Advice on 13b-T and SE3P Transmission combo

Hi guys,





I hope that someone can help me.





I am looking to do the series 5 swop in my RX8 and keeping the RX8 6 speed box.





I do have the series 5 5speed box also. I just think it will fit better with the RX bell housing.





My question is, is it possible?





Final hope is the 13b-T with GT35 looking for 400Bhp reliable.





Thanks
