geez anything over 80 in my car scares the **** outa me. i couldnt imagine 120.

 

A stock Si should be able to manage considerably more than that, but there is a top-speed governor on U.S.-market Civics since at least back to 1996. My stock '00 VP sedan has managed over 110MPHdown straight, level, secluded roadand it was pretty steady.

I don't really care about innocent bystanders anymore either.

 

^ my 99 DX doesnt have one. Maybe the SI's though (since they're the sport model maybe? idk)

 

99% positive every stock civic has a limit
fairly positive in my 98 dx, it's around 112 or 115

Si might have a limit set at 120

so your 99 not having one, is wrong.... just means you've never gotten your car fast enough to find it

as to the OP, it was answered in the 3rd post...
convert to obd1 w/harness, and have the ecu chipped and reprogrammed....

 

the DX goes until infinity.

 

something must have been wrong with your gauges. you want to fix it up, put lots of stickers.. remember Sparco.

 

+1

 

So you stole an si? Or had one stolen?

 

Looking at the old car magazine tests, all the Civics were drag limited at top speed, meaning their is no governor, the engine just couldn't overcome the drag.

 

i've had my stock ecu 93' civic lx at 220km... but it took a while to get there.. i dont see why you'd really need it to go much faster...
