Just did a 4 speed to 5 speed swap
For you folks that dont realize, some SA22's came with a 4 speed manual trans instead of a 5 speed...
My 1980 just happened to be one of those with a 4 speed. I bought a 5 speed out of a 1979 RX-7 earlier this year off of craigslist for $40. Yesterday I did the swap.... I had no idea if this transmission worked right or not. It took about 3 hours to do the swap and the 5 speed works perfect!!! Having a 5 speed is great and you folks that have always had one prolly never realized what it would be like without one!!! Before with the 4 speed, 4000 RPM was 70 MPH.....now 4000 is 85 MPH!!!! This will help me so much with those "roadtrips" with the various RX-7 clubs.... No more putt putting because I was "taching" too much.... |
I can't imagine having a 4 speed, even having the 5 speed pisses me off, I really wish 4th and 5th weren't so close together and 5th was taller.

i've never had the 79-80 S model 4 speed and i'm glad. i can't imagine tooling around at 4K at 70mph.

Yeah it is really nice!!! It has not taken me no time to get used to having a 5 speed... I thought I might be driving around and go "oohh duh... I need to shift to 5th"
Funny thing is...I paid $40 for the transmission and it cost me $38.99 for two bottles of Royal Purple 70W-90!! Looking back, I prolly should have changed the front and rear seals, throwout bearing and possibly the clutch.... I had no idea if the transmission would work properly, so I did the swap as cheaply as possible... Oh well...throwout bearing works fine.....clutch still holding good and it does not leak!! |

Now you've actually got to watch your top speed.

True that, if left to its own devices my foot always wants to do 70ish everywhere. That could get very expensive.

I thought the 4-Speed was pretty neat. You don't see alot of them anymore. I dunno if it's just me or possibly speedo's reading innacurately, but my 4-Speed would top 3rd gear out at about 85mph while my 5-Speed in the 83 tops out about 70-75mph. Freeway cruising did seem kinda rough at 4k but it was too sweet to just plant your foot and be in the powerband instantly

I have my "old school" 4 speed for sale if anyone wants one!!! |
Yeah that's what I read an everything was identical driving around town, so that's why I usually chalked it up to an inaccurate SA speedo
|
Going from the top of fourth shifting to fifth, it feels like you dropped about 500RPMs.
Feels like a F1 car. You could even shift that fast! Sort of. |
Yeah it is not a massive overdrive, but enough.... like I said before cruising at 70 MPH was 4000 RPM...now 4000 gives you 85MPH!!!
