stock standard suspension under inflated - you wear both edges. less wear in the middle because the tyre bows upwards. over inflated - wears the centre of the tread

Seems that different cars use their tyres differently. I ran 32psi F/R in mine (R33 w/ std rims) and got shoulder wear both inner and outer, so I've bumped it for a while to compensate. Then again, I'm no grandma on the street so I might be using my edges more

interesting.. would love to know what's going on there!

After doing some reading, the only time a timing light reads double is when you have a "delay" timing light and you are using it on an engine with waste spark. I think the way those work, is that you set the timing on the timing gun and then rotate your distributor/crank angle sensor until the 0 mark on the pulley lines up with the notch. With a waste spark system, the spark plug is firing at TDC but also at BDC (minus however many degrees you have) but since there are 2 sparks per cycle, the timing light thinks your RPM is twice as high so its calculation for the delay is wrong. With a simple timing light that just triggers when it gets a pulse and has no delay/timing setting on it, you should be fine. I don't believe the stock R33 ECU uses waste spark, but an aftermarket system might.

He probably didn't unplug the plug on the throttle position sensor. As I have said earlier in the thread, the ECU uses timing to control the idle speed. So if you leave the TPS plugged in your timing WILL be all over the place. This is NORMAL. If your TPS is unplugged and the timing is still everywhere, and it's DEFINITELY not your timing light, then you have a problem.

If you're using the pads in your daily street driving, don't even bother with DS2500s as they need heat to work properly so you'll have very ordinary brakes when cold. I was recommended against them in my daily. I haven't had any fade problems with DS2000's (Formulas) and they work fine when cold. Stock power, stock rims etc so if you are modified you might run out of brakes a bit easier.

you've run out of boost juice. seriously though, could be an air leak, or problem with the wastegate getting stuck open or something.

depends on your area. I have driven past 5 servos in a row (Mobil, BP, Caltex etc) and NONE of them had 98RON. However, some servos seem to be able to get it. I think if you're higher up the food chain you get it, if you aren't then stiff shit. At first the shortage was only on mondays and tuesdays (cheapest days of the week, no coincidence I'm sure..) but now some of the smaller servos are permanently out.

I have also found many companies in the auto industry are shithouse when you contact them via email. IMO they shouldn't have an email address if they're not going to use it, but once you know the phone is better you don't bother emailing..

worth tuning an NA car? it's not even worth driving one.... ok ok.. some of us haven't earned our boost wings yet. I'm glad my first car was a charade i probably would have killed myself in anything quicker

on the freeway? you're getting gyped. Mine does 12L/100km around the city, best effort on the freeway is 9.3L/100km. small price to pay for getting there in luxury I say

that looks awesome. would be so much fun.

toluene is safe but it also burns more slowly, so it's good for raising octane but mostly for the safety aspect. the slow burn side of things makes your engine less efficient at making power (98 RON would give you more power than 95RON + toluene to bring it up to 98).

not according to their website - the only option is using a Z32 ECU and modifying your wiring loom.

my timing gun does double blinks, so the marks seem to jump all over the place. one way around it is to buy a short spark plug lead from an auto store, and put it on the #1 spark plug and plug the other end into your coil pack, you can then put the timing light around the actual plug lead and then it works fine. i then found out that if i put the pickup loop only half around the white wire on the ignition pack, that it works properly. so now I just do that have not heard of it reading double the actual timing, that sounds very strange to me. the timing light has no concept of timing, it simply strobes when the spark fires on #1 cylinder. so i can't think of a reason why it would fire at 30 deg instead of 15deg, unless you forgot to unplug your TPS (in which case the timing would be jumping around anyway, because the ECU uses timing to control the idle speed).

no, your base timing must be checked with a timing light. info meters, consult etc assume that your base timing is set correctly. there is a timing mark on the front of the engine, to the right of centre. it's basically just a notch, and you line that notch up with the marks on the pulley (which you can see once the timing light is correctly hooked up). see pic (arrow pointing towards timing notch, mine is painted white from the factory)

love the way my standard skyline handles. would consider pulling hicas fuse to see what it was like without but i'm not removing the whole thing.

nistune doesn't work with the R33 ECUs, which is a shame as I quite liked the idea of ~$400 for being able to make minor tweaks.

ah so this is where the debrief is good day, some nice cars there. shame about the guy who rolled, i was considering going out again but felt a bit so-so.. then that happened and i went "yeah... i'm gonna call it a day". had fun, but cornering speed pathetic with standard rims and tyres! need sway bars too heh. i'll whore my fav pic of the day in this thread too:

well that was a fun day, saw some interesting cars and good to see the skyline contingent was well represented despite losing numbers to wakefield today there's nothing quite like the sound of a race prepped RB26 on boost....

fark i'm happy with that!! thanks for the compliment Chris not bad for a stocker hey!! here are my piccies from saturday:

great day to get out and have some fun, bloody slippery in the morning (or does the back end of a skyline just experience some sort of mythical attraction for the edge of the track ) but the rain stopped mid-morning and it dried out. I finally got a couple of decent "grip" runs in around 2/2:30 and was happier with my line towards the end. No idea about times, if anyone has them fill me in No spins, but some rather interesting moments heading into the first corner. Great day though, thanks to frogman for posting details and good to see everyone

the shire - god's country, as long as you're a dropkick car thief.

will that pass scrutineering? "where's your extinguisher?" "oh, it's in chris's car next to his.." yeah i've been meaning to make up a bracket for ages.

lap dash eh... *strokes chin* spoiled for choice on easter weekend! i'd have to mount the fire extinguisher tho.. at the moment it's beside the emergency jack in my boot... lol.
