I know in the FAQ there are the gear ratios for the FC tranny. But, exactly at what miles do these cars redline from gear to gear. My friend, who once owned a GTU '88 says at 7k RPM, his car is at 40mph, but he doesn't remember what afterwards. Also, I know the turbo's gears are a bit shorter, so what do those gears redline at... I'm just curious to see the difference between S4 gears which redline at 7k to S5 NA gears which redline at 8k...

 

interesting question but i have no idea. i can tell you that in my buddies T2 motor NA tranny RX7 he can do like 120 in fourth with a few rpm left and a whole other gear

 

Anyone else? Like, what does 1st gear redline at, then 2nd, then third, and so forth and so forth...

that should help

 

I believe in my 88 t2 i could bring it up to 42mph in 1st gear, with the fuel cut defender.

Go to Mazdatrix and look in there tranny section for ratios. Use the above calculator to answer your question.

 

Mine still has the ATX speedo gear so it may not be accurate:
1st: 0mph to 35mph
2nd: 35mph to 65mph
3rd: 65mph to 105mph
4th: 105mph to 137mph
5th: 137mph to ??? (decreasing speed)

 

If I remember correctly, the top speeds for the S5 NA's were:

1st: 42
2nd: 72
3rd: 103
4th:144
5th: 188

Again, they're not 100% accurate, but I'm pretty sure they're close. But like everyone else said, it depends on your wheel/tire setup.

 

lol 188.

 

With my Tii tranny and N/A rearend, i top out at 150.. but i gets there VERY quick lol
as far as the others not sure, ill have to check
