Well, I swapped my s13 redtop sr about 4 months ago. when i plug in the speed sensor the speedo reads double the speed im going.
if im going 20 it says 40..so on and it maxes out on 60 mph. which reads 120 on the dash. it has a fuel cut off after that. any ideas?

i also have an A/c issue. I had custom lines made to fit the compressor on my sr. the thing is that the ac button has a green light which should mean it has a connection but everytime i turn on the a/c i blow a fuse immediately. the a/c was working fine when i was filling it up with freon. but then after that it just keeps blowing fuses. what could it be?

240sx s14 95' SE
with s13 redtop sr20det swap.

thanks for viewing.
