when would be a good time for a tune? In terms of mods

I would get a ECU upgrade + tune around the same time you have done all the basic bolt on power mods which are: turbo back exhaust, intake, FMIC & boost controller with upped boost.

& you can't tune the stock R33 ECU. You will need aftermarket one or at least a piggy back interceptor unit like SAFC.

Except you can get standard ecu remapped, there is Toshi on this site who does it either through custom mail order, or if you are in sydney, he can tune it on the road or dyno. Check his thread out. http://www.skylinesaustralia.com/forums/topic/298912-cheapest-r33-ecu-remap-only-400-also-r32-r34-and-silvia/page__hl__toshi

Pretty much NIStune but not as good.

And a fair bit cheaper.

Depends how you look at it. He charges $600 to install a daughter-board and write up a basic tune for it. Then he recommends that you go and put it on the dyno to check that it's safe. So probably $100-$200 dyno time. So it would probably cost you ~$700-$800 by the time you get it on the road. Most workshops will install and tune a Nistune board for ~$900, and then it's a proper tune setup for your car specifically, not just generically. Personally, I would rather pay that extra little bit to get a proper tune done.

true that, a fully suited tune is best option. But im pretty sure with the 33 you have to buy a Z32 ecu on top of that, could be wrong though.

I got my nistune for $410 installed. Then what ever it cost for dyno time on top. But like Krab said above, once you've got a boost controller and a fmic on your car then i would definitly get a tuneable computer. And from my experience and talking to a few others i would highly recommend Nistune, there are plenty of people getting big power out of them and because the daughter board attatches to you main ecu inside the ecu housing as far as anyone can see your still running a stcok ecu. And i doubt that many people would be able to tell even if they opened up the ecu. Unlike some other options where there is a big brand name stamped on the outside. All depends on what state your in. Ideally you'll want the tuneable ecu sooner rather then later. It'll let you get the most out of your setup as efficently as possible. Hope this helps.

R33 mail order remap is $400 for std turbo.

Group buy is $350.

Normally R33 with Z32 ecu cost around $1300-1500 in Sydney.

One other (possible) issue I'm seeing with ECU selection is that the OP's car is an auto (like mine), from reading some old threads not many aftermarket ECUs works properly with auto Skylines.

Something to do with that the stock ECU backs off timing when the auto box changes gears, however this feather is not available on any of the aftermarket stand along ECU (as far as I know), so you will get very harsh changes if you remove the stock ECU.

Not sure how it is now, as I said my understanding is pretty dated...

I know that PFC doesn't properly work with auto skylines, does Nistune work 'properly' with autos?

Last time I talked to Andrew from Hyper drive (few years back), he reckons other than converting to manual if I wanted to keep the auto box I need to get Emange Ultimate which is still a piggy back. In the end I just got a SAFC 2 since I wasn't planning on modding it further for the time being.

But I recall one of the WA mods having an auto Stagea & running a Nistune...

In regards to this thread ^ I have nistune in my auto series 1 R31 and i have a friend with nistune in his series 3 R31 auto and they both run beautifully. So if what you say is true then Nistune seems to be the only way to go.

Yeh bubba is using NIStune in his Stag. Not sure if he ended up removing the Haltech he had in there originally, but I think he is just using the NIStune now.

I don't see why it wouldn't work anyway. That's the big thing about NIStune, it keeps ALL your factory settings. So anything you don't change is still going to be the same.

      EFR7670 exhaust selection RB26

      By LegendGTR · Posted

      I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀

      Stock Airbox and Snorkle for RWC - VIC west

      Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?

      Duncan's V37.......race car?

      By PranK · Posted

      This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!

      OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
