Hi guy's today I finally got my Rb30/26 base tuned. It had been run in for around 700miles so was more than ready! As I had some fluffy running issues during the run in period I decided to get a base tune done with the stock pump and AFM's to make sure it was all running clean prior to swapping AFM's and more than likely the pump for my future plans. After some minor tweaks richen up the map off boost and load the running issues were all pretty sorted so we went for a couple of power runs starting at 6psi wastegate boost to give the car some initial runs up to 6500rpm. Once happy with that the boost was increase to 0.8bar and some further tweaks were made. At this point the Stock MAF's were pretty much maxed out so I called it a day but here is what I ended up with so far.

I think the rpm scale is wrong so ignore that. It was revving just short of 6500rpm. The power shown is flywheel power and it equated to 324bhp at the rear wheels I was hoping for a touch more but then I had planned to run it up to 6750rpm initially then I got a bit nervous!

The engine is running HKS step1 cams with adjustable pullies so I am hoping to dial the power ban back a touch to make better use of the cams when I go for the final tune. The 660cc sard injectors are happily run at about 60% duty at the moment. Whether or not I need to put a slightly larger pump in remains to be seen.. Anyone have any clues as to how much wheel power a stock gtr pump can hold on an RB30?

Knock levels are max 28 at the moment but then boost is still relatively low. We tried to fiddle with the ignition timing a bit but it made no significant gains at the current boost so we left it as it was .

I plan to drive it as is for a couple of weeks and make sure I am happy with it all then I will put on my larger MAF's and pump if need be and go back for a final tune taking the rpm up to 6750 limit. Maybe a little higher. I am hoping I can get into mid 500's flywheel power but not sure I will get there yet? My tuner on the other hand seems pretty confident!

If anyone has any thoughts on my printout let me know. Wouldn't mind comparing with what other people have made on the same boost and similar setup?

Sorry i missed your build thread - what is your set up? Turbos, ecu? How does your chart show flywheel hp - have you pulled the motor out and put it on a bench dyno? If your pump is the original stocker progbably good idea to at leat get a new Denso equivalent. For comparisons check out http://www.skylinesaustralia.com/forums/topic/104332-rb30-hybrid-upgrade-all-dyno-results/ and be sure to post yours in there when you have your max boost results!

Hi There,

I am on a single turbo and Apexi ECU, HKS Step 1 cams and 660 sard injectors. Stock pump art present. and Stock MAF's. The print out I got from the dyno was the estimated flywheel one rather than the actual wheel power we saw on the day.

Cheers for the link.

      It's kind of interesting - They definitely do builds that split the difference between what they like and what will generate views and engagement. The NC Platform always surprises everyone in a good way, in an uncomfortably good way some may say. They could throw a LS in there and arguably have the best (and best performing) car of the entire stable. But that isn't necessarily what draws views, because people viewing don't want to accept the vegetables of a LS NC MX5 being a superior vehicle in every way (including fun) than a RB26 240Z. This is also why there's not a lot of content about the GR Yaris (on the web in general). They're too good, yet 'only a Yaris' The community doesn't want certain cars to be as good as they are - to beat their hero cars, and I believe the NC MX5 is absolutely one of those cars.

      Yeah - My key still does the chime thing. I followed the procedure but it didn't activate on the (identical) third set of keyfob that I had. I vaguely remember the alarm saying you can only pair two keys with it. Now that I've dug it up, it appears that you very much can pair keyfobs to the alarm system. (which are the fobs I use to unlock the car). I have successfully diverted the thread and can probably not use the OEM keyfob ever again unless I use the aftermarket alarm and attempt to pair the OEM keyfob to it. Which might just work, or not :D. I definitely used the nissan method and not the aftermarket alarm method.

      What makes it worse is that Nissan made keys in the same style, for example R34 and Stagea, but they work at different frequencies or something like that. So they look the same but the remotes are not interchangeable. I learned that from some guy selling aftermarket blank keys.

      Does your door chime work when you have the key in the lock and open the door? I've had that disabled because it's f**king annoying and it is one thing that messes with the pairing. Because now the car doesn't detect key in ignition anymore and the slide-key-in-and-out sequence does not trigger the pairing mode anymore. The service manual has a section on the various bits involved in doing the syncing. I presume it'll be similar between Stagea and R34.

      Agree, but meh, I think is is based more on LOLS than actually apples to apples, like, who would have thunk a turbo 4 cylinder would not beat a NA 4 cylinder  I think with just basic N/A mods, like a exhaust and tune, it would be equal to the Mini in its current form, maybe I know my current 2.5 would "chop the mini" as the midrange now has a night and day difference in power delivery compared to the tuned 2.0, by around 20kwatw and 30nm from around 2k rpm "ish"....... I'm kinda hoping that they do a N/A build, either with the MZR 2.0 or with whatever they decide to use If I recall correctly they did talk about K swapping one a while ago
