FSDE head questions

[JLC]

Hello all,
Hoping someone has answers.
1.) what are the combustion chamber cc's?
2.) what are the flow rates on stock port heads?
3.) what are the difference in port sizes between heads?
4.) what is the max power made on an ALL STOCK BOTTOM END?
sorry for all the questions, been searching all over and haven't been able to find any of these answers so I thought that I'd come to the people that would know this engine best in the Mazda community.
thanks in advance
Jessie

1) Math says about 55cc (2000cc/(4*9.1))

2) :/

3) fs9 heads are the same, apart from cams, check link for more info:

4) really depends on tune, cooling, performance, and use. Max is about ~250whp. But that is a very tentative number a simple power figure doesn't tell much information, its more complicated than just that. There are people who have gotten more and people that have broken their cars at a lot less. The connecting rods are the weak link for the most part around that power number kinda becomes just a matter of time.
