like it says up top i have a 86 n/a what do i need to use a TII trans

 

This has been asked thousands of times in turbo conversion threads so if you do a search you should find the answer.

 

you are gonna need to use the turbo flywheel, turbo clutch, turbo driveshaft, and the entire rear end/subframe/axles/hub assemblies. you need a turbo donor car basically. i just got through doing this to my 1986 base model rx-7--jeremie

 

or you can get a custom drive line. I used the TII driveline and re drilled the holes to fit the n/a pinion flange

 

whats the point of using the turbo transmission if you aren't gonna use the turbo limited slip rear end to? the non turbo motors don't make enough power even a little modified to give the n/a transmission a workout.

 

Some of the 86 to 88 n/a's had limited slip rear ends.Some of the GTU and GXL's had them. The 89 and 91 GTUs had one as well as a 4.3 rear gear ratio. One might keep the n/a rear in a GTUs to retain the 4.3 gears. As for cars without a Limited slip I would agree. Change everything rear end and all.

 

dak, whats the turbo rear end geared at?

 

As far as I know all the North American TII's had a 4.1. Mazdatrix,Racing Beat,and Rotary Performance sell a 4.3 for the TII which I think was only available in the Japanese only Infini model.

 

You can use a NA rear end also if you get the Mazdatrix Turbo to NA driveshaft.

 

why would you want to use the R type tranny in a non turbo??? The M type that non turbos come with; is lighter and is perfectly fine even if you have only halfway decent driving skills.

 

who was the question directed at?
