Pro Gtr Rb Billet Block

[chairman]

I asked nitto if they will make bigger than 3.2l crank, no chance

[jangles]

More people than Nitto make cranks.

94mm cranks are produced already, couple that with a potential 90mm bore and its 3588cc.

[jangles]

From the pics though, you couldn't do a 90mm bore unless you made it open deck

Might need a drop down menu for the 20 k gearbox you'll need to handle the twist of something like that...

You need that with a 2.8 apparently, so it should be expected.

can the factory head be fitted to this billet block or billet head as well ?

The head pictured is a factory head.

[jangles]

Max bore is 88mm anyway on this block. That's why I said it's a theoretical shame.

88mm is still 3430cc though.

3.2l with 88mm bore whats that equal to

[GTRNUR]

90mm x 88mm bore = 3285cc.

I'd have liked to have seen a billet alloy cylinder block that used Nikasil plated cylinders, instead of a iron cylinder. Basically what Porsche did with 928 engine. It would have made it a far more streetable engine, and would have allowed them to stretch the bore to 90mm as well. There are companies in Australia doing Nikasil re-plating for some motorbike cylinders, so it would have been possible to do without going over-seas.

Based on their posted R&D photo's on their facebook page, I think this is targeted more to the methanol burning 1500+hp drag racing croud.

I agree with the drag racing thing. I'd assume replacing sleeves or buying block without sleeves could be done down the track

Anyone can bore a liner, not everyone can relplate a bore. It's a question of practicality.

[GTRPSI]

Would be a similar situation as with Honda S2000 bores, once worn people turn to liners, not many workshops in Aus can bore the factory cylinders and finsh them (polished) correctly as the OEM finish.

Even so with all the mucking around to fit liners, S2000 owners dont flinch to go liners and bore as needed once the factory bores are toast.

hnggggggggg

[Shoota_77]

It's just a big fuggin lump of awesomeness!!

I'd probably be relocating a belt tensioner a bit higher up the block to reduce belt slap a bit.

im just raping images from there FB page.... but why not.

it seems it fits all the stock oil setup but this one will become dry sump.



so solid
