NO!

The NSX does - maybe the S2000 but doubt it.

when you say 2 piston caliper you mean 1 piston per caliper right?
tls's have 1 piston per caliper

the upgrade kit has 2 pistons per caliper, in other words, 4 piston calipers

Agreed. The TLS/TLP/CLS/CLP use single piston calipers on all four corners.

The number of pistons is calculated per wheel (there is one caliper per wheel). If the kit contains two, two piston calipers (ie. Front Left and Front Right) you still only have two piston calipers, not four.

The ITR has 4 piston calipers....bastards!! And yes we have only 1 piston....correct me if I'm wrong..but don't you need more brake lines for more pistons??

The ones I have seen only use one brake line per wheel. The fluid is then routed to the individual pistons though fluid passages within the caliper body.

The ITR has single-piston calipers as well... I changed the brake pads on my friend's 1998 so I know for sure. I'm not aware of any Hondas that have multi-piston calipers... the NSX might.

Really!?! I thought the guys with ITRs had at least dual piston ones...

I just asked my buddy about his S2000, and he's 99% sure they are single piston calipers. My RX-7 was a Nightmare becasue it was 4 pistons per caliper. Made it a little more difficult. Oh well.

Hmmm...maybe four piston ones have 2 brake lines per caliper...because my friend has his Galant with 4 piston calipers off a 3000gt and he has a couple of brake lines.

Hm... does brake-line # related to # of pistons on calipers?? I have 4 piston front/2 piston back on my 400SE, and I only see 4 brake lines(if those are brake lines I were seeing... heheh... sorry, are not much a tech guy)???

I guess it could vary by manufacturer. I can't picture a 4-piston caliper having 4 seperate brake lines, though.

This was all the info on this site itself and what was released by Acura when the TL-S was introduced. Keep in mind that the 4 channel ABS system has nothing to do with the number of pistons per caliper.
