N/A speed limiter

NAdtom · May 5, 2011

i tried searching this and couldnt find an exact answer, i have a 96 jdm supra and i was messing around with a honda on the highway, and he flew past me because i did loose power right around 112mph

. i really would like to get rid of it and i just dont know how to or what really to do. any advice would be appreciated.
Thanks, David.

There is no speed limiter and specially not at 112mph...Maybe the Honda was modified and you're just slow

Where you able to keep going even with the loss of power at 112? Are you auto or manual? I usually lose steam on a flat road around that speed as far as acceleration with my auto 4.28 or so rear end. I've been able to get to 144 in mine mostly bone stock but that took forever.

and from the research ive done looking at them, the u.s model had one but it didnt kick in until 155. japanese was 112. and i was at 180kmh when i felt mine kick in so thats right around 112.

Yeah the JDM is around 180kph. I dont know whether its a "soft limiter" as such though, I guess I always figured it would be like the rev limiter that is a full cut of power.

JDM OEM speed limiter is a complete fuel cut at 180km/h which is around 112MPH. Get a SLD to remove it.

anyone have a DIY for the installation of the SLD?

Delimited mine with a Blitz Power Meter SJ. It's a J-Spec NA AT and was limited to 112 mph.
The J-Spec NA is limited by the speed signal. It's the pink cable on the ECU.

The Power Meter just interups the speed signal. Hope this helps. Otherwise just let me know.
