Ok, I started the same sort of thread on the SDU web site but, lets face it this forum is MUCH better. OBJECTIVE : Do mid 13's(possibly lower) all day with the standard ecu, intercooler and turbo re

i got a 13.981 at calder last night... could have probably done better, but happy for a first real strip run. Set my 235/45 tyres to 16psi and I have pineapples on the back - seem to have less traction probs than some of the other gts-t boys who also ran.

What mods do you have??

a few :P its not really "stockish" though as the thread indicates...ah well..

S-AFC, cold air intake, dump pipe, hi-flow CAT, HKS Super Dragger II cat-back, blitz pod, HKS FMIC, ProfecB EBC, heavy duty clutch, pineapples, zeal coilovers, falken 235/45R17.. stock ECU, stock Turbo @ 13psi

i think some heat buildup and trying a bit too hard could have effected my later runs.. i'm gonna wrap some of my piping soonish to maybe fix that for next time.

thanx :( other runs were around mid-14 at higher MPH (~100).

Its all in the takeoff, which i'm sure you know, but its definitely what I found out on friday. The difference between a 14 sec run and a 13 second run is all in a good takeoff.

Easier just to just post the timesheet with the 60', etc.

If I can get that a bit lower (which I think I can next time), I think I may be able to get about a 13.6 or something with a perfect launch and my current mods. I'll be happy with that until I one day I upgrade the turbo, ecu and maybe a couple of other things which should push me into the 12's. 12's for a daily driver that is RWD would be pretty nice I reckon :(

anyway, enough about me.. back to general discussion

yeah.. other runs were worse launches, but better shifting after that, resulting in higher top speed of around 101mph

If i can pull both off in the one run i'll get somewhere around the mid-13 i think as well.. tyre pressure could have been a bit low @ 16psi for street tyres??

I ran 14.370 @ 98.79, 60' 2.407 with a pod (no cai) and a 3" cat back zorst. I believe that 60' time could come down a few tenths with a bit of practice (I only had 3 runs on the day).

I just dont get it. predator666 you've got some decent mods I'm guessing they'd be around $2k rrp? Surely to goodness your $2k mods are more than 0.3sec better than my $400 mods? It looks like you can launch it better than I can also.

A question for all: How much did you spend (and on what), and what affect did it have on your times???

Most of the stuff came on my car.. but if u added them up prolly $6000-$7000 or so :P read back a page for the full list. 0.3 is a reasonable difference.. and 1 second is a massive difference in terms of what you need to do to your car most of the time.

That run i felt like a pretty perfect launch, and i took it a lot more easy on the gear changes afterwards. Maybe i backed off right at the end? (no idea). Anyway, its all in the timesheet up above, i'm no expert, and i don't remember every single detail! I only had about 4 runs.. next time i go, i'll hopefully have some more runs, and hopefully get a better time as a result of the practise.

Waming up your tyres with a burnout is good for show, but not really going to help you on street tyres.

I ran at eastern creek again last night and got a 13.102 @ 108.46 mph, killing my old time of 13.7 @ 105. I was much happier. My 60ft this time was much better, of 2.114 over 2.365.

I walked away grinning from ear to ear (I was hoping for a 13.4) :) :) .

I have standard internals, injectors and fuel pump. I am running a custom plenum, XF trottle body, FMIC, EMS management, high flowed turbo (metal wheels, no bb centre), running 17psi boost, exhaust, etc.. The tyres are 255/35R18 Fulda street tyres let down to 20psi.

Here is a pic of my engine bay,

They are close but still handling it. We have looked at them closely on the Dyno, but they are still upto the task at the moment. I am looking at a bigger turbo at the moment, so I will have to do something about the fuel system soon.

      Yet another RB Neo misfiring thread after reading all the others.

      Good tips, will get on those tomorrow. When doing the maintenance I did move a few of those connectors around, and things that are old tend to not like moving around. (Like me).

      Don't try it. It will be shit. Better chance of damaging the engine than gaining any knowledge about the old one. Maybe, but unlikely, especially if the O2 sensor is working. You can use NissDataScan to look at the stock ECU.   Cleaning the AFM is seldom necessary and seldom helps. The R35 coil & loom conversion should eliminate dud coils or plugs. But as you still have misses - look to the plug where the coil loom connects to the engine loom, and the CAS plug. Need quality connections there. Also look to injector plugs. And the AFM plug while you're at it. Also look to whether your injectors are clean and flowing evenly. Get them out and onto a testbench.

      Good to know, I feel like I am in for a rollercoaster ride that looks like a sine wave.

      Yet another RB Neo misfiring thread after reading all the others.

      Hey folks. I've been lurking and browsing the forum for a while, since I got into my head that I wanted a skyline. Having purchased an overpriced completely stock GTT, (only "mods" it has is HKS pod filter and catback) now that it became legal in the US, it was all glorious and sututu noises here and there. But then I wanted to do things right and went to do basic maintenance. After all the fluids, filters done, I did the spark plugs, that's when the problems started.. First the car started spluttering at around 4.5k RPM. Which I gapped down the new plugs and that solved the sputter there, but the car now always misfires at idle with pops when lifting off and shifting 2nd to 3rd. Similar to the issues in this recent thread. I've been banging my head against the wall, reading the threads here and trying suggestions for a couple months now, so decided to start this one to explain exactly what I tried and what is going on. The symptoms of the issue: Idle and low revs misfiring intermittently. You can hear the exhaust tone change and the shakes on the shifter knob. It happens frequently, but doesn't seem to have a rhythm to it. Pops when backing off throttle. It pops and or burbles almost feels like it spits fire when it pops. (Happens mostly in 3rd gear at around 2k RPM). When under load and after 6k RPM, it also pops when shifting from 2nd to 3rd. There's a ticking noise at around 2k RPM in 2nd gear going downhill, seems unrelated though but I am out of educated and downright dumb guesses. Not noticeable lack of power when putting the car into load. The attempted diagnosis and solutions: Unplugging coils when the car is running This did nothing to change the idling and tone shift for every cylinder. Checking the exhaust headers with thermometer They all are within what I'd say it is margin of error of the laser thermometer New spark plugs Tossed two new sets, copper, iridium and using the old ones, still misfiring, even re gapped to 0.8mm, still same thing. MAF cleaned with the "specific" spray cleaner No changes in the issues what so ever. Brand new loom and r35 coil conversion (was going to add the r35 coils anyway) car runs arguably better, still misfires, but seems like does less frequently. Placebo? Code 21 now being thrown, thanks nissan gods. Removed the CAS to check the shaft for play or anything. CAS seems all fine, nothing that indicates any issue, visually speaking. Things to attempted next: Ordered a new MAF (chinesium from Amazon, to be able to return regardless of result). Fuel with proper gas, maybe it is this California water that they sell as gas that is to blame? Plugin the link ECU and check the info using the built in base map. Go back to BMW and eat my rob bearing breakfast without milky oil mixture.   Do any of you have experienced anything like this or have any suggestion?
