ABS Swap

There's a MASSIVE difference - it would be damn near impossible to swap out to the newer system unless you had a complete parts car to draw from. I looked up the '95 ABS unit swap, and it's VERY different - major wiring changes and the like, and it's just a simple refinement of the existing system.
IMHO, it's just not worth it.

i actually cant stand my current braking system... i have a 94, and it feels like it locks up WAYYYYY too soon, and the pedal just gets mushy and the brakes just suck... i absolutely do not like the ABS in our car (or maybe mine is just broken), but i wont take it out for safetly reasons.
in my miata i have the regular non-abs system, and the car is a BEAUTY to modulate.... i can feel the pads against the rotors through the pedal and it puts you right there... it really helps my braking ability. conversely, if the FD i feel like im a million miles away from the brake system and have very little FINE control over the brakes.... then the ******* just start locking up way before (i think) they need to. i dont know... i hate them.... but at the same time, ive ruined 800 dollars worth of a new set of toyo t1's in my miata with a freak out reflex and just jamming the brake pedal till lockup.... and once you are locked up and panicked its insanely hard to let off and start modulating the brakes. i ruined a brand new set of tires like that and almost got into a nice little accident... so i dont know, id rather have ABS than not. -heath

Locking up? The ABS should keep it FROM locking. Do you mean it just bites too hard at first?
I switch between my FD and miata (non-abs) often. After driving the FD for a while, the miata feels (comparitively) like it has a jammed cylinder or pedal... until I get used to it. I love the FD's brakes, though.
Dale, gotta link about the '95 ABS differences? I've had bad luck searching for that info. The only semi-hard evidence I have is the existance of different part numbers for the front calipers.

sorry... when i said lock up in regards to the FD brakes i meant release (as in when the ABS kicks in). the problem isnt the initial bite... teh ABS just activates way before it seems that the wheels are going to lock up... making hard braking impossible as when i get on them they just start releasing and get all mushy. yeah, i agree the miata brakes are a little hard to get used to after driving the 7 for awhile... there isnt much movement for the miata brakes and it does give the feeling of being jammed or something... i guess im just really used to the crisp feel of the miata though as i drive it daily and have alot of fun with it. glad to see another 7 owner w/ a miata ... i really like both of the cars VERY MUCH in their own ways. -heath

I can't remember all the details on the '95 system. The big change was a much smaller ABS pump, but many of the lines are re-routed, the control system works a bit differently, etc.
I have the '95 service highlights book that outlines a lot of the changes.

Thanks for responding, Dale. It'd be interesting to cross reference part numbers to other models in Mazda's lineup at the time... see if they went to the newer system ('95) purely to consolidate inventory. No big deal, though -- I didn't mean to assign a reasearch project.
As for my '95, I can't say I've ever noticed the pedal get mushy. I've felt it vibrate when the ABS is doing its thing for legitimate reasons, like when going over an uneven road. But then again, I'm not auto crossing it. Are you running heavy-assed 19x10's all around, RotorMotor?

I have a friend (an eletronic engineer) who is probably willing to open it out and study it
I have 2x 93 units to play around with
So he might be able to work something out for us !
It will take time however
