4 Piston Brakes???
My 91 N/A is a 5 lug car with single piston calipers. I already have the four piston calipers from another RX-7. Does it all bolt right up? I tried searching I couldn't get any concrete answers.

The both cars have vented front but the single pot car has non-vented rears.. the 4-pot car has vented rears....
The fronts will bolt straight over as long as you retain all of the caliper-side hardlines. The rears need the entire hub assembly to be swappe.

Sorry, you're right, keep the rubber pieces with the calipers, and just disconnect and reconnect from the brake tubing. I did it on mine, but it's been a couple of years, and I ended up having a mechanic finish the rears because I couldn't get the axle nut loose.
I took the center cap off and used a 24" breaker bar, and a 4 foot fence post over the top of that, and all I did was bend the fence post and lift the entire rear of the car off the ground.

Is the single pot 4 lug wheels?

I think the s5's were all 5 lug. I actually switched to the TII 4 pot calibers and rotors because it was the same price to upgrade the brakes AND get new wheels as it was going to be to get the same wheels as 4x114.7 with that offset.

sorry to dig up an old thread, but i'm in the middle of doing this... brake rotors in the front are the same for single and four piston, correct? but i'll need the flexible brake lines for the four piston brakes....

The front 5 lug rotors are all the same, you don't need to change them. You do need to change the rear rotors, but if you've already got a 5 lug car then no hub swap is needed. You can use single piston brake lines with 4 pot calipers if you don't use the caliper hardline, it fits perfectly.

Since we're on the subject. What exactly has to be done to swap the rears. I thought all you needed were the rear calipers and rear vented rotors, and brake lines. What else would I need?

Hate to resurrect this thread, but if I started a new one I would just get "Search noob, this has been asked a million times!" Well I did search, and found half of what I needed to know.
I have a 4 lug s4, I just got a 5 lug swap (just hubs/spindle) from an 89 base (5 lug, single piston front, solid rear) and I got the 4 pot fronts from someone on this board. According to this thread I can use the front hub I got with the 4 pot with no problem, just need the 5 lug vented rotor.
For the rear, I would need to get a different bracket if I wanted to use the vented rears (according to my searching and the above post).
On to my question, would my 4 lug rear calipers bolt onto the 5 lug hubs/brackets and work with the solid rear rotors, or would I need to get the caliper from the 5 lug base with solid rotor? I don't want to have to source out the brackets for the 5 lug vented if I can use what I have.

It looks like the solid rear brakes were the same size so I think you should be fine to use the S4 stuff.

Just so your clear, if you wanted to use the rear vented rotors you need to change the bracket AND the caliper.

i'm pretty sure the 4 lug S4 and the single piston S5's have the same rear brakes except that the S5 is 5 lug, instead of 4.

I got 4 pot fronts to replace my singles back when I first got my 89 GTU. They bolt right up. Rebuilt them, bought new rotors, installed ss brake lines in place of rubber, and got some better pads. Might as well do it all. Rears stayed the same. Changing up rears didn't seem worth the trouble beyond the SS lines and new pads.
