Hi guys, i own an automatic r33 gtst s2.

My friend and i serviced the car the other day, new spark plugs, oil change, oil filter, fuel filter, and now im having issues with the car!!

Now when i go to drive it there is like a long pause before it will engage the gears.

I disconnected the battery and reset the ecu/remapped twice and it helped very slightly.

I go to accelerate now and the revs go up and then after too long a pause it engages the power sort of abruptly. Im not sure what i did wrong... dangerous when i need to get on a roundabout!!

Ok one thing i had noticed i put too much oil in... ive been trying to drain it out but it wont come out!! The sump will give me about a litre then just stop. So i tried again the other day, gave me like 500ml then just stopped completely. I think i still have about a litre too much in there... shouldnt the oil be draining like fairly easily??

any ideas?? thanks in advance

Alex :P

are you talking about the engine oil being too full? if so, just remove the oil cap, drop the sump bolt out and drain it all out and then refill it.

don't see how this could really affect the gearbox though. resetting the ecu shouldn't also have much affect either as it is more than likely something to do with the gearbox oil or the stall converter as to why it takes a while to go into gear.

This doesnt sound good..Id say either some sort of sludge build up is blocking the hole..which isnt good..or did you take your filler cap off when u tried to drain it, maybe its just a vacumn lock but ive never had that happen before..

How much oil did you drain out before you put more in, cause if its not not draining now it probably didnt drain properly before you put new oil in, how much did you put in...

thanx for replies guys,

i didnt remove the oil cap the second time i went to drain oil, prolly why not much came out. When i drained it when we did the service i think maybe 2 and a bit L came out, and i prolly put like almost 4 back in stupid me not realising till i checked the dipstick it was way over. Anyway i did drain like another litre and a half back out but still got a bit to go. Ill prolly put it on a slight incline and try to drain the whole lot then tip it back in like you said.

But yeah the time before this i put standard copper plugs in with 1.1 gap (i used to run .8) and every time i put my foot down the car shat itself, misfiring etc etc so i reset ecu, remapped the timing and it went ok, not great tho. Now with the latest service i went back to 0.8 gap (bcpr6es) and took it for a drive before reseting the ecu and thats when i was having all these issues with the accelerating. I put my foot down, rev meter goes up and nothign happens then suddenly BAM the gear drops in/power engages and it goes - after that initial pause of like 2-3 seconds??! So i reset the ecu / timing and remaped it to the new plugs, but it still does it. Not as bad as before i remapped it (you couldnt even drive it then - too dangerous) but its still doing it to a lesser degree. I go to accelerate and the gear takes its time to engage or the power takes its time to kick in one or the other im not sure which or why!! But now theres maybe a 1-2 second delay. Before all this it would engage almost instantly.

Im not sure where to start lol, should i buy new plugs and start over??

Guys, I'm having the same problem as well. My car seem hesitant as well. The 2-3 seconds lag is worrisome. So whats the solution to this?

I figured that there are few possibilities ranging from a blockage in the air filter; weak battery (Not too sure); blockage in the throttle body or worse, transmission problems.

Hey George

Do you have a 2-3 second lag between the time you press the accelerator and the time the gearbox kicks into gear like the OP or do you have a lag from the time you press the accelerator to the time the revs come up. ?

How does the car feel when your sitting still, in your driveway, is it responsive when you free rev it.

I don't see how a problem with your air filter or your throttle body is going to affect your transmission.

What happens after the lag period ? you put ya foot down -- 2-3 seconds lag -- then the car takes off ,, what happens next, does it run fine through the rev range and change gears perfectly after the initial lag ?

    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
    • Hey lads, reviving an old thread.  As an update, since the last time replied to this thread, ive done mostly suspension. Havent touched the motor except for maintenance. Though upon changing spark plugs, found out i had splitfires pre-installed! Updates: - Got me some stock airbox top cover and snorkel to fit onto the original intake. Should be free of defects - Bought a set of R34 GT-T brakes (not installed yet, going to rebuild + respray in champion blue + white 'Nissan' text) - Bought the last set of bilsteins from @Sydneykid and had them installed. Has been making some sounds on the rear but hopefully should be sorted out after this New Year break. - Regreased front caster rod bushings (poly bushes..) - Rear upper camber arms - Whiteline sway bars (BNF27Z 22mm + BNR11XXZ 24mm).  The rear sway bars are a bit short (ive read 50mm else where) but was still able to get them in.  Anyhows, I reckon suspension is sorted now. Maybe replace bushes (do have a set of front upper control arms from SK not installed yet) but should be okay for now. From now, I'm wanting to start working on the motor, drivetrain etc etc. Still debating on the order to go on and what to buy etc but: - ECU ( Haltech or Link ( Link states that it dont support A/T or AWD functions... Can anyone attest to this? ) - Highflow turbo ( ATR43ss2 ) - Intercooler ( Not decided yet, but cant find many good afoordable ones. Toshi says to opt for crossflow Japanese. Bit difficult this one, unless I get a returnflow Blitz from JJ? ) - Injectors ( Any recommendations ? I do have a nismo FPR ( Thanks SK ) ) - Seats - Tune by either Toshi or DVS To be fair, I did consider just keeping the stock turbo and nistuning it. Sat in a mates stock N, that had something like 200kw, and I reckon that felt more than enough. Maybe I should just go this route ahhaha. Too many choices.... Planning a trip down south, so wanting to just clean things up and make sure it gets to and from in one piece. Anything else specifically I should do before ? Cheers lads  
    • Must be for the car’s lucky charm 🤷🏽‍♂️ She runs fine, but it just seems to take about 1L less. Maybe I’ll have the oil sump dropped at some point to check if there is anything
