Marko we all know the reason you don't like rb30s is it had to much low down torque and you looped it and smacked a wall

We ALL know? You are a champion lol and I must say, thank you for sharing that - 10 points to the man with the microphone! Besides, I wouldn't go shooting off remarks like that unless you understood the root cause and in fact why the rear tyre peeled off the rim.

Your comment has no validation to capacity what so ever.

I had the opportunity to keep my rb30 and decided not to which clearly demonstrates that I prefer an rb26 and subsequently have my old car back...I've been there and done that, I've had my fair share of clapped out imports and now have my aust gtr :)

Tyres don't just peel off, I'm sure you know that, the force required to unbead the tyre from the rim is quite substantial and could only be caused by the rim/tyre impacting the gutter or pot hole from hell

I have seen tyres go flat and people drive on them until the side wall separated from the actuall tyre, but the bead was still attached to the rim.

As for capacity, on the street the rb30 would always be the best choice. cause I like drive up a hill with my a/c going and not have to change from 4th to second to get up there

How can u draw a conclusion when u don't know the sequence of events? This is way off topic and again simon, I apologise.

Sorry if I have been abrupt but I shouldn't even have to apologise on this front...

Rb30 is an awesome engine, so is the rb26

How in the world did we go from tyres issues to aircon. WTF?? :pirate:

So back to my build thread rather than chat thread. I don't at all mind the banter thats been going on in this thread for the last 2 weeks or so, as long as its helpful.

I hope to twist my other tuners arm this week and get the GTR on the dyno to see what he thinks is going on....

  • 3 years later...

Just read the thread, I see this finished mid 2011, does it still stand true that the 26 is better on the track than the RB30, the Nitto 3.2 strokers rev to 10,000 and do not seem to drop off after 7000rpm and continue to go hard to the limiter??

Maybe I misunderstood ?

No its not true that 26s are better on the track. It is true that there have been a few more highly developed RB30 32 and 34s built in the last few years and they can indeed rev to 10k but at the end of the day , when all's said and done etc etc the fastest car on the track will be the best built best driven car and the capacity will just be a factor, not the deciding factor.

Yeah, after reading a lot of builds it seems the strokers are starting to be developed to rev higher as well as having the low/mid grunt.

Seems the Nitto 3.2Lt seems to be a well made unit and can handle a heap of HP while revving to 10,000+

I am building a Nitto 3.2 but as a DD and probably limited to 8000rpm ish depending how it all works in together.

You will be aware that RIPS put a 3.2 (pretty sure it was a Nitto) in a Stagea and made 1000kw...

Rips have put them in a few Rs, MGAWOT 1 & 11 and @ 1500HP, they seem to do some amazing things. Nitto in QLD goes hard @1000HP+ :) CRD has done some quick Rs

    • How dare you sell your unreliable Skyline and buy a reliable, Toyota/Yamaha car with a strong gearbox, torsen LSD and Toyota reliability. At least you won't need to worry about oil pumps, big catch can, oil restrictors, blowing off power steering belts, sheering off 3rd gear, failing ABS relays/pumps, etc.
    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.
