5-Speed swap completed
well what can i say.................. it's done my 1990 Mazda Rx-7 N/A Auto is now officaly a 5-Speed. :cool: :D . And after all the money(about $800), bitching, cursing, and beating on things, all i can say is it was worth it all. i fell in love with my vert all over agian...... the car flies now burns out like crazy (can't wait to race my friends civic)
and i also wanna give a thanks to everyone who helped me with this: 'Vert in Vegas, knight1976 (both for all the parts), IceMark, hypntyz7 (both for advise, tips ) and whoever else that helped...... i still need a couple of parts, but i am driving it now(90 miles today already:D ) but i also now have so Q's: my cruise control dosen't work anymore anyone know y ?? i know its not a must but it would be nice concider how far i drive a day. Also s4 shifter (not the knob, the shifter itself) will it work on my s5? (i did seach but was left a little confused about it and now i can't find it to reread) i also need a shift boot where can i get one cheap (low on cash still from the swap) -Shawn |
you can use the shifter and look on ebay for the shifter boot they are always on there for the low low :)
|
congrats. I am attempting to do the same thing. How hard was it?
|
not as hard as some people think, i had alot of help from here, and my friends (free labor all it cost me was to bring them ride in it after) the cross member is a sinch. the only realy hard part for me was getting the pedals back in the car.
oh and time comsuming it took me 3 weeks to do but i was was doing it at school (could only work on it when i had free time) and waiting for parts , u do not need the pedal assembly , unless u dont want to modifi your current pedal assembly, all u need is the clutch pedal and parts that go to it (spring and shit) and a ride to home depo...... (if u wanna know how i did this i will gladly write it up for you r anyone else) like i said real easy (especily if u have a lift and all the tools in the world to use) anything else u wanna know? -Shawn |
Congrats man im glad that ride is now a 5 speed and rolling again. :)
|
yeah, i been meaning to e-mail u but i been real busy, my friend gave me a shifter knob so now all i need is the boot, how much wanna charge me for the cluster? (might as well get it while i can)
-Shawn |
also anyone know whats up with the cruise control????? i kinda miss it .............
on a positive side my volts jumped up a notch after the swap and my radio dosen't cut out anymore :) -Shawn |
Well i believe you got a credit line with me so pm me and we can work out a fair price :)
|
Congrats man! Cant wait to get mine back and be 5 speed :)

The '86-88 and '89-91 shift levers are interchangeable. However, the shaft of the lever that the knob threads on to are different sizes - the '86-88 levers are 12mm, and the '89-91 levers are 10mm.
As far as cruise control, check the easy stuff. Make sure the vacuum line to the cruise control unit is hooked up, and make sure the cruise control cable is hooked up to the throttle body. Also, make sure the "main" light on the cruise control switch lights up when you turn it on. Dale |
well it lights up, cable is hooked, i'll check the vacum line to see if it is hooked up tomorrow at school. i also have a lumpy idle everynow and then but it eventually goes away and comes back on its own
also to swap diffs. all i need is the diff it self? r do i need the half shafts to? -Shawn |
Originally posted by rx_7_driver [B also to swap diffs. all i need is the diff it self? r do i need the half shafts to? [/B] Stick with the NA diff, they're cheaper and much easier to find. Try to find an LSD diff from a 86-88 GXL's or the 88 GTU. |
well i found one from a 90 gtu do they have lsd?
-shawn (i only know shit about my car ) |
I did the same change over and my cruise control does not work and the fog lights to. i have not took the time to work it out yet but if you come up with something let me know thanks

It's quite possible that he doesn't have the neutral switch hooked up properly and the car thinks it's in neutral all the time, thus why the cruise won't kick in....
|
I've got a S4 diff assembly I'll give you for the 3.90 one you've got. God only knows what it'll cost us to swap them. (in shipping)
Anyone know if the diff carriers are different between the 3.90 and the 4.10's? I have an LSD out of a GXL that I'd like to keep but put the taller gears in so I can swap in a close ratio 6 speed. |

oh.... btw i decided to hold off on the diffy swap till summer when i will have more time to work on the car cause then i will be outta school
-Shawn |
congrats man. i love my 5 spd. i hate drivin my moms auto when the 7 is broken down!!
|
Since you have access to a hoist the diff swap will take about 2 hours. I'd like to get rid of my extra diff because if you need one I'd like those gears. I'm in no hurry to get them, but would like to have them lined up for when the time comes. I'm not even really sure if 3.90's are gonna be tall enough. (haven't done the math yet)
I'll send you the diff for the cost of shipping plus $20 for packaging. (it'll need a crate) It's yours complete if you want it. Or anyone else for that matter. |
Well, I'm not quite sure how it'd work, but I imagine it's because it thinks it's in in neutral/park and not in a gear that's causing it not to work properly, check the FSM for both the auto and manual and see what connections there are on the trannies, if the automatic has a neutral switch then just hook it into that.
|
I beleive the cruise control also hooks into the clutch switch that is on the pedal. Make sure thats connected :D
