'01 ABS on a '99?
Anyone know what it would take to install a '01 four circuit ABS with the electronic bias control to a '99? Is it even possible without swapping out the entire brake system?

Count the brakelines, the 01-05 is still a 3-channel system with only one line to the rear.

How much of the 99 harness you can keep and where to cut/splice you have to figure out for yourself.
I have put this on hold, although I already have a 01 pump with pigtail on the shelf and a burned ABS ECU (for connector etc). Someday....

As Niklas says, it's still a 3-channel system. There's no Miata 4-channel system until the NC.
That said, if there were a 4-chnanel system that fit then putting it in wouldn't be much harder than the 3-channel. You'd just have to bend & flare a custom hard line for the driver rear, run it up to the ABS unit, and then delete the junction block and crossover line from the other side.

I don't know if there are any selfcontained (not dependant on CAN) 4channel ABS units, and most probabably none with Miata-like calibration. NC would be closest I guess.
If picking from another car, should it be heavier, lighter, other weight distribution? Preferably tuned for stickier tires (M3 CLS? Close to Bosch Motorsport money...).

As for other ABS transplants, I've heard of people using BMW E46 systems as donors for other non-BMWs, but I dunno if it would work for a Miata. A lot of newer ABS systems are integrated with TC and ESP, which makes it more complicated to sort out.
The 3-channel Miata system works pretty well, I don't know that it's worth trying to do a 4-channel one.
