my 33 handles great. and theres no expensive coilovers. most would say it's set up wrong. the car is too low, and the springs are very hard. besides the bumpy ride, it handles great. i'm running 235 fronts and 265 rears.

my point is, imagine if i had an expensive/renowned suspension set up.

i'd have to say skylines handle well.

Soz to kinda hijack this thread.....MANWHORE you mention tyre pressures. I run 36psi front and 34psi rear on 235/40/18s. does that sound right. the car handles pretty well even with stuffed shocks (waiting for funds to buy HKS hyper max 111s)

ANdrew

i'd be running 38 - 40psi on 18's

reason being, low profile = smaller sidewall. higher pressures keep the sidewalls firm.

My old R32 GTR runs most track days with the name super cars, ferrari 360, 430, 599, porsche 993, 996, 997 turbo, 996 & 997 GT3, 997 GT3 RS, 964 3.6 turbo, lambo's of all kinds ( not even going to attempt to spell them ), BMW CSL M3, aerial atoms, caterm, Audi RS6, whole gaggle of evo's and subies.

And to date the only cars that out perform the old girl are the Z06 corvettes, porsche GT2, Carrea GT2 and SR3 & SR8 radicals.

Has to be said though that the slicks made a huge difference to the car,there is not a lot of straightline difference ( except those bloody Z06 ) its through the twisties that my car makes ground on them.

i'd be running 38 - 40psi on 18's

seems a little on the hard side but i will give it a go an see how it goes

Its not too low, u probably find it feels bad because as you said u have fairly average suspension mods and use the extra pressure to mask this and make the car feel more nimble.

cheers tho

Exactly, I use 38psi because I've still got standard suspension on the front and too soft stuff on the back. Why would smaller sidewalls need more pressure to be stiffer? Wouldn't that be the case for larger sidewalls, which inherently have a lot of give in them. Munkyb0y, if you have some sort of proof to back this up then please let us all know, but it doesn't sound that logical to me. 36psi is fine - try anything in the range of 32-40 and see what you prefer with your setup.

Edited by aDrew_C

this is pretty basic stuff. smaller sidewalls need higher pressure. ie, 19's would run 40-42. 17's would run 32-36

check out the tyre placard on a car that comes with 18's from factory. it will have a recommended pressure of around 38.

my mates FPV had 19's, recommended pressure was 40-42psi.

dont let me tell you what pressure to run. do your own research. i have, and i run 38-40psi all round.

No mildly worked skyline gts is ever going to handle great. They're just too big and heavy, an equivalently modified GTiR, Glanza, wrx etc. is always going to leave the gts for dead. I'm very much a fan of skyline's but I know my car is no world beater.

Before I got my full SK setup I'd admit the handling was not impressive at all. I'd even say my parents BA falcon handled better, that's kind of bias though as my car has 11 years of wear and tear on their's. After I installed the new suspension there was a big difference, I'd say the handling is now good and representative of what a skyline should handle like.

The shocks are either stuffed, or they're not stuffed, or they're semi stuffed. IF they're stuffed, doing your tyre pressures isn't going to make it handle well. It'll make it handle as good as it can, with those shocks.

On the street, I run 32/33 psi on both the front and the rear.

i wouldn't discount the handling of the bentley too much - they are worth big money for good reason, they're engineered to the eyeballs and the big weight and unassuming chassis can probably do better than you think. a well tuned suspension/tractioned skyline is surely pretty formiddable, but out of the box, the stock bentley would kill a stock skyline. those things, like most super-luxury cars nowadays hammer!!

that being said, if i was going to spend that sort of money on a car, you can bet your ass it wouldn't be on a bentley

Sure, you would hope that the bentley would have more engineering than the skyline. I'm not saying that bentleys are good or no good, I wouldn't have a clue. But what I can say is that with expensive name cars, the ratio of engineering to cost does not go up linearly. I'm sure you would agree that a lot of the money goes into the name.

Like lets just take an example. A bmw 318i. IMO, it's a piece of junk. No power. No luxuries (everything comes as an option). nothing special in terms of driveability. That car is probably the same amount of 'car' as a mitsubishi lancer 4 door, yet costs 3 times the price.

hey tacker I've been meaning to ask, what sort of power do you have at the wheels? all you need is say 400 and you will kill those corvettes in a straight line and in corners, guys over here like giant are making great power and turning out amazing times in full weight cars.

For road tyres I use between 38 and 42 as well, so try out at that level and see what you think.

Woot. I started a flaming race. Whos Next?? I think I'll stick to my 36 front 34 rear as the tyres seem to have even temperature across the surface and more importantly even wear.

Appreciated though

Good stuff, I run 38-40 all round also, but I thought I might just be preferring this because of my sloppy suspension.

Cheers

Sorry for the hijack will make up for it with crackin clip.

Duncan i have about 450 hp at wheels or so the sub zero dyno told me. And absolutly no chance of getting near those bloody Z06 corvettes. 7 litre ( 505hp ) and grillions of torque. they are 60% carbonfibre and weight less than 1200kgs. They are not the C5 C6 normal corvette, i can deal with those :-)

Anyone want to travel over they have have a crack at them have plenty of room.

grip and handling are different. handling is the behaviour of the car at the limit. All wider tyres do is raise the limit.

The RSPCA is going to ask me to stop doing things to that dead horse soon..

Yes .. but handling includes oversteer and understeer as well as body roll etc.. with a wider tyre you will most likely drastically reduce slide enhancing handling.. But this goes hand in hand with tyres

In regards to tyre presures.. A good general rule is use is 10% minus you max presure..

I.e 44psi max = 39.6PSI (offhand if i remember correctly) so rounding up to 40PSI for good wear and good handling ..

Just tested this theory with good results in my car with nan krap (kang i mean) went spinning around tight corners with 40psi vrs 36psi and the difference was huge..

personally I think nankrap tyres are really bad, blown up to 40psi I could come out of corners with no wheel spin and fast and it also reached higher rpm before wheel spin in first 5,600 vrs 4,700 they are also about 20% tread..

But I assume this will not work for everyone however I nicked the idea from the tyres guide someone posted a link to one day.. just felt like testing it

I have no results for tyre wear.

    • Any update on this one? did you manage to get it fixed?    i'm having the same issue with my r34 and i believe its to do with the smart entry (keyless) control module but cant be sure without forking out to get a replacement  
    • So this being my first contribution to the SAU forums, I'd like to present and show how I had to solve probably one of the most annoying fixes on any car I've owned: replacing a speedometer (or "speedo") sensor on my newly acquired Series 1 Stagea 260RS Autech Version. I'm simply documenting how I went about to fix this issue, and as I understand it is relatively rare to happen to this generation of cars, it is a gigantic PITA so I hope this helps serve as reference to anyone else who may encounter this issue. NOTE: Although I say this is meant for the 260RS, because the gearbox/drivetrain is shared with the R33 GTR with the 5-speed manual, the application should be exactly the same. Background So after driving my new-to-me Stagea for about 1500km, one night while driving home the speedometer and odometer suddenly stopped working. No clunking noise, no indication something was broken, the speedometer would just stop reading anything and the odometer stopped going up. This is a huge worry for me, because my car is relatively low mileage (only 45k km when purchased) so although I plan to own the car for a long time, a mismatched odometer reading would be hugely detrimental to resale should the day come to sell the car. Thankfully this only occurred a mile or two from home so it wasn't extremely significant. Also, the OCD part of me would be extremely irked if the numbers that showed on my dash doesn't match the actual ageing of the car. Diagnosing I had been in communication with the well renown GTR shop in the USA, U.P.garage up near University Point in Washington state. After some back and forth they said it could be one of two things: 1) The speedometer sensor that goes into the transfer case is broken 2) The actual cluster has a component that went kaput. They said this is common in older Nissan gauge clusters and that would indicate a rebuild is necessary. As I tried to figure out if it was problem #1, I resolved problem #2 by sending my cluster over to Relentless Motorsports in Dallas, TX, whom is local to me and does cluster and ECU rebuilds. He is a one man operation who meticulously replaces every chip, resistor, capacitor, and electronic component on the PCB's on a wide variety of classic and modern cars. His specialty is Lexus and Toyota, but he came highly recommended by Erik of U.P.garage since he does the rebuilds for them on GTR clusters.  For those that don't know, on R32 and R33 GTR gearboxes, the speedometer sensor is mounted in the transfer case and is purely an analog mini "generator" (opposite of an alternator essentially). Based on the speed the sensor spins it generates an AC sine wave voltage up to 5V, and sends that via two wires up to the cluster which then interprets it via the speedometer dial. The signal does NOT go to the ECU first, the wiring goes to the cluster first then the ECU after (or so I'm told).  Problems/Roadblocks I first removed the part from the car on the underside of the transfer case (drain your transfer case fluid/ATF first, guess who found out that the hard way?), and noted the transfer case fluid was EXTREMELY black, most likely never changed on my car. When attempting to turn the gears it felt extremely gritty, as if something was binding the shaft from rotating properly. I got absolutely no voltage reading out of the sensor no matter how fast I turned the shaft. After having to reflow the solder on my AFM sensors based on another SAU guide here, I attempted to disassemble the silicone seal on the back of the sensor to see what happened inside the sensor; turns out, it basically disintegrated itself. Wonderful. Not only had the electrical components destroyed themselves, the magnetic portion on what I thought was on the shaft also chipped and was broken. Solution So solution: find a spare part right? Wrong. Nissan has long discontinued the proper sensor part number 32702-21U19, and it is no longer obtainable either through Nissan NSA or Nissan Japan. I was SOL without proper speed or mileage readings unless I figured out a way to replace this sensor. After tons of Googling and searching on SAU, I found that there IS however a sensor that looks almost exactly like the R33/260RS one: a sensor meant for the R33/R34 GTT and GTS-T with the 5 speed manual. The part number was 25010-21U00, and the body, plug, and shaft all looked exactly the same. The gear was different at the end, but knowing the sensor's gear is held on with a circlip, I figured I could just order the part and swap the gears. Cue me ordering a new part from JustJap down in Kirrawee, NSW, then waiting almost 3 weeks for shipping and customs clearing. The part finally arrives and what did I find? The freaking shaft lengths don't match. $&%* I discussed with Erik how to proceed, and figuring that I basically destroyed the sensor trying to get the shaft out of the damaged sensor from my car. we deemed it too dangerous to try and attempt to swap shafts to the correct length. I had to find a local CNC machinist to help me cut and notch down the shaft. After tons of frantic calling on a Friday afternoon, I managed to get hold of someone and he said he'd be able to do it over half a week. I sent him photos and had him take measurements to match not only the correct length and notch fitment, but also a groove to machine out to hold the retentive circlip. And the end result? *chef's kiss* Perfect. Since I didn't have pliers with me when I picked up the items, I tested the old gear and circlip on. Perfect fit. After that it was simply swapping out the plug bracket to the new sensor, mount it on the transfer case, refill with ATF/Nissan Matic Fluid D, then test out function. Thankfully with the rebuilt cluster and the new sensor, both the speedometer and odometer and now working properly!   And there you have it. About 5-6 weeks of headaches wrapped up in a 15 minute photo essay. As I was told it is rare for sensors of this generation to die so dramatically, but you never know what could go wrong with a 25+ year old car. I HOPE that no one else has to go through this problem like I did, so with my take on a solution I hope it helps others who may encounter this issue in the future. For the TL;DR: 1) Sensor breaks. 2) Find a replacement GTT/GTS-T sensor. 3) Find a CNC machinist to have you cut it down to proper specs. 4) Reinstall then pray to the JDM gods.   Hope this guide/story helps anyone else encountering this problem!

    • perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML
    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...
