Lookin' good. I can always appreciate the "bastardized" builds.

What diff is in that rear end right now?

Bastardized? I know the parts are mixed/matched but come on, lol. I think the end result of the turbo build came out pretty clean, IMO

I swapped out my 1.6 diff for a 2001 NB rear end. I was bitching about the one piece axles but in the end I love the clearance I have for my 3". I ended up making my own exhaust hangers and I was able to tuck the piping up a bit closer to the car for that little bit of extra clearance.

Florida roads are notorious, lol. I had a friend in his s13 coupe crush his muffler going over a manhole! Apparently the city decided to dig up parts of the road to recover the tops and leave the manholes the original street height, lol.

Trust me, Bastardized was meant in a loving term.

I meant you've got a torsen now right? Leave it. Don't put a RX7 diff in.

Bastardized = <3. I dig it. I'll post some pics of the turbo E30's I work on.

Open diff. I will in no way, shape or form pay for a torsen. I will grenade it at the strip or on the street. I'm done using my car as a track rat. I'm rebuilding everything to be a nice street car that will run mid/low 11's. I may go to a autocross every once in a while, but not enough to warrant a torsen. The RX7 clutch diff should be perfect for my needs and will not break the bank.

By mid summer, this car will be at around 350whp (thanks to my secret weapon).

Okay! Decided to do some small projects today and ended up a **** fest.

Reinstalled bumper core support:


While I was down I decided to cut some old silicone and use them in strategic places to stop the a/c lines from wearing a hole in my silicone cold piping:





That all went smoothly. Then I thought I would bleed my brakes and get rid of the chocolate milk in my reservoir. Starting on the back first, I noticed that my diff mounts looked "off" as in they didn't look right.

I'm still not sure how it slipped by me Using my new found experience in everything differential, I lowered the diff down. Inspected the mounts.etc. It just wasn't sliding up the bolts enough. I was able to get maybe 2-3 threads with the nut and that with the tabs OFF

So I lowered it back down, greased the hell out of it and was only able to get a little more out of it. I looked at pictures on line and it is easy to see the considerable number of threads available on the subframe bolts.

This worried me, so I kept at it. I must have benched that ******* diff 100 times today. I feel like I hit the gym for three hours. After a few hours of just ******* with it I made progress. Pics:

Pictures of the diff mounts on both sides:




This how far I can get it up the bolts:


You can see that is touching the subframe but the problem is that I am getting enough bolt to thread the nut onto.

I can *almost* get the nut on with the tabs now. I am close but no cigar, yet.

If some one wants to chime in and give advice, lol or call me a douche feel free.

Problem found but not solved. Solved will be tomorrow.

Turns out its the metal piece that extends downward from the diff mount. It's too long and is not letting the teeth on the tab touch it at all.

I am dropping the entire diff tonight and taking to a friends house were he will use a cutting wheel and level the bottom of the mount flat. That should give me plenty of thread to mount everything back up right.

My double jack, diff mount


You can see how far the metal inserts of the mount stick down, they are covering all my thread. Just FYI, the diff IS mounted high enough. You can see from my previous pics, I benched the damn thing and slammed it into the subframe, it can't go any higher.




The metal part sticking down is hitting the middle of the tab and not letting the teeth touch the diff.


I'll update tomorrow on how smoothly the cutting goes or if any one has any other bright ideas PLEASE LET ME KNOW.

I am glad to have started the trend of "write intro thread after 1000+ posts". The blue miata is very nice.

I'm sorry, I don't have anything valuable to add about your diff issue. I've never done that kind of work before. All I have to say is that if you make it fit, then it fits. Sawzalls are helpful for that kind of work.

I did my intro thread 2 years ago, lol this is just a history lesson and build thread. My first two years of college I was a English major, blah blah

It's cool, I don't have any knowledge about this either. I Just hope it works. I did the measurements and it looks like it should come about perfect with the amount of threads exposed on the subframe mount bolts.

What's different about your diff or car that's causing this to be a problem that nobody else has had to deal with?

viperormiata

iTrader: (24)

I have no F'n idea.

The differential is sliding up the subframe mounting bolts just fine, it hits the subframe and doesn't leave me enough threads to bolt the mounting tabs on.

That was issue number one, then I realized (as you can see from the above pictures) that the mounting tab teeth are not touching the diff. The mounting tabs are coming in contact with the metal tube that runs through differential mount, the metal tube is too long.

Alright, well that didn't go as planned. Spent most of they day trying to get a first start out of my friend's turbo E30 and then when we got back to my place, the cutter was too tall and not powerful enough. We started to run out of light.

I think the best solution is just get some MMR diff mounts. I'll need them anyway, might as well get them now when I have the diff out.

If any one has some sort of clue why I am the only person in history to have this ordeal, please let me know.

JayL

Get us some measurements so we can see which part isn't right. Start with the length of the metal tube in the diff mount, it should measure right at 2.5".

viperormiata

iTrader: (24)

Jay, I did....It's nearly 3.5 inches.


I have a set of MMR diff mounts on the way here.

JayL

iTrader: (12)

Problem solved, now the big question is how did the old mounts grow an inch?

Is that the aluminum carrier off the RX7 Rear? You need miata mounts for it dude. Else the rod sticking out is 1" too long and you can't bolt it up.


I can't tell from the pics, but it appears to be.


EDIT:




okay yeah, that looks like an rx7 carrier.



miata carrier vs. rx7:



and there is no break away notch on the right "wing", correct? I see it on the miata one in your picture.

viperormiata

iTrader: (24)

Brain, I bought the diff, axles, prop shaft, etc..as a 1.8 miata swap from a respected moderator on here. I have absolutely no idea why in the hell it would be a RX7 carrier.

I know a few people on here use RX7 carriers, so hopefully I won't be troubled by this **** up.

I have a set of MMR diff mounts on the way, they should cure this problem for me. If not, what should I do????

viperormiata

iTrader: (24)

I think Brain has it right. I really hope this doesn't set me back a few more weeks, I am already pissy enough as it is having my finally running well car off the road for two weeks. I don't want to be "that guy" and write a angry letter to said moderator.

Fleshlight is not a ***** pump but good try.

moderator narrows it down quite a bit. im assuming Phil?


just install the diff mounts and be done with it.
