I know that the australian RX8's had to be de-tuned to 170kw from 06 onwards I think it was,due to the emissions laws here.So the RX8's from the last few years have 170kw while the first ones had 177kw.So if the new RX8 is identical to the current RX8 mechanically(with the exception of the diff ratio),then won't it have 170kw like the current RX8's do here??

All they did was change the way they measured the rated HP

Cromax

That is what the articles say from what I've read.

Cromax

No ... your'e talking about something different.

DrGonzo

Assuming the outputs are the same, with the shorter ratios will that mean that the torque will increase?

Also, I read somewhere that the auto picks up a bit of power thanks to a new transmission.

Cromax

Yeah, but it probably picks up a lot better because I recall reading that it was running the same setup as the manual now (bar the fact the transmission is differnent).

auzoom

The point of the final drive ratio change was to increase acceleration. This will show an improvement in torque at the wheels but the engine itself hasnt changed.

dannobre, for real? I was of the belief it was an ECU/tunning affect.

matt13b

I wonder how hard or expensive it would be to change the diff ratios on our rx8
's to the new RX8 ratio??

takahashi

I rather go for aftermarket ones. The final drive is in the diff. I will at some stage change final drive an LSD together

matt13b

I just had a look at the Knightsports catalogue and they sell a kit to change the ratio to 4.777?? Maybe I will look into that..

auzoom

There are a few around that offer them. If you are interested in the KS one, speak to Jason at REVS...fdracer here.

matt13b

I will.Thanks for that.I just got the brochure from Jason today,that's where I saw the kit.Lots of good stuff in there!

Cromax

You're thinking of going with a 9" diff?

takahashi

Any 2 way diff is good enough for me

auzoom

Nate, he is thinking of a 4.777 ratio diff

Cromax

Oh, ok ... why?!

auzoom

same reason Mazda is doing it for the SII.

takahashi

I found a 5.222 something final drive too... but I prob go for 4.777 ... well time to save up.

auzoom

with 5.222 you wouldnt need 1st gear would you!

Lennart

Honda S 2000 have 4,777. You can use this in Rx-8.
Where did you find 5,222. I`e a racecar and should like to have that one. The car is not streetlegal and I`e DNA- kompressorkit inthe car.

I remember you well... LP

5.125. It is limited offer. So I don't think a set will get out of Japan.

I will still want Nakamura san's product...

Lennart

Thank`s for your answere. I`ll try to get one thrue my contact in Japan. If it works out I`ll post a reply here.

Lennart

Thrue my friends in Japan I`ll have one in Sweden end of Februari.

Lennart

My Final Gear has arrived. Will install it next week.
