Bought jacobs FC 1000 They sent me....
 

I bought an FC 1000 for $125 and I got it a week ago, left it in the garage. The box said FC 1000 opened it up today and it was an FC 4000 inside! It sells for $291!! Has anyone ever installed a 4000 instead of 1000?

SPECS:

JACOBS fc 4000 fc 1000

SO MAIN DIFFERENCES ARE:
DIGITAL, REV LIMITER, 50 MORE VOLTS TO COIL, AND 277 MORE MILLIJOULES OF SPARK OUTPUT

EVERYTHING ELSE IS THE SAME.
IT ALSO SAYS PROLONGED STREET USE CAN CAUSE IGNITION BOX TO OVERHEAT RECCOMENDED MAINLY FOR RACE USE WITH MINIMAL STREET USE.

anyone used one of these before? It seems to install the same. Can the coils handle it? TII coils of course. Can the plugs handle it? Car is mostly race and show and will be limited use anyway so I hope it will not overheat too much. I plan on mounting fans to circulate air in the floor pan that I am installing it in so I hope this will help to cool the unit enough.

hey cool beans :D

i haven't done an fc4000, but here's the 1000 install writeup i did:
