Keep in mind that if you are buying your Teins new, then they offer an incredilbe range of springs, from the sort of spring rates you would expect of a race car (we've all heard the stories... Teins are rock hard) to spring rates more suitable for road.

Tein HA are height adjustable (and rebound only??? i think) and if the car is never going to see track work, do you really need such a susp setup for the road.

If your stock shocks are in good nick (R34 id imagine so). id suggest some King/Selbys lowered springs that are only a slight increase in spring rate over OE. Your OE shocks will still work well with them and spend the money left over on sway bars and some new bushes if needed.

I suggest for a start you should leave the oem suspension and install...adjustable caster rods, and get adjustable camber at least at the front....

Even eith the oem suspension This will arguably improve the feel of the car and the handling by a greater margin than aftermarket springs and shocks without these other mods....especially if the oem stuff is still pretty new and working properly...if it is shagged then different story...

Food for thought....

What do you mean by OK camber? It may be ok, but not optimal for excellent handling?

I meant being able to adjust the camber to say Neg 2 degrees or so caster out to neg 9 or so ....gives the front of your car a stable predictable feeling and also increases the grip and turnin...

I agree, adjustable sway bar should be included in there. Prolly quite a bit cheaper than adjustable camber arms...upper or lower...very good bang for buck too...

I guess the point I was trying to make was that people imediatly go for springs and shocks which, dont get me wrong, improve the handling. There are however other alternative routes to upgrade suspension which IMHO offer better bang for buck and a better platform to later upgrade springs and shocks, wheels and tyres etc...

Anyway, blah blah blah...nothing everybody hasn't heard before...

Oops, perhaps a typo there? Neg caster?

I have 1.5deg neg camber with the the car lowered 30mm - that is what I meant by ok, from my understanding, it is only when you start dropping the ride hieght much over 30mm that camber starts to drift too far. Besides, if you upgrade your swaybar, doesnt this reduec the need (to a degree) for neg camber as it reduces body roll and therefore a change in the geometry during cornering. I also found a front strut brace helped in this are too.

I managed to get 7.5deg pos caster with poly bushes, and at 200 fitted, its alot cheaper than fitting adjustable rods, but I as they say 'you cant have too much caster':)

Yes...neg caster may not induce desireable handling characteristics hahaha...

On a 32 gtst I am of the opinion that there is almost no such thing as too much camber...within reason of course...I have run 3.5 with success...track yes....but if you are a spirited driver and like driving mountain rds quickly then I dont think 2-2.5 is unreasonable....

I am guessing though with standard suspension, camber may be around .5 or so?? and more neg would improve handling by a lot...

I should qualify a little too....I dont have hicas any more which means I need more grip in the front for a neutral feel relative to a car with hicas...

You can buy second hand adjustable caster rods for 250 or so....not too expensive.

I think we need to be mindful too that a roadcar often does not have the level of tyre grip to make use of nil body roll and an overly stiff suspension setup.....It can make a car quite skaty etc...

But overall I agree with what you say on the whole, there are a number of ways to approach suspension mods, depending on cash and what you want to end up with....

Cheers, Hope this is helping cre4tion?? Oh I have Tein HA and I dont find them to be too hard....They are hard but they are also very compliant, they do seem to soak up bumps quite well, they certainly do not crash at all.

Hi CR34TION, have you read the article on the R33 GTST on the Whiteline site? All the same settings worked fine on the 2 X R34 GTT's we have set up. The HPI Project R34 GTT also has the same set up and Ben raves about it.

I my opinion the Japanese are not very good at shock absorber technology, particularly the subtleties of achieving a balance in damping, ride control and handling. The leaders in this field have always been the Europeans. So I would recommend Bilsteins or Konis. Shop around, you may pick up a lightly used set for a good price.

Hope that helps some more

Cr34tion...I believe if you took your car on the track you would shave many seconds off your time with a few suspension mods...to get the same time from pure power mods would require significant increase in power....If you do a few of the things listed here to your car I gaurantee you will swear you are driving a different car....good luck with the research.

i found some Bilstein shocks and springs for my GTT but they are located in Sydney and I'm in Melbourne. Anyone know of if these are any good.. they are supposed to lower the car 2inches... is that too much as I wouldn't know cos mine is currently not stock.

cheers

Hi CR34TION, the standard centre of wheel to guard measurements are 380 mm front and 370 mm rear. Don't go any lower than 350 / 340 mm. Rear camber goes to shit, not enough travel to soak up bumps, rear roll centre is screwed, drive shaft angle soaks up power and bump steer becomes an issue on the front under brakes.

Bilsteins are good, depending on spring rate (around 350 on the front and 200 on the rear is OK). Billies have circlip retainers for the spring seats, so you can have extra grooves cut in the damper bodies and set the height where you want it.

Hope that helps.

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
