Majority of the caliper types would have been 4 piston front and 2 piston rear calipers.

Nissan branded Sumitomo calipers.

R32 GTR V-Spec / V-Spec II

R33 GTR / R33 GTR V-Spec

R34 GTR / R34 GTR V-Spec / V-Spec II / N1 / Nur / M-Spec

Would all have Brembo calipers.

If you are referring to the material used to make the rotor, I believe most would be cast iron.

Not till you start buying aftermarket rotors they start using alloy metals.

No, the question was which calipers are alloy and which are iron.

Regardless of which are which above, you cannot run the bigger GTR calipers on 280mm diameter rotors, because the caliper does not sit over the rotor properly, it hangs off the outer edge. The R32 calipers need 296 mm rotors (and so you could run them on the R33 rotors which are 296x30). The various V-spec rotors/calipers are for even bigger diameters and so you can't mismatch them onto smaller discs either.

The length of the legs of the calipers is the main difference. R32 caliper is essentially the same as the R33 caliper, but the R33 has longer legs to suit the bigger disc.

All of this becomes a bit more flexible if you're going to be using struts that will need an adaptor to mount the caliper anyway. What were your plans?

I must have missed his post while posting my answer.

Or I would have known :)

and i've adapted a 280mm x 30mm rotor to my strut, i heard the r32 gtr calipers are alloy but it looks like they run a 296mm x 32mm rotor, is it possible to run the gtr caliper with my 280mm rotor??

Like what GTSboy said.

If you want to run R32 GTR calipers run the R32 GTR rotors.

thanks heaps for that and which one are cast iron and which are alloy?

Generally the Skyline ones are alloy, the S-chassis are all iron. There is a significant weight difference.

ie. R32 GTR, R33 GTST, GTR, R34 GTT, GTR are all alloy.

S13, 14, 15 are all iron.

Unsure of R32 GTST material. There is a silvia page somewhere on the interwebs which describes all this and more.

      RB20 in need of modest love injection

      By GTSBoy · Posted

      As you're looking at using a Link ECU, then large injectors are not a problem. But there's not really any need to go 1000s on an RB20 unless you're planning >>600HP on E85, which would seem unlikely. There are other options for injectors. The Xspurt ones are available from a number of places and you can get them in the mid 600s and 725cc, which is probably a sensible place to be. These are all EV14 based. If you are not using the stock AFM (at all, which would be the case with a Link) then a large turbo intake pipe to suit the ATR turbos is not an obstacle, so you should use one instead of a highflow. Results will be better.

      RB20 in need of modest love injection

      By QB6SAGR · Posted

      Hey guys,  I'm after some advice and this here is the best place to get it imo. I was a member a looong time ago under another account, with a lost email address. Its nice to jump back on and see some of the same names still giving good advice.  I mothballed my car when i moved to perth in 2013, and after getting towed across the nullabor a few times it has officially done more km's on a trailer than under its own power. Now that i have started the process of tidying up and modifying it, i see the fruit available (and the fruiterers selling the produce) is different than back in the day. hence my questions, as i used to 'know' what to get and now, i'm not so sure. Engine wise the car (92 gtst) has a walbro 255, k+n, fmic, cam gears and and turbo back 3"exhaust. Wish list is a Hypergear high flow or ATR43G1, Link G4x and some newer injectors before a tune up. My goals are modest, only low 200's power wise. i know i could achieve this with less, but i've been swapping out old for new where i can. Every cooling hose has been replaced, along with mani gaskets, WP, thermostat and radiator, fuel pump and timing belt, tensioner and idler, and i rebuilt the steering rack. Regarding the injectors, the fruiterers all seem to sell what used to be considered quite large injectors. There are a lot of options for bosch 1000cc EV14's, and i would like to know if that is a suitable choice for my build. Is modern injector design good enough to run these at the low duty cycles that i likely would be? is there a downside to running a too large injector these days? or, would there be an upside to running a smaller injector at higher duty cycle? I can see that there are smaller injectors still available, but the ones i have seen specifically marketed for RB's are pretty large (see: https://golebysparts.au/collections/fuel-rail-injector-kits/products/nissan-rb20-fuel-rail-bosch-980cc-1150cc-injectors-turbosmart-fpr800-regulator-kit), and i dont know enough about them to say one not marketed for RB's would fit or not. I have searched the forums, and amongst all the posts on older tech, I did see gtsboy recommend EV14's, but no size was mentioned... again, i'm not clear on if the smaller size bosch injectors are also EV14's as they do look similar.  also, if someone can recommend a tuner familiar with RB's in the Geelong or West Melbourne area i'd appreciate it. Thanks in advance guys. Cheers, Rowdy

      R33 GTR lift points for hoist

      FWIW the depth of the groove in the rubber pad is not super essential, the blocks are rubber and squish a bit. If you are worried an angle grinder will make a deeper groove quick smart

      I mean, if you were to move the jacking points away from the original location, that is, away from the wheels and closer to the centreline of the car, then it will be more likely to overbalance and tip off the supports. Same as we talked about before. I was talking about moving for-aft. If the sill is bent outward or inward, then the car would obviously look unstraight from the outside. Hopefully that hasn't happened either. Again, you can do comparative measurements from the chassis rails to see if there is much deflection.

      Can you elaborate what you mean with your first sentence? I meant move as in the bulge kinda seemed like it got pulled "outward" meaning it got pulled down and to the side with the jacking rail itself, so the load bearing bulge now sits lower than usual and is not level with the sill on the other side of the jack point. Either that or the jacking rail just got pushed in a good bit.
