1998 R34 GT-T

  • Full 3.5 turbo back zorst with dump
  • High flow pod filter in cold air box
  • Manual turbosmart boost controller set at 12psi
  • Lowered on adjustable coilovers and sitting on lightweight volk 18s

Hi all, looking at getting a Nistune type 4 board for the above car (stock R34 ECU) got qouted $282 from Nistune.com in Adelaide. Does anyone have Nistune on R34 with the above mods or similar??

If so, what are their experiences / recommendations?? Is it a good thing with a nice tune?? If so, how long's the average tuning time - I'm just looking for a daily streeter with a sharp punch.

Any cheap but good tuning workshops in Sydney (I'm in Parra) - dyno guys who have Nistune exp and know their stuff??

Noob question - I have my stock turbo - is 12psi too much?? I've read varied opinions some say keep it 10, others say max 13 or even 14, but I know they blow at 14, so is 12psi okay??

Thanks - any help much appreciated

I had mine with very similar mods running on 11psi with the NIStune. Really happy with it!

Does everything and was a quick tune because it's already got the base map there to start with. I got 216rwkw i think on that setup.

Now last dyno was at 266rwkw with turbo, afm and injector upgrades, it's higher now but i dunno what it's at atm... NIStune doing a great job with that tune as well :thumbsup:

Best bang for buck by far when it comes to ECU's

it really depends on how rich or lean your car is. if your running really lean on high boost for those turbos then it will blow from getting too hot.

r33 stock turbos are quite finicky. if you really like your turbo id suggest investing in getting it hi-flowed and then you wont have to worry.

Im running a Nistune,

3inch exhaust turbo back, FMIC, Stock turbo..

boosted to around 16psi ( i know what your going to say!!! lol )

Car went from 150ishkw to 221KW. Massive upgrade.

Im not to worried to much about the turbo as its not my daily driver and i want to upgrade the turbo set up

I got mine done down at Envy Imports at brookvale, totally happy with it,and the guys down there are awesome.

Hi guys, many thanks for the awesome feedback, I reckon Nistune is a good go from what all I've been hearing about it, do you suggest upgrading my stock GT-T intercooler before going Nistune??

I dont intend to do additinal mods like turbo/injector/fuel pump etc, just guna keep it at stage 1 mods. And 'Random_I_Am', did u have any flat spots before Nistune and did that get cured after? Hows the car to drive before and after Nistune?? Differences, response etc.

My ones very sharp and responsive from down low, around 2.5k RPMS to around 4.7 or 4.8k k, then I get that nasty lag or flat spot from 4.8k to 5.7k or something, after that, the turbo hits its hardest (quite strong) all the way to 7k RPMS. Find it a bit strange..

So is tuning time roughly 2-3 hours for the R34 and do the workshops do the soldering of the board to the ECU?

cheers RON

You'll say goodbye to this with NIstune

My rule of thumb is you don't need a bigger intercooler unless and until you get a bigger turbo.

i put on a fmic, made a massive difference with throttle responce, then put a exhaust on, helped it flow alot better.

Nistune is a awesome unit, id hate to be the one putting the boards together.. have to soldier 36 or 40 pins to the main ecu..

yeah the flat spot was tuned right out with nistune, unless of course the flat spot your feeling is coil packs... but you'd surely know about it then if it was.

car went from memory 180rwkw before, then after the tune was 216rwkw. and smooth as hell :P

i had blitz FMIC beforehand.

the unit really isn't hard to solder up either, i did mine in well under an hour...

Wow Random_I_Am, ur saying u got like 36Kw power gain with the board and tune, thats awesome, I dont have a fmic,. and EJD001 you getting a massive gain in throttle response could be something to do with you running 16psi? 16psi on stock turbo and you still going sweet, makes me kinda relieved as I thought my 12psi was a bit much.

From what I'm hearing the stock cooler is good for 200rwkw max (or is it 220rwkw??) and a lotta people with the same mods as me are seeing around the 220rwkw mark with a nice board n tune which I dont have yet..

So still dunno if I should bother with a fmic, as I heard it also creates lag with the longer piping. Are the return flow ones much better? :P

My car is booked in for tuesday to get nistune installed and tuned i will get it back on wednesday will let you know how it goes

Hi mate, i have an r34 gtt aswell, also in need of tune and am leaning in the same direction with nistune.

I had a look at nistune.com and it says the type 4 board is $460.00

How much is it costing you to get installed and tuned???

There is no more lag with a FMIC i don't reckon... I used a Blitz Return Flow type and if anything it felt more responsive than the stock one?

as for gaining 36kw, They were off the top of my head. I just had a quick look and i got 214.6rwkw on 11psi.

When i rolled in the AFR's dropped straight off the chart it was so rich with the factory ECU.

Well thing is the actual board just by itself no software ect only costs 260. For 460 i think you also get the software so you can tune it yourself.

I have been quoted between 770-850 supplied fitted and tuned. The variation in price is dependent on if there is any major issues that take a long time to work through (particularly when it is getting tuned) at least that is what he said even though i will happily pay 850.

Another very happy nistune user here. Just front pipe back exhaust, 10psi using turbo tech bleed valve, trust turnflow intercooler made 190rwkw. Seemed a bit low compared to others, but car drives very very well! Super smooth. Been almost a year now and have had no issues at all.

$460 I think is for the software licence (which you dont need ) plus board - the tuner should have the software; for the board alone I was quoted $282

Correct, the $460 is for a Type 4 board AND a single User license, you only need this license if you want to tinker with your car after its' been tuned (or you want to tune it yourself).

Edit: Can someone with a MANUAL R34 GTT, give me the part number for their ECU please? I need to order a board for someone that has lost the sticker off their ECU.. it will be a 27xxx-xxxxx kind of number.. TIA!

P.S. if anyone in Perth is looking to get a board, PM me :P

    • Thanks, I removed the fuse and the relay from the car and made my own circuit with them to test them with a test bulb.  I will look for the wiring diagram and go from there.
    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
