Hey guys,

I went into the RTA today and asked about engine conversions, and what’s required etc.

Basically I wanted to upgrade to a turbo-charged engine, However that would require too much effort. So I asked about the Rb25de upgrade, and the fellow said that it was fine as long as the car came out with the same suspension, and brake setup. He told me that I had to get real documents from the Nissan dealer, but being an import I wasn't sure if they would have them.

So basically what i'm after is the stock non turbo 1995 R33 GTS25 specifications. I have a non turbo 1995 R33 GTS which is a 2.0L but I wouldn't think the brakes would differ from model to model.

So if anyone has these details (yes I’ve searched) it would be helpful if I could get them. Also I was thinking about going to the Nissan dealership tomorrow, but does anyone have any idea if they carry this information on their computers?

All I require is the dimensions of the brakes, and basically suspension setup, years released, type of engine etc.

Thanks in advanced.

Dayne :lol:

the simplest way to do it it to swap the brakes from the rb25de donor car. or go to a wrecker and measure the diameter.

you can go the turbo route many have done it my self included (on an r32) swap engine brakes and rear diff and you have have an r33 turbo spec. car ore pricey though.the performance difference from the rb 20 e to the rb25 de is pretty good. my cefiro with an rb25de made 105 rwkw the rb20e would have been lucky to make 70 rwkw.

good luck

btw there is some infomation on these pages on my site

as far as i know the brakes onm the turbo are 5 pot with the brake pads being the same aswell as the rotors being slightly larger. As for the suspension it should be the same, but i think maybe go to one of skylinekids group buys is the way to go, i also think you hay have to change gear box and clutch...

The brakes may be different as i have a R33 gts25 and when i needed new pads the pads for the R33gts didnt fit dont know if thats the information ur after plus a pod adapters for a 33gts dont fit ether i had a custom one made.

my pod filter adapter was the same as an r33 gts25t

the r33gts25 have:

twin piston sliding calipers for the fronts

single piston sliding calipers for the rears

the r33 gts25t have:

four pot sumitomo calipers for the fronts

twin pot sumitomo calipers for the rear

the turbo calipers are bigger and chunkier (from 6 pots total na, to 12 pots total turbo) rotors are bigger and chunkier.

i wasnt asking about turbo, i was asking simply the specifications in (mm's) of the size of the rotars on the Na.

The pod filters dont fit? wtf thats odd.. mine was off a r33 gts25t and it fit straight up. Brake pads..? the brake padds are only listed for rb25de, rb25det and rb26dett in the 1995 skyline range, so i dont see how you could of got gts padds.. maybe the guy just had no idea?

Thanks for all the info though everyone, specially Eug. That was heaps helpful. Just one question though how can i tel the sliding calipers and how many pot they are?

Cheers

give me a minute mate and i'll take a photo of my old calipers

These are R33 GTS25 calipers, they came off my 1994 GTS.

and these are 4 pot sumitomo calipers - these are R32 GTSt , but the R33 GTSt ones look very very similar (minus the ribbed bits on the top)

DSC00659.JPG

very noticeable difference between the two types. (i know you didnt want turbo specs - but just to compare and show the difference)

anyway the R33 gts25 rotor specs for the according to dba are as follows:

FRONTS:

Vented, 280mm diameter, thickness including hat = 49mm, thickness of the rotor disc = 26mm,

I cannot find any specs on the rears, and i dont have my rear rotors and calipers anymore because NA_R33 (John) has them now.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.

      So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
