Close! it's 6,000 because you can't rev an rb30 beyond that no matter you do with them

all things being equal, you can always rev a motor with a shorter stroke more no matter how you build them.

That rb 30 z is a drag car, would be totally useless around a track and irrelevant to the ops aim. To get any torque or power out of that thing it would have to be revving at 5000rpm and have nos to get it on boost just to get it off the line.

That's fine, but for the average joe blow on a "normal budget", why would you want to rev the thing past 8000 RPM.

You dont need to.who said you did. but it would get there at the same time a 30 will get to 6500. 26s spin up a lot faster because of the shorter stroke thats my point

So if you have a rolling run from say 4500 RPM in 4th, both engines make the same peak power but the RB30 has more torque through the mid range will still accelerate the car slower than the "rev happy" RB 26?

4500rpm in 4th is same speed as you would be changing from 2nd to 3rd in a RB26 :pirate:

In neutral maybe.

Not when a torquier engine is pushing 1500kgs.

Rb30 would kill it of course with the extra torque, but put both in there sweet spot the 26 cover a greater rev range in the same time if you had identical power and torque figures, which of course you dont. be interested to see this on a graph though.

If you think torque isn't important go back to the graphs and look at the torque readings when a turbo engine comes on boost . Homologation specials like GTRs are not IMO a great example of what production turbo engines/cars are like - because its reason for being was a narrow focus special . Typical production road cars make more torque (same engine/capacity) in turbo form than the NA versions do and surprisingly , for some , at lower revs than the NA ones often do .

And who is saying torque is not important.....geez

I am going to take my 70 kw alfa33 out for a trashing now just to prove to myself that...don't know but I am taking it out anyway....I know carbies are better than FI. Hopefully I can find a vl.

    • Those car show concepts from the 2000's and 2010's like the Floria and IDx were brilliant and should've gone ahead, at least one of them. But neither Honda nor Nissan are thinking about affordable performance any more, which is truly sad.  Even if Toyota's liquid hydrogen ICE development reaches the point where it's commercially viable and the infrastructure to support it, Honda/Nissan would have to wait until Toyota allow fee access to their patents to offer it with any smaller performance models they released to take advantage of it.  
    • A sporty manual RWD coupe with a IL4 Honda engine would only be a good thing I assume we won't see anything released for a few years though, unless informal talks and designs have been going on for a few years,  and due to the current, and future, emmisions and safety requirements, I assume anything "sporty" they would do would be at least some hybrid thingie And hopefully anything they are thinking of has nice lines, without lots of plastic and fake bits hanging off it like that horrendous FK8 that looked like it was designed by a 13 year old The other issue of course in the current market is cost, currently the type R is around $70k, a twin is around $50k Meh, I'm old and grumpy and would rather buy a older model car and waste my coin on that than buying anything currently available new  
    • Nissan needs to forget about building SUVs in every size possible and bring back the damn Silvia/200sx duo to compete with the 86/brz. Maybe with the Honda type r motor pointing the right way
    • Good to see you followed your heart, got your dream car and have it pretty well sorted out now. I think anyone can get caught out with a seller not being 100% honest about a cars problems. Can relate to all the electrical issues, had similar issues with my first car (mk2 escort) ages ago
    • I just bought the Nexus S3 for my gtt, haven’t installed it yet as I’m collecting parts to do everything at once…so far spent $14,000 The Nexus is nearly future proof
