4k redline in a ke70 is apparently 5400 rpm or 5600 rpm (from 2 different, genuine toyota advertising material pieces) with the tacho saying 6,000 rpm.

 

As long as you remember, its a 4k, not a 20B

^^ I concur...

 

5-6k RPM. Rev it til you can feel that its not pulling anymore, then grab the next cog!!

[Rolla__Boy]

Take the car to a shop that has a dyno...and get them to tell you when it hits peak power...and there is never any point in reving it further than that

[love ke70]

mine pulls from 2500 and starts to run out of balls at 5300-5500

but as rolla boy said, get it dynod and see where power falls off

with a stock carb good luck in getting it to give you fuel anywhere after 6000 :)

N/A My 5K runs out of power above 4500 on the dyno...so I only rev it to 6 because of the effect it has on the people I fly past hehe

I didn't know that! now I feel sorta bad for hitting 6800rpm or so :) Really should get a tacho :)

Considering the 4k has its maximum hp at 5600rpm id say that you can rev past that but you wont make anymore power.

[Dave71]

just rev it till interior vibrates, then change, hahaha, you wont blow it up

I concur, If you valve bounce it then it is time to change gear :)

[love ke70]

see people say that, but everytime i do. something goes wrong.

 

for example: coming out of toll booth heading away from Brisbane just been and delivered engine and box to ian, so we had the trailer on the back. i come out and just nail it up to about 6500 and she starts to feel pretty bloody shaky so we change gear, only to find shes now running on 3.

so i drive the 50 KM home with a very sick 4k and in the mornin pull rocker cover off to fnd a pushrod had managed to slide out from under the rocker so no.3 inlet had been jammed shut the whole way home.

 

moral of the story: it was easy to fix and thrashing a 4k is great fun, but theres always somethin thats gonna go wrong :)

lol - love the sig Justin :)

 

Oh those were the days !

 

She aint pullin untill 7k these days :)

stock 4ke ecu has a 6100 rpm redline and all the starlet tacho's had a 6000 redline, so i think that would be about it.........
