Disadvantages Of An Rb30?

[ynhrgt]

With the increase in displacement obvious, are there any disadvantages to using an rb30? I've heard with an rb26 head, the ability to rev is lowered substantially. Would this still be the case if the crankshaft, etc.. all were machined, counterbalanced, etc...

That didn't make any sense.

That didn't make any sense.

it did to me. he means do a search. it was asked this month already.

do a search next time noob

rb30 crank = shit according to the man building gtr-700 atm at croydon...iono if he wants me to spend 6-8g on a hks crank tho..

could be trying to get me to spend a bit...he said 26 crank is way better

rb30 crank = just as good as a standard Rb26 one, neither are fully counterweighted. In the case of the Rb30 unit it's less of a problem since you don't have to rev it as high as the RB26 to make the same power.

i have the rb30 with 25 head, i cant see any disadvantages at all honestly

yeh but you can't rev it hard bro.

That's why the rb20 is da best engine bro.

[Bl4cK32]

mine can rev...all the way to 7k on std cams.

Bite me anyone who says they dont rev.

[paulr33]

and why is revving higher a good thing? more fricton, more heat, more stress

you dont need to rev the rb30 to 8 grand, thats the point of it.

you can make more power at less rpm, the ideal combination

[TTT]

it was a joke post man..

far out.

[2BNVS]

yer my redline is 7800 and thats fine everything is sweet at that point

Go drag your knuckles eleswhere barbarians. Take your slow revving tractor engines, grab your straw hats and flanno shirts and go tractor pulling...push over a few cows while your at it.

The RB30 has never won anything. The RB20 won the ATCC

Other then rego and cost, is there a disadvantage...Oh Nissan didnt give it us as a std motor

Haha groundhog day for sure. Hey 2BNVS who built your engine if you dont mind me asking? I've been interested in one for a while now, just looking for someone who knows what they are doing and some prices.

ahhaha nice call, who calls 7000rpm high revving anyway, my vs commo almost does that

go the high revving engines anyday personally, much more fun when planting out of corners and its hitting the limiter almost str8 away at 9000rpm+

checkout the supra vs mines gtr video and compare the revvy nature, and response/speed the rb26 hits redline compared to the supra 3L, no comparision

sports engine vs torquey engine.

revs rule

[TTT]

pfft

[CruiseLiner]

pfft

is that all u can say?

each to their own mate get over it, go enjoy your 3L power/torque its only my opinion

[TTT]

it was meant to be light hearted fella.

no harm done.

I should try to use smilies occasionally.

[rev210]

yes revs rule so throw away these RB motors and fit a motorbike engine!!!!

Aaaaand (for Roy) there are plenty more bike engines with far more winning pedigree than any rb motor

RB20s do suck. I was in a a car with an L28 and it would blow the doors off my car, how old are they again. :confused:

I often wonder what the R32 GTSR would have been like if Nissan didnt invest so much money in the GTR to go Touring Car racing. Would it have had the GTR panels (alloy) with an evolution of the RB20, ie the GTRs solid lifters,6 throttle bodies etc? And kept it rwd to be in line with earlier Nissans which were light, mid power cars... Its a shame they built the thing to go Grp A racing, as i understand that if the capacity had exceeded 2.6L then it woudl have meant either a boost restriction or weight penalty...thats from a grey memory so dotn quote me on that.

I sit back and wait for the new GTR, a car that Nissan/Renaoult are building for a market, not racing. I suspect of the R32 wasnt for racing it would have used an engine bigger then 2.6L

As for talk about RB30s beign truck engines, its kinda funny. You look at M3s, some of the greatest 6 cylinder engiens gettign aroubnd, you read the reviews of its revvy nature etc...yet ppl seem to think dynamically the RB30 cant rev ????
