The Ultimate Rb.

[r33_racer]

or one better, nano tube carbon steel. That would be the ultimate.

Titanium is great, but its not the ultimate.

[N1GTR]

There is an RB being built at the moment that will be a first in the world!

Cant say too much but what i can say that it has been engineered and built here in Australia.

But if had a billion dollars i would have the bottom end made from titanium

You dont need a billion to have a Ti bottom end but you do need a lot

Ti rods are simple enough to get (with enough money haha). I know one guy who wants Ti pistons, thats going to cost him. Id hate to know what a Ti crank costs and even then how effective it would be. The scary thing is, he's serious

[N1GTR]

Noel you big old banana bender everyones definition of "Ultimate" is different so it will be virtually impossible to make the ultimate setup, for example rwd vs awd, singles vs twins etc - as you know its the entire package that makes the setup not just a good bottom end and a fancy head

[r33_racer]

Thinking about it, you probably could use titanium for alot of those parts but everything would probably need to be casidium coated to work properly. Might stand half a chance then.

That is right though, everyone has a different idea on ultimate.

I dont think so Steve. all drive v rear drive doesnt enter the equation imo and neither does the single/twin debate.

For the sake of the argument lets put a hp limit on it, say 750 hp.

Every man and his dog would prefer the one with the fattest curve making the most torue early and the quickest spool, It aint rocket science.

The cock floppers building 1000 hp plus engines for no reason other than to look good on a dyno are just that.

The lower hp engine would probably make more power under the curve (average power) anyhoos and be a far more driveable combo.

Stevo - Ti Crank wouldnt work, Ti has no twist strength, its strong as f**k if you grab either end and bend it like a banana, but if you grabbed the ends and twisted they are no where near as strong as Steel

Ok well here's what i was getting at; im building another motor now for my GTR (no, nothings wrong with the current one), and im doing a spare head for it aswel just for the sake of trying something no one has done with an RB head before. (dont ask specs or details, will release when ready)

Now, its twin low mounts, target power at crank is 750hp same as your target Noel but also like you the fattest low end and midrange possible with an RB based block BUT still retaining the RB "revvyness". The first head is what one place call ultimate and the second is a totally different direction.

End of the day someone might come along and think its no good being on twins for example - cant please everybody so may aswel make what you think the ultimate is and be happy with that IMO

[Nee-san]

Is it wizard powered Steve ?

That would be pretty ultimate.

VCam inlet and exhaust?

[N1GTR]

Nope

Like I said, not done before

That is all.....

If you could buy Ti rods, would there be a market for them and what would be a realistic price?

[r33_racer]

You already can buy them and they are stupidly expensive. Last I saw it was something like $1200-$1500 per rod. If someone made them as an off the shelf item the price may be better.

If you had lots of money you would just get alloy rods and use them. Lighter and can handle the 750hp range with 10,000rpm indefinitely, might even work out abit cheaper then titanium rods.

There would be a market for them if they were cheap, however that will be very hard to achieve since titanium itself is very exxy. Its a shame, because titanium for the most part is very cool.

[NYTSKY]

You can get Ti rods cheaper than that, right Steve

[r33_racer]

That sounds interesting. They are prices from an american company about 3-4 years ago when I last looked at it.

[N1GTR]

Maybe

I think it's funny for all the expense, in the end the difference in weight is very small for the dollars spent between alloy and Ti.

[ezy_09s]

^^ Yes but you will be replacing alloy rods more frequently than ti rods if you plan on turning them past 10,000rpm.

Btw Ti 6AL4V billet rods can be had from $650 u.s each for small block chevy sizes & smaller.

But good alloy rods like BME's would be excellent in a street engine..only downside is size comparison to a steel or ti rod, which can be a pain when clearancing the block or girdle.

i think not Jack, As impressive as that graph is how would it look with another 3/400 cc hanging off the arse end.

[UWISSH!]

if i was going to build my motor again, which i dont realy plan on doing or what to do (costs to much) this is what i would do.

either nitto 3.2l or os giken 3.15l bottom end

full cleaned and prepped 26 head with hks v cam pro

GTRS twin turbos or trust t617s or what ever they are called

manifolds all port matched and that crap

nismo or hypertune plenum

dry sumped

hollinger box and upgraded diffs with good ratios.

i think the setup would go quite well, good response, good power and hopefully pretty reliable

nath, pauter do good Ti rods at not too bad a price. but for me alloy rods are a good option. cheper than Ti and lighter too. no where near as strong so may need replacement every now and then in big rpm/big power engines (but i'm talking like 1000hp drag engines etc). the only downside is as someone mentioned they need to be physically larger to be strong enough which can cause problems in a 26 where you don't exactly have a shitload of rod to block clearance to start with...
