16" with 205/45. They came with 16" from the factory so there's either something else wrong or I'm grossly underestimating the wheel/tire combo.

I figured it might be something with my grounds but I'm just putting it off until I have more time to dedicate to it.

You need to swap in an S13 speed sensor. They read differently. The S14 SR came with a 3.69 final drive, most swaps in the U.S. keep the 4.x FD, so the RPMs will be high at highway speeds. Do you have a gps app that can verify how fast you're going at 3,000 rpm in 5th?

I clocked 52MPH at 3000 RPM.

Thanks for the responses, guys. I appreciate you helping me narrow things down.

You might have one of those 4.625 final drives (check killer2001's fs threads as he has some) I think. I might be off on the exact number but it sounds a little too high.



My Subaru has the stock 16's with 205/55/r16 and with a 4.44 final drive (the fifth gear ratio was .7 something, slightly higher number than the .759 in the s14 tranny)

5th gear

-2000 rpm is like 43 mph

-2700 rpm is 60 mph



Speedo reads pretty accurate. Do you have those speed monitoring poles in your city? That's what I use to verify speed





Also for the starting issue, do you dump the clutch to the floor when you start it?
