hey,
1st of all good luck with the conversion all the best.
Please do a write up because i wish one day to do this conversion.
the difference between TA23 and RA23 x members is that the TA curves towards the back of the car where as the RA curves towards the front. one way or the other too dark to go and check out the TA23 x member 4 you sorry but im sure somebody here could clarify it for you.
as for the zoom magazine i think you are talking about the almighty HYP-O77 yes he did recess the firewall back 2in but he also used the original radiatior im pretty sure if you wish to use the supra radiatior you can get away from recessing the firewall.
i would suggest doing a search on these forums or the old ones for a celica brake upgrade or ask around here but you should explain to people what your main use of the car is going to be so people really help you out.
All The Best
