ok now if you where to install a v-afc or get your ecu remaped
just to get rid of the speedlimiter, what is the top speed on
a jdm h22a w/o any mods

JDM Lude

just use the USDM ECU.... no governor.


I have the JDM H22A w/ USDM P13 ECU, and I am gear-limited to 140mph. A stock 4th gen can do 140mph. Stock 5th gen can do 143mph, due to longer gear ratio. (Not sure if 143 is drag or gear limited)

the 5th gen is not gear limited, it is drag limited

4th gen vtec is gear limited to 140 as he said
4th gen si is gear limited to 127 or so

isnt drag limited the same as power limited. what would be the top speed with more hp?

I have got my 4th Gen Si up to 140 on the speedo before, so I don't think it is gear limited to 127.

yes

152-157 is when you would run out of gear
