In the process of selecting new turbos to suit 500~hp for street/track/drag use. I've looked around and nearly have bought some new HKS 2530's but the 2860's seem to be pulling some reasonable numbers. Anyone personally here making 500~hp with them care to respond about them performance ect?

Well they are basically the same turbo (2530/-5)

They will make 370rwkw no problem, same as a 2530.

Lots of results in the RB26 thread now with them, and anything that is "2530" applies as the same

So not sure whats left when there is plenty known already

They are not the same turbos as 25/30 as response and top end power will vary considerably but they are also nowhere near the price of 25/30's either. I have used them on a mates race car that i built rego 26R32 it came 8th outright in superlap and they are a good turbo especially for the price the car makes 497hp at all 4 wheels on 20psi boost with a set of tomei pon cams so they will definatly do the job as i would consider 20 psi not to be a lot of boost myself. I will be winding a bit more boost into them soon around another 5-8 psi with a retune and some bigger cams am expecting around the 550-570 hp@all 4. Graet turbos for the price in my opinion.

i watched as a GTR got tuned with these turbos(-5's), and it was really flattening off/boost dropping off at ~430rwkw on race fuel @24psi, so you could make your target power but you'll be really pushing the turbos hard

2860-5 are very similar to the 2530s

they make a touch less power compared to the 2530 and when pushed hard will make close to 500awhp

most people running these would be in the mid 400 range as pushin a turbo hard will shorten its life span

why not go a high mount big single external gate :P

So the 2530 loose bottom end but make up for it with outright power. While the 2860's come on earlier and drop off?. That seems to be the trend when researching.

Well by your own post, the -5's are doing exactly what 2530's do which is 370rwkw @ 20psi.

Sounds exactly the same ballpark to me.

And then they do 440rwkw on big built motors when pushed (see RPMGTR - which was on PULP and others)

So the results are sounding nothing different to a 2530, and from the info posted in the past about wheels specs are so on, there is little difference there either

Cheers.

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
