im currently having similar problems with mine, especially after boosting it to 9psi. under hard acceleration it seems to be reluctant to go most of the time and will then stutter. i was told it is most definatley my coils, and have also been recommended splitfires. my mechanic said it was because my rea coil was shorting, every now and then when the hood is up you can hear a spark sort of sound which is the short.

hope you figure it out,

will have my coils in a few weeks hopfully that does the trick.

peace

Is there any chance you can let us all no. how you went with the new coils, did it fix the problem or is it still there etc.

thanks

New plugs did the trick :)

hi all, i am have very similar problems with the splurting and hesitation under accelaration have put new twin spark plugs in and had a coilpack replaced when first purchased the car, so i know what a stuuffed coilpack feels like and this certainly is not as bad as that!!

seems to do it only under heavier accelaration, i can gradually feed the accelerator down as the rpm goes up and does tend to miss but have to play with accelerator a bit being careful not to feed to hard or will start choking and spluttering. also get alot of backfiring during gear changes at all types of rpm??????????????

please help unhappy accelarator!!

smidy,

I'm in the process of fixing the same issue in an R33 gtst for a friend. I have changed the plugs and also checked the cat. The issue is most likely still a coil pack, hairline cracks can result in a lesser breakdown issue. larger cracks give a much worse problem. The solution is in a tube of silastic. I'm done for the day on this car so we will glue the coils in the next few days.

yeah my old ones that are soon to be replaced have some silicon like stuff around them, my mechanic thinks it was used to prevent the problem but now just not working, ill keep you all posted when i get my coils in, may still b 2/3 weeks though unfortuantley cash flow has gone.

I fixed the problem now and it was not due to faulty coil packs or spark plugs.

The problem was the boost control valve i was runniing maybe too much boost or incorrect in some way or another , anyway i have takin it off completely and the car is running sweet with full power no hesitations or splurting.

Jack, what mods have been made to your R33?

Sure you weren't hitting fuel cut? if your running 10+psi without a fuel cut defender you will get hesitations/splurting. Also what heat-range plugs are you running?

I was getting hesitations/splurting, fixed it with NGK BKR7E plugs and a wasted-spark setup, car is running mint now with 12psi

Only upgraded and the intercooler and put a blow off valve on it... Im not sure what psi it was running when hesitatiing but it seems that ever since taking the boost valve off and running it stock it works fine with no hesitations.. its has less power but no hesitations. Im running the uridium plugs that they recommend for the skyline r33.

fuel cut defender i dont know what that is, i'm sure that could be the reason for the hesitations. where do i get 1? are they easy to install?

I'm not trying to have ago at you, but it sounds like you don't really know what your doing, I'd recommend you do a lot more research into modifying RB25DET's before you go cranking the boost up.

It probably was the fuel cut making your car have hesitations/splurting, which is a factory safety feature to stop people from over-boosting there cars.

if fuel cut on r33s is anyting like fuel cuts on s13 silvias (i would presume its the same, but i could be wrong), it sounds like a different problem. fuel cut on silvias is almost like violent cutout, its feels different to hessitations/splurting when excelerating.

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
