Where the arrow is, there is a nozzle sorta thing. that leads to the actuator. This isnt how my turbo looks like atm, there is no hose connected.

what does that do? i have seen on some 33 turbos, that has been blocked off?

thanks..

that, my friend, is simply a nipple that lets air flow from the compressor to the wastegate

they are on r32 turbo's but not on r33 turbo's

that picture is a turbo from an r32... (it says 16v10... r33 turbo's say 45v1 or thereabouts)

on the r33 they have a nipple in the intercooler piping somewhere that goes to the wastegate instead

hope that helps,

yeh, ur right..i dun have it..when i checked again.

is tells the wastegate what the boost is so that the wastegate knows if it should open or not

i guess in a way, it could possibly be more accurate than having the 'nipple' on the cooler piping? because its directly from the turbo?

depends how you look at it...

at the turbo you get exactly the pressure of the intake at the turbo

after the intercooler, and you get it to measure exactly how much boost ets to the engine after the pressure loss of the intercooler...

i think the latter is more beneficial myself personally

so i drill a nipple on the turbo? :s..

think ill pass on that..btw rumour or not, the r32 wastegate actuator when fitted onto r33 turbo..does boost to 10psi without any boost cuts or spikes..

smooth and solid boost right through out the rev range

    • Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy. 
    • New [400]Z, they're available in manual and you don't have to worry about parts scarcity.

    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
    • Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
