RX8 ring and pinion
 
So I read on this website that the 4.44 ring and pinion from an rx8 fits the 94-97 miata. So I bought one and the ring gear is too big. Wrong gear from seller or wrong info?? Anybody try this? Please help a newb out...TIA

I think I remember that thread, and I'm pretty sure several people said it wouldn't fit in a NA/NB, but only possibly in a NC.

thanks for the reply.

I've also read many many things saying it won't fit. It should fit the NC as Dustin said though.

I have a 4.44:1 gear. I got it from Mazda Motorsports a few years back. From a Kia maybe?

Oh no. I am very happy with the set up.

pitbull113 12-24-2009 07:39 PM

Had to try. thanks for all the responses. so it goes without saying do NOT believe everything you read on the internet.

MMS also sold a 4.8 r&p.

pitbull113 12-24-2009 08:20 PM

yes they still carry the 4.8 @ $279 and the 4.44 @ $479. figures I need the more expensive gear.

Corky Bell 12-24-2009 08:35 PM

Considering all the torque of the turbos, that first gear is not of much use, and the fast cruise mode (west Texas), what final drive ratios do you guys feel would offer the best combo of fun?

I guess it depends on what you are doing. I am a drag racer using slicks, and I never drive the car very far. I love the combo, but would hate it if I did more long haul driving.

Joe Perez 12-24-2009 10:43 PM

~ 3.3:1. That'll give you 70 MPH at somewhat under 3,000 RPM on a 5 speed, and probably make first gear useful again.

I've got a set of 3.636 on the shelf, and have decided I'll probably be installing it in my car next month, as I'll be doing a lot of freeway commuting. We'll see how that works out. Should put 70MPH right about at 3,100 RPM.

What Joe said... and for under $300 a set. Market is right for this...

dustinb 12-24-2009 10:57 PM

What would the ideal gear ratio be for drag racing? And where would I get it from?

The ideal gear for all drag racing is 4.1:1, regardless of tire size, transmission gearing, engine powerband, etc.

As it happens I have a set in my garage in the 1.8-style fitment. I'll sell 'em to you for $500.

Six speed + 225/45/15...

Probably 3.0 to 3.3. This is a bit backwards compared to the rest of the thread though. :P

NA/NB ring and pinion will interchange into NC, and I assume RX8 as well.

Assumtion is the mother of all fuck ups.

The NC and Kia R&Ps are known fitments.
