ok so I have spent 2 day trying to find out about the drive shaft u joints and suck for my 87 RX7. now what is the difference in a drive shafts from a automatic to a manual? Is there a company out that makes aftermarket drive shaft for my FC?

Now I know I am new to the rotary scene, but I know I want to eventually go with a 13bt. I know I will need a engine, ECU, wiring harness, and a trans. is there anything else that I will need?

Where are some good places to get upgrades for my FC? I am referring to poly bushings, internals, exhaust, suspension? I am also looking for so deep dish rims as well, something like a 17x9 or r so. I have a lot of plans for this car but as we all know its not a Honda so finding parts fr this car isn't that easy.

Thanks for any help that you can offer and greatly appreciate the advice but the one thing I will ask is if all you plan to do is to tell me to search then don't post because I have been searching heavily but I am not finding all the correct info that I am needing or there isn't a strait answer.

 

Turbo swap information is all over this forum. It is the single most covered topic in the 2nd gen section. You'll find detailed writeups in the 2nd gen FAQ: https://www.rx7club.com/showthread.p...55#post5131155, which is sticked in this section as well.

Mazdatrix sells custom driveshafts for use in swap situations: http://www.mazdatrix.com/g9.htm. An automatic driveshaft uses a TII-style yoke with an NA pinion flange, but it is also shorter than manual driveshafts. It should never be used to mate a TII transmission to an NA rear end.

I would suggest advanced searching by thread title in the various sections. You'll find much more related to your search terms.

 

ok now another question is that i have read that if I plan on swaping out to the Tll engine that the NT transmission will hold but not as good as the turbo trans. now since I have to swap the trans anyways will it hurt to go ahead and get a turbo trans now? and would there be any issues with the clutch and such to work with the NT motor?

 

also what about the driveshaft? will I need to change it out as well as the rear end for this swap?

 

NA transmissions suck. You can get away with putting more power through them for awhile, but they'll eventually die. The synchros are weak anyhow.

Using a TII transmission on an NA engine requires a TII flywheel, TII clutch disk/p-plate, TII slave cylinder, TII starter and a custom driveshaft like Mazdatrix sells (manual shaft w/ TII yoke & NA pinion flange).

An NA rear end is considerably stronger than an NA transmission, so it does not have to be changed out in many cases. It just depends on power level. But if your rear end is an open diff, I'd suggest using an NA LSD in its place.

 

now is mazdatrix the only company who carries parts for the RX7 or are there other companies who arent so expensive?

 

If you buy NEW then you will pay dearly.
