Ive searched the forum and have noted that 3 people have done this conversion.

This would be worthwhile as the front EVO brembo is larger than a GTR Brembo.

The rear EVO brembo is identical to the rear GTR brembo. This kit fits under a 17 inch wheel and would take 325 to 345 mm rotors.

Also the full set of EVO front and rear callipers are easy to get for about $1200, but its hard to find usable GTR ones at that price.

So who has made up an adaptor to fit the EVO to the GTR, why go through the R and D again if someone knows the answer.

Help anyone.

I have never been able to find out what the piston size of the EVO Brembos are. Personally they are a better caliper as they have an external fluid line and generall newer. But still shitty lug mount and only take a 30mm thick rotor.

A friend and i are working on a budget GTR upgrade, im waiting for pricing back on the billet radial mount caliper that can run between 330-380mm rotors, 6 piston with stainless or alloy pistons as an option. He wants to run the GTR caliper, i am interested in trialling these calipers :)

But, yeh EVO calipers? Need to know what piston size they run, they could be like ht eolder 4 pot Porsche calipers and run smaller pistons which is kind of a step backwards.

(stupid email alerts aren't working for me... hence the late reply)

Front rotor diameter(mm): 320

Front rotor thickness(mm): 32

Piston diameters(mm): 46x2 + 40x2

Caliper piston area(sq. cm): 58.37

care to divulge some details on the budget setup are you working on?

Well the piston area is quite a bit bigger than the Nissan Brembos. 58cm2 as against 53. So expect some bias issues.

Just for amusement this is what the stockies look like at night. :whistling:

My god they are big damn pistons! And info on the rear calipers and the master cylinder size?

The kit i am pricing up is for S13/14/R32/R33/Z32, with a different bracket they should be good for R34 and S15 as well.

I am chasing two suppliers regarding the calipers, one being Kad 6 pots and the other being the Australian supplier of calipers to GM for cars like the C6 Corvette. The rotors will be 343mm for 17" wheels and 365mm for 18" and bigger.

Dollars should come in around $2100 for 343mm and $2400 for 365mm

i'm interested in this, however i'm going the other way.

EVO brembo's are a direct fit onto legnum vr4's, however i've got a set of R33 GTS-T callipers in my shed that i'd like to try first.

they cant be any worse than the 2 piston front/1 piston rear it currently has, and a lot cheaper for me than buying brembo's.

i know the evo brembo's have 130mm between the mounting hole centres, and the 33 callipers i have are 160mm, it's just the distance between the mounting lugs and the rotor slot that i havent measured yet.

I have done this setup on my r32 GTR..A very effective mod. Im running 324mm r34 gtr rotors up front and 320mm 350z rotors on the rear. Running evo7 calipers with Mintex race pads. Huge Huge improvement to the braking and looks mean!.

Im using CNC machined air-craft alloy brackets front and rear. It took me and my toolmaker a while to figure out how to mount the rear calipers strong and safely. I have the CNC drawings or I can get the brackets made up for you.

The front hubs need a slight trim where the factory brake line bolts to. and you will need to run new lines front and rear..I ran braided lines.

The rear hubs are tricky , need to machine a few mm off the inside hub. hard to explain ..but very trick on how they bolt up.

I took photos when i installed the calipers.. but they are on my desktop,ehich has packed a sad...should have it up and running in a few days..

Ask any questions you like as I know this was a long process for me so I dont mind helping out fellow gtr owners. :D

Ive just done this conversion today with a set of 2 piece 355mm rotors. The EVO9 Brembo I used took this size rotor very well and fit up fine with simple adaptors I made up in a few hours.

Im not sure about an bias issues as im running an in car bias adjustor which will obviously be set up at a latter date.

If anyone is thinking about the conversion id seriously recommend it. The brakes are so much cheaper than GTR brembos and the benifits outweight the slight cost of the adaptors

How about the discs by themselves? 365mm

Ferrrari F50 brembo sized rotors.

From what I can see the EVO 9 callipers are basicly identical to the F50's. I have both. There are slight shape variances and the colour but piston surface area looks the same, takes the same pads and mounting lugs are visually the same as well.

I managed to pick up a whole set from and rear with OEM rotors and pads for under a grand so its seriously a bargain brake upgrade.

Add decent pads (I paid 200 bucks) and the rotors which I paid 650 bucks for and its still cheaper than R34 items

Funny, i looked at them side by side and i would say they are similar, but wouldnt say basically identical. The piston size is the biggest difference; Also the width of the bridge is different meaning they wont accept the same sized rotors.

But they do have an external brake line, and are a snug fit over rotors. They are much improved over what Nissan are throwing on the GTRs.

N1GTR..yeh sure, but what thickness are you after?

those seem like really good prices... is that mates rates or legitimate dismantler prices?

for some reason STi and EVO brembos sell for alot cheaper than r33 and r34 gtr brembos.

i have seen complete set of evo brembos for sale on yahoo auction for $1000 + shipping but you would never get that for a set of gtr ones :D

G`day all theirs a R32GTR with evo brembos on it,at L&F i will see the lad`s may be thursday & see if i can get some photo`s,see what their have to say ,hope to put some bit`s on friday,cheer`s chuckie.

i'm interested if the setup fits under a decent--but-nothing-in-particular 17" rim?

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
