1KZ Ignition Timing, how to get more power?

[nelbin]

Hello there

I have a 1KZ-TE engine BUT with 4m40 mechanical injection pump installed.
Installing a mechanical pump with this engine turns it to a beast. My pump is all stock just reconditioned. 140psi on injectors. works great.

Ignition Timing.
I was wondering how do you guys measure the advance/retard on this pump. Obviously timing marks arent gonna help in my situation or is it?
I am looking for more power/more torque. I have read dozens of pages relating to this topic and im abit confused.
Advancing the pump makes more power? but how much more do i lean it?
Do you guys use any tool to measure? by sound? how do you know if it is giving me the peak power?

Thank you.

Advancing the timing from stock will usually net you some power. You don't have a "Stock" setting to go by I wouldn't think with a whole different pump on it. I would throw it on a Dyno and slowly advance the injection timing and see if you make more or less power. It could already be at the limit. You definitely don't want to go to far with it or expensive things could happen. I have done some tuning on my E pump 1KZ along time ago, but I never really dialed it in or knew how far I could push it. I ended up with 152HP and 277Ftlb's. I think I could easily hit 300ftlb, but would it break something?
