So this last tuesday i traded my old integra for my first z and im loving it 
im loving this car its a 91 z32 na with only 85xxx original! but i have two problems one is that the speedo read past 160 then once i reach 50 or so lol it shoots up too 135 and the more i accelerate past 50 it almost works backwards any help? and the other problem i have is the power steering cuts in and out and dont know is its the pump or wht it will work some times and not other times 
my z is bone stock and i was wondering if anyone had and input as to how i should mod it like rims, exhaust, engine work, suspension, or if i should keep it na or try to do a turbo swap down the road?
Thank you for reading and im looking forward to you soulutions and opinons!
