Which Brakes Are Better

the other thing i think worth mentioning is that although the g4's are 8 pot, each piston is very small it almost seems a comparitive force could be made by a big 4 piston i.e the stock brembo gear, it would be intersting to know the total surface area difference between the two calipers...

Good point !

The big advanage is that you get to run a 356mm x 35mm disc and a whole lot bigger pad than standard which helps no end for brake fade as it contains more metal, aluminium bell and a larger surface area. Not to mention the advantage of the mechanical force the larger rotor provides.

I could still brake hard with the standard nissan calipers but heat would get to them in the end. The G4's brakes harder than the standards units i have no doubt about that but you can only brake as hard as your tyres will allow and i found after moving to slicks the standard caliper could just not get rid of the heat fast enough and ended up as brake fade.

Back to the topic of the thread, i was not lucky enough to get brembo on my R32 so for me it was to buy the brembo or G4. Brembo are 10 years old and 324 x 28mm G4 was new and 356 x 35mm with aluminium hats and new pads.

The fact that they seem to work well with the std BMC it would suggest that the total piston area is about the same. Most the advantage comes from being able to run the larger rotor...and hopefully a more rigid caliper.

could you not run a larger rotor with the 4 pot brembo's to give the same effect? or is the slightly larger physical size of the calliper and thicker rotor that help with heat dissapation that make it more worth while?

You could run a larger rotor with stock brembos, but there would be a bit of stuffing around with brackets and the like to get them to work. If someone came up with an easy(and cheap) way to fit bigger discs to stock brembos i'd defiantly consider it. I think the biggest improvement comes from the bigger disc, the bigger caliper/pad probably plays a small part in dissipating heat as well.

I agree with what Troy has said above. But i don't know shit.

Someone lend me the std Brembos with pads for two weeks and i will trial fit them against some rotors i have and see what the max size we can run is. I have some 365mm rotors i can try, also 340 and 355mm rotors we can try them with. Just need the calipers and pads to play with

Why not? mine are sitting in a box for the next 5 weeks, I guess that will be long enough. You definately don't need the discs?

Can send em down with a mate who commutes to melb if you want.

had DBA 4000's on my 32, and ive got brembo-ness on my 33 and thats now cranking near 600rwhp.......but due to running circuit pads in which i have spares of.....im looking for something more streetand softer so they break harder with less warming up time.

Trent can you perhaps helpme out with some URAS pads???

There you go Troy, get Duncans and let me know how you go :D

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
