what is the redline for a stock crx si motor???my redline is 7 but my bros redline is 6.5...is it because i still have my hf cluster???

 

i wouldnt go over 6.5 on the stock motor

 

agree ^ high miles?

 

Questions is a little vague, are you referring to the revlimiter/fuel cutoff of your engine, or the instrument gauge tach showing where your redline begins?

The d16a6(Si) motor has a redline of 7100rpm, with fuel cutoff being around there. Fuel cutoff is controlled by the ECU.

If the motor is strong, its probably okay to hit redline every now and then without having any problems, but does it still makes viable power up to 7100rpm?

 

hf redline is 5
