turbo miata cts rear end
 

Hey guys ive been doing research on the rack and pinion swaps 3.6 being the best gearing but i kno this can get pricey wouldn't it be better just to swap in the fm rear in kit and get a custom driveshaft to mate it to the 6speed ,being more durable

Damn. 3.6:1 ratio steering rack? Sick.

The rear diff dude

I don't have a rack in my diff. Do i need one?

Wow

Play stupid games, win stupid prizes.

Yeah your prize is a cookie when would you like me to ship it?

Sorry, i'm trying this gluten-free thing, and i doubt you have that sort of cookie on hand.

I'll tell you what, though. I'll throw you a bone. :)


So what you want to do here is... spend a couple grand for a CTS-V rear end, and then attach it to the same weakest link in your driveline you had to start with.


Sound about right?

Aww sorry to hear your on a diet ,i guess you dont get a prize better luck next time

Not a cts-v rear end im look at the base cts there pretty cheap ,im getting rid of my 5speed for a 6speed reason being im building a high boosted miata im trying to see if anyone has done it

Dude.

In for awesome new eggplant pictures.

... did you happen to search "CTS diff swap miata" before making this thread?

Let me google that for you

Sorry im at work im not typing things right im try to find out has someone did the cts rear end on the 1.8 motor

Dude.

Let's call it what it really is - the V8Roadsters diff kit. And you can get it from V8R with a driveshaft, no need for custom.

/useful info

carry on

yeah i have i only found the cts with the v8 swap,im trying to see if anyone has done it on a 1.8

Are you thinking that installing your rear end will be drastically different depending on your motor of choice?

To mate it with miata tranny?

No just want something that will be durable and take abuse

Then what's the question?

Huh, cool, they have an adapter so you can bolt the CTS diff to the PPF now.

But yeah, costs twice as much as a 3.6:1 R&P. Potentially useful if you're still pining for the unobtanium 3.3:1 ratio, though.

Is the kit $1500 without the diff, or do they include one at that price? I'm thinking no, so it's a lot of money.

For our retarded friend, who can't read so good.

"We utilize the Getrag in our road course and street cars. When sourcing the Getrag look for the 2006-2008. The later models have casting and seal updates. G80 series limited slip GM part numbers: 3:23 - 25978162 3:42 - 25873500 3:73 - 25873497 3:90 - 25968531 . We offer new differentials for sale. Check our GM parts section.





This kit is for stock Miata transmission and PPF. Kits for LSx and LFX conversions can be found here "

The Getrags are $250-300 from junkyards, not a significant cost relative to the rest of the kit.

PPF and Diff (depending on year) need heavy clearancing to fit. Basic mechanic skills needed for the install.

Tranny is still the weak link, not the diff.

OP. Check out this link. It's been done and documented here already.
