NA Diff

Hi all

I have an NA6 with standard diff. I am looking at upgrading to the NA8 diff.

I know what bits are required, my only question is, will my current LSD centre in the NA6 diff fit in the NA8 diff?

Cheers
Jaron

\"No\"

The NA8 diff center in a little smaller than the NA8/NB8

Hmm

Can anyone recommend a good lsd centre?

Maybe I will stay with my NA6 diff a bit longer. I will miss the LSD....

well, you could always try to sell the NA6 LSD & diff. To recoups some of the cost. I'm sure there would be plenty of takers.

A full conversion would be around $1500-$2000 depending on where & how you get your bits together. Minus whatever you get for your bits.....

If you can wait a few months I will be selling a 1.8 conversion with clutch type LSD fitted...it's a Kaas or Cusco something like that...not sure which one yet as it's still in the car...

Probably will be asking a bit under $2k for it.

When you do the upgrade, if at all possible I would try and stay with the 4.3:1 ratio so the car doesn't lose acceleration, or it may take some of the fun out of the car.

jcs86,

You can buy my disassembled Mazspeed LSD for $400 which will drop straight in to your car and keep the 4.31 ratio.

Or you can buy a 1.8 rear end with LSD and refit a Mazda Bravo or Ford Courier 4x4 front diff which is 4.4, figure 2K for the 1.8 bits $300 for the new ring and pinion and $500 to fit and install 4x4 ring and pinion. Do it all at the same time and you'll be up for around $2800 Do it one at a time and your up for 1K more.

Been there done that :shock:

I was planning on getting a 1.8l rear end keeping the 4.3 ratio and putting a decent lsd centre in and then selling all the 1.6l bits

I've got an 1800 diff/tailshaft/driveshafts with a TorSen II and 4.3:1 ring gear, it's brilliant, couldn't be happier. Give Richard at MX-5 Plus a call and he should be able to get you sorted.

my prices were:
1.8 open diff and shafts (installed by Dodgy Sab and Dodgy Andrew) - $500
Baba's Torsen - $600
wrecker 4.44 diff - $250
so $1350 in parts.

cost of never getting around to installing the diff:

Worthless. (Still, I sold the torsen and 4.44 at cost)
