this is deffinately a noob question but i gotta ask this about the r34s, are there any differences between the n/a and gtt brakes? and how big the differences are?

another question the n/a r34 brake callipers, do they come with that nissan sign like they have them on the r33s?, my callipers dont say nissan, , i just wanna know if they are aftermarket or just standard? if they are aftermarket theres no real need in upgrading :D lol wishful thinking, anyhows, just shout out what you guys reckon thanks,

i can help you a little bit. when i was looking for an r34 i saw a few at a dealership they both where N/A's one had the normal brakes while the other had the turbo brakes which is the one i bought and i love it. there is a big difference in size, the discs are alot bigger, im pretty sure i have posted up pics of them hear before as well. also they stop way better than my dads ford BA.

turbo brakes have nissan written on them.

non turbo brakes do not have nissan written on them.

- from my knowledge.

scotty from what i remember, youve had a turbo brake upgrade on your car before you bought it!

Turbo brakes are two pot calipers which means two pistons clamp down on the brake pads which are fitted either side of the vented disc brake. In the non turbo case, the brakes are single piston which means your brakes are basically half as good. Im not to sure if the pads are only one side as its a new car (most after 2000 come with double sided pads) but It may be single sided pad (doubt it tho)

In regards to the turbo brakes the disc is alot bigger obviously, even the rear disc on the gtt is bigger than that. bigger disc better braking/faster cooling. hope that helps

Futher infomation the GTV and the GTT comes with big brakes, gtr comes with brembo

Can I ask wtf did you get those impul stickers?

Wouldnt say that 2 piston vs 4 piston, that 4 piston is "twice" as good.

Similar logic applys to brake pistons as it does to engine pistons. Having more doesnt necessarily make it better, but it may do.

If you had two sets of brakes, same size disks, one had 4 pistons clamping down on it each with 20cc capacity (4x20=80cc) (arbitrary values), and the other disk had 2 pistons each 40cc (2x40=80cc) the 4 piston brake wouldnt be 2x better, but it would be better nonetheless.

More pistons disperses the heat, load, etc more evenly/effectivley, and spread the braking force over a larger area of the disk, less chance of the disc warping.

In the case of turbo vs non turbo brakes, yes the turbo brakes are without a doubt better brakes, and are a good upgrade if you can get them at a good price.

Depends on what kind of dba's they are.

If they are just a stock replacement, then the only benifit would be having new discs on instead of older and slightly to heavily worn (depending on how many km's the car has done)

If they are drilled or slotted rottars, then they give the pads more meat to bite in and the car would brake better.

If you car still has the standard GT brakes on them, I would keep an eye out for GTT brakes, find someone with a GTT who is getting bigger brakes and buy their old discs and callipers.

you might be lucky and already have the GTT dba discs and all you need is the caliper.

If the dba's are 908 (rear) 4908 (front) they are just standard GT replacements

the GTT turbos have the 4908 for the rear and 42304 for the fronts.

find out what you have first and then take it from there.

I was just wondering. I heard that the r33 gts-t and r34 gt disc brakes are the same size. Would it be possible to install r33 calipers onto my r34 disc brake without needing much mods done? How hard would it be? Seeing how it would be easier and cheaper to get r33 brakes then the r34 gtt brakes.

Just to set it all straight

R34 GT (na brakes) are exactly the same as the r33 gts brakes, they are a 2pot front/1 pot rear (neither have nissan printed on them)

The R33 gtst brakes are 4pot front and 2pot rear, but are totally different (rotors are larger aswell and calipers have nissan on them)

The R34 GT-T brakes are 4pot front and 2 pot rear, but are totally different to the gtst brakes (bigger again)

If you want to upgrade na R34 brakes, the "bolt on" upgrade is to get r33 gtst rotors and calipers. The R34 GT-T brakes dont bolt staight up, the main bolt hole needs to be drilled out to fit the bigger bolt from the GT-T setup

Will R32 GTR Brakes fit an R34 N/A ? Or is it only really the R33 that converts easily?

^^ yep the whole lot will swap over (rotors and calipers) just as easy

the brake lines do vary though, so everything will bolt up but new lines may need to get made (same for the gtst)

Well I've got a R34 GTT and my mate's got a R34 GT non Turbo. Mine says nissan on the calipers with white writing and the non doen't have nissan written on them. Only the GTT Turbos have the Nissan written on them and the discs are larger on the Turbo from the non turbo.

I'm looking to upgrade my brakes on my R34 Non Turbo as my fronts are 280 and rears are 265mm. Rather than start a new thread I thought it would be best to keep it in this one.

It seems clear that the R33 GTSt brakes are the bolt on way to go, however, a garage in Brisbane that specialises in Jap imports has told me that I'll also need the uprights for the front brakes.

Does this simply mean the upright arms? Or is it possible to just replace the rotors and calipers?

If someone can point me in the right direction that will be awesome.

Also if seems that all the rear brakes are the same and will bolt straight in nothing else needed? If someone can confirm that also?

I'm not so concerned about brake line compatiblity right now as I've been wanting to change them anyway so I'll get custom lines made.

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
