As recommended by the brakes sticky i got some R33 rotors machined down 6mm for my S2 Turbo.

I have found that these DO NOT fit. They sit too far back and rub against the caliper so do not buy them unless you feel like grinding the caliper away, which i am going to do over the weekend. I would recommend going with the genuine items from Nissan or upgrading the calipers.

Have also found that DB1398 pads may fit S2 stageas as well. Will be investigating this option.

If anyone has fitted R33 rotors to an S2 could you please let me know how you got on?

Pretty peeved at the moment having spent about $450 for no gain as yet.

Oh well thats the life of a stag.

I've heard this happy to one of my friend's S1 as well. Potentially it can be dangerous as they rub they will slowly break away preventing sudden stoppage-effectiveness.

Good luck - got pics of your calipers?

The car is an S2, so S2 calipers. DB1398 appear to be the fitment although i have a different brand of pad from japan.

Heres some pics of the gear. The new disc fouls on the back side against the top outside edge of the caliper support.

I think the recommendation should be removed from the brakes sticky but i dunno whether that will happen.

DO you have a pic of where they are hitting, or can you draw up some tricky paint picture? If the rotor is not sitting in the centre of the caliper you can just space it out with some shims, if the disc is too wide in diamter, machine it down a bit more?

Hey there. Ive hacked up an image of where it contacts. Its rubbing on the back side edge of the disc against the caliper support. I think the offset is different to the standard disc and i think the disc might be a bit wider as well so im having my doubts as to whether these are going to work at all.

Im going to see if i can fit the new disc and new pads in the caliper tomorrow. If i can get that to work i think i will see if the disc sits in the centre of the caliper. If it does i will grind the caliper support a bit. If its not centred then i may look into getting spacers.

If the new gear doesnt fit in the caliper then i think i will throw in the towel and have an expensive set of paper weights, im expecting this and after spending about $450 on discs and machining im pretty pissed off about it to be honest, only myself to blame for relying on the internet i guess.

Moral of the story so far is dont trust internet forums to give you the correct parts fitments.

Circled is the contact area.

Righto. Had a bit of a play around today. The R33 rotors will not fit at all without a 5mm spacer behind the rotor. Im not sure if this is dodgy or what. Also i believe the R33 rotor is wider at 30mm when the original rotor appears to be 28mm. So even with a spacer you would need the pads machined down to fit in the caliper.

On the upside i managed to fit new brake pads no worries. S2 pads are the ones in the link below, which are db1398s:

I managed to get a hold of KASHIYAMA [ D1231M ] and they are a perfect fit.

$400 door stops, yay!!

joe, id advise going genuine or getting a hold of some specific rotors from japan, i think there is anything available in nz or aus for our cars.

The dimensions I was given for the front rotors for an S2 Stagea were off an RS4. I have fitted the R33GTST rotors to an S2 RS4 and they fit perfectly (after machining down the 6 mm of course). So I can only assume that the RS-V is different. The way to confirm this is to measure the standard RS-V rotors.

These are the dimensions of the RS4 front rotor (R33GTST in brackets);

OD = 290 mm (296 mm)

New height = 54 mm (54 mm)

New rotor thickness = 28 mm (30 mm)

Minimum thickness = 26 mm (28 mm)

Centre hole ID= 68 mm (68 mm)

Studs = 5 (5)

Obviously the dimension in question is the height (ie; 54 mm).

It is worth mention that ALL R32's, R33's, R34's (including Brembo equipped ones) plus S14's and S15's come with front rotors of 54 mm height.

There was sufficient room (with the pistons fully retracted in the callipers) to fit the Bendix brake padss, ie; the extra 1 mm of rotor thickness (each side), was not an issue.

:D cheers :rofl:

dont Series 1 use DB1398?

perhaps S2 RWD stagea's use S1 AWD brakes?

what size are the S1 stag rotors, 280mm? if so, that S13 disc would be a perfect fit..

however, i have some yellow R33 GTS-T calipers that would suit your car perfectly. :thumbsup:

hahah nice. It looks like 350Z brake rotors are 49ish as well. But 320 OD so thats a no no.

33GTST calipers would be nice, but my R33 rotors are now 6 mm too small for them hahaa.

The 2WD and AWD Stageas have different front suspension layouts, so could this be a factor? Maybe the front brakes are also different between the 2WD and AWD models.

anyone wanna buy some s2 rs4 slotted rotors? :]

Hmm... i'm a bit lost with this, so this WILL fit a Series 2 RS4? And you have a RS-V which require different sized rotors? If these do fit I might definitely be interested. Any difference with front and rear rotors?

Unsure dude. SK says they fit S2 4wd. Not sure if the rear rotors are different between 4wd and 2wd, also this is only the front pair i have.

I think laurel gear will fit my car.

      Link G4X GTTLink questions, MAP Boost Solenoid

      By GTSBoy · Posted

      You've done it wrong. I don't have time right now to type up enough. I'll have to come back to it or maybe someone else will in the meantime. The boost signal has to pass through the MAC valve from boost source (turbo outlet - effectively anywhere between the turbo outlet and the throttle body will do, but closer to the turbo outlet is best) to the wastegate. What you have done is connected it sort of like the stock solenoid. But it doesn't work the same way as the stock solenoid. That Tee piece that you have connected the solenoid to....? The solenoid itself serves that function. You should look up a typical MAC valve connection diagram for a single turbo internal wastegate application. You'll find one easily enough. Every single boost controller manufacturer that uses MAC valves will have one. Bugger it, I'll just grab the HP Academy one. The other thing you have to get right is that the boost source has to be connected to the correct port on the solenoid valve. This is because the solenoid makes the valve switch from connecting 2 of the ports when it is unpowered, to connecting one of those first 2 ports to the third port when it is powered. One inlet, two outlets. You will note from the diagram that the common port is port 3, the port to the wastegate is port 2, and port 1 is the vent (where the boost signal escapes when the solenoid pulses ON). As to the BOV.... the vacuum signal for the BOV simply has to come from the plenum. It must register boost when you're on boost and vacuum when the throttle is closed. That's all. The original location on the plenum is best. Best practice is never to interfere with the vacuum line running to the FPR. Just leave that one alone, as you will avoid causing unintended problems that might occur if you mess something up.

      I was able to complete installation of the G4X ecu. I needed to reroute MAP vacuum signal from stock location to where BOV is connected on the intake plenum. Has anyone needed to do the same? When I connect vac port by the BOV flange to my HKS BOV, it doesnt work and I get flutter. I would to get BOV working, where would it be best to T in? Or would it best for me to move MAP vac line and T into FPR? Secondly, I installed a MAC 3 port boost solenoid and wanted to know if i routed it correctly. I place two lines from stock boost solenoid and placed it on ports 1 and 2, leaving 3 vented. The T for wastegate and boost source on compressor elbow is on port 2, and port 1 is connected to turbo inlet intake pipe. Please see attached pictures. Ill upload ecu config later today. Thanks in advance.

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      So I raised the car up a fair bit for shipping - see image - then lowered it again when it arrived. I then rushed to get an alignment in NL before the track and the shop just wasn’t anywhere near as precise as what I got in Japan. The guys that did the alignment this week said there was a fair amount of toe in the rear that could have contributed to the understeer. It was also the case that the rear camber went from about -2 to -3 at the shop in NL. However, since I’ve now got slightly wider tires in the rear - NS2Rs run wider than Accelera 651S - I could only get a minimum of -3 in the rear now due to clearance. Front is now -2.75 (-2.45 in minutes) due to being raised a bit (previously -3 in JP). So it’s likely a combination of the two factors, camber and toe. The issue now is I have more camber in the rear than the front and the next step on the front Cusco arms will put me at -3.5ish front which seems a bit excessive to me. The weird thing is I’ve never had any understeer at the track in Japan but they are very different circuits - Japanese circuits are much slower than the one I’ve been to here.    I’m probably going to have to start another thread for the E90. The plan is sort of to keep it as a daily but progressively mod it into a track car - honestly, you need a cage for the sort of speeds you go here. Just ordered the M3 front arms btw.  Love the car despite it being in pretty shitty condition. Oil analysis came back okay and it seems to have stopped consuming oil since fixing a load of engine bay things. Saw yours is a 335i right? f**king mistake on my part getting the DI N53 over the N52, fuel economy is insanely good though at 14-16 km/L.   Cheers, it’s great to see the benefits and pitfalls of different places. I’m contemplating going back to the U.K. around next year as the cost of living in the Netherlands is just ridiculous. GF is nagging me to settle and buy a house but I don’t know what LSD to buy.
