My speedometer has been pretty much shaking since I got the car 8 months ago and I just replaced the cable recently which fixed the shaking problem. However, is it normal for my gears to be so far ahead? First goes past 40 mph; second goes to 65 mph; 3rd goes to 95 mph, 4th goes past 125 mph.

Should I be worried about this or is that just how long the ratios are?

 

WHat does your butt dyno tell you? You really think you are doing 95 mph on third?

 

Umm... I mean... lol I wouldn't doubt it >.>

Should I post a video?

 

loool wat trans are u using?

 

I'm guessing the trans out of the 2000 GSR it was swapped from. Honestly, I'm not 100% sure and at the time of purchase I wasn't as knowledgeable so I over looked that potential question. Let's create a scenario for both. Maybe it's still the original tranny from the DA and it's 20 years old >.>

 

Got a smart phone? If ya do download a GPS speedometer app or if ya got a GPS usually they will tell you how fast you are going. If you have non of the above have a buddy drive beside you on the highway and compare speeds or something. If you are doing 95 in third then its just the gearing of your tranny

 

its normal for 3rd gear to be 90+

 

Alright, I posted a quick video.

Really? I mean, I can understand 90 but 95 seems a little excessive. So all you guys with GSRs are able to get around 95 mph in 3rd?

 

Nah there is something wrong with the speedo there is no way that motoer should do 140 in 4th gear unless you tached out. i would check the cluster and the cable that runs to the tranny

 

I'm in 5th by 140, 4th goes to around 125. The cable was just replaced.

 

Hmmm seems right actually. If its a b18c1 trans, then 95 in 3rd gear is about right. Ive gone to 120 in 4th at 7700rpm, so yea. I really doesnt seem off. Get your camera buddy to ride beside you at 60mph on his cluster and see what yours says. Simplest thing to do.

 

Tire size??

 

Very good point

 

Most cars are in the 60 to 70 mph range for redlining 2nd gear, and a GSR hardly has "long" gears...

Those speeds for redline are close enough to correct for a GSR. (68 in 2nd, not 65.)

The speedometer reading is taken from the diff, and is only accurate if the tire size is correct (195/55-15, which is 23.3" in diameter).

 

195/55R-15

 

seems normal to me?
lol is it a stock motor?

 

Yeah it's stock. I guess everything is ok then

Thanks for confirming.

 

Seems right to me. Easiest way for me to tell is if you're going 80mph in 5th and your RPM is at 4k, then it's a GS-R trans.
