Can anyone point me to a chart or resource which shows port timing for the stock 13b-rew.

I need it for both primary and secondary ports.

Thanks....

 

Something like this?

Thank you,

Thats a start, I would love to find something specifc to the REW, I would guess that the 13b 4 port they show is the older cosmo era 13B.

Also I would really like something that has the port timing of the primaries.

What I am trying to do is adjust the sequential injection angle to begin injecting fuel after the port is past the port overlap (if this is possible) to save some fuel.

Haltech e8/e11 are capable of doing this, and independently for primaries and secondaries. I think doing this with larger injectors, especially larger primaries, could save lots of fuel especially on the low end.
