7club.com/attachment.p...1&d=1361257980


I'm choosing to leave the holes open. I have had to put the window back in its track enough times to know not to seal that shit up. i will need to replace the windows this year anyways, so might as well not waste the mat

https://www.rx7club.com/attachment.p...1&d=1361257980


Speaker mounts - 3/4" MDF. BE SURE to wear eye protection and some sort of breather mask. You dont want to inhale shit when you're working. Especially MDF.

Weekend of Feb 23rd - stereo
 
5 Attachment(s)
Whew! So i told everyone I was dead so they would leave me alone for the weekend and locked myself in the garage. The interior has been completely pulled for about 2-3 weeks now and I'm getting antsy to go drive. So I gotta get shit done!


Last Friday I finally got all my seals, plugs, and cover plates in. Grind off any surface rust, use some silicone to seal them up, ready to be covered with some hushmat :)

https://www.rx7club.com/attachment.p...1&d=1361814563

Ground out some rust spots and spot painted with some Rust Tough (love that stuff)

https://www.rx7club.com/attachment.p...1&d=1361814563

o noes! this is almost the last of it. I found a cancer spot on the passenger rear wheel well :( will have to take it in and have it welded up. This looks like just a bad seal around the shifter hole.

https://www.rx7club.com/attachment.p...1&d=1361814563

https://www.rx7club.com/attachment.p...1&d=1361814563


Now she's all prepped and ready for the next phase! FINALLY. I enjoy taking my time and doing things right, but I couldn't stand seeing those speakers taunting me on the floor day in and day out. Something had to be done about it, and she's finally ready:

Rear speaker plate mounted

They suggested I use butcher paper to draw out templates. Honestly I found that to be a waste. I would cut the piece by eye / test fitting. This stuff is super handy.

A handy tip for installers: I discovered that if you start by sticking down the far corner, you can pull the backing off by pulling towards you, and as you pull it sucks the matting down to the floor while removing the liner. Its plasticized, so it (usually) wont tear.

You do this for each little bit or 'arm' of the matting, this method allows you to reach some really obscure places with the mat.

https://www.rx7club.com/attachment.p...1&d=1361815027

/\ That, leads to this \/

https://www.rx7club.com/attachment.p...1&d=1361815027

I went up inside the wall about 8-10", as far as i could reach my hand up. Tiny hole and wires / tubes to work around.

Front Speakers
 
5 Attachment(s)
Oh man. The front speakers. So this is my 3rd FB that I've done this on. I dont know why i keep coming back for more. These things are a royal pita. Seriously why do i insist on speakers larger than 2" in the front!?

Because they sound better and carry more mids. Thats why. And so here I go again. However, having done it several times already at least I knew what to look for.

I had to modify both speaker grilles, and the drivers side mounting plate as well. On the fronts I don't pre-mount the plate, its most efficient to get long screws that go through the speaker mounts, grille, mounting plate, and wall. I hate doing this, I hate drills anywhere near speakers. Don't ask me why. Ok I slipped and punctured a speaker once. And not just some shitty cheapo speaker, an MB Quart (old, better version) *hangs head*

PRE-DRILL. Don't ruin your speaker, MDF riser, or wall by trying to save time. You wont, you'll have to do it all over again and maybe buy a new speaker when the power drill slips and you punch through the speaker.

Passenger side front top corner is blocked by the heater. I usually pre-mount the speaker in this corner, then drill the other 3 bolts into the wall. I had to cut away the grille to get this to fit, the mount and speaker fit just fine:

https://www.rx7club.com/attachment.p...1&d=1361815516

Drape the speaker wire over the top of the speaker and line it up with the stock wire divot at the top of the speaker hole. we'll seal it up later with silicone at the final stage. The plate is made from MDF that i sprayed with semi-flat black Rust Tough. Have I mentioned yet I love that stuff? Dries enough to handle within 2 hours. MDF dries in 45min to an hour if put in front of a blower / heater.

https://www.rx7club.com/attachment.p...1&d=1361815516

The mount extends to the very limit of the stock kick panels. I mount it over the top of the door trim finish piece. Before permanantly screwing it on to the car I took some simple green and cleaned it real nice. Little scrubber brush from O'Reiley's for the win again!

https://www.rx7club.com/attachment.p...1&d=1361815516

Driver's side speaker you can access all 4 screws if you un-mount the fuse block and the little brown relay below the steer column. The hood release is in the way, so I had to cut out a bit of the speaker mount and grille frame. Didn't have to cut the grille like I did on the passenger side though.

https://www.rx7club.com/attachment.p...1&d=1361815516

All up in my grill, yo

Speaker chamber isolation
 
5 Attachment(s)
So a lot of folks who have door mounted speakers talk about how much more mids and mid-bass they get by totally sealing the door chamber. Makes sense, as if you want a ported speaker you need to engineer the port length and diameter based on the speaker requirements.

I had originally planned on blocking off the sidewall channel where the speaker mounts and creating either a sealed or ported "box", using the holes in the frame as a port. So i ran the numbers on the speakers to calculate box size, both sealed and ported.

Basically what I came up with:
Ported: for a ported box built into the sidewall, it would need to be rediculously small with a port length of 74". I dont want to route 6 feet of 2" tubing through the sidewalls. So, sealed box:

For a sealed box, I wanted to isolate the narrow frame channel where the speaker mounts into. No go - there is so little volume in there it is too small. Bascially, I realized the Mazda engineers already solved this problem. Hm. Go figure. Using the same ideologoy as the door-mounted speaker, I sealed up the sides of the walls to direct the sound better, isolate road noise to speaker noise, and create a a large sealed(ish) box for the speaker.

https://www.rx7club.com/attachment.p...1&d=1361816413

The only space left open is near the very rear of the car in the bottom corner, about this is about 2"x2" square. On the driver's side this is the hole behind the hole for the gas tube. On the passenger side its the hole where the antennae cable runs.

https://www.rx7club.com/attachment.p...1&d=1361816413

12 awg speaker wire run. Exhausting. Time for some refreshment

https://www.rx7club.com/attachment.p...1&d=1361816413

And finally! Sunday evening at 9:45pm, the fruition of all my weekend's efforts. Speaker cable run, speakers mounted, Hushmat installed

https://www.rx7club.com/attachment.p...1&d=1361816413

https://www.rx7club.com/attachment.p...1&d=1361816413

To finish things off I need to run the power cable, create an amp mount bracket (will go under passenger storage bin), and then tap into the factory head unit line-level output.

Oh and get that damned wheel well rust taken care of :(

DreamInRotary 02-25-13 03:06 PM

Thanks a lot! Just one more thing to add to the To Do list for the FB I guess, the list goes on and on.

You used Hushmat here I see, how would you rate your overall experience with the product? I've done some researching on the different mats available but not many 7 owners will be honest about the experience.

Also, it would be cool if you had a sound clip of road noise, then a clip of music playing both before and after the installation. I know in my 7 the road noise is terrible and I can't hear the music to save my life even though I've upgraded everything possible.

Anyways, nice job and keep the pics coming :biggrin:

I LOVE working with this stuff. Once I figured out the technique, i was flying! Well actually i take a long time to do anything, but it wasn't obnoxiously difficult. for the hard to reach places, i found cutting smaller chunks made it much easier. Also, the technique you use to determine where to cut each sheet can make a huge difference. I suggest looking at how they did the stock matting and going from there. Learning to do angles, corners, and curved surfaces took only one sheet before I figured it out.

Anyways, nice job and keep the pics coming :biggrin:

I know that before / after stuff is the best way to demo a thing, and I seriously thought about doing that for this project. A few things made me decide against it - a camera's mic can't really pick up all the nuances of road noise, the pressure you feel on your ear after an hour of driving, etc. If I had a field recorder I would have used that, but alas I do not currently have one.

Second, I didnt have any speakers or stereo in the car previously, so there's no before / after there.
