Idling High

[s13rb20pplater]

so i used the search tool and it hasnt been covered yet.

ive got a rb20 s13 and it idles at 1500revs and when i drive it, the revs go up so fast, and it feels as the car can go faster but the rpm meter will goes to red line, and it feels as if its not getting full power. like ill be at 70ks and the rpm will read 4000k??? WTF!! anyone have any ideas?

engine is stock but has all the usual stage 1 mods like bov, zorst and all the things ricers usually buy first

Slipping clutch maybe?

If you put the car in 4th or 5th gear while doing 60-70km/h and put the throttle to the floor, does the car just rev out but not gain any speed?

Or you've bodged a tacho output signal wire somewhere.

sounds like clutch to me.

should have put a decent on in there when you did the conversion

Have you put a tach adapter in? I6 signal with I4 tach = 1.5 times higher reading...

I use a dakota digital adapter in my RB S14, works like a charm, S13 you can modify the cluster to rear correct though for $80us I would just get a dakota adapter.
