Rb26 Or Rb 30

[BMYHOE]

you like 400rwkw @ 4100rpm?

rb30...

[NZM.031]

i have not been in an rb30/26 car... quite frankly im not that keen to. a high powered rb30 just doesnt hold that same appeal to me as a high powered or even mild rb26.. its working with what the car came with from factory.. making the best of what youve got. engine transplants are just like plastic surgery... your car may go good.. but everyone knows that its not what it was born with.

i hold rb30 powered gtr's at the same level as VL drag cars.. its just not a gtr anymore.

and to say that japs are scared of big things.. and thats why they dont use them... maybe its because they just dont need to.

why dont we all just put twin turbo LS2s in our skylines.

your boring...

engine conversions are mad!!!

especially big powered ones in light bodies!!

Show me how to put a twin turbo ls2 in my gtr and keep it 4wd and im up for it. lol

Mate, I totally agree!

For those who want it, fine. It is definately a personal choice how you want to modify your own car.

For me personally, I do not want a mongrol engine in my pure-bred Jap sports car. An RB30 is just like a pig, it is a dirty animal, put it in a clean environment and it is much better, but it is still a dirty smelly pig!

How is that for a pot stir? 2.6L all the way.

All these naysayers, have you been in a car powererd by a twincam 30?

LOL, i like your style..

lets see you rev a rb30 over 12,000rpm !!!!!!

I didn't question ability of either engine. The idea of owning one does not interest me so why would I want to be in a car powered by one?

If you can do the same thing, as in make good power and run good times, with either capacity (i.e. either block) then what is the big deal? It is a personal choice which way to do it. There is just a bit more pride and class doing it with the original capacity.

Who needs to rev their rb to 12000rpm?

Build a 30/26 rev it to 9000rpm and make 553.5 kw at 4 wheels on pump fuel.

And hang the fu{k on. YEA MATE.......

I beg to differ. I feel there is more pride and class in building something different and why would you balk at more torque, earlier power and better drivability?

Better yet, hands up all the cheque-book racers!

Now THAT'S what I'm talking about!

Your opinion, that is what these forums are for.

More power and torque earlier, fair enough. But the same times on a drag strip and/or circuit can be achieved either way, so, again as I said, it is a personal choice.

[Sheriff Wan]

If your builiding the car for street use you simply cannot go past the 30... Simple as that.

And for all you pure breds out there - get with it, the RB30 has been mated with all RB's with great results. Like it has been said before if you can have more power & more torque earlier why not?

Also for all who are saying lets see it rev to 12,000 rpm - that is ridiculous as we are talking about a STREET car, do you rev your car to 12,000 rpm on the street - I would hazard a guess you wouldnt get near or even need 10,000 rpm.

Look at superjet760 - as if you would say no to that!!!

My 2 cents...

[donkeypunch]

hmmmmm, i do like the idea of keeping the RB26 in my car, my R33 is pretty standard looking (except the LMGT4 rims), no gauges, not lowered etc (except the engine mods) good for resale, but the RB30 sounds sweet, i sponsor robbie 'RIPS' wards car, maybe i should fly up and have a spin in an RB30?

[superjet760]

just remember boys revs are what kill engines.

So if you can make the same power with less revs and less engine wear then why not? A 3l

BTW give me a billet 3l crank and a R.I.P.S billet main cap bottom end and il go rev for rev with you all the way to 12000rpm

if thats what you like doing. but i cant see the need

Yes it is my opinion, aswell as many others.

More power and torque earlier means more average power, which makes for a faster car.

Dude, look at the times from drags and circuit. You can do the same with both! More average power, over a certain rpm means dick all if you spend your time between 4-8.5k.

Do you want me to get Chuck Norris so he can explain it speaking braille to you?

Uhuh. Nice one.

You just made a very nonsensical comment there man... "More average power, over a certain rpm means dick all if you spend your time between 4-8.5k. "... if you make more average power between 4000-8500rpm (thats a certain rpm) and spend all your time there, then you will have more acceleration/response between 4-8.5krpm, very very simple.

I don't know why you guys are going on about the RB30 being shit/old/whatever, if you use the RB26 head then you have all the advantage the RB26 has an a dirty old iron block thats 3litres instead of a dirty old iron block thats only 2.6litres. They are both dirty and old, its just that one is bigger than the other. It seems there is a lot of confusion of the old days when the old 2.6litre RB26 beat the older 5litre Oz V8s due to technology... it didn't win because it was smaller, it won because the stuff it had it used better. The ultimate is applying the technology to bigger displacement, you get the best of both worlds.

Look they are both nuggets that empty my wallet, keep me busy, make me drink a lot, force me to spend less time with my family, make me loose hair, made my nuts twist in their sack etc...etc...

Some like pepsi...others like coke...

some like racing cars...others like stacking pallets...

who cares...pick an engine and love it, flog it to death, have some fun and scare the sh1t out of your mates with it.

I love the RB engine from RB20 to RB30...

My engine will out torque nearly all RB30's ive encountered and matched the ultimate torque engine RB29 from racepace in all but the very low rev range and was all over it in the midrange where it really counts.

Even the RB25 i just built for NYTSKY matched torque figures with a 400KW 2JZ...its not what you build but how you build it. Just because you use a bigger bottom end does not save it from being a bucket of sh1t.

Wait till i get into the RB30's...ill have a few surprises im sure.

I find it strange anyone would choose a rb26 over a rb30. Less torque and less power. Why would anyone prefer that. Pride is not an excuse either
