stu I'd run the toyos or kumhos depending which is cheaper for bashing around the track. but sooner or later you will want to know "what is the best time this car can do", and the only way to find out is to put the best tyres on it. About 350 each instead of 500. Careful with second hand ones, they look cheap but can we well and truely rooted even if they still show tread depth (heat cycles kill them not wear) lets say the dunlop and bridgestone are a second quicker than the next best tyres (possible at some tracks).....imagine how frustrating it is to try and make up that second through power, suspensions settings, different driving lines etc when you could just bolt the right tyres on. Combined Touring Cars went from A048 control tyres to Kumho V70A and went a full second faster. Then control tyres were dropped, the front runners are buying new dunlops and bridgies, and going 1.5 to 2 seconds faster again. Improved Production still run A048 and despite far more mods being allowed (eg engines are free esp for non turbo cars) their quickest cars are slower than the fastest production cars.

try the A048 with relatively low hot pressures, 30-32. Different tyres react differently

is it a full moon or something? Time to settle down with all the silly carry on thanks kids....I thought I was in the drift section for a second

My opinion of relative performance and price of semi slicks: Dunlop DZ03 (expensive) Bridgestone Re55s (expensive, now) Yoko A050 (expensive) Kumho V70A (medium) Toyo 888 (medium) Pirelli P-Zero (v expensive) Yoko A048R (expensive) Just a guess on the yoko a050 I have not run them personally. they might be quicker than the re55 but its hard to tell because they are a softer compound. Also bridgestone are terrible in the wet with low tread, and the kumhos provide consistent grip well below the wear markers (ie they last a long time without dropping off). Yoko A048 are OK for first 3 laps but drop of really quickly, well before they wear out. I don't know anything about the 2nd tier tyres (falken azenis, kumho ku36, federal 595rs etc etc) except that you will loose at least a second or 2. ultimately if you want to win you need to buy new dz03s each time. anything else depends on how much you can compromise.

rb25 blocks have oil squirters???

looks like Greg set the second fastest time up there too. was talking to Ray Dean who did the regularity the other day and he said organisation and driving standards were fine

lol welcome back thread! for what it's worth my car was TERRIBLE! when it hit the cut...and fuel cut defender did the job perfectly

CAS is different on the r34 too. but no difference in the actual mechanicals

sorry but no way is a GPS receiver more accurate than a dorian. GPS is no quicker than 1/20th a second. Dorian reads 1/1000th GPS is no more accurate than 1m. Dorian reads to under 10cm As long as the dorian is mounted properly of course....if it moves relative to the car it will give an inaccurate result.

if you do buy the whole car you can always get a couple of hundred at simsmetal for it

I'm amazed there is one in the country. Pretty sure no importers have compliance for them so SEVS is out, they are post 1988 so you can't use that rule. So any car came in under either personal import or race use only. btw $36k is a spectacular price. I paid $5k for my march super turbo which is even more rare. sorry just read the ad properly. it is a personal import

whatever that was it was tiny. mine ate a washer once and it made waaay more damage

sounds very bad to me.....fuel is a rubbish lubriant, almost as bad as coolant but assuming you changed it, most of it was removed (no oil cooler?), and the problem was fixed that may not be it.....you don't have the oil that just came out of it?

haha I don't think I'll take running in tips from a sport where a 60 second engine life is considered good personally I start it, warm up the water, then take it for a hard drive a low but not no boost. revs up to about 5000 and as much load as possible without labouring it. 50klm then drop the oil. new mineral oil in then either 2-300klm of road driving (as above, medium revs, low boost, as much load as possible) or on a dyno 100klm. dyno is much more repeatable than having to deal with traffic/speed limits/road conditions. then tune it. drop the oil and race it. I've never had a problem with ring sealing (plenty of other problems lol)

ask for the price on a vipec I'm sure you'll get a response

just do a compression test!

2nd one is the alternator earth, you connect with a pissy little bolt into the threaded hole on the body of the alternator above the positive stud. don't get them the wrong way around it makes sparks when the engine starts

yeah for sure....and no doubt the most serious guys will have new tyres each round....if not the series is not competitive enough It was run and won on the weekend, plenty of skylines in the mix according to the results: http://www.natsoft.com.au/cgi-bin/results..../2010.SAN.S20.Y Sam Markov won in in his BMW, 1.16.6 JFK 2nd 1.16.8 Tony Avramides 4th 1.19.7 Michael Rice 6th 1.21.9 Jeff Beable (targa) 7th 1.22.8 Neil de Pau (Neil) 8th 1.23.5 David Tinworth 12th 1.24.8 Kevin Galvin 14th 1.25.1 Robert Marshall 15th 1.25.19 John Richardson 19th 1.26.8 Mark Hawkins (haw001) 20th 1.27.2 sorry not sure if the other guys are on the forum....but a great turn up from nissans/datsuns which were by far the most common make there. well done neil in a good run considering its the first time he's seen the track outside the xbox. And of course congrats to JFK and Sam who were absolute miles ahead and very competitive with each other. Also good to see Mark's car last the day as a test for targa in 4 weeks

have you still got the oil? get it checked for fuel that will tell you very quickly if that was the problem. i think its more likely there was another problem that showed itself with the sustained high revs - maybe a slight bend in the crank from the start? was it tunnel bored or checked for straightness on first assembly? or more likely just pinging up high smashing the rod bearing (it is #6 after all)

they are a great little car, amazing traction at the rear

lol. spray painting *looks* so easy at first doesn't it. I think I have a patience problem...

ahh......excellent idea! upsidedown 'shrooms!

car's still there....however Andrew has been abducted by aliens. I don't think he'd ever find out if I ran it at superlap for him

jeebus. 1.02.9

Yeah in qualifying (closest parallel to superlap) they run in the 29s. And this car has every right to be faster with the extra mods allowed. Most importantly of all they should have access to years of data about the track, compared to most other competitors who have only had a few practice days there, or none at all. Would be great to see local engineering stick it up the whole world My guess is that soft semis in the same width will not be any slower than dunlops control slick. Dunlop have no reason to make anything but a super safe, durable tyre when it is a control tyre.
