Custom RB30 Crank

[DESCR8]

Hi Guys

Im currently looking into having a billet steel crank made to suit the RB30 since i am aiming at pushing the RB30 to its limit and also rev it to around 9,000rpm. I know some have done it with a standard crank but they havent lasted and i want to be able to rev it to 9,000rpm without having to cross my fingers im going to snap a crank.

So if anyone know who makes them or who i should speak to that would be greatly appreciated. Im also looking at having a billet crank girdle made to suit

Your probably going to get a few people asking "is this for street or strip?" and "Whats wrong with the std one?"

That said OS Giken do a 3L kit. Cant u buy their crank/girdle?

Nizpro also used to do the same job i heard, but dunno if they still do it.

U must have $$ to spend to build a motor like that man Hope its not for the street cos it wont last long

[DESCR8]

Well i already know all that stuff and Nizpro arent really that good to deal with if they arent building your engine, the money is being spent and i dont understand people saying if it a street engine it wont last thats the good thing about turbo charged EFI engines they can be detuned for the street i only want an engine that will last on the track which puts alot more strain on an engine than the street does.

Maybe ask around concerning the Sammut Bros 300ZX drag car which ran an RB30...

[DESCR8]

Roy: Wouldnt happen to know their number would you?

Can i ask what ur budget.....um limit is for spending money on this engine?

and i dont understand people saying if it a street engine it wont last thats the good thing about turbo charged EFI engines they can be detuned for the street

Then whats the point in spending 1500 on forgies, 2-3k on forged rods, 3k on a crank girdle etc etc.... then have it detuned to run on the street??

[DESCR8]

Mate. My aim is to biuld a low 9sec car that will last more than a couple of runs and i also want it to run without NOS. I also want to drive it on the street and to Dyno comps where i see fit because unlike all these trailer ponies i want to prove that it can be done.

Bl4cK32: To give you an idea i am using a twin 3037R kit or 3240 kit depends what i can find, should tell you how much power i want to make

so you can do both street and strip. Personally I dont think it will happen, but I would love to have to eat my words. Good luck.

Steve: Are you saying there is no such thing as RH9 cars or Keir Wilsons R32 GTR?

By the way i have upgraded to an R33 GTR its a VSPEC not that it means anythign down the 1/4mile

[Bl4cK32]

Someone should tell Munro or Kier that they can drive their 9 sec. (or is it 8 now) gtr's on the street, and have it reliable.

Someone else said it better - "I'd buy that for a dollar"

no need to be a dick.

and why the are you trying to prove you could build a car like Kier's, its already been done? nothing new

Whats it matter if its been done before??? Doesnt mean other ppl cant equally enjoy it

Though, id be just as happy with a high 11second GTR and a healthy bank balance, but im a poor sack so that weighs heavily on my thinking.

[DESCR8]

Steve: The only bloke being a dick is you im asking for some info on crank builders and all the know it alls come out and tell you it cant be done, besides who says im trying to build a car like kiers for you information this will be alot different only the time will be similar

Roy: Cheers mate, i think people that cant dont want those that can to do it, makes them feel kind of insignificant

Umm - u did. + u said u wanted to drive it on the street, and race it on a track.

No need to take offence there mate, were just stating it takes big $$ for the engine u speak of.

Why dont u ask Sydneykid if he takes his 25K rb31 engine down to the track, stip, + drive it on the street to the local Maccas.

[DESCR8]

I will next time i speak to him, anyway guys thanks for your info. Ive spoken to Nizpro and they said they will make me the Crank and girdle all up fitted and machined around $9000 if anyone else wants to do the same and they rate the rpm for 8800 which equates to a 25m/sec piston speed.

[Steve]

Er, yeah, if you re- read my post, you will notice that i said "I" dont believe it can be done, I also said, do prove me wrong, because I would love to see it, I also said 'good luck'.

You also mentioned that people are saying 'it cant be done', well hey I didnt say that, and, if as you pointed out Kier is already doing it, why even bring up that it cant be done.

Bottom line, I didnt say you were trying to build a car like Keirs, you mentioned his car, I didnt say you couldnt do it, I said 'I dont believe its possible', you are the only one here who is saying 'it cant be done'

So really, who is the dick? perhaps you should read peoples posts before you go jumping off the deep end? you remind me of a spoilt child.

if you cant handle someone elses opinion, or allow someone else to have an opinion, WTF are you doing on a public forum.

[Steve]

Roy, as what Bl4cK32 said

I took the statement that 'unlike all these trailer ponies I want to prove it can be done' and the I want to drive it on the street' to mean he wasnt talking about a car like Keirs, as there is nothing to prove there, it has been done.

Not saying there is anything wrong with Kiers car, but really, its not what most would call 'streetable' more like , 'its driven on the street' - world of difference

Just to be cheeky... 'THE RH9' car never even got to 9 did it?

oh well.

But yeah, why couldnt you drive it to macca, like seriuously.

are these race motors not allowed to be driven or something?

Me dont follow :aroused:

Huge cams, huge injectors, little power at bottom end, high stall converters/dog boxes - all make for a not so friendly road car, slug down low, and when they come on song, go nuts.

And very, very, very unlikely you could get it street legal, unless you live in queensland
