That's what I built the site in my signature for. It's not 100% accurate but it gives an indication of the differences in response and top end. I already uploaded my tuning graph from a few weeks ago so it would be good to see yours, MII32 (I think? sorry I didn't catch your name) and mine.

I haven't taken photos of my dyno graph yet, my camera's stuffed so have to borrow a cam from my mate first. I will have a look at the site u built on dyno graphing comparison~~ MII32? LoL i only have normal plates mate, name's Jyo, with the white gtr32.

Yeah, I know, I meant you, me and MII32 but I didn't catch his name. When Mark put his graph over mine the curves were very similar except mine came on earlier. Would be interesting to see all three.

Icic willo...no wonder i was a lil confused when i thought u didnt know who i was~~ :whistling: I think the "MII32" u r referring to is "DT GTR"(SA plate). That's Danh, his forumname here is 9krpm. Yeah it would be interesting to put all the curves with different twin setups together. That said, u guys whipped me by 40hp @ 4 wheels! I think i need to move on from poncams to procams, have a re-tune and get 6/4 brakes. LoL. But awesome results on yer 2530s mate~

That's the one. Saw the back end of too many cars on Saturday, they all start looking the same.

You're also running N1s so you'd expect to have less top end. I'd imagine your's would come in a lot sooner though. The problem a dyno day is you always come away wanting more. While I'm more than impressed with the 2530s so far some more aggressive cams and another 500-600 rpm to play with would be nice.

It was very interesting to see that too. Thanks Mark & Willo.

Your car setup is very nice!!!! What cam, pistons, rods and gearbox have you got in that beast?

I like ur midrange response. I am thinking of selling my engine and build a 2.8 late next year for track work.

Jyo curve has less power than mine at the bottom end as well but he is running more conservative boost compare to us. It's a shame that he is selling the car though. Hopefully it will go to a good home and we get to see it out on the track as often

HKS 264/9.15

CP Pistons 86.5

Crower rods

Standard BNR34 gearbox

I figure if Mark can squeeze 1100+hp out of a RB26 and I was already happy with the response of the 2530s I didn't need to go to the expense of a stroker. I think some bigger cams are in order though so I can lift the rev limit to around 8500rpm and hopefully squeeze some more out of the setup.

Nice work willo. how much boost are you running to get that power?

I've got the same cams and have been reving to 8.5krpm without any problem in the past 2 years. A larger cams might be good for the drag strip but may result in too much lag for the circuit, if not tuned properly. More power in the midrange will help me more on the track.

The 500hp run was at 20psi. All the head work done is good for 9000rpm but peak power comes on just before 8000rpm so there wasn't much point pushing it any further.

      NC MX5

      By The Bogan · Posted

      Purchased a NC MX5 a while ago Basic suspension mods done, BC coils and Whiteline sway bars  New DBA calipers, discs and pads Added some 17 x 8 Konig Decagrams with 215/45 17 PS5's Added some typical NA bolt on's, i.e. full exhaust and intake  Added 0.5ltrs with a MZR2.5 swap, nice bump in torques  Found a detachable hard top which is locked in for a colour match with my local paint shop in Feb 25, this also includes some PDR as it has received a few love taps from parking in the local shops when in the hands of my Minister for War and Finances, me, I park nowhere near other cars and typically park on the street The little thing is awesome, I drive it everywhere, it handles like a dream whether I'm up it or just cruising  But now,  because I'm a idiot, I keep looking at turbo kits....... did I mention I'm a idiot Why is dose so appealing  All of the NA 2.5 glory, well.......until sometime in 2025 anyway....🤪

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      I would not be surprised if you are the only person on earth that has the interest/desire to do that lol.  The Haltech base map is a really good starting point, the car will fire easily and drive very well, even on mild boost levels. To me, following your advice sounds like some sort of ancient Chinese water torcher lol (this is not an insult Josh, never change <3)

      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
