N1 Block Vs Stanard Block

[danoz]

hi guys i got a rb26 with a n1 block thats is getting full rebuilt with internals

cp pistons rods cams blah blah and so on. i have heard that the n1 block is lighter but weaker does any1 have any input as car will be tuned around 400-450 rwhp in my cefiro and used for street/drift use

does any1 no how much power the n1 block can handle as i dont want to go all out with my rebuild to have the block crack???? any comments would be great thanks

[Craved]

i thought the N1 has a higher Nikel content to help with thermal stress etc ... hence handle more power than the std block

Sorry....too much to type but this should save ya

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

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

The N1 Block also has thicker side walls by about 2-3mm.

If you are feeling extra rich you can go for a GT block which is stronger again then N1

You better be feeling extra extra extra rich because Nismo only made 300 and they are all gone...

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?

[GTR1993]

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.

Sainty Engineering, at Wentworthville in Sydney's west might build you a billet block for enough money.

but does it chirp 2nd?

haha, thats pretty impressive reading.

[T04GTR]

oh im sory. i didnt relise we were all making 1000hp and needed such blocks

[Duncan]

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?

[LBR33]

LOL............Billet is for sunday drivers, he needs a custom tungsten block

[maccattack]

Nissan sells N1 blocks - around $3000 - just ring them.

I picked one up from Nissan last year just by ringing the local parts division.

[Amaru]

Last year you could pick them up no problems. You cant do that anymore as production has stopped in Japan and there are none left in Australia, and very rare and expensive in Japan now.

I heard tomei has rb26 engine castings and can make their own
