Sort of off topic but it depends what you use the car for. I was talking to my engineer about this and he said the RTA generally don't like them on the road because they increase the chance of injury to the occupants (ie striking the roll cage) in the majority of accidents (collisions). Racing however is a different situation.

I second that.

Its screwed into the dump pipe just after the turbo - its a cylindrical thing about the size of a C cell battery

I would think the fittings and braided lines shown in that pic would be $500ish (retail), maybe more.

Sorry, VSI15 is the correct document - disregard my first post people.

I think there was a thread on PF that a Falcon one works which is about half the price and twice as easy to find - I will search it out.

lukevl, RX Engineering gave me the price of $100 cleaned, flow tested and serviced or $165 new.

On all the speed cameras (I have seen anyway) in NSW you can see the three lines that are cut into the road quite easily at normal travelling speed. In some cases on crappy roads its more noticable because the patch of tar has been replaced where the sensors are.

The conclusion: The article isn't really as interesting as it sounds. I'm not convinced the tests mean much in the real tho world because they didn't test the performance of the coolers as heat exchangers.

I got my RB20 one from NISPARES, about $70 I think.

Whats the best stuff to use as gasket when replacing an RB20 sump. The original stuff was a grey rubbery compound. Cheers, Tim

There is a PFC for the 32 gtst, Apexi's racing division (AP Engineering) modify a standard unit to suit. You can get them reasonably easy thruough places like greenline, hikari etc.

Contact an engineering signatory and ask them. They will be able to tell you what can and can't be done legally. VSI 02 contains the list of signatories. http://www.rta.nsw.gov.au/registration/dow...cinfor_dl1.html Also an excerpt from VSI 06 Please post whatever you find out.

Umm, as cheap as possible, like $5 each Realistically I will consider anything under $1,000 and my interest will increase as the price goes down. A pair was recently advertised for $800 in the for sale thread. Regardless of what I am prepared to pay, the real question is what do you want for them?

oops, forgot there was a wanted forum here.

After some GTR front seats in good nick. Please email ([email protected]), PM or reply here if you can help. Cheers, Tim

In a perfect world yes. I would expect the designers specify components that are oversized to allow for things like wear/fouling etc. How much each item is oversized is a anyones guess. Also, I suspect the specs of components like injectors are influenced by things like "standard" tooling so they are cheaper for mass production. eg why develop the tooling to make a special injector with a 0.2467mm hole in the end when you have tooling to produce injectors with 0.25mm holes.

This is my understanding - it may not be correct. An injector is basically a hole that is open or closed. The rate at which fuel passes through this hole is governed by the pressure differential either side of the hole (ie higher DP = more flow, lower DP = less flow). The amount of fuel entering the engine is controlled by the length of time the injector is open (ie higher Dt = more fuel, lower Dt = less fuel). The ECU controls the length of time the injector is open and the fuel regulator controls the pressure differential. In a turbo car the regulator raises the fuel pressure with boost so the DP across the injectors is constant. Any excess fuel is returned back to the tank. A fuel pump has a curve which relates its flow and pressure. Typically as pressure increases flow decreases. An engine will requires a certain max flow at a certain max pressure. The pressure is set by the reg and the pump is designed to meet this duty. If you start increasing power, the fuel flow and pressure requirement from the engine changes. If the pump cannot meet the flow requirement the fuel pressure drops, less fuel is injected and the engine leans out - which is sometimes fatal.

Well since I haven't been pulled over, maybe I am doing something right ...or maybe the cops here are just a bit more relaxed.

On the other hand tho - a lack of brain cells can also result in illegal mods. I bet cops and auto engineers would have some pretty good stories about downright stupid and dangerous mods people have tried. My theory is that if you don't put yourself in the position to be harrassed by the cops (ie dont act like a tosser on the roads and dont hang out with people acting like tossers) then your chances of being pulled over are minimal. Also if you are civil to the cop and can demostrate that the mod is safe, legal and engineered (ie you have a copy of the certificate in the car) then you are in a lot better position to go free than someone who has a bad attitude. I havent got to try this theory out yet tho 'cos i've never been pulled over.
