On a B16a swap im goin to do to a 91 civic dx, which of these are better.

ECU- - PR3 or the PW0?

and

Cable Tranny- - Y1 Or S1 Or the J1

Vs The LSD Tranny?

i dont know much about the ecu's i know for cable the Y1 has the shortest gear ratio, but i dont know much else.
and the Limited Slip Differential or LSD is better to distribute the same amount of power to both axles, but thats about it, can anyone fill in the blanks for me?..im not really caring about the LSD, basiclly just the Y1, J1, or the S1

thank you guys for takin the time to clarify this
