Dale's silver 33 gtst came off the rollers last night. standard engine with gtrs turbo, 550 jectors, gtr fuel pump, plenum, fmic and zorst.

255 rwkw at only 1 bar of boost and an excellent delivery.

Unfortunately dale wont get to enjoy it for a bit as his hicas crapped itself on the way home and the car is steering like a drunk on stilts. could be a good thing too with greasy roads and an extra 100 hp. :thumbsup:

  • 2 weeks later...

hahah yea :P, Well managed to fix the hicas up abit, but the suspension is still stuffed :unsure:

Lost the internet for a while so was unable to update. Tune went very well, as Noel said. Car has a very linear powercurve. very nice to drive, As said also Suprisingly with only 14 psi made 255rwkw, on a safe tune.

highly Recommend Mick from Signature. :)

chucked it on a dyno down here in bris and it reads 10kw higher. So I doubt Micks dyno is happy at all. Infact i think its smack on accurate.

regards,

dale.

RB25 stock ecu cannot be edited, I think however the R34 neo rb25's can recieve the "dr drift" style remap chip...

You could however use something like an apexi safc to map the afm's which can be quite benificial, however it depends on how far you wanta go with your car in the future.

R33 owners/RB25 users go for aftermarket ECU's, must commonlly the apexi powerfc as its easy to use and very cheap in compairson to others on the market.

However that said, its a bit hard finding them at the right price these days as apexi have stopped production of the ecu due to lack of supply of a certain chip from Nec.

yeh i knew all that, thats common knowledge these days, i can get pfc tomorrow if i wanted but iv got the car where i want it, but iv heard that production of the chips that can be used for rb25 ecu's has started again, well you could always get them but they were way to expensive equaled roughly same as install n tune of a pfc plus alot o dikin round..

anyways i went there today n hittin up a power run tomorrow to check my afr's n shit.. car isnt in ideal dyno state at the moment but iv got parts here waiting to put on so would like to se before and after runs

There are options for tuning the stock R33 ECU but they require working 3 chips at once and not many tuners do that. About the only I know that might is Dr Drift, but that isn't a recommendation.

Take a look at the ways some guys are approaching using a GTR32/33 PFC to overcome the lack of supply. There is info around the forum.

Yeah Geoff "Dr Drift" did have a solution for the stock R33 ECU however it was easier and cheaper to buy a pfc and tune it.

So in short it was deemed a non-practical exercise, plus most tuners know the pfc and can tune them well with a datalog as where the dr drift stuff is not distributed all that well.

You have limited options to getting that tuned in QLD, I believe Mercury is the only place that can as they bought the rights/software to it in QLD or something like that.

2gceffy, so your just dyno'ing to check where you at before you play with it yes? So what are you asking when you say "Does anyone know about stock ECU's?

As I must have missunderstood what your asking when giving my first responce.

just curious to see what he is knowledgable in, i started makin a 300zx ecu into rb25 but couldnt be bothered ay i lost interest, you only need to swap round some pins and piss off a heap. the 300zx runs vct so you can tune it to rb25 very easily and you can rom tune them like r32,s13 ect im lookin to running a high flow again n that so might try it again one day......

prob should start back up on that ahahah

    • You can’t see much on the other side as the lcd is there I don’t think it’s the same as the m33 beside it as the markings on top is not the same was hoping someone had a good quality photo or if they just happened to have the unit in hand, quickly take the cover off and take a photo to clearly show the marking on top to identify the diode   the unit is currently with an electronics repair shop so I can’t take another photo at the moment hopefully they are smart enough to know if it’s a zener diode or not
    • I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.
    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
    • Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.  
    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
