Hi there,

I trying to find some info on upgrading the sway bars in the R33 gts-t..

Has anyone actually upgraded their sway bars in a Skyline (and still has stock suspension)?

I don't really want to read what Whitline say, I want to here it from a skyline owner.. Do they really reduce body roll?

Are there any negatives about getting a sway bar upgraded (apart from more wear on tyres etc..).

Thanks for the advice.

Cheers

Rob

Hey Rob!

i just got that front strut brace from UAS, and well hate to be a picky barstard, but did nothing Rob, i find it was the same, it was actually hitting the top of my engine (the middle section)

Anyways, yeh i didn't really see a difference @ all,

Im intrested in knowing if anyone has had the lower ones done, if they have lower ones...

sway bar is different to a strut brace.

a strut brace stiffens up the suspension so you can corner faster and stay stable on the road.

Actually, it stiffens up the chassis.
sway bar is below the engine

can't remember what it does

The sway bar, also called an anti-roll bar, is designed to resist the body roll of the car during cornering. It basically helps stop weight transferring from the inside wheel to the outside wheel.

I've driven R33's with and without and i have to say that the selby's sway bars from whiteline that are on my car ROCK MY WORLD!!! others on this forum have them as well and by all accounts, they love them too.

Go to www.whiteline.com.au and check it out.

:P

Thanks for the reply's.

So that said, I want to upgrade my sway bar but do I just get the rear done or the front or both?

Also anyone know a good thickness to get?

Hey Donnie,

Hmm, what can I say take, the strut brace back if it made no difference. I certainly felt an improvement...

Cheers

Changed both front and rear on mine. I got the adjustable ones. Turn in is heaps better. Body roll on fast corners is reduced, and if I want to hang the back out, just apply power and a little turn of the wheel. Best mod on any car. I've done this on my WRX and my Daewoo. Go through twisty roads and HP means shit. I've left a few highly modded cars in the dust with the Daewoo. For GTS-T, change the front bar if you only want to do one. But for best results change both.

And just for the record, Strut braces (on top of the engine bay) only increases chassis rigidity. It doesn't stop bodyroll. That's the swaybars job.

It depends what the car is doing now, handling-wise.

Rule of thumb is that a bigger / heavier swaybar on the front fill increase understeer, while a bigger / heavier swaybar on the rear will increase oversteer.

It would really be worth your while to talk to a suspension expert about it all.

I've put the HD R32 GT-R rear bar on my R32 GTS4. I haven't noticed a great deal of difference, but then I haven't really tested it. And I also have Bilsteins and Kings springs all round, so it would be really difficult to judge the effect of the bar.

And just for the record, Strut braces (on top of the engine bay) only increases chassis rigidity. It doesn't stop bodyroll. That's the swaybars job.

Yes it's the swaybars job but I have to disagree with you in that they absolutely do reduce bodyroll. The struts are restricted in their forward/back movement by the brace which in turn reduces bodyroll. Whether that's what they're for is moot. They simply do do this.

:P

What ARE you on, 2rismo?

Body roll has nothing to do with forward / backward movement of the struts. During body roll, the struts either extend or compress, depending on which way the car is turning / rolling. The degree of roll is controlled by the stiffness of the spring and the stiffness of the swaybar. The presence (or absence) of a strut brace has no bearing on this, other than to reduce the twisting in the chassis because the different ends of the car are sprung differently.

ahhh...

i wish i was an ascii artist or could draw what i mean in smilies.

Say you're going round a left hand corner...okay?

the natural way for the body to roll, as you correctly state, is to the side. HOWEVER, it is foolish to say that there is NO longitudunal movement of the struts, (i.e. front of car to back and vice-versa).

Remeber that i said, "whether that's what they are for or not is moot."

Strut Tower Braces whether it is their primary function or not, help with bodyroll. Physical fact.

:P

the old strut brace debate, let me add my 2c.

I had a good quality front strut brace fitted with stock springs and shocks that were in good condition and it did make quite a noticable difference to handling when the car was pushed - most noticably the body roll, much more than I would have thought (this was with stock suspension, not lowered at all).

Also I have since had the car lowered and upgraded shocks - I am not sure if the difference would have been as noticable if the car was lowered first as this changes the centre of gravity

I have had the selbies (whiteline) swaybars fitted and they are great. Cost about $220 each from memory?

Sways are just another way to customize how your car handles... you dont NEED sways but they are a good tool. I have a 240SX and I utilize a stock SE front sway bar and a Suspension Tech. rear bar. This allowed me to neutralize the natural tendency of the car to dive when braking before the corner and entering it at high speeds. Then when throttle is applied its very easy to drift the rear end out if needed and feel the break-away point on the tires. The rear end will step out sideways faster but when your not under throttle the rear end wont load the outter tire as much and you will avoid inertia oversteer. Heres my suspension mods as of now...

Tein HA Damper Coilovers with 8/6 Custom Spring Rates

Tein Pillowball Upper Mounts

Tein Pillowball Tension Rods

Tein Rear Toe Arms - Pillowball

Cusco Rear Camber Links - Pillowball

Kazama Subframe Spacers - Aluminum

Cusco Rear Strut Tower Bar

Ebay Special Front Strut Tower Bar - Hell yeah! 20 bucks!

Suspension Techniques Front and Rear Sway Bars - Front Not Installed

Falken Azenis 215/45/16s

Only competition I have locally is my friends GC8 (2.5RS Subaru Impreza) that has the same mods basically. Tein HR Dampers and the works.

Other Mods I Plan:

Do-Luck Mid Chassis Support Bar

R33 GTR Wheels w/ Big Tires

Kazama Front Tension Rod Support Bar

Pillowball Lower Arms

Then my car will be good enough for the street. The chassis already is stiff enough that it doesnt flex at all... my wheels come off the ground on en-even pavement.

    • Hi everyone, I've found some free time to write up my "build thread" which is 10% 'build' and 90% fixing problems of a skyline that has endured a lifetime of abuse. I will start with the backstory & get everyone up to speed. Ever since I was just a teenager in high school I have had a spot in my heart for the shape of an R32 rivaled only by the look of an S13, my mates & I all having overly ambitious dreams as one does about having the sickest car in the school carpark. Unfortunately I started my journey of cars down the path of the Silvia and after spending years of putting up with the underwhelming SR20 life I dipped my toes into the 1J Toyota pool for a small moment until my true compass brought me back to that incomplete dream of an R32. At this point the trawl through marketplace, gumtree, carsales etc. starts looking Aus wide for an affordable example in the current economy which was extremely barebones compared to the good old days of sub 10k cars everywhere. Out of the handful of cars in the budget at the time I settled on a 1992 R32 GTS-T that was located in Adelaide. It had caught my eyes as it was similar price to the others on the east coast and had been RB25DET NEO converted and an open door respray in a custom colour based off TH1. It was also a stand out to me because it already had some NSW registration left which saved me the hassle of getting it on the road in my state. As for mods I was told it was pretty stock other than the motor swap, a nistune to run it, and an unknown fuel pump. My first mistake was trusting the seller blindly that the car was in good condition in all aspects and decided to purchase the car unseen other than some walkaround videos & pictures as the flights down there were very expensive at the time. The price of getting it transported to my door from Adelaide from Sydney was surprisingly cheaper than the flights at the time. I was told the few issues it apparently had was only 1 speaker not working, some cracked or missing trims, and it had been rear ended at some point but had been all professionally repaired (this is all foreshadowing at this point). I paid for the car, and then booked the interstate transport. Now at this point save your criticism as I already know how stupid I sound in hindsight, this was a major lapse of judgement and I accept the problems that followed. I spent the next 2 weeks in a crazed excitement knowing I am finally the owner of an R32 & that it was on its way. I started preparing as when negotiating with the seller I opted out of the Lenso wheels as they aren't really my style & I wanted a set of genuine wheels, and the bucket seats in the car as I am 6ft5 and not the skinniest guy so I had my predictions that I wouldn't fit in them anyway. Due to this the car was put on a set of R33 stockies and some average condition R33 seats that he had laying around. While I waited for the car to arrive I went and picked up a pair of R32 seats and some R32 GTR wheels to fit nicely on it once it had arrived. Being the first time I had done anything like this or had a car transported interstate I had no clue how the logistics of it were, I chose my work as the delivery address assuming it would arrive at some point in the middle of the day. You can imagine my surprise when I wake up to a call from the truck at 5:30am telling me his about 20 minutes away. When I tell you that was the fastest drive to work I have ever done, I managed to catch up to the truck before it even got there. Spent the hours before work taking in the car and living my first experience with one, I had never even been inside one so I spent some time getting familiar with the interior before doing the seat swap. Here is my first proper photo of it as the sun rose in the background. I also noticed it had the switch for the electronic front lip which was a pleasant surprised but sadly upon looking it didn't actually have the lip or the motors or even any wiring behind the switch. As I swapped the seats, the extremely questionable history of the car started to show itself starting with some really dodgy seatbelt buckles that had been extended for some reason with horrendous welds. This was followed by me noticing the drivers side front was quite bent up to which the owner then decided to let me know it had been hit in the front at the same time as the rear end. It also had a pretty leaky power steering rack and the pump was screaming for its life. By now I was a little on edge but I had to get to work for the day, I sent the car down to my mechanic to get the fluids changed and a general check over as I started to question what I had got myself into. I packed the GTR wheels into the car to get put on while it was there as I ran out of time which was a struggle because the handle to release the fuel door/boot was non-existent and just had the end of the cable tied to a bolt. It wasn't much of a surprise when I got a call saying that it looked like the fluids hadn't been done in quite some time. Although that didn't come as a shock, it did catch me off guard when I was told he couldn't open the boot which had the wheels in which I just had open not long before. Mission #1 was to squeeze through the back panel and open the boot from the latch while loaded with a set of wheels which to my amazement he pulled off after a bit of a struggle to reveal there was nothing holding the cable mechanism in place where it sits at the fuel cap. After that dilemma was solved the mechanic did an inspection over the car while on the hoist with nothing too interesting being found other than the expected crushed frame rails. It seems to have had some bilstein shocks installed at some point and judging by the AWD sump that has been sealed up I suspect the NEO is out of a stagea. By the time I got the car back and was ready to have my first drive home in it I was still excited but now quite anxious with the car already. First stop was to the servo to get a nice fresh tank of fuel as I had no idea how long it may have been sitting around for before I bought it. It sat quite nicely on the GTR stockies I must say. Now my drive home from work is short only being a 15-20 minute commute so the chances of anything going wrong is quite small right? WRONG. As I go over a speed bump only 100m from home I start to smell the dreaded smell of electrical burning and my lights drop out and shortly after the car dies. I am in extreme panic at this point thinking the car is going to burn down on its first drive before I have even had a chance to insure it. I move to the bonnet as quick as I can and lift it up, and as I go to grab the bonnet prop my brain is in such a frenzy that it takes me a second to realise my hand is being burnt to a crisp. This is where I notice that there is no plastic clip for the bonnet stay and when I have gone over the speed bump it has knocked the stay onto the positive terminal of the battery welding itself there. Levering it off with a nearby stick I sat there for a few minutes making sure nothing was going to burn down while waiting for a mate to come jump start me. My main stress was that I could've absolutely cooked the ECU or any other electrics. I was relieved when the car started fine with jumper leads on it but it would die as soon as the headlights were turned on so I carefully limped it home with no lights and decided it was a tomorrow task. You can see here where the stand sat on the positive terminal. Thankfully with a new battery the car behaved and seemed healthy. It was pretty smooth sailing for a little while getting to enjoy dailying the car. Interior wise it was pretty much as the seller described except for the the lack of working speakers, the digital controls had no power, and the headunit would randomly turn off & on. I installed a quick release I had laying around from an old car to help with getting in & out of the car and a nice momo wheel. I bought some oem side skirts to match the rear pods that were on the car already, who said a skyline can't be a practical parts mover. Test fit looks good! Found a good deal on a GTR wing & boot that I couldn't turn down. At this point the skyline was being too good to me and had to throw the spanner in the works again. First incident was as I was coming off the motorway and heard a bang and an awful grinding noise. As I pull over down a side street to investigate I notice my whole exhaust has basically fallen off and is dragging on the ground. After waiting around to let it cool to the touch I managed to get it back on its hangers. Thinking it was a weird 1-off instance I didn't think much of it until it happened to me again a few days later to which I see this time the middle hanger has snapped in half and the rear hangers have snapped at the welds. I manage to get the car in to a shop to get the hangers welded and while there I notice that my intercooler has broken its brackets and was being held up only by the piping. Quickly got that sorted and got some thicker brackets out of steel plate to support it all. Just when you thought at this point the car might give me a break, I fill the car up on my way home from the fabricators shop and after I pay I walk back to a good portion of my liquid gold on the floor. I just shrug it off at this point in exhaustion and call it a job for another day. The car had other plans for me though as the next morning on my commute to work, I am halfway there when I notice I am struggling to shift gears. I get lucky with a run of no red lights to work and find some time on my lunch break to investigate the problem. The slave wasn't leaking and the master still had fluid so I was left confused until I contorted myself under the dash and noticed the whole pedal moving loosely side to side when pushed in. Upon pulling it out of the car I found it to be multiple snapped spot welds on the clutch pedal bracket and the actual face of the pedal that sits against the firewall had snapped in half. I jerry rigged it with nuts & bolts at the spot welds but I will need to come back to this in the future and replace with one of the strengthened nismo brackets available. I then got to enjoy the car for another 2 months of cruising and dailying it, peep the obnoxious fireballs it would shoot every shift on the dodgy tune that was on there. On a sunday drive in that period of working car, I was on my way home on the motorway when I heard a slapping noise on my front left to which I pulled over to find my indicator had ejected itself from the car. Nothing a bit of tape can fix lol. I then bought some smoked indicators but after I realised I didn't like the look I found some damaged series 1 indicators. I repaired the tabs with some cut up cards and they looked good to me. My next venture was the hunt for some wheels, I test fit my mates Work Equip Spinning that were tiny 15" and I wasn't sold on the small wheel look. I ended up finding a killer deal on some Rays Volk Racing Group C in 17x8.5 & 17x9 that had been rebuilt many years ago and not ran on a car. I am still yet to get these on the car as they require some specific adapters and shank style lug nuts but I think they will look awesome. At this point my 2 months of reliability had ran out and on a cruise with some friends I suddenly lost the ability to shift gears again and thankfully could get it home by taking main roads and not having to stop. This time my master cylinder was bone dry and the culprit was the clutch slave that had decided to let go. It was a quick and fairly easy fix, but in my luck bad things always come in waves. Only a few weeks later I am on my way home from World Time Attack when the car completely shuts off while coasting down a hill, I try crank it while I still have momentum but no luck. Thinking I might have killed the fuel pump from running it low or maybe killed a CAS because the symptoms seemed to line up somewhat, I opt to get the car towed to a workshop to get fixed up on the Monday. When it gets there they get stuck into diagnosis and the CAS wasn't sending a signal to the ECU, and the fuel pump was also dead so it was comical for a small moment there. They replace the dead fuel pump when one of them notices some smoke coming from the passenger kick panel. Boy oh boy this is where it gets very bad and very expensive. I am not sure who wired the car when the NEO swap was done originally but I hope they never attempt auto electrical again as I am lucky that this handywork only managed to short and kill the ecu and engine loom and not do more damage. This is the point where you could say the 'build' started but not by choice. After some deliberation with my bank account I opted for a Haltech Elite 2500, RB terminated loom, and WB1. While I wish I stopped there and did the minimum of get the car running and leave it at that, I slipped into the rabbithole and decided I wanted to make the most of getting a retune and throw some bolt ons at it and see what it would do. I then threw together a bit of a mix n match build of marketplace deals starting with a GCG GTX3076R, a turbosmart FPR6, 980cc injectors, walbro 460, jackspanian ffp, throttle & fuel rail. At this point it was coming along nicely, the shop was making quick work of it and the bay was looking a lot nicer without the stock crossover intake. I also got them to replace the noisy centre bearing while it was off the road. Then we couldn't get an OEM CAS to talk to the haltech so ended up getting a PRP Street Trigger Kit for it.   While the car wasn't playing nice it decided to kill the stock alternator too so went with an LS1 alternator conversion kit. By now the car was pretty much done and ready to go but come tune day the car kept throwing the timing out every time it would warm up. Upon further investigation it seemed to be warping the PRP trigger bracket when the metal would get hot and expand which would cause the sensor to lose timing as it moves. Herman advised that they have seen the issue a few times now and don't know what the cause is. At this point I decided to switch to the PRP Pro kit with the crank trigger and considering the whole timing belt would have to come off I decided to get a new timing belt kit with water pump fitted. The car would now run fine with no issues and it was finally tune time. It ran up a healthy 275kw but ran out of boost due at 17psi to the rear housing being undersized. At this point the clutch also started slipping and due to it still being a weak RB20 box the tuner set it up to ramp from 8psi up to 17psi with the revs so that it wouldn't load up the clutch and box as hard. Car drives like a dream now. With the car back on the road I could return my focus to the smaller details, starting with getting a set of badges for the hood and quarters. I was struggling to drive with shoes on and I noticed that my accelerator pedal sits higher than my brake and clutch, if someone could confirm how it should sit that would be great. Next little changes was a killallwipers rear windscreen wiper delete, I also got some interior bits I was missing such as parcel shelf speaker covers, wiper trim cover, and boot floor and trims. Finally made it to a SAU NSW event which was awesome to cruise with a bunch of likeminded individuals. Another creature comfort I decided to look into was my lack of A/C. Since the Haltech got wired up the digital climate would power up now, and would blow but no cold air. First issue noticed was the lack of belt on the A/C compressor. After sorting that to no avail, it also had no A/C gas in it, but turns out the condenser has a huge leak. We are almost caught up on the story so far, but at the start of this month while coming into a driveway I heard a huge clunk in the front end to which I got out to witness whatever dodgy camber arms someone installed in this at some point decided to snap in half and I feel very lucky that it didn't happen at speed. Managed to get the car fixed the next day with some replacement GKtech arms. Next problem to address was the leaking gas tank from months ago. Checked the pump hanger seal first but that was fine, stuck my camera up after filling up to try scope out the leak which looked like the breather hose. Got the car up on a hoist prepared to drop the tank when I reached up to feel with my hand and I could feel that the hose clamp was missing and soon after felt that there was a gaping hole in the top of the hose. Replaced and tested and the car holds its liquid now and doesn't give me a fume headache whenever I drive it now. Finally have caught up and now onto fixing my latest issue which is the lack of dash light when driving at night, checked fuses first, then when searching I found the common problem of the headlight switch burning out but mine looks fine. Next test will be plugging a known working headlight switch into my car to tell if my switch is dead. Sorry for the long read but I wanted to be thorough, so if anyone made it this far I salute you soldier. Enjoy the rest of your day and I will keep this updated with issues I find/solve and any cool mods I can do inbetween. Merry Xmas!
    • can someone tell me what information a block number of 330680a on a rb25det engine specifies?
