Rb25Head Rb26Block

[FalahR33]

You know what get the hell outta my party....i know 30 block is bigger, i know 26 head is far way better. But i already have no way back now...ok? I spent good amount of money and if isnt of no use i'll buy another 26head and we got another engine...yeah it will be a brand new engine because the 26block has a very very wide variety of highly engineered parts down there from the biggest aftermarket engineering companies in the world that the 30 doesnt. Thats the whole main reason smart guy. Starting from tomie crankshafts to uprated pistons, their rings and everything...then my head will have tomie or hks camshafts and a whole new set of sensors from nissan to make the calculations just accurate...oh i also bought carbon fiber rocker cover and i dont wanna give that away...and a big turbo with the manifold, downpipe etc...so yeah i am a twat and next time do your retarded research right because bikes have reltively smaller engines and they are sooo many times faster than cars can ever be!

Not meaning to offend here..

But they were meaning the N1 block isn't worth buying over a normal rb26 block if applying your head..Or the 26 bottom being of any advantage. The cost far outweighs any gain ( there won't be ) over a 25 or 30 bottom end, which you can still put all your HIGH quality brand crank, pistons etc into.. Seems you are also money conscious, so forget about the N1 block, and spend the money elsewhere.. The block itself will not make the motor any better in your case.

Also standard rb30 crankshafts have produced over 1000hp, therefore not requiring aftermarket crankshafts, also the only reason someone would buy a tomei crank is if it were a stroker, which the rb30 does with it's capacity.... I'm not even going to list the aftermarket support for the whole RB series of engines, but there are plenty of big brand companies producing quality products = and superior to the Japanese product which will work with the 3l

The 3L block has its flaws. Yes they are ok to make HP but the 26 still does it better. If he has a Tomei stroker going in then he is better off with the N1 block anyway because it's ability to be further machined and still retaining strength. Then theres also the fact the Tomei crank will spin up faster due to its reduced weight, better counterweighted for the aftermarket rotating assembly and able to rev much higher without risk of crank flex or movement. When everyone else is changing gears at 8k, he will be flipping the bird while he hangs on at 10k

I would say let the guy do as he pleases, he's not doing anything wrong.

Thats true, but he won't be changing at 10k with hydro lifters. So a block that bolts up would seem a better option or a head that suits the chosen block over extra machine work to achieve the same thing... If he had a built head already be different story, but seems as though he is only into early stages of build..

Either way, yes it can be done at a cost, whether that cost is a smart or most efficient decision..
