1jz ignition map help

[kilo_gulf]

almost finished my 1jz/r33 project and need some help with my ignition map, I've looked at a couple of threads to see what type ignition timing people are using on their motors and constructed tne following map. any advice would be appreciated.

the turbo i'll be using is a t3/t67 with a stage 5 turbine wheel (t350) I know the turbine housing is abit on the small side so I purchased a JGS 50mm wastegate. I want to make around 400whp on 15psi with 87 octane (i live in the Bahamas and nobody seems to have a clue what the rating is so i'll plan for 87)
500whp with 20psi and methanol injection

Timing should increase after peak torque (around 4500-5000 on stock cams)..

and for 15 psi on 87 octane, I would start out with 14 degrees around peak and end up around 16 @ 7500 or so.. that should be pretty conservative to start with.

Thatll get you started and then go to a dyno and tune it out.
