White 35 and I have just returned from the Twilight Track Day put on by the circuit club. What a great event. 6 x 20 minute sessions after work including night driving. We were both using stock wheels and rather used road tyres.

I managed to crank out a 1:46:04 and White 35 did a 1:46:68. Not bad for stock wheels and tyres. Cant wait to set some times with slicks.

Can highly recommend this format to anyone looking for a midweek speed fix.

It was good to meet you guys last night also.

Would have preferred to have been at the twighlight track session however the Drags were interesting and different. Ran a consistent 11.9 for the 1/4.

12.03 for the first run

then 11.92, 11.94, 11.93. (Terminal speeds were also consistent at 194km/h (121mph), 193.8km/h on the Performance Box)

Consistent runs, but the start was a little ordinary with wheel spin due to the water they were putting down, the car could only manage a 0 - 100 in 4.1, where as the best I have recorded is 3.8.

09GTR ran the Dunlops and I ran the Bridgestones - both of them absolutely fried...

We are both moving to Volk RE30's and Hoosier R6 slicks in the next month.

Both have AP rotors slotted 09, J Hook on mine and carbotek 12's.

Do you have harnesses Duncan? or a Race seat? i was being thrown around the car in the standard seats...

Jeff could to meet you to dude - we all gotta hook up for the next EC day - i'll email you the stuff we talked about at the servo. Gotta get those quarter mile times down to low 11's...

I was expecting a mid 11, basically 11.6 or there abouts as a stock car, but the launch just not happening.

I look forward to catching up with you guys also and starting on these mods.

Gibbo, it was good to meet you albeit briefly. I did an 11.7 stock. The difference will definitely be the launch. You really do have to "sidestep" the brake as the revs start to slow towards 3300rpm (while boost is still building). To get 3300 rpm I find I have to stomp on the loud pedal as if it were a cockroach heading for my gym bag! I also found that my car got quicker as the night got longer for three reasons: 1)temperatures got lower 2)fuel load got lighter 3) track got grippier.

In fact I've got to the stage on the strip where I know more or less what my time will be based on the launch alone. If you hear a small chirp of the tyres as you release the brake, you're on.

I'm going to go back to the drags when the weather gets cooler, put in some octane booster, dial up 20 pounds and have a crack at a mid ten. White 35 is also keen to come, we'll let you know when we are going.

The Twilight was a great night but I do have some questions of White 35. How can a car putting out identical power (detuned for track), with front and rear sway bars, with a driver that weighs 75 pounds with his clothes on, get done by the red version without sway bars and a driver weighing 220 pounds?

I suppose its true....red ones really are faster!

Well done guys, sounds like a lot of fun. Any more feedback on tyres, brakes? what tyres were you running?

I had the Carbotech 12's at the start of the night, but by the end of the night I just had backing plates!! Seriously, coming into turn one well into the 200's, in the dark, mashing the brakes and having a flurry of bright orange sparks flying over my car, wind-tunnel style, might have looked good, but it didnt feel so good! Suffice to say my front rotors are looking a bit soiled!

That said the braking performance of the carbotechs is special. I wouldn't go back to the MX72s for track use.

I am running the standard seat with a harness (just a four point). Looking to fit a race seat soon though.

      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.
