NSX caliper swap

[PhatAccord]

i actually had a set of those brembo 4 pistons. never got it to work, as i still had trapped rotors at that time. couldnt figure out which rotors would work

The TL Brembo calipers will bolt to the cb7/prelude/odyssey knuckle, but the mounting holes have to be enlarged to accommodate the larger bolts used on that caliper. The amount is 1-2 mm added to the circumference of the bolt hole.

You can use the S2000 rotors as they have the appropriate offset to allow the caliper to mount to the knuckle without coming into contact with the rotor. This rotor will work, although the friction area of the s2000 rotor is not as large as the TL brake pad surface area. In theory you should also be able to use the rotors from the Brembo equipped TL, but I haven't yet tested this theory. The S2000 rotor is 11.8" and the TL Sport rotor is 12.2".

RSX Type-S rotors are the same diameter as the s2000 rotors, but have the same offset as the cb7/prelude brake rotors and because of this you can't mount the TL Brembo calipers to them, but you can run S2000 brake calipers which are lighter and smaller than the Prelude VTEC calipers, but also have a smaller pad surface area. (This is my current setup** and I made the mistake of trashing my S2000 rotors when swapped to the RSX Type-S rotors and now have buy new ones to mount the TL calipers. Also I have to buy new wheels since TSX wheels design/offset will not clear the TL calipers anyhow )


The diameter of the pistons in the TL Brembo Caliper is marked inside of them so that you could calculate the piston area. My TL calipers are in storage, otherwise I would provide that info.

^ nice. too bad my tl brembo calipers are long gone...
but im happy w/ my legend gs dual pistons.
the size of the tl calipers was also a factor for me as well for wheel clearance

So I've seen civics and sol's with nsx calipers and im dyin to do it but nobody has any info on it. Does anyone know where I can find this?? Im Doin brakes and suspension next so this is on top of my to do list. Plus it will look sick lol.

Im running NSX 2 pistons on my coupe...

ive been wanting to do this for some time now, either you would have to source them new. which would be expensive or find them used. basically all you would need is the caliper and rotors when you do Rotor-Over-Hub conversion.

Nope

I didnt not know that. If NSX calipers didnt cost near 450 I'd buy them

Again..NOPE

yea. i would buy them also but they are money. lol.

x 3 wrongo.

Yea man, the cheapest I seen them for was 300 shipped but they were chrome dipped: I have a daily not a hard parker lol


So I poted with the next best thing the legends 122 from my autozone

You just gotta know HOW to look..

No, you use NSX front calipers still. You match the position of them, it doesn't matter where the motor was at in either car. The front brakes are always larger.

I didn't know NSX calipers were that expensive. You might as well get a Wilwood caliper for that price...yeeesh. How does the NSX piston area compare to the Prelude VTEC/ITR/Odyssey/Wagon calipers? Isn't it the same?

Through a dealer its $800 for each side..and thats just the calipers alone.



I get ALLOT of questions when people spot them lurking behind the front wheels. I got a set of remans about 3 years ago for a damn steal.

They bolt up to the car including the brake line..and these bastards stop on a dime.

:edit:



Pics when I first got them..I had them powder coated black.

Get the legend fual piston calipers from an 95 Lengend GS 5spd. The pistons in the legend calipers are a bit bigger then the NSX.

The only thing with the legend calipers is: you need to bleed them off the car because the bleeder valves are positioned wrong. You can't flip the sides because they are directional calipers

The calipers come on

1993-1995 acura legend coupes ( L or LS it doesn't matter )

1994-1995 acura legend GS sedans ( doesn't matter automatic or manual either )

I got a set of NA1 NSX calipers for only $250 last month.
It's really a big deal but there's more than that to have them installed.

First, I repaired them with OEM seal kits and that cost me about $210.

Second, I bought the front caliper brackets of NA2 from Japan in order to
use 300mm diameter rotors and it cost about $180.

Third, the LEGEND front rotors, with a thickness of 28mm, are perfect
and you just need to drill 3 holes on each side for our 4-lug hubs.
Brand new OZ flat rotors cost only $140 and $10 for the drilling.

Fouth, new DIXCEL brake pads for front and rear. Fairly at $180.

And then comes the hard part.

Some custom made adapters are necessary for the rear calipers.
The screw nuts are different, longer, too.
And you need some adapting short metal tubes to hold the calipers
at the right position. That's the most important part.

As for the rear rotors, I'll use the current front VTTR 303mms and
have them modified to a 300mm diameter and 21mm thickness.

Some steps of the procedure have been done but I'm stilling waitting
for the front brackets to have all the set installed.
Hopely they may arrive in this week and I'll try to post some pix then.

Actually if you mount the left caliper on the right, and the right caliper to the left you still retain the directional function. So the bleeder screw is pointing up not down

I just bought a set of NA1 NSX calipers this morning... so a few questions.

Is it safe to redrill the Legend rotors to convert them to be used as a 4 lug?

Do you have to ROH in-order to use the legend front rotors? Because it's something that i'm not interested in doing at all...

After the Legend rotors on, everything else just bolts up? No worries?

- What would be required if I wanted to do the wagon rotors with the nsx calipers? Which brackets? Spacers? etc....

Thanks in advance

I had my front NA1 calipers with NA2 brackets installed last weekend
and it works perfectly so far.
Just drill another 3 holes for our 4-lug and yes ROH is required first.

As I know, NA1 brackets hold 282mm rotors and if the wagon rotors are
also 282mm, then it's all about the thickness issue.
The NA1 calipers origionally carry 28mm rotors and the height is different
from our cbs. So you need to find some rotors with 28mm thickness and
the height should be arround 48mm.
With the proper rotors, it's a direct bolt-on I believe.

Please reply freely if you need more information.

What all will I need for my roh conversion? Will I still be using my same calipers?

Try to do some search and you'll find the answer.

I feel like it should be more complicated.... but essentially just doing ROH conversion but using Legend rotors which have been redrilled to 4x114 and the calipers bolt up.

This + Legend rotors + NSX calipers...

Right?

Let me make it easier.
You have to do the ROH first.
If your NSX calipers are from a NA1,
282mm rotors with 28mm thickness will be ok.
92 or 93 LEGEND Coupe is equiped 282mm*28mm rotors
if I remember correctly...

If you want to go for 300mm rotors, you'll have to use the NA2 calipers
or, like what I did, use the NA2 brackets for NA1 calipers.
I'm not sure if it's easy to find the NA2 brackets in the US
but it'll be a direct bolt-on once you get one.



Pic shows how it looks like with a NA2 caliper and LEGEND rotor
on a 5-lug conversion cb.



And this one shows the NA1 caliper.
You can easily tell the difference of brackets.

No you will no longer retain directional function unless you drive in reverse

the pistons are not the same size

there is an article about it but i can't find it

pretty much the second piston exerts more force then the first piston

One of the piston's diameter is 40mm and the other is 36mm.
The lager one will act first and then the smaller.
