Ok, if there was ANY chance of a car coming off on that corner the tractor shouldn't have been deployed. "Sorry MR and MRS Bianchi, we could of waited until the safety car had the field under control, but that would of taken an extra 15 mins, and like, annoyed the fans" Seriously. Anyway, it's been a good chat, but I've really got no more to say, except Forza Jules.

Ok, So if the driver gets it wrong (fairly high chance) and there is no tractor, hits wall, walks away with a sore thumb. Gets it wrong with a tractor, loses his head. The driver should not have to worry about running into things like tractors, or marshals. Anyway, keen for Russia. F1 and Bathurst in the same weekend. Score!

Oh boy. Ok, It did fail, because there was an incident. Whoever decided it was a "low likelihood risk" got it wrong. Just to clarify, there are hazards (a hazard can cause harm or adverse effects). And the "risk" is the chance or probability you'll be affected by the hazard. The hazard in this instance was to send the tractor outside the barrier. The risk was the chance someone would hit it. Given that most of the time drivers do not slow down enough for double waved yellows + worsening conditions + tractor in a perilous spot + marshals present + contact with said tractor could easily result in death, I personally would not be comfortable sending it out, knowing, what would (did) happen if a F1 car hit it. You do raise some valid points though, motorsport is dangerous, but things can happen, caused by an incorrect (unsafe?) choices that make it un neccessarily dangerous. I believe this was one of those times. Anyway, its obvious we both have different views on the subject, and thats ok. In short. Yes motorsport is dangerous We dont need to make it more dangerous by sending large rigid, objects into the potential path of errant racecars.

Well, the risk management failed this time, and resulted in a driver being seriously injured. The people making the decision to recover this car using the JCB should have identified the hazards, some of which being, worsening conditions, tractor on the outside of a fast turn (!) where another car has previously come off. There is no way that tractor should have been sent out without a safety car. Yes i'd rather "shut down the whole race track for 10-15 minutes for that" than see anyone suffer the same fate as jules. If it would have been a marshal, we would have been reading about a death. Setting a delta time for yellow sector still leaves a risk present, what if the driver chooses not to stick to delta time, then comes off? would have been the same result. The only way to eliminate the risk is to not have the tractor where it can be hit. The marshals on the track in germany was another one that had me cringing. All of these near misses are forgotten about while they are just that, a near miss. Doing nothing about a near miss results in an actual incident, sooner or later. Anyway, just my opinion, and I sincerely hope Jules recovers and can lead a somewhat normal life.

Coming from a workplace with a zero harm safety standpoint (steelmaking industry) I can't believe we are still sending marshals and recovery vehicles onto the track with cars doing almost race speed. (Japan and germany this year) Lets face it, the double waved yellows, no one slows down anywhere near enough, all thats needed is the driver showing he has "lifted". Maybe thats not the rule, but it never gets enforced. Tracks are designed (generally) with safety in mind (barrier placement, tire stacks etc) in the event of a driver leaving the course. By placing a recovery tractor on the track side of the barrier is absolutely unacceptable. The only reason Jules has the injury he does is the fact that tractor was there. Take the tractor out of the equation, he would of hit the barrier, or sutils car, both which would of not been any where near the severity of what happened. I think I'll be a minority here, but IMO no marshall, or recovery vehicle should be on the track untill the whole field is under the control of a safety car. You can't put people's lives at risk like that, its ludicrous. Its a bloody joke, and the FIA need to tighten up their regulations on this sort of thing.

Can't go past a hypergear highflow, get your neo turbo highflowed, and you'll go close to 300rwkw on 98 fuel. Laurel looks cool btw

That looks unreal. Good work.

Do you have a blow off valve? plumback or vent to atmosphere?

Dudes. Did some general maintenance on the cefiro. New front wheel bearings (S14/15 type). Mine were cactus, and looking around, cheapest I could find were Just jap at $179 each. Pricey cause you need the whole hub, can't just press in/out the old bearings Turns out CBC bearings make a replacement, using NTN bearings, for $212 for the pair. Score. Have to re use wheel studs, which I was going to do anyway, (nismo 90mm studs) Pretty easy job. Although the drivers side bearing inner race was pretty stuck on, had to grind a flat and chisle it off. Also, did a service, plugs, oil, etc. Car was tuned on a 0.7 mm plug gap. New plugs were 0.8mm, thought, she'll be right, well. No not really, misfired like crazy on high boost. Borrowed a mates set of splitfires to diagnose, and it fixed the issue. So bought a set of splitfire, geez, the car has never ran so smooth! It drove ok before, but the difference with new coil packs is a blow out. They also seem to of fixed the typical RB idle pops. Its is unbelievably smooth now. Highly reccommend new coil packs! Also, here are some pics of my JJR belmouth dump that I modifed. My turbo (highflowed OP6) had been machined out and it didnt really fit well with the flange on the dump pipe. I read its common to die grind the step (which was almost 10mm in my case!) but didnt really like that. So took the opertunity to chop it up, ensure its not going to cause a restriction. Can see the white on the flange how much needs taken off, and the "hump" straight after turbo Attempt at die grinding New section welded New flange, still had some cleaning up to do in this pic. Anyway, seems to work well, and its still holding up, no evidence of exhaust leaks, even though there is not much surface area at the bottom of the flange. Had a drift day at wakefeild with the new setup, trickier to drive with the added lag, but much quicker. No real issue, except for me not plugging the cas in all the way, wouldnt rev above 3k for a bit. lol. Still keen to get back to unigroup for a play with the cam gears. Also, with the new coil packs might be able to squeez in a bit more boost. Cheers.

Check crank angle sensor, it might be cactus or not plugged in all the way. I've had that happen to me before

So you want 400hp at the engine? Buy a hypergear R34 op6 highflow. That's the easiest turbo upgrade (bolts up to all of the standard stuff). Get whatever ecu your local tuner recommends. Sounds like you have the exhaust and intercooler sorted. Fuel pump (walbro, bosch, gtr, or z32, whatever is easy to source local), GTR injectors, z32 afm. On a RB20, you DO NOT need cams, or even cam gears, oil pump upgrade, oil cooler (unless your going mental on a track), or most of the other things you've mentioned. I have almost what i've mentioned here, make 324hp at the wheels (almost 400 at motor), thrash it on the track (its a drift/street car) and have no issues. My RB20 has 180 000 km. Keep the oil level up and regular changes. Tuner that knows what he's doing, and it will last a while. Anyway, happy researching.

Im with shannons too. Both my cefiro and wifes 300zxtt. And we were both under 30 when we took out the insurance, they were the best price by far.

I use castrol vmx 80 with my current rb25 gearbox. Car is used as a daily, and also drifting. I change it at a 12 month service, which would be 3-6 track days and about 20 thousand km. Box was second hand when I bought it, almost 3 years ago. Previous cefiro had a stuffed second gear syncro, i.e wouldnt go it gear over 3500 rpm, changed to redline lightweight shockproof and it near on fixed my issue, couldnt notice the syncro issue driving normally. On the flip side, had a mate (still rb25 gearbox) with a notchy second gear syncro, he changed to redline LWSP and it made the issue worse. So I dunno, I run the cheap stuff, and if (when) my box has issues i'll try a redline oil again.

Yeah i've found the same with the 3 aftermarket turbo installs i've done on stock manifolds. Checked my current OP6 highflow (so stock rear housing flange entry point) and it was very close to the exhaust manifold opening. The first one I did years ago was a KKR 430. It was shocking, honestly had a close to 10mm step.

So you mean granny shifting, not double clutching like you should, isn't real? Dang. But on topic, I'd change the return point for the bov. Im actually in the process of putting a stock bov on my cefiro, and Mark (unigroup) said to be carefull how I plumb it in, and pretty much said point it directly at the turbo. Broken record I know, but its worth a shot yes? As for you fuel economy, are you thrashing it everywhere? cause 250km to a tank is shocking. I've got the 02 turned off, doesnt affect the on boost performance and I easliy get 400 -450km to a tank

Has Yavus or Mark been for a drive in it? Surely with a "5 second delay in power on a down shift" they'd be able to at least give some suggestions. I had my car tuned there, no issues, but thought it was a bit strange they didnt take it for a road drive after the tune. Every other tuner i've used has did a quick check on the road. Saying that, my car has been ok. I also run with the 02 sensor turned off. (issue on the dyno, kept stalling when turned on) and get 10l per 100km on a cruise. (240rwkw RB20). When you downshift are you rev matching? or just letting the clutch out? does it make a difference to the hesitation?

Buddy Club P1's 2 sets, 1st set, 17x9 +17 all round 5 x114.5 pcd 2 have 205 50 17 potenza's about 60% 2 have dead skidders These rims have been spray canned gunmetal, One wheel also has some rash and a small crack on the inside, still holds air fine. These are a reasonably rare size. $1000 Neg. 2nd Set 17x 9 +27 5x114.5 pcd 2 have rotalla's 225 45 17 about 50% 2 have goodyear 235 45 17 almost full tread depth, but camber worn, These haven't been resprayed as far as I can tell, and look a bit better condition than the other set. Although they do still have some small marks, see pics. $1000 neg Located between Nowra and Wollongong. Prices are negotiable. Lowballs are ok as long as you dont get your panties in a knot when I tell you to GTFO. Will swap/trade for other rims, Something with dish, no smaller than 17x9. Happy to trade all 8 rims for a decent set of 4. Will not split sets, if you want 2 of each buy them all, and sell the ones you dont want on. Cheers

How much camber you running to fit those on the rear? Ive got a 17 x9 +17 and its a bit mexican, got sick of wearing out half a tire, so running 0.5 degree neg. Anyways, this is your laurel thread, keen to see what you think of how it drives with the SR.

Sweet cars man!

Not normally a fan of the SR but I like this! More info on the cefiro?

Thanks guys, will source a stocker bov, give it a go. Oh and FYI cefiro's were bov less from factory, but yeah, 10psi is low boost i guess

So, I currently do not run a bov of any kind. My setup, RB20, hypergear op6 highflow, usual supporting mods. Nistune. 240rwkw. With a fair smack of lag, lol. In past non-bov equiped cars, i've had the zu tututu/ compressor chop/ dose noise. When fitted with a bov, obviously the noise goes away, but difference in performance, or boost drop off between gears felt negligible. (as what most things I've read/searched) Current setup however, feels a bit different. If I get it on boost (>12psi) then lift to change gears, I dont tend to get the compressor chop, just one big choof, almost like an atmo bov. Also notice a fair drop off between gears. So afaik, the 'dose' noise is intake air coming out though the turbo, afm, etc slowing the turbo down (but not completely stopping it) One big choof would potentially mean the turbo is stopping?(or slowing down much more) Also, being a standard size core style turbo, would assume inertia would be rather low, compared to a much larger turbo. Do you guys, in this instance think a bov would assist in getting it back on boost after a gearchange? Cheers

Chasing a stock bov and recirc pipework from a RB20DET. Pickup prefered nowra/wollongong/south sydney. Cheers

Also pm'd!

Had no idea the thread was going to go like this, just wondered how a F/S thread for a turbo would be 9 pages long! Twas a good read.
