Most excellent!
Couple more questions: the bottom half of the port is always on - did you consider giving that part only a street port, and having the bridge port only on the auxiliarys? What effect would this have? I'd think then you'd have better low-rpm torque and fuel mileage, with the bridge available when the auxiliarys open - although obviously flow would be limited compared to the way it is now. Also what did you do with the centre housing?
Thanks!

What if i did this kind of porting Judge Ito. What else would i need to do. Give me some tips, I'm all the way over here in Florida, otherwise i'd pass by you're shop and just talk all about rx7's.

Judge Ito, a little off topic, but what do you think of using na rotors with a bridgeported turbo motor..
I was thinking that the higher compression rotors would help to difuse some of the effects of the large overlap at low speeds, similar to upping the compression when fitting a piston motor with a larger camshaft, in order to maintain a minimum amount of low speed cranking pressure, and enable the motor to run without having to advance the ignition in next week and throw a ton of fuel at it to get it to idle... I realize there is less boost potential with higher cr rotors on a given grade of fuel however I am thinking this would help maintain off boost driveability as well..Maxt

Judge that looks nice 
Did you trace? J/K Out of curiosity do you have a dyno there at your shop?
