Hey guys im selling my old abs system from my ex.....

and some guys wants to know hoe hard it would be to install abs in a non abs Si.

Let me kno thanks

 

its a lot of work
add in not only the brain and modulator, lines, but also speed sensors at all wheels (some hubs dont even have the gear for it)
Theres probably more...but its what I can think of right now

 

So he'd need speed sensors at each wheel, and wiring... what else

 

OMG, it would be cheaper to sell your car and buy one with ABS already in it.

Lets see.

Modulator, computer, lines, wiring, ABS fuse box, driveshafts (with ABS ring) rear wheel bearings (with ABS Ring) wheel speed sensors at all four wheels, steering knuckles (to accept wheel speed sensors) rear knuckles (to accept speed sensors), body wiring harness going to all four wheel speed sensors, and I think even the engine wiring harness is different, and quite often the brakes are differently sized for cars with ABS so that will have to be upgraded at the same time as well.........

In other words, forget it. Unless you have more money than brains....
