Ok, did a search and couldnt find info from anyone whose done it...so ill ask the q's ive got here....

I need new rotors and new pads for the r32 gtst. I understand r33 rotors are larger, and that the r32 calipers are up to the task...

So i want to fit r33 rotors (or the largest i can fit :D ) with some freshly rebuilt r32 calipers, using new pads...heres the q's :angry: :

1. Looking at the www.dba.com.au website, can anyone tell me whats the part number of some r33 rotors (DBA4000 series, wiper slotted surface, with kangaroo paw inner)? Or can i go larger in size? (currently have 16" rims)

2. Where can i get the new caliper mount to offset the larger rotor, and do i need one?...also how much should it cost? :angry:

3. Anybody got the workshop diagrams for the r32 calipers, so i can rebuild them? Is it hard to do yourself, or best left to a workshop?

4. How hard is it to swap the rotors etc, yourself?...

:lol: cheers

Your GTST will have 280mm rotors, the R33 uses 296mm and R34 310mm. You can run the 296mm rotor, but you will need to use the R33 caliper, did the 310mm ; you will need the R34 caliper.

Problem with trying to use a bracket to offset the rotor that is only 16mm bigger, is well condider the bolt holes are somthign like 12mm, so by the time you drill the two holes next together, there isnt goign to be much meat in the bracket between the hole centres :angry:

So the best bet is sell the R32 caliper and rotor to an S13 owner, and put that money towards soem R34 GTT calipers, then run something like the DBA4000 rotor. (or std rotor if its till in good condition)

Next best bet is grab R33 or R32GTR calipers, check the condition of the seals and pistons etc. And throw on the DBA4000 296mm rotor.

I think the 310mm may need 17" wheels, never really checked though. But if you want to use the R32 caliper you currently have, then let me know what budget you have as i may be able to sort a nice curved vane 324 x 30mm rotor with adaptor to offset your caliper for reasonable price. Are you after slotted, slotted/cross drilled????

2. Where can i get the new caliper mount to offset the larger rotor, and do i need one?...also how much should it cost?

See above

3. Anybody got the workshop diagrams for the r32 calipers, so i can rebuild them? Is it hard to do yourself, or best left to a workshop?

Take the caliper off, and give them a clean..all will be revealed. its not difficult to re-co them and inspect them yourself. Th eonly tricky thing is the grease you use for re-assembly

4. How hard is it to swap the rotors etc, yourself?...

Piss easy, two bolts holf the caliper on, remove brake line if your goign to service the caliper and the rotor should fall off. If it doesnt the rotor has a tapped hole that you cen screw a bolt into to help pry off the rotor if they are rusted on. Just check everything is tight when all goign back together :angry:

Oh...and remove the dust shield while you are there...cut cut cut :D

r32 gtr would be an easy upgrade, straight bolt off, bolt on. all you need is the discs and calipers. I've got some in my shed you can have a look at, quite a bit chunkier than the ones you've got now. I dont want to sell mine, but you can have a look to get an idea how they differ.

Oh, and to make the job all that cheaper, I have a mate that would be interested in your current set up.

Cheers Troy, was hoping you'd see my thread :P

Im interested in the 324 x 30mm rotor with caliper offset mount...but would it need 17" rims to fit as well Troy? I really dont have the cash to upgrade rims atm, but 17" are on the list...or better 16" rims (still undecided on that path). If the will fit the 16" rims, tell me more :D

Im after slotted rotors only...

So the best bet is sell the R32 caliper and rotor to an S13 owner, and put that money towards soem R34 GTT calipers, then run something like the DBA4000 rotor. (or std rotor if its till in good condition)

Next best bet is grab R33 or R32GTR calipers, check the condition of the seals and pistons etc. And throw on the DBA4000 296mm rotor.

So as long as i use the caliper that is normally used with the rotor, you just bolt them up? The caliper mount stays the same?

Oh, and to make the job all that cheaper, I have a mate that would be interested in your current set up.

Will let you know mate, depending on what Troy can do for me.... :D

im using 32 gtr calipers as new 4000 dba discs will be very similar costs for all three options and pads are the same so have a look around for some cheap calipers for sale, it will be cheaper i think to buy some gtr 32 calipers and sell yours then you can use off the shelf rotors with no adapters needed, add some braided lines and good pads and your set. I dont think there is any need for anything larger in a 32 unless you do serious track work

I have noticed with the bigger motor i need to pull it up a tad harder these days :P Pads dont last as long either....

I guess id like an easy upgrade, and the way others have said to sell my gear, then go larger calipers and off the shelf rotors seems nice and easy....

What kind of grease is needed? I think ive got a fresh jar of high temp. grease...HTB? is the one i got...its grey in colour. Will look later to find out.

Why do i want to remove the dust shield?

Dust shield generally means higher brake temps...not a bad thing on the street where you want your brakes to come up to temp quickly and be ready for that one big stop when required. But in spirited driving they get too hot all by themselves so every bit of free cooling is good.

As for the 324mm they do need 17' wheels. Its up to you what you want to do, the 296mm would still be a good upgrade....and i think the bigger rotor gives a nicer feel under brakes...others that have driven the car seem to say that it stops nicely..actually you have driven the old girl, though i cant remember what pads i had in ti back then, i think they were jusr RB74s.

Ill do some numbers and shoot off an email reagrding some options other then the DBA route...

As for the grease...i got no idea, all i know is that it not the sort i put in my hair...

Perhaps ring the local brake joibt and just make out liek you know the stuff; yeh, yeh, just some of the grease for the caliper pistons thanks, yeh you know the one" :P

Actually did a search, and its not exactly the same for the Nissan caliper but its close enough to get you goign, and with the caliper in front of you, well you can easily suss out the rest

Cheers Troy :P

Looks like i need to use some Castrol GRRB grease... :Castrol GRRB

A rubber compatible castor oil-bentone based grease ideal for packing rubber dust covers of hydraulic and mechanical brakes. Also ideal for use on rubber seals during brake assembly.

Sounds the one, years ago when a friend adn i were doing a 200SX i think we used PBR...but sounds like the same thing. Interesting to read that BMW How to suggests just to use brake fluid, makes sense i suppose...i popped a pston out the other week when i was tryign to rush a fluid and pad change, only i forgot to put the pads in, and upon haivn to put th eiston and sealetc ack in, it appeared that Race Brakes had used grease after i had my calipers HPC coated

But what happens when water gets inside your calipers? Brake fluids hygroscopic(?), & your pistons wouldnt be as "lubed up" after a period of time, then would sieze if not serviced regularly...

Ill stick with the grease still :P

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
