Big Power RB30 Engine Build

[plkettle]

dont think this is the thread to have that discussion tbh....

you will just come across as another tuner thats trying to discredit the competition without any facts or anything to back up your hints that it cant "produce the goods", it just seems like an obvious statement for you to make.

I would like to see the results from the maps done on the RB30's tbh

you should start a new thread about different engines and post up dyno graphs of similar spec rb26/27/28/30 engines to show a good comparison.
At the end of the day having more displacement can only be a good thing and the reliability of the rb30 from what i have read seems up to the task so far !

The quality of workmanship there looks amazing !

Whatever!

On an honest note, the RB26 is not designed to be a torquey engine, as was my STI Subaru, I'me trying to get the torque from the RB30 for low down power which the RB26 never had, untill the turbo's kicked in, the rest speaks for it self, suffice to say 700bhp is enough for any road going car. Reliability is the biggest thing, how many reliable built up RB26s are out there??

Also having all that power, Pupsi make sure you can handle it. Go and take some advance driving course on a race track and learn the handling dynamics and how to get the most out of your 17k engine

Thanks Adey, Dad used to race BMW 3.0 csl, in the old days. He's going to teach me. Should be O.K, but I will be enrolling on one of those track day's.

Firstly, I'm in favour of this discussion 100% so don't get me wrong here, but:

You must ask yourself:

Q: What did R.I.P.S actually supply for your old car?
A: A shortblock only.

Q: What was bolted to the top of the shortblock we supplied?
A: Exactly what it had on the 26.

Q: Did we have any input into, or did we supply any of the parts that went onto the shortblock we supplied?
A: NO.

Q: Did we have anything to do with the install or mapping of the engine?
A: NO.

Q: Was it commented on that the head and/or cams were no-where near worked enough/big enough to make full use of the larger capacity bottom end?
A: Yes it was, by the person who was mapping it.

Q: Does a shortblock really have ANYTHING to do with actually making power?
A: NO, not really.

Q: Did it make considerably more torque than it use to?
A: YES.

Q: Was the oil pressure, compression and build quality to a high standard?
A: YES

Q: Is it possible that because the power curve is much smoother/wider it just doesn't give the top end punch it may have had before but it is in fact still accelerating just as fast if not a bit faster?
A: I'd say so.

Q: Was the customer service I gave, build time (2 weeks), shipping time (3-4 days) and overall value for money top class?
A: I believe so.

Q: Do you seriously think that by just bolting in a RB30 bottom end and changing nothing else, giving it a re-map the thing will majicly turn into an absolute monster?
A: Of course not, thats just silly isn't it.

A big hit in the top end may feel cool and really quick but side by side the same peak powered RB30 will be quicker in acceleration, around a tightish track or on a drag strip.

If there's anything I've missed feel free to add/comment.

good reply rob, i am building my own rb30 and rob has been totally helpfull with all my questions, this is sometimes missing in the uk. pupsi has gone to oz/nz for his own reasons for a motor, it seems a shame that an nz or ozzie tuner is needed to help guys achieve there goals for power. we dont all have bags of money under the bed, but would like to achieve more and in doing so go farther afield.there are several people with rb30,s from oz now and not one seems to have had a problem or if they have they have kept it quite. remember its torque we want and the rb30 gives us just that..bernie

[pupsi]

Money side of things, I don't have the money, but to do what I've done, I've had to sacrifice a lot of things to get the finances together, granted my Dad's paid for it, but at a price to me. After my exam results, according to my grades, which I achieved to my Dad's satisfaction instead of buying a car for me for 15,000gpb, I decided to use the money to go down this route, I wanted it so bad I studied real hard, didn't go out with my mates, because I put my education first and this is my reward. Believe me it was hard.

As the post above, well said.

First of all Rob i dont knock what other tuners do, we all do our own thing our own way and all come to similiar results.
I was just wanting some feedback from other Aus RB30 owners to see if they were happy with the results from there package.
There are many over here now and the only one,s i know of have not realy shown as good as the OS RB30.
Mark spent alot of time and money into his project and then to sell it ! he was obviously not total happy with the results.
I drove the car recently and felt it was a bit lacking in performance for a 3lt
hence the first post .
Your workmanship is certainly much higher than mine and many other tuners,
you have a great following on here and i,m sure there are many happy R.I.P.S
owners that could back up your claims of performance in the UK.
so come on boys

[RKTuning]

I think i,ll go back to not posting it,s less hasle

[R.I.P.S NZ]

No problem at all with any of your comments, as far as I know Mark sold his car because he got offered a sum he couldn't refuse, in any case, I think we all agree that adding a RB30 bottom end only is not going to vastly transform the car.
You will also probably find that the OSG boys usually have pretty big budgets and have installed suitable parts to go with their OSG bottom end hence the 'better results'.

I am 100% confident that if Mark, for example, installed an OSG bottom end instead of mine, (and spent big money on the OSG pulley and flywheel/clutch etc) it would have made absolutly no difference to the outcome in this case as the bottom end is basicly just a pump with a certain capacity, would you agree?

In cases where we have been in control of the entire engine build and actually installed and mapped the cars here, I feel we have had great results for the money spent.
Eg: Totally stock internal RB30 bottom end with a totally stock RB25 head, stock cams and springs etc, stock RB25det exhaust manifold (2k pound long motor), stock box etc 10.21 in a street skyline on pump gas, I'm sure with a sequential like yours we could have wound in more power and run 9.7 - 9.8, thats pretty good performance for the $$ and isn't it similar performance to the red skyline in question when you you owned it and had a pretty big $$ RB30 in it?

UK001: Bottom end basicly the same as Marks, totally stock head, stock gearbox, 1st time out 10.7 in crap conditions, once again, with some track time and a sequential its a 9 second car.

My new car will be running in a week or 2, it has the exact same bottom end I sell to everyone else and with a bit of setup time I genuinly expect low 9's to high 8's in full street trim with pump gas from this car, maybe once thats done we'll be considered nearly equal to OSG,

[nismoman]

not wanting to start any kind of argument,but far play to you Ron, that is a valid question based on your experances,i think a major factor of the rb30 from auz over the os 30 is the price,yes there cheap,and that will be the only factor in some peoples eyes.me personaly i favour the os30 based on the information of people running them in the uk,some in road form ,some in compertition,but as of yet i dont know of anybody personaly running one in the uk.but one thing i would say is i would have no problem about useing RIP from what i have seen from there work( some in the uk should take a look at RIPS work as a example to how we in the uk would like standards to be).so once again Ron has a valid ,i think ludders has a RIPS 30 and has had some compertition use ,and i think his car has gone over to RIPS so when its finished the car my prove how good they realy are nismoman

[R.I.P.S NZ]

I think the main thing is to make sure we all compare apples with apples.
Most tuners given a suitable budget can deliver good results and as Ron says we may go about it differently but usually end up at the end of the strip in a similar time.

Our engines started off as real low budget, stock internal motors that reliably ran 10's in street cars, as we have become more known the budgets have increased and so have the expectaions of our customers which obviously is fair enough.

In an open season, no budget war, I'm quite sure that the OSG, at this stage at least, is a better option for guys wanting genuine reliable 1000whp+ bottom ends but keep in mind they'll only make as much power as the rest of the combination and mapping will allow.

Untill we have tested big hp on our bottom ends/motors ourselves (which will be done very shortly) I don't want to comment or tell customers our bottom ends are of an equal quality to OSG.

Ludders ordered a 600-650hp package but we did NOT supply the head or have anything to do with selecting parts that went into it, we just supplied the bottom end, intake plenim, exhaust manifolds/turbo's etc.
It was put together by one UK tuner and mapped by another.
I believe the mapping was done correctly.

With very little experience, in full street trim, full weight, on low profile street tyres, pump gas with no NOS and a stock box he ran 11.2 which I think is more than acceptable for what he asked for.
I'm sure ther'd be plenty of guys being charged for, or saying they have 600-650hp that don't run 11.2 in a full weight 34.

Might pay to start a new thread if we want to discuss this any more....

Hi Rob

The OS 3L will rev to 9000 revs where your RB30 wont
I was told at totb that Ludders rev limit in his R34 was 7200 revs
what use is that to anyone on a drag strip
that extra 1800 revs will make the OS 3L feel much better.
