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.

      "Cheap" bolt on turbo on RB25DET NEO

      By GTSBoy · Posted

      The HG high flow is excellent, and costs about the $$ you're talking about. But it, and probably every other highflow, uses a diffeent core than the original turo, and the original Hitatchi core is quite long. So, I think it is inevitable that there is likely no such thing as a highflow that just "bolts on" with no other effort required. And the same is likely true for HG's outright replacement "bolt on" turbos (the ATR things). And the same is likely true for anything similar from elsewhere. I have no idea if the cheap Chinese/Taiwanese complete turbos from eBay/Temu/etc are as bolt on as they claim. I mean, they claim the bolt onto the NAs as well as the turbos, and we know that can't be "bolt on". But it wouldn't matter because I'm not buying a $169 4 psi turbo for anything other than a paddock basher.

      Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD?

      Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.

      So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!

      OK, few more things sorted and it is ready for a shakedown on 10-Oct, with one weird thing. Changed the run in oil and filter for the good stuff. 8l came out, about 8.5 went in with filter so that looks all good. Changed the starter (again), this time for a brand new one, works good. Interesting that the Taaaarks one is shorter than factory but spins harder, I guess electronics have moved on a little in the last 30 years. Will be nice to have a bit of extra space under there. Put the timing cover back on, and noted where the cam gears were set as a record.  Will need to double check the timing but it is pretty close. Also put the coil pack cover and intake snorkel back on. Exhaust Inlet Changed the water out for coolant, bled up nicely. Removed the rear brake pads (well worn factory sumitomo ones!), gave the hardware a good clean and reassembled. I've put bendix XP on the back again because the price is excellent at $150 a set and they worked well on the V37. Front pads have plenty so no issue there
