sine the rx-8 is a modded 13b could i use the 6speed tranny in a GSL-SE?

 

Yup

 

It's a rib case though... You'd have to follow similar steps as with the Turbo II swap IIRC.

 

that'd be ******* sweet

 

Price range and availability? If its a $1200+ tranny, I think I'd still get it.

 

interesting idea.
how much modifing will it take?

 

it was just a idea i had bc im getting a SE soon and i know of a wrecked 8 i think i can get the tranny out of at pikes 150 :-P

 

Most new trannies from the manufacturer cost on the order of $4-6k. Plus the six speed is not based on the rib case design, its a six speed so its obviously has some drastic internal differences. Plus I've heard of several people having problems with it.

Then there is the question, why do you need a six speed?

 

i was thinking about this as well... but to bolt it to a 12a, why the 6th gear ? hell i get bored when i hit five and want to shift more... other reasons 5th tops out to fast if you have alot of power, and id suppose youd need alot of power, i dont really know id love to have a 6 speed just for having one. but if theres problems with those trannys count me out on them. otherwise count me in.

does anyone know the gear ratios in an RX8 box?is 4th 1:1,as in RX7 boxes?

 

I have heard of tranny problems with the RX8, it's really weak I guess.

Anyway, heres the gear ratios for the RX-8 compared to the gear ratios for a second gen Turbo II.

RX-8 Gear Ratio's

1st--3.76:1
2nd--2.27:1
3rd--1.65:1
4th--1.19:1
5th--1.00:1
6th--0.84:1
Final drive--4.44:1

TII Gear Ratio's

1st--3.483
2nd--2.015
3rd--1.391
4th--1.000
5th--0.719
Final drive--4.100

 

The RX-8 tranny is not related to any Mazda unit. It's built by Aisin and is a version of the 6-speed used in the Miata.

Thanks for the ratios! Let's see... 1st gear unusably low, 2-3-4-5-6 okay but could be closer.

Hmm.

- Pete (2.5:1 low gear, 1:1 high gear, and nice spacing in between... it's all I ask)
