Time to start looking at wheels. Suggestions would be useful, but don't be surprised if I think your wheel choice is dumb.

Size is going to be limited to 15" in either 7 or 8" width. (won't be certain until the rear axle is in. PCD is 5x114.3.

Ideally, I would like some Enkei 92's, but we'll see about funds for those. Kind of need to be cheap right now.

I would also like something else old school looking, like Rota Shakotan, but I can't find anyone who sells them in the PCD I need. I don't need to hear Rota hate, I'm not a baller and this isn't a racecar.

Love meshies.... Timeless look and would compliment the old skool well.

FerociousP 02-26-2014 12:27 PM

Stock vert wheels with 205s or 215s. Cheap wheels, cheap tires, look good, Mazda centers, yes they are 6.5" but you have no need for more tire at this time, can easily borrow Curby's for test fit. Doesn't get cheaper or better than that.

85rx-7gsl-se 02-26-2014 12:38 PM

I would consider looking into some old school domestic wheels as a vintage mustang pattern would work. Just my worthless 2 cents.

85rx-7gsl-se 02-26-2014 01:10 PM

Mayba something like these:

True, but you get the general idea. Besides, this isnt a race car lol :)

Indeed. However, to make a slower car faster (quicker), lower the weight. Considering that the unsprung weight of the wheels is the greatest to overcome, I would rather have lighter than heavier!!!

djmtsu 03-12-2014 09:43 AM

More stuff happening. Pretty much all taken apart, waiting on parts!

https://lh4.googleusercontent.com/-p...4582818275.jpg

What is this malarkey?

https://lh3.googleusercontent.com/-Z.../IMG956426.jpg

Looking pretty.

https://lh5.googleusercontent.com/-O...19487058_n.jpg

Here is what is left, and what is happening with the beast.

The GSL-SE stuff is going to have to wait until summer/fall to be fabbed/installed. The front struts and rear axle need to be completely rebuilt, and I don't have the funds for that right now. Since I already rebuilt the Cosmo rear end last fall, I figured fuck it, I'll just run the Cosmo stuff.

Fun fact, the Cosmo rotors are bigger than the GSL-SE stuff....

The front is all apart, waiting on ball joints, sway links, and brake pads to show up. Trans is out and getting resealed. New Exedy clutch is here.

One issue that I found yesterday....the horror of fuel that sat in a tank for 15 years....

so was it pulled, disassembled, cleaned, painted, and put it back together with the original hard seals? why all that work if the engine was good?

not hating, just curious. edit: i'm awaiting an update here with this thing running.

FerociousP 03-13-2014 04:07 PM

Those housings did look great. I wonder how much the PO paid for them when the engine was first rebuilt...

djmtsu 03-13-2014 04:10 PM

Two reasons why it was pulled.

1). It sat for 15 years (with periodic oil squirt and turns) so even though it had relatively few miles on it, I was concerned the oil control rings would be toast, and they were.

2) Charles and Adler are good men. I'll leave it at that.

djmtsu 03-13-2014 04:12 PM

I used to have the receipt.

$837 for the rebuild in 1988 money.

EDIT: Online inflation calculator says it would cost $1655.01 in 2014 money.

Wow for 15 years of sitting thats pretty good.

jacobcartmill 03-13-2014 04:29 PM

DJ, i will go to deal's gap if you get this thing running.

djmtsu 03-13-2014 04:29 PM

Yeah, I don't know how often the PO turned it (he said every 6 months), but I turned it every month using a squirt of MMO. Also, when Neal had it for that year and a half, I don't know if it was ever turned over. But yes, when I got the text from Charles, stating that the irons/housings were perfect, and the apex seals were in 'new' spec, I was quite happy.

So far, I am waiting on a couple things to be ready to go. I need to buy some fuel hose, my strut inserts haven't arrived yet (3/18), and my wheels won't be here for a couple more weeks. Also, this weekend I am cleaning the tank.

Waiting to be installed:

Front brake pads
Strut tops
Clutch slave/master
Brake master
Ball joints
Front and rear trans seals

Once the engine gets back here:

T-stat
Motor Mounts
New hoses (coolant/fuel)
S4 Alternator (ahem Robert)
Accel (I think) coils
Exedy Clutch

Then, its a matter of installing the radiator/oil cooler and hope for the best. I should order a fuel pump, but it looks new. I'm more concerned at this point in time with it running, rather than how it looks. Still need to 'tuck' the bumpers, and pick up a muffler (maybe).

I will probably have to do a driveway break in before DGRR. Lol.

jacobcartmill 03-14-2014 12:48 PM

ok DJ, my challenge still stands. you get this running by deal's gap and i'll go as well.

do you accept the cartmill challenge?????

djmtsu 03-14-2014 01:33 PM

The challenge to get it to DGRR was set by myself, and motivated by friends who want to see the car, and are not local. That is the reward.

You are assuming I care whether you go or not.

jacobcartmill 03-14-2014 10:24 PM

a valiant and noble response, sir.

and yes, i am assuming you care.

Sorry man......that's the first thing that came to mind lol.

djmtsu 03-15-2014 08:58 AM

Worked on a few things yesterday, mostly involving cleaning the fuel system.

The tank had about 5-6 gallons of fuel in it......from 1999......

Filler neck, gas cap, and inside of the tank were all very crusty looking. So, I had some Evapo-Rust I had been playing with for a while for smaller parts, and it worked well.

Soaked the filler neck, cap and fuel level sender in it overnight. All came out minty clean and looking brand new. This stuff works awesome. It is expensive though, put I went ahead and ordered a 5 gallon bucket for the tank. All sealed up, I dumped 5 gallons into it, and have started the process of soaking/rotating/soaking/rotating. Sunday I will dump out the Evapo-Rust through a strainer, and then dump it back in and repeat the process.

Seriously, this stuff works. Adler and Charles were amazed when they saw the results of the filler neck.

Some other bonuses of it:
-no odor
-biodegradable
-non-toxic
-reusable (as it gets older, it just takes longer).

Other things done:
-new motor mounts installed
-new trans seals installed
-new clutch installed

FerociousP 03-15-2014 09:05 AM

pics!

djmtsu 03-17-2014 02:11 PM

The Cosmo lower ball joints are threaded in, not pressed. The SST for the job is NLA (of course). I've been trying to use a pipe wrench to crack them loose, but nearly pulled the car off the jackstands!!!!

This should be fun.

Oh, also ordered a new fuel pump, and all rubber brake hoses.

Heat is your friend.

djmtsu 03-18-2014 04:38 PM

Heat hasn't helped.

These mother fucking ball joints.......

I guess I'm going to have to put the car back on the ground so I can get some leverage on them. With 4 corners on stands, I nearly had a major incident.......

FerociousP 03-18-2014 08:53 PM

Your not cursing enough ...

jacobcartmill 03-26-2014 12:34 PM

in for updates.

djmtsu 03-27-2014 07:15 AM

Updates are as follows-

All parts needed have arrived, with the exception of the wheels, which should be here next week.

The front brake hoses I was sent are wrong. They are fine pitch, not coarse. The ones on the car still look good, but I'm trying to figure something out.

The rear end is back in it and ready to go.

The front struts require a special tool to take out the cartridges. Luckily, the service manager at my work used to be a machinist, so he is making me a tool.

The engine bay is in primer (mostly).

Trans is ready to go back in.

I took the oil cooler hoses to Patco to have them tested. They are good to go, so I don't need to have some made.

Since starting my new job, I haven't had a ton of time to work on it. But its getting there. Might not look pretty for DGRR, so it'll have that 'barn find' look, but be mechanically rebuilt.

85rx-7gsl-se 03-27-2014 07:47 AM

Can't believe you have had this for over 2 years.

Do SA front brake hoses work? I know they are the right thread pitch. I have some new ones laying about I can part with. IM me if you want em.

FerociousP 03-27-2014 09:36 AM

Good updates. Can't wait to see this thing driving.

You and I both. Been working a lot lately, and the brake hose issue threw me a little off. Still waiting on that strut tool to be made!

Once the struts are done, here is the list to do in order:

Reinstall front struts
Install new front brake hoses and pads
Install new sway bar links
Install fuel tank
Install new fuel pump
Install new clutch slave and master cylinder
Install transmission
Install engine
Install radiator/oil cooler
Install new rad hoses and stuff
Bleed all the brake and clutch hydros
Fill differential with fluid
Fill transmission with fluid
Fill engine with oil
Fill engine/rad with coolant
Reinstall headlights, taillights, associated trim
Find and install a muffler (this one is roached)

Really, nothing there is hard, or time consuming. The 'hardest' part is probably all the trim installation.

The first week on April (6th-12th), with wife and kid will be out of town. I still have to work, but I will have more time to work on it. Also, Sundays are free, so I can get stuff done then as well.

If any of my local peeps want to help, feel free to text me.

85rx-7gsl-se 03-28-2014 08:51 AM

I would lend a hand if I were closer.

Next two weekends are completely full for me, and i'm not exactly local anymore with a 30-40min drive each way, but if it really comes down to the wire i'll come down to help later in April. :patriot:
