Holy Crap! (IMG:style_emoticons/default/ohmy.gif) I remembered that the spreadsheet for calculating speed was in this thread and I just calculated 7000 RPM redline for my car in 3rd gear. Its 94 MPH in 3rd and 128 MPH for 4th! 2nd gear is good for 63 MPH. Wonder if I could grab 167 in 5th? LOL!
Trekkor, you were wondering why I was getting nervous going through turn 1 and 10 at Infineon in 4th gear? LOL! Given that I was shifting near redline out of 3rd and had plenty of time to wind out 4th I was going way too fast for my logical brain. Good thing for speedo error or I would have been psyched out. |

I show a stock 3rd "N" at 84 mph (IMG:style_emoticons/default/confused24.gif)
That's on 205/50's, though. How much bigger are you tires and what is the multipler to make the gear chart accurate? Go faster!! KT |

Perhaps I'm missing something - of course I didnt check formulas, just plugged in my tire diameter and 7000 RPM. |

QUOTE(914forme @ Sep 25 2006, 09:29 AM) Ka is stock 5th flipped into third R is created by flipping 4th I'll buy the flipping 5th into 3rd, but can you flip 4th? Aren't the dogs on the wrong gear? Sorry, I'm still figuring out what to do with my silly gearbox problems and I ran across this thread. Kevin |

I'd like to know about the 4th flip as well. The guy that did the 5th to 3rd flip in my transaxle told me told me that the 4th gear set won't swap on the shafts.

I'm pretty sure it ain't possible. I went through my stash yesterday and proved to myself that while 4th and 5th gears are the same and interchangable, they cannot be "flipped" between shafts unless they're going to 3rd because the dogs are on the larger gear.
I have a 3rd N and a 4th N and they have the dogs on different gears. |

Kevin,
I'm pretty certain you are correct remember when I bought that "O" 3rd gear from you. I had to do that because I couldn't use the 4th gear "O" in the 3rd gear slot. brant |
