Hey guys just going through our shed and ive turned up a set of 32 gtst calipers 4 pots and rotors so hmmm front brake conversion

questions

1) is there a diff between r32 gtst calipers and r33 gtst callipers?

2) and diff between 33 and 32 rotors my memory is not that good think 32 are like 280mm or something not sure about 33

3)would it still be worth the upgrade using the 32 rotors seems there brand new and sitting in the shed

any help would be good

cheers

1) Yes, R32 GTST callipers are suited to 280mm rotors and R33 GTST are suited to a 296mm rotor. mounting bolts and brake lines are the same, just some cosmetic differences, the 32 ones have fins and 33 ones don't.

2) as above, R32 280mm, R33 296mm.

3) its up to you, stock stagea callipers are only 2 pot fronts compared to the 4 pot 32 ones, but the 32's are a smaller rotor than the stock stagea, i think S1 stagea rotors are 290mm. alot of people will argue that with new rotors and a good set of pad the stagea ones are good enough. personally i'd sell the R32 ones and track down some R32 GTR/R33 GTST ones, they are 4 pot and run the bigger rotor.

just make sure you trail fit before committing to installing any of them, especially check the calliper to rim clearance as the 4 pots will stick out about 20-25mm further towards the rim disk.

hmmmm so can any one confirm the size of s1 stag rotors if they are the same size as 32gtst rotors i will prob chuck these gtst rotors and calipers on at least there 4 pots

cheers

so some searching has not helped found a listing for wgnc34 rb25det rotors as 280mm :D but straight under it a listing for wg(n)c34 rb25det rotors at 290mm :) so any one know what the (N) denotes model wise think i should just go out and take wheel off and measure rotors but its cold and late

Pretty sure S1 and R32 GTST rotors are the same size's, as the slotted rotors im running with my stock S1 stag calipers are made for 32gtst

Yep your right measured up rotors today 280mm so will get a set of slotted rotors and use the r32 4 pots i got sitting here

I can confirm this (a little lol) as I run WGNC34 16" rims for drifting on my R33 GTS-t. Rears fit fine (but sit inside the guards like crazy!) but the fronts foul on the callipers as the wheel's offset is too high. It's probably out by about 2mm and can be fixed with spacers, but I'd sooner recommend new wheels :D

    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
