no j spec tII is same as US TII ECU so it will hit boost cut over 8 psi
The N/A drivetrain is not strong enough for tII power it might hold if you baby it but what is the fun in that?
As far as the TII trans in the n/a you need to have a custom made driveshaft since the TII tranny is longer than a N/A tranny. mazdatrix makes a tII tranny to n/a rear drive shaft so you would need

since you are the only one answering my questions i was waiting on a response and found out that they made that drive shaft and its like 300 shipped. but what is the cheepest ecu i could run higher boost on?

you can run higher boost on a stock ecu with a Fuel Cut Defender or FCD for short it tricks the ecu into thinking it is still running below factory boost levels which in reality you are not. the bad thing about this is that tunning it is going to require some form of Air fuel computer like an apex i AFC and you are going to need bigger secondary injectors and use the AFC to pull some fuel if need be. 750cc secondaries should be ok for anything the stock turbo will produce reliably i would not recommend anything more than 10-12 psi on a stock turbo. or you can run an AIC (short for additional injector controller and add additional fuel while leaving the stock 550's all around that way car will run like normal out of boost then when in boost the AIC adds the additional fuel required for the additional boost. there many ways you can do it it is a matter of choice.
forgot to add you will need a bigger fuel pump (recommended they are cheap) or a stock TII one should do and a rising rate fuel pressure regulator will help too

The reason why i am the only one answering your questions is because most of these topics have been beaten to death several times. But it is ok with me i know what it feels like to be a noob at RX-7's when i first joined this site in 2003 i knew squat about RX-7's now i know at least 85 % of the magical rotors of death and the fun that comes along with them.
