Hi everyone,

I'm new to the site but i've always loved my Skylines, I bought an XR6 Turbo back in december because i wanted a Turbo car but i needed a 4 door for work (or so i thought).

Don't get me wrong i love my T but i'm strongly considering selling it and buying a 98-2000 R34 GT-T 5 speed.

Is there anything i should be looking out for or problems that may arrise when buying a skyline. For example i bought a 5 speed which is the worst box the XR T's come with but i didn't know at the time. I wanna try and avoid these things if possible this time.

Thanks in advance

Dillon

You can't go wrong with a late model R34 man.

the 5MT is one of the strongest you'll find on a road car.

Id say the only down side will be the stock turbo on the R34.

if you leae the car stock, it's all good.

but to make it lag free, nissan have used all lightweight shit like a type of plastic for the compressor wheel and ceramic for the exhaust wheel.

which is all good and gives the car a lag free driving experience.

how ever, increase the boost to around 12psi and they tend to let go soon enough.

apart from that, at those boost levels, the ECU runs in to rich/retard issues and you need an aftermarket computer or some sort of AFM signal bending piggy back like SAFC.

A hiflow, ecu, injectors and fuel pump and you'll be good for over 220rwkw before the AFM maxes out.

Z32 AFm and you'll be on your way over 250rwkw.

I'm sure the XR6T produces these numbers easily, but the R34 will be about 200kg lighter.

I'm sure you won't regret getting an R34 GTT

Yeah but the xr6 is making those figures at the flywheel, not the treads like you're talking about

The T's about 190rwkw stock. I wanna have the R34 at about 300rwkw enought to still torch most of my xr6 turbo mates. So what your saying is that the 5 speed box wont have any dramas with this power? I will get a heavy duty clutch and mabey flywheel so this will help too.

would be good if you could put that engine in the r34, even a 33.

you have a nice car man. i wouldnt change it, but you cant go wrong with a jap car :dry:

Yeah there a great car with so much potential for big power, but the gearbox is giving me the shits and it's about 6k to replace and i've always wanted a R34.

EDIT: Nothing wrong with RB engines, i use to have a VL :ermm:

lol probably 10 k to get 300rwk out of a r34 gtt. ecu, turbo, injectors, exhaust, fmic, bigger fuel pump. it never ends man.

dont forget brakes and suspension. you dont wanna end up smacking into something

Sh*t that much. Mabey this ain't such a good idea.

For the T i'd only need valve springs, bigger injectors, fuel pump, custom flash tune, demuf, 2nd cai and mabey a bigger cooler.

An r34 with gt-rs turbo, injectors, fuel pump, ecu, exhaust, cooler will make around 260rwkW, which is heaps and boost will be available early (about $5000 if you do the labour yourself). Don't forget all the change you'll have left over after selling the xrt :dry: .

Just wanna throw an element of realism into the mix...

There are a few "laws" i guess you could call them, that come into play the more power you have...

A RWD car with heaps of power is more likely to just spin its wheels unless you have great tires and suspension setup.

Also, to get a lot of power with skylines you generally need a bigger turbo, and the bigger the power target, the bigger the turbo required....and the bigger the turbo, the more lag you have. This only pushes your usable power further up into the rev range and will make the car less responsive and not really the speed machine you're after.

There is a happy medium though, and you can have an extremely responsive and extremely fast skyline that is also reliable and relatively comfortable at the same time.

XR6T's are great cars, all things considered, but being heavy they're not _that_ quick when stock. They do have great potential though, just a pity about the trouble you're having with the manual box. I can say that Nissan gearboxes have a name for reliability and strength. Even the auto boxes will handle 240-260rwkw pretty nicely :w00t:

I'd recommend a R34 with minor mods to begin with, exhaust, safc (or other ecu/piggyback), boost controller. For an extra bit of oomph, a GCG hiflow (or other) turbo, fuel pump, nismo FPR/bigger injectors, upgraded AFM, bigger cooler, brakes (important at this stage), and 16psi or thereabouts and you'll have a very fast skyline.

One thing you'll notice is that the RB25 will rev a lot higher than the XR will and faster as well, not that you need me to tell you. The characteristics of either car are at opposite ends of the scale. The XR6T is a low-revving torque monster with a relatively small turbo for its size, whereas the skyline will rev its guts out and IMO feel more involving and excited...(ie. not saying its more exciting to drive, although it may well be...but the car will feel like it just wants to go...fast)

you'll notice my bias...but this is a skyline forum. I actually drive a stagea, which is about the same weight as your XR6 and with my current mods would probably give it a run for its money too. But being a wagon its not the ideal sports car you're looking for...and I dont intend to make it one :) thats what skylines are for :)

G'day mate,

i'd suggest keeping a close eye on the for sale section. Your bound to have a R34 come up forsale at some time already making 300wkw. Grab that, all the work is done and money has been spent. There are always quite a few high power cars forsale going cheap (for what they are).

There a number of big dollar R32 GTR bargains at the moment.

      R32 Skyline Interior Door Light Issue

      By DominusUniversi · Posted

      I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.

      WGNC34 - floor mats

      By Marek · Posted

      Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted too.

      How To: "Refabricate" a Stagea 260RS/R33 GTR Speedo Sensor

      By aznriptide859 · Posted

      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!
