k24 RPM limit

[EG5]

Depends what model Euro motor you have. We usually turned it to safe 7400rpm (ECU cutoff). Completely stock K24 motor unopen rocker cover. From factory there about 7100-7200rpm. Im not a K-series expert. Mayb Drhonda will add his 2cents.

I believe Yonas had type R valve springs with the 7800rpm limit.

Single valve springs k24a3 when it ran 11.82 down the 1/4 mile.
Not recomended to rev it to 7800 rpm on stock internal k24a3.
The only thing from k20a2 was crank pulley and 50 degree VTC
7400 - 7600 rpm will be the best rev limit , As power just started to drop on that RPM.


Had my K swap since July 07 , still healthy till today
