I was just wondering how many RPMs my Civic should be running at while doing 60 mph. I've got a 98 Civic HX (D16Y5) w/ a manual transmission. (I recently converted to a M/T, and just wanted to make sure everything was working properly.)

 

And what trans did you use??

 

A000. Which I believe is the transmission NOT found in the EX/Si.

 

Ok, here's what I found

You can use this to figure it out

well without using this.. I can tell you that most 4 cylinders I've drove ran at about 3000RPM at 60 Mph..

 

I run 3000 at 70mph with a stock setup on a 98 LX. So just a little less should be about right for your question.

 

It does not matter, all d series manual trandmissions through 00 have the same 1st and 5th gear ratio which is .702

 

but the final drive is different.

92-95 Civic DX LX: 4.058 final drive = 60 mph @ 2500 rpm in 5th
92-95 Civic Si/ EX: 4.250 final drive = 60 mph @ 2600 rpm in 5th
92-95 Civic CX/VX: 3.250 final drive = 60 mph @ 2000 rpm in 5th

 

What's the equation for converting final drive or gear ratios into RPMs?
