Getting the RIGHT SPEED to Read on Your Speedometer
By Brian Gillespie

Viewer Marco changed the tire size on his first generation CR-V and now his speedometer reads a speed higher than what he's actually going. His tire size is smaller than stock, so this is to be expected. So, how do we correct it? The fix is the same as what we would and have done for engine swaps.

    I've always just removed the plastic cover to the speedometer and pulled the needle out from the pin it's connected to. Then just drive down a non-busy road with the cruise control set to 60 using GPS and insert the needle back in pointed to 60. I've done this on a 2000 Eclipse and 1996 del Sol and no issues.

    Hello vtec gurus, I sent in the original question.. Thanks for the video response.. I did try both the crv and ek clusters and there was no change in the indicated speed, but they are 100% interchangeable in my case ('96 ek, '98 crv).. next thought is to try a vss from bseries civic or integra.. would dseries vss fit the awd crv?

    I have an 05 CR-V 5mt and I just used a tire calcuculator to get it close. I moved from the stock size 215/65R16 to 225/50R18 on 18x8.5 wheels. It's still about the same height at 27" but my speedometer is right on. I'll work on lowering next.

    I had to use a ktuned vss converter between my kpro and the dash. I think I had to adjust it by ~16% to get the speedometer to match the gps speedometer on my phone.
  • @bgee461
    Ive had civic, civic ex, civic si, civic sir, acura el, and crv clusters all in my 98 civic. They all read exactly the same.

    hi man , do you have any pdf guide about swap engines. k20 k24 and also for turbo set up
  • Hey Brian, enjoy the content and love getting any and all information I'm a bit of nerd for stock replacement set ups, but would love to find out if you had any insight, I own a 99 Civic LX currently with Si Brakes, a long time ago there was a person with the handle "Brake Expert" who used to post different Brake set ups that you could use/ modify to work on Honda Civics from 92-2000, more for 96-2000 but stopped after 2006 or so but I was looking for a replacement for ITR Hubs since they were 5x114.3 and was wondering if anyone you knew had tested CRZ hubs. Sadly they aren't sold through anyone other than Honda but as far as Spine to axle and Brake rotor center bore, and are very close on wheel bearing size, they match very closely but part numbers don't match to be a 100% replacement for USDM ITR hubs would this be viable as a replacement for 32mm hubs 5x114.3 hub for a more modern car? or would 8th gen R18 civics fit more closely, no aftermarket companies that make CRZ or ITR hubs to do a 100% comparison of sizes. Would love some insight and your thoughts on this.

    I have a crx with a b16a swap the b16 has a acl oil pump .I use the car for hpde. I noticed that with the stock pcv system I keep blowing gaskets . Like vtec solenoid. Val over gaskets. So I bought a speed factory canister catch can . I’ve tried hooking it up several different ways . Off the back of the block .I removed that then hooked the pcv hose off the black box and the valve cover to it . The issue I’m having now is the van keeps filling up and spewing over . What would you recommend? Would it be a catch can issue or an engine issue?

    Hey Brian, I’m having issues with my shifts from 4th to 5th. I have a k24a2 with the 06 civic si transmission with lsd, ktune shifter and hybrid shift cables in a 96 midori civic hatch. I had the ktuned race shifter cables but I switched to hybrid think it was the cable stretched and the shifter was quite loose.. it’s a bit tighter but still hard to find 5th gear yet. It feels like it goes too far to the right and passes the engagement point of 5th gear. Do you think that the reverse lockout would cause this or is this a whole different issue. Side note.. I had to replace 2nd and 3rd gears and synchros. Found that one of the shifter forks was about to break off so I welded it back together. Any insights would be appreciated. Thank you

    I know on the last video you said the tsx was wrecked, any info you can share with us, I know a lot of people loved your tsx content! Ps just bought a 06 tsx, best car I’ve owned!
  • @Scoots1994
    You can get a speedometer gearbox to adjust the speed. It would require a custom cable if it's a cable actuated speedo. If you want me to dig up the names of the shops reply.
  • @bobbydelamar606
    My speedometer still doesn't work on my 1989 CRX but you answered my question. I need some kind of converter. Bad thing also is Hondata is not reading speed either.
  • @Solefresh10
    There’s a speed correction in kpro.. but can’t seem to get it to work
  • @dantheman1689
    Would love to Kswap my GK5 but keep it automatic. How much more difficult or easier would that be and would the same engines be an option despite having an auto transmission?
  • @r2stik
    17" 45 factory. 17" 50 ok.
  • @joseroman2385
    I wish i could find a speedometer for 20 or 30 bucks. Who's your supplier.😂
