Rx8 diff swap?
 

I have a na miata so my oem 6" diff is as weak as a box of animal crackers so I had planned on dropping in an entire tll drivetrain but the availability around me for rx7 parts is limited. The rx8 diffs are looking very attractive with there 4.44 fd. Would it be possible to put an rx7 outer axle cv on a rx8 axle? I ask bc I already have some miata hubs machined for rx7 splines. Has anyone completed this other than the nc miata guys?

oh man.. periods.. are.. your friend....... ... ... ... ... ... .. ... ... .

Sorry I thought this was a miata forum....... I'll move it to the grammar forum........

It isn't that we expect perfect grammar, but if you are asking for help, the least you could is put some effort into making it easy for people to read. If you type questions that way, you will not get many, if any, educated useful responses. It makes it seem as though you don't care enough, so why should we?

If you don't have any answers to my question other than talking about my grammar then don't post.

If you don't have an answer to my question, then please don't post. I don't understand grammar or sentence structure.

You haven't been here long have you...

Probably wont stay long either...

I guess I know one member who doesn't have the answer for my initial question.

So use a 1.8 7" diff?

The 7" diff is an option. I would like to use the rx8 diff bc it's a 8" diff

How many 7" diffs have you broken?

I'm glad you feel entitled to answers from us.

I haven't torn up any diffs. I'll be doing some drag racing with the car and I'd much rather put a diff in that's beefy enough to handle anything. I've seen some destroyed 7" diffs and axles in other threads.

I don't feel entitled to answers. But this is a forum for asking questions and being talked down too about my grammar seems childish.

Not using understandable, legible grammar is what's childish.

The diffs aren't really what's known for breaking in these, it's most often the axles as you mentioned.

Anyhow, I'm done ball busting.

Just remember: If people are blowing up diffs and axles and you hyper-beef up those parts, then something else (probably more expensive) will break instead. Many like Bryan who have broken axles choose to keep replacing broken axles when they go because they'd rather break axles than transmissions, engines, or whatever else.

Very true beefing up one part will cause something else to break. I've got a turbo ll trans I'm installing also. I'd like to have a solid drive train to keep from replacing parts. The engine will be the weak link.

I agree my grammar isn't very good and will probably never be. I'm a welder by trade so it's not really on the top of my to do list.

Your grammar is fine now.

Tis cheaper to replace axles than engines. Just a thought.

Thanks for the input

You seem to of pryed your answer out of one of our nicer members, but please remember we have a warning for poor grammar for a reason. The site as a whole enjoys answering easy to read posts.

And is being a welder really your excuse for forgetting your language education? You wrote better the more we teased you about it, all we ask is a little effort be put into each post.

How much power are you making?

That's easy. Allofthetorques, because 12A rotary.
