You could upgrade to this wheel

Also you mentioned that your EGTs are increasing disproportionately in top end. Maybe better exhaust setup is what is needed.
Given that 67mm billet is proven to flow north of 90 lbs/min, you should have at least another 100 HP in there.
Its shame that most people don´t realize, that you have one of the most powerful street driven rotaries around. Reading today´s internet forums makes me think, that people forgotten why they are modifying cars at the first place. Why give credits to guy who have genuine 600+ HP 13B when there are dozens of monkeys which claim 700+ and never back it up?
