Chock At 5ooorpm

[teng]

Stock ECR33 RB25DET. Pulls RPM till 5000rpm and it chocks before going up again. What's wrong? One more question, i have the NISMO 300KM speedometer and i'm stuck at a max speed of 220km. What can i do to make it go all the way to 300km?

What mods you running?

Mine has a nice big flat spot at 5000rpm .. slowly getting this sorted. So far:

replace plugs (.8 NGK Coppers)

tape up coilpacks

ECU reset

Running much better after those, and a cheap way to get close to your RB for an afternoon.

re: second question .. give it more right foot?

stock. i did the ecu reset as well, iridium plugs are new (don't know the gap though). coilpacks cleaned.

I'm gonna send the car to my mechanic this coming tuesday. It seems that now even idling isn't stable. needle stays at 900rpm though, the but the engine sound is not stable.

Did a max speed run just now at final gear at around 200km close to 5000rpm. It won't go any further even when i floor it. Interesting when i saw the engine light come on after 2mins of flooring the accelarator and temp rising above 1/2 line. The engine light went off and temp went down when i release the accelarator afterwards.
