"RB30 me not have RB30"
yeah it was a little bit like that!!!!! the guy from Queensland transport knew straight away it wasn't a 2 litre, from memory its about the fifth time i have been pulled over since the conversion(in about 18 months). The other times the officers couldn't find the engine numbers, and i would hardly admit it was the wrong engine if they didn't have the numbers as proof.
-
I got pulled over and was unlucky enough to have my engine numbers taken down by queensland transport. Now I need a mod plate for my RB25/30 conversion, and because its a hybrid the engine it must pass a IM240 (for a 1992 car) as part of the cert process.
Who is the closest to Brisbane who does this test?
Also anyone with advice, who has mod plate for a 25/30, it would be much appreciated.

I think you should see small bubbles coming through the radiator(with radiator cap removed) when you repeatedly crank an engine with a blown head gasket. Is this true, maybe im wrong?
EDIT: just thought about it and this is a trick used in darwin where some cars have themostats removed. ie probably wont work if thermostat is closed.
also i recently had a radiator leak and the first radiator pressure test conducted by a workshop that specializes in radiator repair *apparently* held pressure even though coolant had literally drained from the stationary car. I told them to do it again and then they found it had a crack. They never charged me for the test and I took my radiator elsewhere to be fixed.

Alot of ozzies are rev heads so here has got to be a big audience out there if a decent local show was made, but when you so blatantly copy TGUK and you only have one hundreth the budget its bound to come out looking like a poor copy of the real thing.
I think maybe we should just be happy with some of the lower budget grassroots style coverage of local motorsport and car modifying scene created by real enthusiasts.
Couldn t Sau help TGA out with a feature on some oz skylines, Im sure there is plenty of people on here who would love to have a person with the IQ of a goldfish attempt to drift their pride and joy into a tree while complaining about the lack of new car smell and excessive value for money of buying an imported car.

I have done a very cheap RB30/25neo conversion on my 32 gtst around 300rwhp @7000 internal gate small turbo i think this setup suits 2wd. Personally with 4wd i would probably stick with a RB26 as more tracton offered by 4wd copes with a steeper power curve better. The RB30 with 4wd could feel a bit soft in top end of rev range with a small turbo and if you go big with the turbo you would have to rev the engine hard(not good on long stoke, especially with standard rods).
I am not an xpert on engine building but you kind of get the idea trying to rev such a long stroke motor hard is a bit of a engineering challenge that stretches the RB engines oil system to its limit. Not saying it cant be done just that engne internals will be pricey and oil system will require attn if previous posts on this forum are right. Also check posts by sydneykid regarding oil restrictor size modifications to prevent excess/starvation oil in the head.
Two small issues with my build were clutch master had to be moved because it hits the inlet manifold, also a standard 25 cross over top inlet manifold wont fit under 32 bonnet, i had to use modified fibreglass bonnet because of height of engine, at the very least some reinforcing will need to be removed from stock bonnet. Depending on our gearbox speedo sender and tailshaft may need modifying.
Just my 2c
Edit: tidied up BBcode for you mate, IPB tried to turn the power figure above into an email link because of the @ symbol lol - Revhead

..not only was he pussyfooting the GT Ph3 he goes on to say it's "re-inforced the legend" I thought the legend was shattered. He said the car has trecherous handling on the limit and then the Stig took it around in 1.22min...that's barely quicker than the Proton Satria...and the knob who spent $750K on a souped up XY Fairmont, needs brain surgery.
If i wanted to spend that kind of money on a nostalgic performance/super car that could rarely be driven and never left un-attended (unless locked in a high security fortress), I 'd be buying a Ferrari F40!
I had exactly the same feeling watching that segment, you get the feeling these old codgers with too much cash are making mountains out of molehills when they spend 500,000+ on an original 'aussie muscle car'that feature 351 cubic inches of boat anchor style performance. Then last weekend i went and watched the shannons sponsered muscle car series at QR and they answer became clear...... if you love old touring cars that feature a 8 cylinder soundtrack and you have that much dosh you would be cazy not to just buy a old race car and get some real bang for your bucks at the track.
Dunno about the F40, maybe a winfield GTR for me.

I know Martin Donnon applied. We would have made a good team.....oh well. I will just have
fun with my own cars.
Martin donnon would have rocked.
As it is TGA is an epic fail for one reason THE PRESENTERS ARE MUPPETS.
I cant watch it, its too painful. I can imagine TGA playing during the scene out of clockwork orange where the guy has his eyelids held open and is forced to watch all sorts of atrosities in an attempt to break his will to live.

I dont have a FC but i am curious about how you know you lost 200hp. Is it by seat-o-pants-o-meter or a new dyno run has been performed which states your engine now making less power with no signs of damage and same configuration of parts, same AF ratio, same ignition and full boost. If its now only making 200rwhp should be pretty noticable driving it!!!!.
Also it should not take long to work out where the drama is if its sitting on a dyno. Sorry im not helping but this is a unusual post.

which city - pickups?
otherwise nice wheels GL with the sale.

oh and btw.. u dont lose a fixed amount of power.. its a percentage.
every single engineer knows this.. are u one?? i would say not.. am i?? most definately
also.. power is just torque with rpm... if rpm climbs higher than torque drops.. power rises
i noticed it drops off extremely quick up the top thou.. not even stock turbos do that.. whats the deal there??
100% agree, the fixed loss drivetrain myth is SO ANNOYING. I beleive the principals of angular (rotational)accelleration are quite straight forward, applying more force to a rotating body will increase losses incurred in the conservation of angular momentum.
-
Thanks bill and baron, i think there is alot of people like myself with (dodgy) street setups that could get burned at the sprints, already lost a RB20 in darwin at hidden valley (38 ambient) because of slight overboosting for 5 laps. Not going that way with my RB25/30.
-
True. But then again people fall in love with their cars and in the modified car world its hard to be different and unique. If you have the cash, why not? I sure as hell would love to.
But then if you were to think about it from a calm and rational point of view, then yeah, you probably would get a GTR!
Dont fall in love with a car, normal people *GIRLFRIENDS* find it hard to understand why you just spend 20 grand on your car to make the engine bigger.

lets put it this way.. jap cars look more expensive then holdens, like my 95 model skyline looks better then the vz commodores costing 3 grand extra.!
i think you will find the particular jap models your talking about would have been alot more expensive than local 4 doors of the era if they had been sold here new. More expensive cars always look better than ones that cost half as much.
eg AUS new skyline GTR in 89-90 was 100k when a local Commodore SS Group A was about 50k so Im guessing if you could have brought a GTST new in australia in 95 it would have been more expensive than a similar mid spec commodore.
Also you have to remember australian car import prices are artificially inflated by import tarrifs and the SEVS scheme which protects australian manufacturers like holden and ford from competition from second hand imports by artificially raising the landed complied price, in NZ which has no import tarrifs there is very few holdens or fords on the road and almost all cars are 2nd hand imports from japan. If you could just buy a car in japan and import it to australia with no complience costs, there would be alot less 10-15yo holdens and fords being driven by australians.
Another thing is that import cars in australia are primarily two door sports coupes like Skyline, sylvia, rx7 and supra. There is plenty of cheap jap 4 doors which arent allowed in australia like nissan primeras, mitsibishi lancer GSRs, mazda familias, honda vigor and even toyota altezza which is already sold here as lexus IS

back to back runs on the dyno give you a better idea of improvement when its possible.
gonna ditch my SAFCII and get a AP FC and Z32 soon will try an get a comparison.

The input of energy required by a change of state from liquid to vapor at constant temperature is called the latent heat of vaporization. When a liquid undergoes a change to vapor state at normal boiling point the temperature of the liquid will not rise beyond the temperature of the boiling point.
The specific latent heat of vaporization is the amount of heat required to convert unit mass of a liquid into the vapor without a change in temperature.

Latent heat of evaporation at atmospheric pressure.

nice table dude , dont know if my thoughts are relivant but would methanol still vapourise at high pressure.
as pressure in plenum rises (presumably to 2-3bar)the evaporation temp of fuel should rise too if you dont get high enough for fuel vapourisation temp in the (pressurised)intake the latent heat absorbtion during vapourization wouldn t happen.

primary safety should be for everyone not just enthusiasts, problem is that manufacturers create products primarily for economic gain. Who cares if your car folds up like an aluminium can when it is in a nose to tail( more money for them when you replace it ) when common sense says build a car that would have never have had a problem pulling up in the first place. As consumers we should vote with our feet when cars are designed and marketed as crumpling behemoths with 20 airbags that can protect even the stupidest drivers from themselves.
I was driving a hire VE commodore the other day they have massive A pillars to accommodate the airbags in them. Never mind it cuts down your range of vision at intersections, classic secondary safety over primary, who needs to see whats coming down the road i have multiple airbags!!!!
I really think in cases like this the secondary saftey is there to help market and sell the car and actually makes the car harder to fix after an accident. More right offs equals more profits when the right offs are replaced.
-
I agree crumple zones are good - but the pictre of the ford pickup still demonstrates how much work went into secondary or passive safety, versus the distinct lack of work which goes into active or primary ability of the vehicle to avoid the crash.
The argument that people in a better handling and stopping vehicle will just drive faster and closer to other vehicles and therefore still have accidents would imply that it doesnt matter how safe a car is people are trying to crash despite the efforts of automotive engineers. If you are one of these people i suggest you stop replying to this forum and go and crash your car hard enough to negate the inherant protection engineered into your car.
-
Personally i agree its a good idea but like everyone is saying just understand what you are trying do is tricky at best and
will cost a bit more per horsepower than the turbo
in my eperience a stock looking engine will fly under the radar most times, the old 'thats how they come in japan' officer may even work for a centrifugal blower.....maybe.....positive displacement would definitly be easier.
as long as you dont have *extra fuel pumps in the boot
*a after market ECU in the glovebox or in plain view
*blow of valve or engine bling(pink cam covers/polished everything)
*missing cat/sooty rear bar
*turbo timer running when pulled up
*pod filter/jumbo intercooler (if you can avoid it)
*excessive gauges
you dont have to do what the others do, but this is the sort of thing you need either heaps of money and no reguard for how its spent or a vast knowledge of the principles and practicle application of them, not to mention the gear, time and contacts required to undertake something like this.

its due to oppupent saftey crumple zones.
its there to cushion the impact not because there made crap.....
Go run into a wall chest first with just a t-shirt on and see wht it feels like....then do the same thing with a pillow wrapped rounds your chest and tell me the difference
I think you may be missing the point mate! cars wth pillows wrapped round them(crumple zones) to protect mentally deficient american drivers are an example of ramping up secondary safety, the old ambulance at the bottom of the cliff. Designers should make cars wth better primary safety ie fit better tyres, brakes and cut down unnecessary weight while also lowering centre of gravity.
The photo appears to show the nissan is made of stronger matrerials, i think this may be a little misleading as you quite rightly point out. My point is the nissan engineers designed the tray to be tuf which it clearly is, while the ford engineers could have designed a car with better brakes that didnt weigh two tonnes, instead of systematically creating consumer demand for bigger and flashier 'PICKUPTRUCKS' then trying to cocoon the occupants in crumple zones.
PS i know new small cars have crumple zones too, and i may regret these coments if i ever end up sharing my front seat with a RB30.

just thought id relate my holden experience
i had a 93 VP HSV Senator had about 100,000-150,000 on it and in two years i put about another 100,000+ more on it. 80k to work and 80k home every day. I should mention it did alot of k's well above the speed limit in out of the way country QLD.
the motor didnt break *gasp* but very thing else did.
2x auto trannys
engine seals
cracked 17" standard rim (just cracked by itself)
Aircon lost gas
Steering rack & steering pump
shocks
terrible front tyre wear
multiple batteries
fuel pump
ignition dramas- cheap leads and plugs previous owner.
so i guess what im saying is i punished this car and found the ancillerary systems were bad but the motor and its managment seemed pretty solid although 165kw out of a 5L V8 is not a highly stressed engine. also i did keep oil and water fresh.

Webber is known to be a good qaulifier i was shocked that vettel could out qaulify him with only one lap in each session.
As for race stratigy i think RBR may have been trying to use webber as a rear gunner putting him infront of the brawns in case the track dryed and vettel needed a buffer.....only a thought.

Update - the metal frame on the trans tunnel side of the drivers seat that conects the seatback to the recliner hinge broke.
so i pulled it out at work and got it TIG welded up.
Anyone heard of this happening before?

or you could go the cheaper option with 2 vice grips on the steering shaft.......dont ask how i know that.
