Rotors are the same part number (if you have ventilated rear rotors), calipers are the same too, they both use 2 piston sumitomo calipers, so looks like it should be good to go.

Ok I'll have a crack tomorrow and see what happens, thanks for the input!

As silly as this may sound to all/most of you - does anyone know of a thinner

rotor and caliper that will bolt straight on.. For example r32 non turbo rear brakes or r33 non turbo rear brakes, both drilled to 5 stud?

If anyone knows if these or something else smaller than stock will fit without modification I am keen to know :)

Thanks!

R32 GTST including R32 GTR should be 297mm diameter X 18mm thick ventilated rears.

Next down is a 266 X 16 ventilated rear thats hard to find after market....same 5 bolt stud pattern.

In those cases we have been telling customers to send the larger ones to a engineer to have the outer diameter turned down and 2 mm skimmed off them.

Next down is 266mm X 9mm solid, but its 4 bolt stud pattern....

Not sure what calipers they are, the part number for the pads is different, they are not the Sumitomos that the turbo models use with the 2 pins passing through the pads to hold them in.

I have seen a few customers cars come in with them, i think from memory they are only a inboard single piston job, my brake catalog says R33 Non Turbo so i would be looking that way, they are probably a lower level of Sumitomo in single piston.

Concentrate on anything with 4 stud wheels from the R32, R33 range in non turbo is your best bet.

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
