No probs, I'll be getting a small digi tomorrow so I'll post up then. I have noticed the 33 doesn't have a magnetic sump plug just to collect those nasty bits as a warning. The good news is I have been told (by She Who Must Be Obeyed) to do a good job of the build this time...do everything.

Duncan, thanks for the update. It wasn't clear on the CAMS site. Roy, never too much, and I'm with you on that.

Latest update for the interested: Turns out I ran #3 big end and scored the journal lightly. The residue in the sump looks like gold dust! I started with the head off, checked the bores and popped the cams off - everything looking good - which can only mean bad! Torqueing the exhaust cam down I snapped a bolt that had an existing fine crack so a bit of hassle but better to find it now. Next the engine is supported and the cross member comes out so the sump can come off. Off with the big end caps and #3 is identifiable straight away as the problem but the others are getting close anyway and the crank journal is scored on #3. No choice now - needed a new engine stand so a 1500lb job for $110 will do from alltools Thommo. Pull the block out and put oil all over the floor of the garage (it's all mine tho so no landlord to p*** off) and off with the cradle and everything is sweet down there but....I have cracks showing in #1 and #5 pistons (stock 30000km 0.5mm OS) and a yucky looking deposit on the #2 bore low in the cylinder like water was sitting in the rings????? Well this bit I don't do so I will be off to a reco shop to get the journals freshened, pistons pressed off and GTR 8.5:1 jobbies fitted and clearances checked as well as new rings, bearings and basically everything else I can think of but I will still do the buildup myself. This site has been awesome though and I owe a coupla donations. Finding out that lower comp and stronger GTR pistons will fit @$120 each from the local Nissan dealer is wicked. I already have the good conrods (not the ones with the knob) so thanks to whoever posted that thread and a really cool mate who I have done a lot of favours for surprised me with an autometer oil pressure guage that matches my boost guage as a thanks and chrissy pres so no more low oil pressure.... He rocks and has a cool 180 with a new RB20 install so I am shaking at what that will do with the boost wound up. New front mount should be here soon and I'll get the dump of BATMBL soon and then my only dilemma is what computer to go for..... Any suggestions??? Prefer piggyback like the SAFC or the Greddy eManage.

So ultimately the finding is that Ingall is wrong and Skaife wears no blame for his part. Thankyou, Cretins Against Motor Sport (CAMS). I thinke the stewards need some time on track to stay current. Mind you Ingall was charged with bringing the sport into disrepute - really? A class that is so obviously a farce? Yes Roy, we need to see the end of large wings and reduce tyre size/adhesion. But also remain realistic as far as divergance from the stock motor car.

I have a couple of further points to make, but I didn't want to be too lengthy earlier. If speeding cameras always go into black spots and not "safe" roads then why should we not know about the locations and have them clearly signedas such? If so many people get fines does that mean we do not agree, as a voting majority, with the legislation as it stands or the rigidity of the upper limit? Does that then mean that the government is ignoring the will of the majority? Should it not be the subject of an education campaign and a referendum so we get Choice as a voting majority? Just something to chew over, and I don't agree with detectors. I do think the road angel (not a plug) is a good slap in the face for the traffic nazis, who hate it, because it just tells you where the approved camera sites are as you approach them because they are black spots, aren't they?

Funky I don't have the issue with the company doing the radar as long as they are spotlessly clean with the job they do. It is the legislators who say here is a hard ceiling on speed, against expert advice and extensive study, to generate revenue on the back of grief. It is the Police lackeyism, who should mandate training and education, not support 3kmh tolerances and inappropriate limits. I want to know who is in a position to advise as a neutral third party? In any other business or Government sector there would be charges of inappropriate behaviour and fraudulent behaviour to answer.

Oh come on. You can not seriously believe that they actually care whether you live or die on the roads? They prefer the carnage so it adds weight to their arguments that SPEED KILLS!!!! Sure it does, even the car rolling down a driveway at 3 kmh over a 1 year old, it is the speed that kills, but they'll call it a tragic accident. A stationary car parked will do bugger all. No Speed, no kill. Tell me how many accidents are actually fatal where speedING was the contributing factor. Any speed can kill. Current technology may protect you at speeds of less than 80 kmh in a frontal and 45 kmh side. That is explosive pretensioned seatbelts and airbags. Not present in three and two of my four cars but I still take my chances in traffic because I accept the risk. I have taken a personal interest in the technology and law behind this garbage and as a very proficient road user, never caused an accident and haven't had a fine in 10 years, I am disgusted how the little lambies believe everythig served up to them. Worked as an Ambo driver for a while and the Police attitudes sucked. Just as uneducated as the majority of the population who are happy to subsidise Bracks and Co to the tune of Hundreds of Millions of dollars every year on the basis of suspect technology. Imagine my wife's surprise when we drove through a mobile speed check displaying our road speed and as the only cars on the road it registered close to our road speed (indicated) then a few kays less then a few kays less again. "Who's car was that?" Just ours on the first and second sidelobes but it coulda been another car in another lane going a lot faster but not in the camera view (had there been a camera). Challenge everything. I'll be happy to distribute some literature if you want it. A basic tenent in most states of the US (where freedom reigns supreme) is the 85th percentile rule where at least 85% of the traffic is travelling at the appropriate speed for the section of road and they generally use engineers with educations to determine limits. Here it is concerned mum and dad, some plods, RAC reps and maybe even a church group rep. Where are the professionals? Who has the education and skillsets and technical mastery? Just how many drivers are getting fined? More than 7.5% would suggest speed trapping. Setting limits too low to extort money through fines. Statistically the other 7.5% would be under the true safe speed. I almost mowed a kid down in the burbs the other day because I was too busy checking my speedo at 45kmh instead of looking for the indicators that something is about to happen. Thank god for R33 brakes and my reaction time - he just ran out between the cars onto the road and would be just as dead at 45 as 50 or 60 (yeah I've picked a couple of those up and the drivers were shattered by the experience even though not their fault). I despise this government and anyone who supports their attitude to speed revenue raising without understanding the facts or undertaking to educating themselves and i am sorry i am taking it out on you. It's not personal and it is complicated. You cannot just one line it and think the problem is solved. Hope I can make it up sometime.

Once again you are getting to the crux of the discussion. The cooler air is good, but the volume of water to cool the air is a tradeoff that sees no benefit from the cooler, denser charge. It is the detonation suppression that is the real benefit in introducing water to the cylinders.

Warpspeed I like your explanation, saved me from digging through my archives although I would suggest that the nitrogen is not the only working fluid, even though it takes up some 70% of the atmosphere. This was the reason for oxygen injecting the Lynx 1.8 with stock exhaust and pod filter to achieve low 7 second 0-100 times. Also used an extra injector and water injection off a throttle switch to activate it all and activated it at over 3000rpm for a huge push from the little machine. Anyway, have to go look for some new pistons. Time to go to that forged piston thread after the bearings went west and scored #3 big end journal and cracked 2 pistons prior to the water injection.

The primary need is to atomise the water as fine as possible, and I use the Spraying systems nozzle as identified in the autospeed article for both applications. I have the intake spray after the intercooler in the line where the air velocity is higher so there is less chance the water might settle out to pool. Before the IC it could settle out as the velocities reduce, much like an oil catch can or dry sump, although I doubt it with the heat. It is on a rising pipe as well so any overspraying or activation when the engine is not running will have the water run down to the intercooler. Just worried about hydrostatic lock. It is really a worthy upgrade.

Merli the water spray into the induction limits detonation in the cylinder, not so much by cooling the air but a poorly understood phenomenon that needs more research. The water takes up enough space that it's cooling (compressing) effect is negated by that but it cleans the cylinder and suppresses the dets, and is therefore a good thing.

MY unit only cost $85 from Autospeed assembled + the watersprays

I also have a 4 pot NA and a NA V8 but they have their uses...just not on the race track.........

OK, almost science degrees aside because I only have a Mech Eng Degree and a Masters of Engineering, here is what I have found by using Autospeed's IC water spray controller on the stock IC with a high resolution high freq temp probe in the post IC airflow, Rigoli modded stock turbo and my home made boost controller @11psi. On a 35 degree Melbourne day I am maintaining charge temps 20 degrees below standard. Without the water spray the temps take forever to drop from over 57 deg to 40 deg but with it running with the fuzzy logic from two bimetallic temp elements it is a matter of 30-50 seconds to get to 28 deg or so down from 42-43. Now I haven't fully applied the 'scientific method' but I am pretty secure with my findings as a definite improvement over an air only IC. I also now run a throttle position induction water spray post IC and find that a positive step as well for suppressing detonation. My advice...you have the autospeed link, spend $150 and try it out and stop supposing. It works and works well. Maybe one day I will tell you about oxygen injecting my Lynx to a 7 sec 0-100 machine.

Seems to me the driving emotion is to have these bcos they are cool or throw more light. H4's for the 33 come in different colours and wattages so thats easy, and a lot cheaper. On the more light issue, well I used to rally, and big Cibie Oscar plus with 150W globes was the answer, but I wouldnt put them on a skyline. If you need more light then up your wattage on the high beams only and don't dazzle the oncoming traffic on low beam. That is almost as completely wank as the HSV and WRX owners with their foggies and worthy of a fine if the donut kings can unweld themselves from their patrol cars seats. Don't rice for the sake of it and blowing cash on crap, especially if it is going to cause discomfort and danger to other road users.

25 which controller do U have and what do they retail? I could use some of that!!!! That seems consistant with 'lines that you have to feed the power as they go soft at pull pedal when running the std computer. Anyone else experience this?

Had a seal went in my compressor once, real bad, and cracked 4 pistons and half filled the 'cooler with oil. What a pain. Stripping the 25 down again in the garage and leaving the block in this time so I have to make a bracket to suspend the block while the sump comes off and the big ends replaced.

Did anyone else talk to the old guy with the 33 4 door? got like 240rwkW. has had a real collection. Mutex knows a bit more info.....

I have too much in third and start to wheelspin on coarse road surface at 100kmh. Wheelspin in the wet also at 180 in 4th too if I floor it. Modified stock turbo from Rigoli but mostly stock with 0.5mm OS pistons. Dump pipe and IC are stock for now but 3" zorst and hi flow cat. Power comes on like a sledgehammer at 4000 so maybe thats why it does what it does and only at 11psi. Bit laggy though under 4000 and have trouble staying with stockers through the roundabouts out here. The straight bits inbetween make up for it and the handling but slow out of tight corners.

That was my Soarer. Pulling the bottom end down in the red barge as further diagnostics indicate a big end has gone. Not bad to get 120000 with 40000 running my numbers (~300kW) out of the RB25. Great day and nice to talk to a few people. Might meet at Thommo for the cruise but gotta get a leave pass.....

depends what your measure is....I can wheelspin fourth at 180kmh in the wet if I overdo the accelerator while other cars are even more serious, and having flogged a Z then got back into my 'line......not impressed. I imported this car myself and have rebuilt the engine myself when a comp seal let oil into the intake at high boost and done it all pretty cheap and it is pretty strong but still improvements will be required to get the track car I want. Z is comparatively a step back for Nissan except the 'line is still flagship model and a turbo option is still not dead because you can't just change the turbo on the Z, or wind up the boost. You have to spend a lot of money re-engineering for the power some of the guys on here are getting. The Z will apparently not get the 'dryer as it is not their flag machine. Ultimately it is a a 'nice' new car, but I have no professional respect for Nissan bringing that thing in and claiming it is a red hot sports car and dragging the masses into agreement with advertising and media lackeyism. There are media reps out there who have identified it is a flawed vehicle in the handling dept and I agree on some counts. I also believe it coulda been so much more or they should step up with the V35 'line and the turbo if it is produced to take on the local hacks BTW that was hardly smashed ........and without being there I could rudely suggest that maybe things didn't go your way, but that would be trolling I have done the drive comparo tho and I wouldn't spend that much (+$60K) on a car so underpowered and flawed

Given that it costs about $1500 AU to bring a skyline out to oz in a sealed container and that these guys don't convert to left hand drive I have one thing to say RIP OFF MERCHANTS!!!!!!! There is no way they are giving value to the sum of $15K US and are milking the market due to monopoly. Even early on (I was one of the early oz importers) there were only bigger prices like $7K AU to comply a R32 GTR. I'd go without first I'm afraid for that extortion. You could fully strip and rebuild a 'line for $15K US.

I will, having thrashed one. There are plenty of cool kick arse nissans in Oz but they are not 350Z's. Stock R33GTSt doesn't quite handle as well but at that cost with the engine so breathless at high rpm I would expect more, much more. Understeers a bit but very go-kart in feel. The V35 'line will suffer the same engine dissappointment but word is that it will eventually get a turbo while the Z won't. Skyline is still the top of the heap for Nissan. That will not stop the easy conversions tho and the wrecking yards will be picked clean by Z owners wanting cred for their gutless wonders. Apparently the Euro model was found too harsh on the roads so they retuned the suspension and it actually handles. Japanese were so impressed that now all 350's will get the new suspension settings. Never pays to get the first release of a new model.

AND WHERE THE HELL ARE THE ROUND TAILIGHTS RENAULT??????? sorry for shouting. anyone see the Speed article on the Z where they found the V35GT turbo?? lookin' good for a factory model.

Sure I'd prefer the 350....not I'll post pics of the V35 GT when the site starts to work for me...meanwhile surf to www.nissan.co.jp and translte with babelfish from altavista
