would a late 87' (november) TII have high or low impedence injecotrs. and what size fuel injectors should i have for optimum preformace while keeping it drivible (i have exhaust 2 3/4 straight pipe from downpipe, high flow intake filter w/ adaptor, and 10.3mm obx spark plug wires.)

 

i believe s4 (86-88) had high impedence and s5(89-91) had low impedence injectors. I could have it wrong cause i dont really remember anymore, and im sure if a am i will be told im wrong.

and 720 secondaries is a good place to start.
