200000km old stocker is gonna be stronger than a new n1 block.

a 200000km old n1 block would be very strong

it comes down to weathering of the block/metal.

it worked for the 1400hp 1.5litre bmw f1 turbo engines :domokun:

if you can find a virgin bore old 32 block its gonna be plenty strong.

give advan performance a call. hes done some research on the issue i believe

or id just like to get my hands on a group A block :)

Apparantly 2-5 unused blocks have found their way on to the market in Sydney in the past few weeks with a going price of $7000ish. Just what I have heard from a couple of people though, unsure how true it is if you actually went to buy one.

for 7000 i would be looking into a custom made block, place in adelaide is looking into (or made) billit SR blocks and billit SR inlet manifolds, blocks were going to be around 5000 i think.

How much stronger would something like that be?

I am no expert but would be greatly stronger as you can add material where you like, run no water galleries if its a drag car, more studs in bottom end caps/girdle. Tie in the end caps fromt he side of the block as well. As its custom you dont work around things that the factory had to like cost etc. I have seen a 1UZ (i think was in zoom) custom billit block as they were splitting the stock blocks.

Also off the top of my head there was a custom 4 cylinder motor made for a drag can in the USA, custom billit block running nitro, It was new set up as he was using motec and going to run in some sports compact class (cant rember details hopefully someone can post a link to the video) something like 2000 hp is i remember correctly.

that is a link to the 1UZ block but im not a member of lextreme to view...

that link for for the nitro 4 cylinder, 4000 hp, it says the block of alloy is over 1000 dollars by its self, im not sure how much machining would be if it would be under 7000. They have no coolant or oil drain back so for anything other then drag for a few seconds its no good.

I was just saying for 7000 for a block it opens up a few more options.

but does it chirp 2nd?

haha, thats pretty impressive reading.

Just Jap have a Group A block for sale. I'm pretty sure you won't find a brand new n1 block in Australia.

But who breaks a standard block unless you are making 11tybillion kw or bored it out over 87mm?

    • 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. 
    • Just planning to have the wiring neat and hide as much as possible.
    • 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?
