Difference Between PWO & PR3

[1kreationz40]

well just curious...whats the difference from a jdm pwo & a jdm pr3....same rev limit and vtec engagement....both are still ran on jdm b16 correct...i know the pr3 is from the integra xsi, and pwo is from the ef's....but then does it make any difference......?

The pw0 uses a single o2 sensor and the pr3 uses 2. Fuel cut-off is at 8,200 on the PR3.
