For the waterpump and timing, what kit did you use? Looks good that's the route I'm going with mine. And why are you going to disable the add system and lock it in place if you don't mind me asking.
I too am also interested in an ome kit for my 94 t4r but I'm very new to the Toyota world and know nothing about them. My rig suffers from that super common butt sag. Also is there any other stuff that should be replaced to improve on and off road handling? Steering components?
